How a Waterra Pump Works

How to Sample Drive Point Piezometers is easily solved using the Waterra Pump Micro Flow System. Drive point piezometers are established by driving a short, hollow, narrow diameter hard point into the ground. They typically have a screened interval and usually have an approximate inner diameter of 1/2 inch (13 mm). The Waterra Pump System, in particular the Micro Flow System, is frequently used in these situations because of its narrow diameter.

The Waterra Micro Flow System usually consists of:

  • an SS-10 Foot Valve
  • a length of HDPE or LDPE Micro Flow Tubing and
  • is typically hand operated

Procedure For Sampling Drive Point Piezometers With A Waterra Pump – Micro Flow System

Here’s How to Sample Drive Point Piezometers.

  • Screw the SS-10 foot valve into the Micro Flow Tubing up to the shoulder on the valve
  • Feed the tubing (valve first) down the well to the screened interval
  • Cut the tubing off about 6 feet (2 m) above the well head
  • Initiate pumping by hand by pulling the tubing up and down
  • Pump at your desired flow rate
  • Purge as your protocol determines
  • Collect your sample
