High Flow Groundwater Sampling Pump

Waterra High Flow Pump for Sampling

High Flow Groundwater Pumps were developed by Waterra for deep wells ( up to 300 feet) and as a terrific well development system. The bigger tubing lends a stiffness that minimizes stretch in deep wells as well as permits higher flow rates.

This system is typically used in 2 and 4 inch monitoring wells.  Waterra Pumps are often dedicated to wells due to their low cost and to avoid cross-contamination or de-conning issues.

Waterra Pump System - High Flow for groundwater monitoring wells

2 and 4 inch monitoring wells

Max Flow: 
4 gpm = 15 lpm
Max Lift:
300 feet = 90 m

Here's How a Waterra High Flow Pump Works

  1. A D-32 (Delrin) or SS 32  (Stainless Steel) Waterra Foot Valve is attached the bottom end of a length of HDPE Waterra Tubing.
  2. The Foot Valve – Tubing combo is inserted into the well, Foot Valve first, until the valve is submerged beneath the water table to the desired pumping depth.
  3. The tubing is then oscillated (pulled up and then pushed down) over a short vertical range (about 1 foot (30 cm) of motion by a Hydrolift Electric Actuator or a Power Pack gasoline driven actuator.
  4. Water builds up in the oscillating tubing until it discharges at surface.

Waterra Pump System - High Flow Foot Valves for groundwater monitoring wells

The High Flow System is our most robust system and is used around the globe to sample and develop 2 and 4 inch monitoring wells.

The D-32 (Delrin) and SS-32 Stainless Steel Foot Valves can deliver a sample from as deep as 300 feet (90 m). At lesser depths flow rates are up to 4 gallon per minute (15 lpm).

VOC Sampling with the High Flow System

Waterra Pump Lever Arm and VOC sampling
  • Complete the applicable pre-sampling protocol whether it be the classic “purge three well volumes” or “pump until stability of well water parameters is achieved” or other protocol using a Waterra Pump system.
  • Keep pumping but insert the VOC sampling tube up into the Waterra Tubing as illustrated above.
  • Position the VOC tubing so that there is no cascading of water in the VOC tube.
  • Direct the flow into your sample vessel.
