Section 445A.54036 - Requirements for design of new facility

Universal Citation: NV Admin Code 445A.54036

Current through September 16, 2024

1. The design for a new facility to treat groundwater must:

(a) Be free of structural and sanitary hazards.

(b) Provide for protection against pollution and contamination by backflow.

(c) Provide equipment for measuring and recording flow.

(d) Be designed to mitigate the effects of events such as earthquakes, fires, floods, freezing and sabotage that are reasonably foreseeable.

(e) Provide access for inspection, maintenance and monitoring of all unit processes.

(f) Provide, if required by the selected treatment process, for a coagulation process that includes rapid chemical mixing and is based on pilot plant or laboratory scale or equivalent results that demonstrate the effectiveness of the coagulant chemicals over the full range of water quality conditions expected.

(g) Provide, if filtration is required:
(1) For filter-to-waste for each filter unit;

(2) Backwash rates and facilities for surface or subsurface wash using air, water or a combination of these to clean the filter; and

(3) Treatment for the removal of solids from filter backwash water if the water is recycled into the treatment process. Recycled backwash water must be returned to the headworks of the treatment plant.

(h) Provide equipment for disinfection which is of proper size for the full range of expected conditions of flow and which is capable of automatic feeding accurately at all rates of flow.

(i) Provide for operation of the treatment plant without frequent shutdowns and start-ups.

2. As used in this section, "filter-to-waste" means a provision in the filtration process to allow the water that was filtered first to be wasted or reclaimed.
