Water Flute
Multilevel Groundwater Monitoring System

Model 405

A trusted technology for high quality multilevel groundwater monitoring since 1996, the Water Flute is a depth-discrete multilevel groundwater monitoring and head measurement system for use in overburden and bedrock groundwater assessments.

The Water Flute system uses a flexible liner to seal the interior of a borehole, except for determined sampling intervals. The liner can contain fifteen or more monitoring ports based on the borehole diameter.

The liner is instrumented with a gas driven pumping system with a sampling port at each defined interval. High quality groundwater samples are collected directly from the formation, as the Water Flute is fully dilated against the borehole wall. This ensures the borehole does not contain mixed formation water. Manual water level measurements can also be made at each monitoring port, or dedicated transducers can be installed downhole. The Water Flute can be installed in boreholes ranging from 4″ to 19″+ (10 cm to 48 cm +) in diameter. Systems have successfully been installed to 425 m (1400 ft). Water Flute systems have been installed in 48 states in the U.S., and many other countries, for almost 20 years.

Advantages of the Water Flute

  • Over 15 depth-discrete zones in a single borehole
  • Reduces costs and field time while delivering high resolution subsurface data
  • Simultaneous purging and sampling of all zones increases efficiency
  • Provides a continuous seal of a borehole and prevents migration of formation fluids
  • Borehole not left open to allow cross contamination
  • No sealing grouts or packers needed between zones
  • Easy to locate ports and seals exactly where desired
  • Installs quickly in stable open boreholes or screened and cased wells
  • All system components are compatible with VOC and PFC sampling
  • Liner is completely heat welded without the use of any glues.
  • Custom fabricated to meet demands of different diameters and materials for many applications
  • Propagates through tortuous passages of varying diameters inaccessible to rigid piping or push rods
  • Warrantied and fully removable
