April 2022 Water distribution
The District receives its water from 3 groundwater wells and an intake in the Trinity River. See schematic of the LCSD Water System below.
The water from the Trinity River is treated at the water treatment plant off Riley Mine Road and then goes into the North Tank to meet its contact time before entering the Distribution System. We have a continuous chlorine analyzer monitoring the chlorine residual as it leaves the North Tank and enters the distribution system to ensure we always have at least a 0.02 mg/L entering the system.
The groundwater is treated with chlorine before it enters the distribution system.
Daily, our operators check for a chlorine residual at 5 different locations throughout the distribution system to ensure we maintain a chlorine residual. At the very end of the distribution system, we typically have a chlorine residual of 0.3 mg/L. We also check the South Tank chlorine residual daily as that is the tank the groundwater wells typically pump into if there is no demand on the system. On average, the South Tank has a chlorine residual of 0.3 mg/L.
