| (a) Plans and specifications for a reclaimed water production facility must meet the design criteria and the operation, maintenance, and safety requirements in Chapter 217 of this title (relating to Design Criteria for Wastewater Treatment Systems) except for redundant treatment units or processes, including power supplies, if the design incorporates sufficient provisions to ensure the effluent quality meets the required limits in the event of a failure of a power supply or a treatment unit or process. (b) The reclaimed water production facility must be designed to convey all wastewater to the domestic wastewater treatment facility any time the facility is not in operation. (c) The reclaimed water production facility must be designed to convey all sludge received or produced by the facility to the domestic wastewater treatment facility. Sludge may be held in an aerated storage vessel for discharge to the collection system if the entire sludge contents are completely discharged at least once within every 24-hour period. (d) The reclaimed water production facility must be designed and operated to minimize odor and other nuisance conditions. (e) The following treatment processes and units are prohibited: (1) unaerated primary treatment units (including Imhoff tanks and primary clarifiers); (2) trickling filters; (3) pond or lagoon treatment systems; (4) flow equalization basins; and (5) unenclosed screenings storage containers. |
