Volume of the <br />tank was between 9,000 and 10,000 gallons. Because pipework atop the tank prevailed me &OM <br />sealing d after sampling two weeks ago, I performed a Hach kit field test for copper. The result <br />was 0.27 mg/L , which is well under local limits for Stockton. The water's appearance was <br />undianged and meter readings indicated no sulfide or LEL problems within the tank. PH paper <br />confirmed an acceptable range of 8.0 to 9.0. I informed Ah that everything looked good and to <br />commence with pipeline and pump setup while I removed the sewedine 0%. Discharge to the <br />sewer began at 0955. The pipeline terminated at the weir box in the pretreatment area. Rate of <br />discharge was apprommately 40 Win withomt the pump, slightly higher with pump assistance.
