Document Description
Amador Water Agency- Sutter Creek constructed two 44-foot wide, 24-foot tall, 260,000-gallon backwash tanks, and installed a new polymer feed building. Within the polymer feed building a new polymer drum and feed system was installed to treat the backwash water pumped to the backwash tanks. A new open-air polymer station for solids handling was also installed that included a polymer preparation skid, a 500-gallon sludge mixing tank, and two sludge dewatering containers on a concrete pad. A new 96 foot^2 pumping station with two backwash return pumps and two sludge dewatering pumps were also added. Piping was installed for sampling, fire flow, a by-pass line, to provide coagulant to the backwash, and to transport backwash to the backwash tanks. Piping was also installed from the backwash tanks to the skid, sludge tank, dewatering containers, and existing backwash sump. For return liquid, piping was installed from the backwash sump back to the backwash tanks. Piping was also installed from the backwash tanks to transport skimmed liquids back to the existing treatment system. An electrical building, flow meters, pressure transducers, a turbidity meter, an electrical panel, electrical lines, and lights were also installed. Modifications were also made to the wastewater treatment backwash and clarifier flush operations within the existing treatment plant. The total area of soil disturbance consisted of .852 acres. Construction was completed on April 5, 2019. Operation of facilities will recycle 200-acre feet of filter and clarifier wash water per year. The non-hazardous sludge waste produced by the operation of the facilities will be transported to a landfill or used as on-site fill material.
