Giles County PSA Water System

Giles County PSA Water System

For many years, the citizens of Giles County were in need of a reliable public water system. The only public water supplies were located in the Towns; Glen Lyn, Rich Creek, Narrows, Pearisburg, and Pembroke. A regional project was undertaken over the course of many years. The goal of the regionalization project was to construct a water treatment plant and interconnect the towns to create a regional water distribution and treatment system.

T&L assisted the Giles County PSA in this endeavor in the following ways:

• Assistance to the PSA in the negotiation of inter-municipal agreements with each participating locality; and
• Working with the PSA to find a new source of water for the PSA and participating localities;

A groundwater well near the New River was able to produce up to 2.0 MGD of raw water of adequate quality with microfiltration treatment. Pilot studies were performed and the microfiltration system was designed, constructed, and placed into service with a design flow of 2.0 MGD.

T&L also developed hydraulic models for the interconnection of the towns to create a regional system for Giles County. Several pressure zones were required to maintain proper pressures throughout the system, necessitating the construction of pump stations and tanks to serve these zones.

Recent studies have been undertaken by the PSA with T&L’s assistance to develop alternate sources of water. One source studied is raw water to be withdrawn from the New River, and a second is a potential mine water source.
