Service

To the best of its ability and in consideration of the existing source, the District will supply water at each customer’s service connection dependably and safely, in adequate quantities to meet the reasonable needs and requirements of the customer.

 The District will attempt to maintain flowing pressures at the District’s distribution mains under normal conditions of at least 20 psi, except that during periods of peak hourly demands, the static pressure will not be less than 15 psi, and during periods of minimum hourly demands the static pressure will not exceed 100 psi.

The District will provide potable water that meets the standards of the United States Public Health Service (USEPA) for potable water as determined by the California State Department of Public Health.

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.
