I , <br /> Kent W Raverty Trust Water System <br /> Page 3. <br /> e. A surface cement pad poured shall be at least two feet in all directions from the <br /> casing, that slopes away from the casing in all directions, be at least four inches <br /> thick, and be poured contiguous with the annular seal. <br /> f. A totalizing flow meter shall be installed down stream of each well prior to the <br /> entry point to the distribution system. The total monthly water production shall be <br /> recorded and the records made available for review by the EHD. <br /> g. The well, pressure tank, treatment system, and components of the water system <br /> shall be constructed with NSF approved components and shall be secured from <br /> unauthorized access but are readily available to staff for maintenance, removal, <br /> and operation of the system. <br /> h. The well shall be equipped with fittings and electrical connections to enable <br /> chlorination facilities to be readily installed for emergency disinfections. <br /> I i. A waste discharge line that is protected against backflow is to be installed so the <br /> well water can be pumped to waste. <br /> 3. Complete the enclosed Sample Siting Plan that indicates the locations for the specified <br /> certified laboratory to collect the monthly Routine and Repeat bacteriological samples <br /> from the water system. Contact the EHD for assistance with this plan. <br /> 4. Provide data that demonstrates the source can adequately provide the water system's <br /> Maximum Day Demand (MDD) and Peak Hourly Demand requirements forug_ality and <br /> ug antity of water according to the California Code of Regulations Water Works <br /> Standards (pump tests, meter readings, capacity tests, fixture units, water studies, etc.). <br /> 5. Submit the driller's well log, manufacturer's specification sheets for the well pump <br /> including the pump curve data sheet, and storage tanks, along with a technical report as <br /> required by the Health and Safety (H&S) Code, Section 116530 (See enclosure for <br /> technical report requirements). <br /> 6. An appropriate back-flow prevention assembly shall be installed on the non-domestic <br /> use water line(s) to prevent cross connections between the potable water supply and <br /> hazardous chemicals or non-potable water sources (such as irrigation lines, power <br /> washers, boilers, booster pumps, chemical injection points, retention ponds, sewer <br /> systems, and like sources of contaminants). All testable back-flow devices shall be <br /> tested by a certified tester upon installation, upon being repaired, and once each year. <br /> The test reports shall be made available for review by the EHD. <br /> The EHD strongly encourages that water line(s) for domestic use (i.e. hand washing, <br /> toilets, showers, break rooms, drinking faucets, food preparation sinks, emergency wash <br /> sinks/showers and the like) be separated at the well from the water line(s) that supply <br /> water for industrial, irrigation or fire suppression uses. This separation will reduce the <br /> number of backflow devices that must be installed to prevent cross connections between <br /> the potable water supply and non-potable water sources. <br /> The use of low flow toilets and low water use equipment is recommended as a <br /> conservation measure and to reduce the load on the existing septic systems and the <br /> MDD of the water system. <br /> a <br />
