A district buys drilling, pump work and rehabilitation from specialists, and the specialists keep the best record of what they did — in their own files. The district gets an invoice, a one-page report and the well back. Two contractor changes later, nobody knows what pump is in the hole. The fix is a deliverables list in every contract, and a place to put the deliverables.
From the drilling contractor
- The DWR well completion report and the full lithologic log
- Geophysical logs, sieve analyses and the filter-pack gradation
- Casing and screen schedule with materials, slot size and intervals
- Development log, step-drawdown test and constant-rate test
- Post-construction video survey
- Plumbness and alignment results
From the pump contractor
- Pump make, model, bowl size, stage count, impeller trim and serial numbers
- The manufacturer’s certified curve for the pump as built
- Motor nameplate: make, horsepower, voltage, speed, service factor, efficiency class
- Column, shaft and tube specifications and the pump setting depth
- VFD make, model, minimum and maximum frequency, skip bands
- A wire-to-water efficiency test after installation — the baseline everything later is compared with
From the rehabilitation contractor
- Pre-treatment video survey and step test at a stated rate
- The chemicals used, with quantities and contact times; the mechanical methods and passes
- Development pumping log and disposal record
- Post-treatment video and step test at the same rate
- An itemized cost breakdown — mobilization, chemicals, mechanical, development, testing, disposal
Manufacturers’ data belongs in the record
Districts run equipment from many makers, and the record should not care which. Vertical turbine and submersible pumps from Xylem’s Goulds Water Technology, Grundfos and Peerless, Flowserve (including the Byron Jackson line), National Pump Company, Layne/Verti-Line, Simflo and American-Marsh; motors from Nidec’s U.S. Motors, WEG, ABB/Baldor, Franklin Electric and Hitachi; drives from ABB, Danfoss, Yaskawa, Rockwell Allen-Bradley, Schneider and Siemens; screens from Johnson Screens, Roscoe Moss and Delta. Each supplies a curve, a nameplate or a specification sheet, and each is a document a well record should hold and read. Waterwell IQ™ takes the design data from any manufacturer’s curve — BEP, design head, shut-off head, stages, speed — and draws the pump’s curve with the well’s tests on it.
Make filing the easy path
Contractors will provide all of this when it is asked for at bid time and when filing it is easier than emailing PDFs. Waterwell IQ gives drillers and pump servicers a free, permanent account: they file the test or report once, against the district’s well, in the district’s template; the district reviews and approves; the contractor keeps its own record of every well it has touched. The report that used to live in a truck becomes the district’s baseline.
