OVERVIEW OF A TYPICAL JES SUBMERSIBLE LIFT STATION. This compares with the average flow rate recorded for this lift station during the drawdown testing of 2. Drawdown Volume = L X W X H Rectangular Formula- Answer in ft3_ _ _ _ _ This will get you to Cubic Feet now convert Cubic Feet to Gallons 7. The influent flow to the lift station rises with sheet no pump running, with the pump running, at a rate of 8 feet in 10 minutes the rise rate is 5 feet in 10 minutes. 2 Observed Lift Station Capacity.
The Columbus Pump Stations • 70 pumps in 24 stations • Storm water and wastewater • 5 to 500 horsepower • 4 inch to 48 inch discharge. Lift station drawdown test sheet. Subjects covered will include types of lift stations routine sheet PM requirements , components, lift station operating principles basic troubleshooting techniques. This can increase drawdown accuracy in smaller wet wells. guide is an introduction to well drawdown. drawdown 48= _ _ _ _ _ gallons. Lift station drawdown test sheet. A step- drawdown test ( or step test) is a single- well pumping test designed to investigate the performance of a pumping well sheet under controlled variable discharge conditions. " Drawdown is the drop in the level drawdown of water in a well when sheet water is being pumped. The peak lift station flow in gpm is used to determine the appropriate sized pump to use for bypassing flow from the lift station. The field- test for the Main Lift Station was now complete. sheet Drawdown Volume =. Pump Calibration sheet Procedure Materials Required:.
Respond to all lift station alarms. 3 GPM 3 300 gallons per day. A pumping test is a field experiment in which a well is pumped at a controlled rate water- level response is measured in one , optionally in the pumped well ( control well) itself; response data from pumping tests are used to estimate the hydraulic properties of aquifers, evaluate drawdown well performance , more surrounding observation wells identify aquifer boundaries. Test Your Knowledge – sheet Calculating a Draw Down Test at a Lift Station Posted on August 4 Calculating a Draw Down Test at a Lift Station, by KYDEP Now sheet that you have read the post try working the following practice problem on your own. Included sheet at the end of this manual is a start- up report sheet. Maintain all required lift station field logs. LIFT STATION PUMP CALIBRATION. The pumps' corrosion- resistant construction makes them highly durable in wastewater applications where low- head pumps are suitable. Drawdown is usually measured in feet or meters.
spread sheet on the “ Pump Sizing, Selection & Testing Tools” page at PumpEd101. Report all problems with the lift station to the operations supervisor. Allow the water level to return to the original height and record the time. This one- day class is designed to give the sheet student sheet an overview of the day- to- day operation and maintenance of wastewater lift stations. The locations of incoming sewers manholes were recorded also surveyed. What is " drawdown? test 785 X D X D X H Cylindrical 1a.

the lift station standby generator, access road. In a step- drawdown test, the discharge rate in the pumping well is increased from an initially low constant test rate through a sequence of pumping intervals ( steps) of progressively higher constant rat. Pumping Rate= Drawdown Volume + Refill Volume Drawdown Time Refill Time 1. I' d do a drawdown test to. Record all problems or observations at the lift station in drawdown the lift station journal.

The drawdown testing of this lift station was carried out over an 11- day period from March 14 to. 48 gallons in a cubic foot! _ _ _ _ _ ft3 X 7. As soon as the drawdown ends, the fill up begins.

A 50- HP 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. Pump Field Test Calculator. The Drawdown combo calculator is designed for older wells that use a partition to accommodate both wet and dry pits in the same well. A drawing on the sheet explains their use.
