Improvement District No. 4 Henry C. Garnett Purification Plant - Oswell Tank Redesign
Document Type
NOE - Notice of Exemption
Document Description
The Kern County Water Agency's Improvement District No. 4 (ID4), 6.8 million gallon domestic water Oswell Tank has a common water inlet/outlet design. This results in long detention times and creates the need to rechlorinate the drinking water to maintain a detectable residual in the system. The disinfection by-product monitoring data shows that water leaving the Oswell Tank have elevated levels of total Disinfection Byproduct Rule requirements when they become effective in May of 2002. To remedy this situation, ID4 proposes to redesign and reconstruct the common water inlet/outlet system to a flow through design. This will ensure a significant reduction in the time water resides in the tank and allow for the continued displacement of fresh water within the tank. This will benefit the citizens of ID4 within the greater metropolitan area of Bakersfield whose supply of water depends on this facility.
