PINEY BAY RAW WATER INTAKE

HYDRAULIC CAPACITY OF 24-MGD
Scope Of Work $1.1 Million
Schedule Completed in 1993

Project Detail

The Piney Bay Raw Water Intake was constructed in 1992-93 as part of an $11.5 million project undertaken for Clarksville Light & Water.

The intake has a hydraulic capacity of 24-MGD and consists of a dual chamber wet well (19’ x 10’ each) with a normal water depth of 23 feet. The wet well has four intake ports at varying depths equipped with stainless steel fixed drum type screens with air backwash systems. The pumps, which have a current capacity of approximately 11-MGD, are housed in a 1,200 square foot split face block building located over the wetwell.

The building, which has room for six pumps, also contains a potassium permanganate feed system for algae and other organic substances control, a motor control center, and an air backwash system for the screens. Special design and construction procedural considerations were required to meet environmental requirements of state and federal regulatory agencies.
