Designed for simplicity

The pump inertia Waterra was designed from the outset to meet four goals: simplicity, performance and quality's sampling in an affordable device for all, regardless of income. By eliminating too complex and technical parts such as tanks, pistons and submersible motor, one can produce an inexpensive pump and easy to use. The final product consists of a foot valve and a plastic hose which oscillates up and down in a well producing a stream of water.


  • Waterra the pump consists of a valve in plastic or stainless steel, screwed onto a rigid HDPE pipe, which is immersed in water the piezometer.
  • Applying a vertical translational movement (up / down) to the pipe, causes the opening and closing of the valve lift and, by inertia, of the water to the surface. Over the beating frequency, the higher the bit important.
  • Waterra the pump can be manually operated (20-25 meters), or electrically with the motor Hydrolift II (50 to 60 meters)
  • Ease of use : The simplicity of the pump design makes them easy to use without the need for an instruction manual or special training to use the machine to its full capacity. This simplicity reduces the risk of breakage, wear and reduces frustration for the user. Simplicity field makes effective unit.
  • Versatility : The Waterra system reduces the time and expense using the same pump for developments well and for sampling.
  • The development wells : The development of wells is one of the most critical tasks of groundwater analysis practices. These typical goals are: the removal of sediment filter and the reduction of the turbidity of the sample.


  • Reduced cost for monitoring a network of piezometers.
  • No risk of cross contamination since each piezometer rest. provided with its valve and the pipe length.
  • Materials in contact with water are chemically inert (HDPE).
  • Excellent integrity of samples taken.
  • Reduced maintenance.
  • Establishment and decline very fast hardware.

Scope of performance

Waterra four stretches of pumping to ensure that all small or large diameter wells and deep wells can be sampled effectively. The four areas are the following: micro current, low current, standard current and high current The four systems fonctinnent with the principle of inertia and differ only in size.

With pumping engine Hydrolift II

Pumping with electric motor Hydrolift II.
Using the Hydrolift II engine allows the system to offer Waterra very good pumping performance.
The Hydrolift II motor fits all types and diameters piezometer, it moves very easily requiring no special installation.

Features and Specifications

The throughput level : The level of flow differs from one well to the other depending on the depth, diameter, of the recovery process and the pumping system chosen. The flow rates of 0.3 gpm can be supported with the micro flow system and up to 4.0 gpm with the high throughput system.

The lifting capacity : Waterra has an operational flow system to depths of over 100 feet and to depths up to 230 feet under certain conditions. The automated pumping system Waterra simplifies the deep narrow well sampling allowing the sampler to perform other tasks while the pumps are running.

The extent and the diameter of wells : Small size wells 0.5 'ID to large-sized 6''ID are easily accessible with Waterra pumping line. It increases the pumping system inertia and achieve the greatest possible extent, more than any other pump on the market.
