(a) All plans for water works and treatment facilities shall have a suitable title showing the following: - (i) Name of owner and location of project.
- (ii) North arrow and drawing scale.
- (iii) Name, Wyoming registration number, and seal or signature of the engineer.
(b) All plans shall contain a site plan of the proposed project with topography and boundaries of the project. Datum used shall be indicated.
(c) Water lines. Plans for transmission and distribution lines shall include: - (i) A detailed plan view at a legible scale of each reach of the water line showing all existing and proposed streets, adjacent structures, physical features, and existing locations of utilities. The location and size of all water lines, valves, access manholes, air-vacuum release stations, thrust blocking, and other appurtenances shall be indicated. Pertinent elevations shall be indicated on all appurtenances.
- (ii) Profiles of all water lines shall be shown on the same sheet as the plan view at legible horizontal and vertical scales, with a profile of existing and finished surfaces, pipe size and material, valve size, material and type. The location of all special features such as access manholes, concrete encasements, casing pipes, blowoff valves, airvacuum relief valves, etc., shall be shown.
- (iii) Special detail drawings scaled and dimensioned to show the following:
- (A) The bottom of the stream, the elevation of the high- and low-water levels, and other topographical features at all locations where the water line is near or crosses streams or lakes.
- (B) Cross-section drawing of the pipe bedding.
- (C) Additional features not otherwise covered by specifications.
- (iv) Location of any sewer lines within 30 feet (9 m) horizontally. Sewers that cross water lines shall be shown on the profile drawings.
(d) Storage tanks, pumping stations and treatment facilities. Plans shall be submitted showing the relation of the proposed project to the remainder of the system. Layouts and detail plans shall show the following: - (i) Site location and layout including topographic and physical features, proposed arrangement of pumping or treatment units, existing facilities, existing and proposed piping and valving arrangements, access drive, power supply, fencing, embankments, clearwells, waste and sludge ponds, etc.
- (ii) Schematic flow diagram(s) and hydraulic profile(s) for facility treated water, and flow diagram for sludge and wastewater flows.
- (iii) Plan(s) and section view(s) of each treatment facility process unit with specific construction details, features and pertinent elevations. Details of each unit should include, but are not limited to: inlet and outlet devices, baffles, valves, arrangement of automatic control devices, mixers, motors, chemical feeders, sludge scrapers, sludge disposal, or other mechanical devices.
(e) Wells. Plan and profile drawings of well construction shall be submitted showing diameter and depth of drill holes, casing and liner diameters and depths, grouting depths, elevation and designation of geological formations, water levels, and other details to describe the proposed well completely.
(f) Specifications. Technical specifications shall accompany the plans for new water lines, pump stations, treatment facilities, wells, or additions/modifications to existing systems or facilities. Where plans are for extensions to water distribution systems, the specifications may be omitted, provided it is stated that the work is to be constructed under specifications authorized by the Water Quality Division. Specifications on file must conform to this standard. The specifications accompanying construction drawings shall include: - (i) Identification of construction materials.
- (ii) The type, size, strength, operating characteristics, rating or requirements for all mechanical and electrical equipment, including machinery, valves, piping, electrical apparatus, wiring and meters; laboratory fixtures and equipment; operating tools; special appurtenances; and chemicals, when applicable.
- (iii) Construction and installation procedure for materials and equipment.
- (iv) Requirements and tests of materials and equipment to meet design standards.
- (v) Performance tests for operation of completed works and component units.
- (vi) Specialized requirements for tests, analyses, disinfection techniques, and other special needs.
- (vii) Requirements for well construction and testing. The collection of the following must be recorded and reported to the Wyoming Department of Environmental Quality, Water Quality Division.
- (B) Well construction data. Well construction data shall include screen locations, size of screen openings, screen intervals, accurate records of drill hole diameters and depths, assembled order, size and length of casing and liners, casing wall thickness, grouting depths, formations penetrated, water levels, and location of any blast charges.
- (C) Well test data. Well test data shall include test pump capacity-head characteristics; static water level; depth of test pump setting; time of starting and ending each test cycle; pumping rate; pumping water level; drawdown; and water recovery rate and levels.
(g) Technical specifications shall require that all water service connections will be provided with backflow prevention devices in accordance with the requirements of Section 14(i) of these regulations.
