T Well Data Sheet Instructions(Rev. 11/99) Page 7 <br /> may be the previous year, the average of the last five years;of <br /> whatever information is readily available. This information may be <br /> found on water agency annual reports to DWR. <br /> Frequency of use Enter in hours per year. The water system is typically the only <br /> source for this information, and they may not have it. <br /> Typical pumping duration Enter in hours per day. The water system is the only source for this <br /> information,typically. It can be the average number of hours per <br /> day over the last year. <br /> PUMP <br /> Make Enter the name of the manufacturer, if known. <br /> Type Types of pump include: Centrifugal pumps (suction lift,vertical <br /> turbine, or submersible turbine);Jet pumps; Airlift pumps. <br /> Size Enter in horsepower(hp). Enter only the value,not the units. <br /> Capacity The pumping capacity to be used is the maximum rate the welt can <br /> be pumped, in gallons per minute. If the pumping capacity is not <br /> known it should be estimated based on historical records, local <br /> knowledge or by using the value for a system or source of similar <br /> size. However, if it is likely that the pumping rate is low(less than <br /> 15 to 20 gpm), it is not necessary to estimate the pumping capacity. <br /> If the pumping capacity is not known, the field can be left blank or <br /> enter"Unknown". See additional notes at the end of this guidance. <br /> Depth to suction intake Enter as feet below ground surface. This is the depth of the intake <br /> for the pump. This is not recorded on a well log,and is not always <br /> known by the water system unless the well was recently <br /> constructed. <br /> Lubrication type Is oil or water used as the lubricant for the pump? <br /> Type of power Type of power used to supply the pump on a regular basis(typically <br /> electric, but can be a diesel generator, or other power source). <br /> Auxiliary power available? Is a standby generator available, or some other type of backup <br /> power supply? <br /> Operation controlled by: What controls the pump to turn on and off? Typically automatic, <br /> not manual. The pump may be controlled by the level in a storage <br /> tank, or pressure within the distribution system or a pressure tank, <br /> or other system controls) <br /> Pump to waste capability? Can the water from the well be discharged without going into the <br /> water system? <br /> Discharges to: The well may directly discharge into a transmission line,a storage <br /> tank, the distribution system, or other part of the system. <br /> Pump Capacity <br /> The most important piece of information on the WDS for purposes of the DWSAP <br /> program is the capacity of the pump. This value is used to determine the size of the <br /> protection zones around the well and is considered in the PBE evaluation. Pumping <br /> capacity is used to estimate the volume of water that will be drawn to a well in a specified <br /> time. The pumping capacity to be used is the maximum rate the well can be pumped, in <br /> gallons per minute. <br /> The approximate pumping capacity of the well should be known by the water system. If <br /> the pumping capacity is not known it should be estimated based on historical records, <br />
