Section R. 325.10108 - Definitions; S

Rule 108.

As used in these rules:

(a) "Sanitary defect" means a defect that could provide a pathway of entry for microbial contamination into the distribution system or that is indicative of a failure or imminent failure in a barrier that is already in place.
(b) "Sanitary survey" means an evaluation, including an on-site review of a waterworks system or a portion of the waterworks system, including all of the following applicable components for existing or potential health hazards for the purpose of determining the ability of the public water supply to produce, treat, and distribute adequate quantities of water meeting state drinking water standards:
(i) Source.
(ii) Treatment.
(iii) Distribution system.
(iv) Finished water storage.
(v) Pumps, pump facilities, and controls.
(vi) Monitoring, reporting, and data verification.
(vii) System management and operation.
(viii) Operator compliance with state requirements.
(c) "Seasonal supply" means a noncommunity water supply that is not operated as a public water supply on a year-round basis and starts up and shuts down at the beginning and end of each operating season.
(d) "Service connection" means a direct connection from a distribution water main to a living unit or other site to provide water for drinking or household purposes.
(e) "Service line" means the pipe from the discharge of the corporation fitting to customer site piping or to the building plumbing at the first shut-off valve inside the building, or 18 inches inside the building, whichever is shorter.
(f) "Service line sample" means a 1-liter sample of water that has been standing for not less than 6 hours in a service line.
(g) "Shift operator" means a certified operator, other than the operator in charge, who is in charge of an operating shift of a waterworks system.
(h) "Single-family structure," for the purpose of lead and copper control, means a building which is constructed as a single-family residence and which is currently used as either a residence or a place of business.
(i) "Small water supply" or "small water system," for the purpose of lead and copper control, means a public water supply that serves fewer than 3,301 persons.
(j) "SOC" means synthetic organic chemical.
(k) "Source" means the point of origin of raw water or means treated water that is purchased or obtained by a public water supply, by a water hauler, or by a person who provides bottled water.
(l) "State drinking water standards" means quality standards setting limits for contaminant levels or establishing treatment techniques to meet standards necessary to protect the public health.
(m) "Static water level" means the distance measured from an established datum at or above ground level to the water surface in a well which is not being pumped, which is not under the influence of pumping, and which is not flowing under artesian pressure.
(n) "Subpart H system" or "subpart H supply" means a public water supply using surface water or ground water under the direct influence of surface water as a source.
(o) "Suction line" means a pipe or line that is connected to the inlet side of a pump or pumping equipment.
(p) "Supplier of water" or "supplier" means a person who owns or operates a public water supply, and includes a water hauler.
(q) "Surface water" means water that rests or flows on the surface of the ground.
(r) "SUVA" means specific ultraviolet absorption at 254 nanometers (nm), an indicator of the humic content of water. It is a calculated parameter obtained by dividing a sample's ultraviolet absorption at a wavelength of 254 nm (uv254) (in m-1) by its concentration of dissolved organic carbon (DOC) (in mg/l). Therefore, SUVA units are l/mg-m.
(s) "System with a single service connection" means a public water supply that supplies drinking water to consumers through a single service line.
