Improvement District No. 1, Water System Rehabilitation Project

Improvement District No. 1, Water System Rehabilitation Project

The Improvement District No. 1 water system consists of hard rock wells, river well, pumps, water treatment plant, pipelines, and storage tanks. Many portions of this system are 50 years old. The District has been experiencing numerous leaks in the pipelines and storage tanks, resulting in significant expenditures for repairs. The area has limited groundwater supplies and the leaking system aggravates this limited water supply. The project will replace the existing distribution syste, drill wells, install a steel water storage tank, valves, fire hydrants, water services, paving and appurtenances. The existing river well is treated with a pressure filter system. the new drinking water requirements do not allow the existing in-line filtration process and a pressure clarifier will need to be added upstream of the existing pressure filters. The existing filters will be inspected and repacked with new filter media if found to be necessary. The backwash from the pressure clarifier will be directed to the existing backwash water discharge from the filters and into an adjacent seasonal drainage channel. The hard rock well capacity drops off during the summer and fall months and the river well is used to supplement the flow to meet system demands. The backwash water from the existing pressure filters and proposed clarifier will be limited to times when the channel is dry. An additional 10,000 gallon polyethylene or galvanized tank will be added at the water treatment plant to increase the contact time for disinfection of the river well discharge.
