Section 150-7-7 - Utility Facilities; Service Pipes; Extension of System7.1. Adequacy of facilities. 7.1.1. Construction and maintenance of plant. -- A utility shall at all times construct and maintain its entire plant and system in such condition that it will furnish safe, adequate and continuous service.7.1.2. Inspection of plant. -- A utility shall inspect its plant and facilities in such manner and with such frequency as is necessary to ensure a reasonably complete knowledge as to their conditions and adequacy at all times. Such inspections must comply with the requirements of the legally applicable Minimum Federal Safety Standards (Federal Occupational Health and Safety Administration) and the standards of the Bureau for Public Health and the Department of Environmental Protection (as applicable).7.1.3. Records of conditions. -- Records necessary for the proper maintenance of the system and in accordance with the Bureau for Public Health and the Department of Environmental Protection (as applicable), and the Minimum Federal Safety Standards shall be kept of the conditions found. In special cases, a more complete record may be specified by the Commission.7.1.4. Records of operation. -- A utility shall keep a record of the operation of its plant, which, so far as practical, shall show sufficient details of plant operation as is necessary to substantially reproduce the daily history of its operation. The utility shall also maintain the records in accordance with the requirements of the Minimum Federal Safety Standards and Bureau for Public Health and Department of Environmental Protection (as applicable).7.1.5. Reports to Commission. -- A utility shall, upon request of the Commission, file with the Commission a statement regarding the condition and adequacy of its plant, equipment, and facilities, and of its operations and service in such form as the Commission may require.7.1.6. Bureau for Public Health Standards. -- All extensions, service connections and modifications to a utility's plant must meet applicable design standards established by the West Virginia State Bureau for Public Health in addition to these rules.7.1.7. Dead ends. -- A utility should avoid "dead ends" in the utility's distribution mains so far as possible. If "dead ends" exist the utility shall provide facilities for flushing.7.2. Utility Service Pipe. 7.2.1. Where the service pipe is required for the immediate and continuous use for general service to premises abutting the public street or right-of-way in which mains are located, the utility will furnish, install, and maintain the utility service pipe and appurtenances between the main in the street up to the customer's point of service at or near 90 degrees to the main. Provided, all utility service pipes and appurtenances shall be installed only by the utility unless by prior written agreement.7.2.2. The utility shall determine the location of the utility service pipe.7.2.3. The utility will specify the size, kind, quality and location of all materials used in the utility service pipe.7.2.4. The utility shall install and maintain, at its own cost and expense, all of the utility service pipe regardless of the side of the road on which the customer is located in reference to the main line. The utility shall designate the point of service on the customer's side of the road.7.2.5. The utility shall not make any charge for furnishing and installing any permanent service connection, meter or other appliance necessary to deliver and measure the water furnished unless the utility has prior approval of the Commission to charge a tap fee and the same is set forth in the utility's tariff on file with the Commission.7.2.6. The utility's service pipe shall remain under the utility's sole control and jurisdiction.7.2.7. The customer shall not attach any fixtures to, or make any branches in, the utility service pipe between the point of service and the distribution main. Violation of this rule may result in termination of service pursuant to these rules.7.2.8. A utility shall install temporary service connections for construction or other temporary purposes or connections for private fire service at the cost of the applicant.7.2.9. A water utility shall adopt standard methods of meter installations where practicable and file a written description and drawings to provide a clear understanding of the requirements.7.3. Customer Service Pipe. 7.3.1. No customer, plumber, company owner or any agent shall connect to the utility's main or to any utility service pipe, or extend the pipes therefrom to any premises for the purpose of securing water service, until application has been made therefor to the utility as provided in these rules and the utility has granted permission in writing.7.3.2. Once a utility grants an application for service, the customer shall install and maintain the customer service pipe.7.3.3. The utility's authorized employee shall inform the customer of the location of the point of service. The customer shall install the customer service pipe to the point of service after which the utility will install the utility service pipe from the distribution main to the point of service.7.3.4. The customer shall also install and properly maintain in good working condition a stop and waste cock of a type approved by the utility on the customer's service pipe immediately inside the foundation wall in a readily accessible location and in a place protected from the possibility of freezing and so placed that it will shut off and drain all plumbing within any and all buildings in the premises.7.3.5. Where the utility's service pipe is already installed to the point of service, the customer shall connect with the utility service pipe as installed.7.3.6. The customer's service pipe shall be installed in a workmanlike manner, shall conform to all reasonable rules and regulations of the utility, and shall be maintained by the customer at his own expense.7.3.7. The utility will specify the size, kind, quality and location of all materials used in the customer's service pipe and the customer shall comply with those specifications.7.3.8. A customer must maintain his service pipe in good condition and free from all leaks and defects, at the customer's cost and expense. A customer's failure to comply with this rule may result in termination of service pursuant to these Rules.7.3.9. The customer's service pipe shall: be laid below the frost line at all points; be placed on firm and continuous earth so as to give unyielding and permanent support; and be installed in a trench at least two (2) feet in a horizontal direction from any other trench wherein gas pipe, sewer pipe, or other facilities, public or private, are or are to be installed.7.3.10. Except in the case of long-service lines, a customer's service pipe shall not pass through or across any premises or property other than that to be served. If a property served as of September 14, 2021 is later subdivided resulting in the original customer's service pipe crossing the subdivided property that will be occupied by a new customer, the original customer and new customer must have separate service pipes. The original customer must obtain a right-of-way for the original customer's service pipe on subdivided sections of property before title of such section passes to a new owner.7.3.11. The customer's service pipe and all connections and fixtures attached thereto shall be subject to the inspection of the utility before the water will be turned on, and all premises receiving a supply of water and all service pipes, meters and fixtures, including any and all fixtures within the said premises, shall at all reasonable hours be subject to inspection by any duly authorized employees of the utility.7.3.12. The utility shall make changes and bear the full costs of changes in the customer's service pipe or meter location required due to changes in grade, relocation of mains, and other causes not related to the customer. The customer shall bear the full costs of changes in service pipe or meter location desired by the customer for the customer's convenience.7.3.13. The customer shall not attach any fixtures to, or make any branches in, the customer service pipe between the point of service and the premises served. Violation of this rule may result in termination of service pursuant to Water Rule 6.8.7.3.14. There shall be no more than one (1) customer service pipe required to serve a single premises and each premises shall be supplied through an independent customer service pipe, unless otherwise approved by the utility in writing.7.4. Long service lines. 7.4.1. To assure the orderly development of its system, and to provide adequate service to its customers, the utility should ordinarily provide water service only at the property line of the customer requesting service, and in those instances where the utility's service does not extend to the customer's property line, the utility should construct an extension in accordance with Water Rule 7.5. In unusual and exceptional cases where the property line of the customer requesting service is an excessive distance from the existing main of the utility, and the cost to be borne by the prospective customer under Water Rule 7.5. is prohibitive, and there is no reasonable prospect of further growth and development in the area, or for any one of the above reasons, the utility may serve the customer by installing a meter in the utility's right-of-way at its main nearest the customer's property, and connecting the meter to the customer's privately owned service line. The customer shall extend his customer service line to an existing distribution main of the utility and shall be solely responsible for service beyond the meter. The utility shall not serve other customers from a long service line.7.4.2. If a road crossing is necessary to serve the customer, the utility shall install that portion of the line crossing under the road and shall locate the meter on the customer's side of the road; provided that the utility's distribution main lies within or adjacent to the existing road right-of-way. The customer shall be required to provide evidence to the utility that proper easements or rights-of-way have been obtained. Standards of service received by the customer shall be determined at the metering point. The customer shall not permit others to connect to the customer's water lines or receive water service from the customer's privately owned service line. In the event the utility's main is later extended to the customer's property line under Water Rule 7.5., the customer shall discontinue the use of his privately owned service line and shall pay all costs and charges authorized by the rules of the Commission and the rules and tariffs of the utility for water service from such extension, the same as if the customer had not previously laid and received service through a private service line. The provisions of this rule shall apply to all persons now or hereafter receiving water service through a privately owned service line extending from the utility's main to the property to be served.7.5. Extension of mains to serve new customer(s) and customers currently served under Water Rule 7.4. 7.5.1. A water utility, whether publicly or privately owned, is under a public service obligation to extend its mains, and its plant and facilities to serve new customers within its service area who may apply for service.7.5.2. The utility shall make extensions in all cases in which the public convenience and necessity require the service, construction problems are not unusual or burdensome, and the extensions appear to be economically feasible, except that a utility shall first consider an application for an alternate main extension when applicable._7.5.3. For any proposed extension of mains to be installed by a utility, a reasonable relationship should exist between the per customer investment to serve new customers and the per customer net investment to serve existing customers.7.5.4. A utility shall make every effort to install its distribution main in the public road right-of-way or in a utility right-of-way abutting the public road right-of-way.7.5.5. Extensions for general water service.7.5.5.a. The utility will respond to all inquiries regarding new water service, whether oral or written, by explaining all available options for obtaining service under these rules, including the option of an alternate main extension agreement, pursuant to Rule 7.5.8.g.7.5.5.b. When extensions other than those made pursuant to Rule 7.5.8.g. are built, the customer pays for the customer service pipe and the utility pays for the utility service pipe.7.5.5.c. The utility will, upon written request for service in the form of Water Form No. 4, by a prospective customer or group of prospective customers located in the same neighborhood, or a customer currently served under Water Rule 7.4., determine the necessary size of main required to give service and make an estimate of the cost of providing the requested service, using the form of Water Form No. 5, including pipe, valves, fittings, necessary materials, permits, costs incurred by the utility when the utility externally contracts for the construction of the extension, or internal labor costs, provided such internal or external costs are not recovered in existing rates, and other applicable related costs. When a road crossing(s) is (are) necessary to serve the customer(s) requesting service, the cost estimate shall not include costs attributable to extending the main across the first road (closest to the already existing main), but shall include the costs of installing the main across a second and any subsequent road(s). The utility will provide the written estimate calculated using Water Form No. 5 to the customer in the form of Water Form No. 6, no more than forty (40) days from the receipt by the utility of the written request for service, except that the utility will provide the written estimate to the customer no more than twenty (20) days following a denial of a request for an alternate main extension agreement pursuant to Rule 7.5.8.g. The written estimate shall include an estimated construction start date and an estimated time of construction. If the prospective customer believes that any part of the estimate is unreasonable, the customer is free to pursue an informal request for assistance from the Commission staff or to file a complaint with the Commission. Further, the utility and the customer shall execute a Main Line Extension Agreement. Commission Staff may be consulted to provide assistance and sample forms. The agreement must include as an attachment a copy of this extension rule. The utility shall keep an executed copy of their agreement for at least six (6) years. The length of the extension required shall be that length required to extend from the new proposed service area to the nearest point of connection to the utility system having sufficient excess capacity to provide service at maximum demand.7.5.5.d. Unless service is to be provided by a long service line pursuant to Water Rule 7.4., whenever the utility is required to extend service from an existing distribution main to property that does not immediately abut the utility's right-of-way or the public road that contains the distribution main, the extension shall be considered a main extension and cost responsibility shall be determined under Water Rule 7.5.5.7.5.5.e. Where the cost of the extension does not exceed the estimated total net revenue, as calculated below, from hydrants and prospective customers whose service pipes will immediately be connected directly to the extension and from whom the utility has received applications for service upon forms provided by the utility for this purpose, the utility will install, at its own cost and expense, the necessary extension; provided that the patronage or demand will be of such permanency as to warrant the capital expenditure involved. 7.5.5.e.1. Net annual revenue shall be gross annual revenue minus an amount equal to the excess usage leak adjustment rate approved for the utility times the applicant's usage used for purposes of this rule, with this difference further reduced for any revenue based taxes.7.5.5.e.2. The utility will base revenue on the average usage by customer class at the time of the extension, unless circumstances of the applicant show this would result in significant error. For non-residential units, the utility will base annual revenue on typical consumption for comparable units published by the American Water Works Association.7.5.5.e.3. Estimated total net revenue for private, for profit, utilities will be initially calculated as six (6) times estimated net annual revenue. Each such utility shall file for a line extension multiplier within twelve (12) months of the effective date of these rules.7.5.5.e.4. The utility-specific line extension multiplier for private, for-profit, utilities shall be based on one (1) divided by the utility's net fixed charge rate. The net fixed charge rate shall equal a function of the utility's weighted cost of capital, applicable income tax rates, and the Commission approved depreciation accrual rate.7.5.5.e.5. Estimated total net revenue for associations, municipal, and public service district utilities will be calculated as five (5) times estimated net annual revenue. If the Commission approved excess leak adjustment for the utility fails to include all of the incremental costs of serving a new customer that should properly be netted out from the total revenues of the utility, the utility may apply to the Commission for a determination of the proper amount to be deducted from gross revenues to arrive at an appropriate determination of net revenue.7.5.6. Extensions beyond the limit of utility-financed extensions of general water service and public fire service.7.5.6.a. If the utility-estimated cost of the proposed extension required in order to furnish general water service exceeds the utility's estimate of total net revenue as determined by Water Rule 7.5.5.d., the utility will make the extension if the applicant or the applicant's authorized agent contracts for the extension and deposits in advance with the utility the estimated cost of the extension over and above the limit of the utility-funded portion of the extension. The utility shall not pay nor be liable for any interest on such cash deposits. The utility shall make the extension after receiving the cash deposit. The utility shall, for each bona fide new customer who, within a period of ten (10) years from the making of such extension, directly connects to the extension between its original beginning and the original terminus, refund to the original depositor(s), an amount equal to the estimated total net revenue of the new customer as determined by Water Rule 7.5.5.d., but in no event shall the aggregate refund made to the depositor(s) exceed the original deposit. Provided that associations, public service districts and municipal water utilities may elect to refund the estimated amount over a period of five (5) years making payments no less frequently than every six (6) months.7.5.7. Alternate depositor-financed extension plan.7.5.7.a. Qualifying utilities. -- The above requirements notwithstanding, the utility may decline to finance the portion of a requested extension that would be utility-funded if it can demonstrate that it has no prospect of any reasonable internal or external financing through commercial loans, grants, or through an installment arrangement with an entity installing the extension or providing the necessary materials.7.5.7.a.1. If the utility declines to finance the portion of a requested extension that would be the financial responsibility of the utility, the utility shall file for a waiver of the extension rule within sixty (60) days of the written request.7.5.7.a.2. Before filing for a waiver, the utility must first estimate the extension costs.7.5.7.a.3. A request for a waiver by a utility shall be accompanied by supporting documentation justifying its request, including cost estimates, documentation of inability to finance, internally or externally, through commercial loans, grants or an installment arrangement with an entity installing the extension or providing the necessary materials, and the proposed agreement.7.5.7.a.4. If the Commission finds that the utility has reasonably declined to finance the portion of the requested extension that would otherwise be utility-funded, the Commission shall authorize the use of the alternate depositor-financed extension plan as described below.7.5.7.b. Description of alternate depositor-financed extension plan. -- Under the alternate depositor-financed extension plan, the utility shall make the extension after: 7.5.7.b.1. receiving a cash deposit equal to the full amount of the extension cost; and7.5.7.b.2. agreeing to give the depositor(s), who is a customer, a monthly bill credit totaling one hundred percent (100%) of the actual net bill(s) from the date service is initiated and until the total credits given equal the estimated total net revenue as defined in Water Rule 7.5.5.d.; and7.5.7.b.3. agreeing to refund to the original depositor(s) an amount equal to the estimated total net revenue as defined in Water Rule 7.5.5.e. of each bona fide customer, other than the depositor(s), who, within a period of ten (10) years from the construction of the extension, directly connects to the extension between its original beginning and the original terminus. The refund may be spread out over a five (5) year period with the utility making payments no less frequently than every six (6) months. The refunds shall continue until the total refunds given equal the estimated total net revenue as defined in Water Rule 7.5.5.d.7.5.7.c. In no event shall the total refund made to the depositor(s) under Water Rule 7.5.7. exceed the original deposit of the depositor(s).7.5.7.d. The utility shall not pay nor be liable for any interest on the cash deposits associated with line extensions.7.5.8. General Provisions.7.5.8.a. If the actual cost of the extension is less than the estimated cost, the utility will refund the difference as soon as the actual cost is ascertained, but in no event later than ninety (90) days after completion of construction of the extension. When the actual cost of the extension exceeds the estimated cost, the utility will bill the depositor for the difference between the estimated and the actual cost. The utility will not pay interest on the applicant's payment or on any balance that is refunded.7.5.8.b. In estimating the cost of an extension, the utility will base the estimate on the diameter of the pipe to be used; provided that the estimated cost to the customer or customers shall not be based on a pipe diameter greater than the diameter of the main from which the extension is to be made, unless actual consumption estimated for the proposed customer or customers requires a larger pipe.7.5.8.c. Extensions made under this rule shall be and remain the property of the utility.7.5.8.d. The utility reserves the right to further extend its distribution mains from and beyond the extension made under this rule, and the depositor or the depositor's agent paying for an extension shall not be entitled to any refund for customers attaching to such further extension or branch mains.7.5.8.e. In determining the length of water line to be installed in an urban area when land is subdivided into lots, the main, or water line (if installed by an entity other than a utility), shall be extended to fully cover the frontage of the property, and if the last lot to be served is a corner lot the terminal point of the extension made hereunder shall be located so that the water line ties in with the intersecting street. If there is no main located in the intersecting street, the terminal point of the extension shall be located at the nearest street line of the intersecting street. In rural areas or open land areas, the extension required will be that length necessary to adequately serve the applicant.7.5.8.f. Before water lines are laid in any new subdivision, the road surface shall be brought to the established sub-grade as determined by the agency having jurisdiction.7.5.8.g. Alternate Main Extension Agreements.7.5.8.g.1. A utility may enter into an agreement with an applicant that complies with the Commission approved checklist attached hereto as Water Form No. 7, providing an alternate plan for a main extension. Commission Staff may be consulted to provide assistance and sample forms.7.5.8.g.2. An applicant desiring to enter into an alternate main extension agreement should submit a written request to the utility.7.5.8.g.3. A utility will, within twenty (20) days of receipt of the written request to enter into an alternate main extension agreement, consider the request and submit a response to the applicant indicating the utility's approval or denial of the request.7.5.8.g.4. If the utility denies the request to enter into an alternate main extension agreement, the utility will provide the applicant with a detailed explanation of its decision and explain the available options for obtaining service under these rules. If the applicant believes that a denial is unreasonable, the applicant is free to pursue an informal request for assistance from the Commission staff or to file a complaint with the Commission.7.5.8.g.5. In providing an alternate plan for main extensions a utility may not discriminate between customers whose service requirements are similar.7.5.8.g.6. An alternate main extension agreement shall be filed with and approved by the Commission prior to implementation or execution of the agreement by any of the parties. The agreement shall include the name, address and phone number of the parties to the agreement. The agreement shall also include a provision explaining why the utility is not funding the extension. The agreement must attach a copy of Water Rule 7.5 and a statement signed by the prospective customer that the customer has reviewed and understands the provisions of Water Rule 7.5.7. which entitle a customer to refunds and that the customer knowingly waives such rights, if applicable. Failure to obtain Commission approval will result in the loss of the right to obtain reimbursement from the utility. If an entity other than the utility constructs the extension, upon completion of construction and proper utility inspection of the extension, the utility shall initiate service only after proper transfer of title to all facilities including property, plant and rights-of-way incidental to the furnishing of utility service.7.5.8.h. Contract for service. -- A utility is not required to make free extensions or refunds as described in this rule unless those to be served by such extension shall guarantee to the utility that they will take water service at the premises within thirty (30) days after water service is available or as otherwise mutually agreed in a user's agreement.7.5.8.i. Construction conditions. -- A utility will undertake construction of line extensions, as provided in this rule, promptly after all applications are completed, necessary right-of-way agreements or rights of entry are delivered to the utility, and all prospective customers have signed contracts.7.5.8.j. Right-of-Way. 7.5.8.j.1. If construction of an extension involves the acquisition of a private right-of-way, then the prospective customer shall attempt to secure the right-of-way and deliver it to the utility free of cost before construction of the extension begins.7.5.8.j.2. If, however, it is not reasonably possible for the prospective customer or customers to secure the right-of-way, and the construction of an extension involves the utility's incurring expense for right-of-way easements, either by purchase or condemnation, the utility will add those costs to the total cost of the extension.7.5.8.j.3. As a condition to obtaining a main extension, property owner or developer must grant the utility the necessary easements to allow the utility to make future extensions into unserved areas. The property owner or developer will grant the necessary easements without requiring the utility to pay additional consideration for the additional easements to the property owner or developer. If the property owner or developer is unwilling to grant the additional easements, the utility shall not be required to extend its main to serve the property owner or developer.7.5.8.k. Upon the proper filing of a Tariff Rule 42A, 42R, 42T, 19A, or 19R rate case or a certificate case filed pursuant to W. Va. Code § 24-2-11 by the utility, the utility may seek to include in its tariff a Capacity Improvement Fee, Capacity Assurance Fee or such other fee or charge designed to raise capital to cover the cost of future capacity expansion to be assessed against customers or entities creating those costs.7.5.9. Community infrastructure investment agreements with municipal utilities and public service districts. 7.5.9.a. Municipal utilities and public service districts may enter into "community infrastructure investment agreements" in accordance with the provisions of W. Va. Code § 22-28-1 et seq.7.5.9.b. A utility that has entered into "community infrastructure investment agreements" pursuant to W. Va. Code § 22-28-1 et seq. shall maintain separate books and records for the project areas involved in the agreements. For purposes of this section, the project areas for which separate books and records are required include plant upgrades and stand alone systems.7.5.9.c. A utility that has entered into "community infrastructure investment agreements" pursuant to W. Va. Code § 22-28-1 et seq. shall file (i) a copy of the certificate of appropriateness, (ii) a copy of the community infrastructure investment agreement, and, if necessary, (iii) a new tariff containing rates applicable to the new service area. The utility shall file the required documents with the Commission no later than thirty (30) days of the date the project is transferred to the utility.7.5.9.d. If rates for the new customers served by a public service district project are higher than the rates for the public service district's existing customers, the public service district shall, within ninety (90) days of the date the project is transferred to the public service district, make a formal rate application with the Commission in order to justify the higher rates to the new customers. A municipality shall enact an ordinance increasing rates, if necessary, within ninety (90) days of the date the project is transferred to the municipality.7.6. Water Losses. 7.6.1. Each utility shall determine either by actual measurement or by estimate the amount of "Water Losses" as defined in Water Rule 3.17. in each division of its system and report, separately, to the Commission in its annual report. If the reported Water Losses are in excess of fifteen percent (15%) of the water supply delivered into the transmission and distribution system on an annual basis, the utility will state the remedial actions it proposes to take. A utility may seek assistance from the Commission regarding remediation of water losses in excess of fifteen percent (15%).7.7. Cross connections and back flow prevention regulations. 7.7.1. See West Virginia Bureau for Public Health legislative rules pertaining to cross-connections and backflow prevention codified at 64CSR15 (effective March 13, 2004).7.7.2. All utilities that have adopted a standard or uniform cross-connection and backflow program pursuant to §64-15-8.2 of the West Virginia Code of State Rules must file the details of such programs with the Commission. Such programs will be approved as filed unless it can be shown that the program violates an existing Commission rule.7.8. Standard pressure. 7.8.1. The utility shall ensure that every utility customer receives a "standard pressure" within the Commission-established minimum and maximum pressure limits. When possible, a "standard pressure" shall be calculated as the static pressure based on the difference in elevation between the base of the storage tank and meter box or point of service. Where this method of calculating a customer's "standard pressure" is not practical, the utility will use the actual engineering design of the system or common engineering methods to determine the "standard pressure" at the point of service. A utility shall not allow pressure to fluctuate more than fifty percent (50%) above or fifty percent (50%) below such "standard pressure" during normal operating conditions. Pressure variations outside the limits specified are not a violation of this rule if they are infrequent and arise from unusual or extraordinary conditions, or arise from the operation of the customer's equipment. This rule shall be interpreted to permit a different "standard pressure" calculation for each customer due to varying elevations.7.8.2. A utility should establish an elevation in each pressure district above which it cannot provide the minimum pressure required by this rule. A utility shall post notice of that elevation in a prominent place in the public offices of the utility. A utility may furnish new service to customers above this elevation if the customer is fully advised of the conditions under which average service may be expected, and the customer's agreement is secured in writing. The utility may require in the agreement that its terms shall be binding on future customers served at the same location under similar circumstances; provided that the agreement be recorded with the appropriate county clerk. This waiver shall not prevent the Commission from requiring a better service when, upon investigation, it appears that improvements should be made.7.8.3. A utility shall not make changes to the standard pressure or pressures adopted for its customers without the approval of the Commission.7.8.4. A customer's pressure shall be no less than twenty (20) p.s.i. at peak demand on system or thirty (30) p.s.i. static pressure at the terminus of the utility's service line (meter box or curb box) unless the customer has waived this requirement. For all new customers desiring service on and after October 24, 2003, a customer's pressure shall be no greater than one hundred thirty-five (135) p.s.i. unless the customer has waived this requirement. The utility shall keep on file all the aforesaid waivers, in accordance with Water Rule 4.1.7.9. Quality of water.7.9.1. Purity. -- All water furnished by a utility for domestic use, shall be pure, wholesome, potable and in no way dangerous to the health of the consumer.7.9.2. Health Department. -- Every water utility shall comply with the rules of the Bureau for Public Health governing purity of water, testing of water, operation of filter plants and such other rules they may prescribe, pursuant to law, having as their ultimate end the purity of water.
