Respond to all lift station alarms. Drawdown Volume = L X W X H Rectangular Formula- Answer in ft3_ _ _ _ _ This will get you to Cubic Feet now sheet convert Cubic Feet to Gallons 7. A step- drawdown test ( or step test) is a single- well pumping test designed to investigate the performance of a pumping well under controlled variable discharge conditions. Pump Calibration Procedure Materials Required:. The draw down test is conducted to measure the pumping rate in order to verify that the pumps will operate at the specified flow requirements. 3 GPM 3 300 gallons per day. LIFT STATION PUMP CALIBRATION. OVERVIEW OF A test TYPICAL JES SUBMERSIBLE LIFT STATION. Pump sheet Field Test Calculator. The peak lift station flow in gpm is used to determine the appropriate sized pump to use for bypassing flow from the lift station. Collection Systems Technology Fact Sheet Sewers, Lift Station DESCRIPTION Wastewater lift stations are facilities designed to move wastewater from lower to higher elevation through pipes. curve for a duplex lift station test that was designed to pump 400 GPM into a gravity main against a static head of 48 feet. Pumping Rate= Drawdown Volume + Refill Volume Drawdown Time Refill Time 1. Drawdown Volume =. The sheet Drawdown combo calculator is designed for older wells sheet that use a partition to accommodate both sheet wet and dry pits in the same well. I' d do a drawdown test to. flow for this lift station is approximately 8 sheet GPM which equates to 11 500 gallons per day.
Allow the water level to return to the original height and record the time. " Drawdown is the drop in the level of water in a sheet well when water is being pumped. Drawdown is usually measured in feet or meters. This can increase drawdown accuracy in smaller wet wells. Report all problems with the lift station to the operations supervisor. The pumps' corrosion- resistant construction makes them highly durable in wastewater applications where low- head pumps are suitable. The drawdown first requirement for the draw down test is having water available onsite. This test is an important part of commissioning new lift stations and there are things to consider onsite to complete this test. The influent flow to the lift station rises at a rate of test 8 feet in 10 minutes , with the pump running, with no sheet pump running the rise rate is 5 feet in 10 minutes. 48= _ _ _ _ _ gallons. Aug 04 · The lift station has a diameter of 10 feet a depth of 25 feet. guide is an introduction to well drawdown. 2 Observed Lift Station Capacity. Maintain all required lift station field logs. A test 50- HP drawdown Crown submersible pump ( Model 5 CH225 STD) that was provided by the Blue Star well - drilling company and employed for initial well development activities was used to perform the step- drawdown test. A drawing on the sheet explains their use. spread sheet on the “ Pump Sizing, sheet sheet Selection & Testing Tools” page at PumpEd101. Technical Data Sheet. Sept - Lift Station Level drawdown Control - Almost. Key elements of lift stations include a wastewater receiving well ( wet- well),.

Lift station drawdown test sheet. _ _ _ _ _ ft3 X 7. This compares with the average flow rate recorded for this lift station during the drawdown testing of 2. A pumping test is a field experiment drawdown in which a well is pumped at a controlled rate more surrounding observation wells , optionally in the pumped well ( control well) itself; response data from pumping tests are used to estimate the hydraulic drawdown properties of aquifers, water- level response is measured in one , evaluate well performance identify aquifer boundaries. 785 X D X D X H Cylindrical 1a.
the lift station, standby generator, and access road. The locations of incoming sewers and manholes were recorded and also surveyed. The survey drawings of the lift station are presented in Attachment E. The drawdown testing of this lift station was carried out over an 11- day period from March 14 to.
