A <br /> f ' <br /> The Nest Water System <br /> Page 2 <br /> contiguous with the annular seal. The seal shall be graded to allow for drainage away from the <br /> well casing in all directions. The seal shall extend two feet in all directions from the well casing. <br /> The well casing shall extend minimum of an inch above the pedestal. The well and <br /> appurtenances shall be located in a locked enclosure to exclude access by unauthorized persons. <br /> (per Water Well Standards State of California Bulletin 74-81) <br /> The following issues are not conditions of the TNWS water permit but are concerns of EHD that should <br /> be considered. <br /> 1. EHD would encourage TNWS to incorporate a flow meter on the well. It can be a useful tool in <br /> the overall water-monitoring program. It is a helpful tool to determine periods of high demands <br /> that are acceptable and non-acceptable(leak detection). <br /> 2. EHD strongly encourages TNWS to secure the well site with fencing in a manner that will <br /> provide staff s access for maintenance and operation. <br /> 3. EHD strongly encourages water line(s)for domestic use (i.e.hand washing,toilets, showers, <br /> break rooms, drinking faucets, food preparation sinks, emergency wash sinks/showers and the <br /> like)be separated at the well from the water line(s)that will supply industrial,irrigation,or fire <br /> suppression uses. An appropriate back-flow prevention assembly shall be installed on the non- <br /> domestic use water line(s) <br /> For final approval for TNWS to place the system into service an inspection of the facility's distribution <br /> system and new water source by EHD must be arranged. Call Adrienne Ellsaesser at(209)468-0343 or <br /> Willy Ng at(209)468-3448 to schedule an inspection. <br /> Please be aware that you will be billed at a rate o $89 per hour for any further enforcement activity <br /> required. <br /> Donna Heran,REHS,Director <br /> Environmental Health Department <br /> Adrienne Ellsaesser,Lead Senior REHS Margar Lagorio, S <br /> Small Public Water System Program,Unit IV Unit IV, Supervisor <br />
