Hydrasleeve from Waterra

No-purge sampler for groundwater monitoring wells and sampling programs

 A HydraSleeve is a new way to collect discrete interval water samples. With no need to purge or dispose of purge water, this groundwater sampler reduces your costs by saving time.

  • Long or short term groundwater monitoring
  • Samples low-yield wells
  • Determines dissolved contaminant fraction
  • Samples crooked or constricted wells
  • Vertically defines contaminant concentrations or composites sampler from 10′ screen interval

What is a HydraSleeve?

Unlike any other groundwater sampler, the HydraSleeve instantaneously “cores” a whole water sample from a defined vertical and horizontal interval (usually within the well screen). HydraSleeve samples do not blend fluid from different vertical zones or pull water in from outside the well screen, but instead sample via ambient and/or diffusive flow of groundwater through the well screen.

The sample is collected at in-situ pressure without purging and with very little down well disturbance, preventing turbidity, aeration or oxidation of sensitive parameters. Samples collected with the HydraSleeve correlate well to other sampling methods.

HydraSleeve samplers are inexpensive, disposable and very quick and easy to use, resulting in significant savings on capital equipment and operating costs when compared to other sampling equipment.

Let’s get started...

From the product layout below, choose a 2 inch or 4 inch Hydrasleeve based on well size
Then choose based on whether you want an armoured (tougher) HydraSleeve
And finally choose the volume of sample you would like

Waterra Words of Wisdom

  • HydraSleeves require Weights (Top and Bottom) to deploy properly and the recommended ones are listed on the table below.
  • Plan ahead. HydraSleeves require equilibration time so don’t think you can just run out to the field and collect a sample.
  • Waterra Groundwater Filters can be used with HydaSleeves as outlined below.


HydraSleeve is suitable for both short and long term groundwater sampling programs and is especially useful in narrow, constricted or damaged wells. HydraSleeve samples can be filtered using Waterra Groundwater Filters. Click here to see how.

Cost savings of HydraSleeve sampling make it the option of choice for monitoring UST leaks, dry cleaning plants and other small scale point-source contaminant sites. It can even be used for special challenges such as in-well vertical profiling of multi-layered contaminant concentrations.

HydraSleeves are...


  • No training or special tools required – simply “pop & squeeze” open the top and attach your line and the re-useable weight
  • Small and convenient
  • Simple shipping


  • No purge water disposal
  • No expensive equipment
  • Disposable


  • Collect samples in less than 15 minutes
  • Cuts total field time by half or more
  • No decontamination between wells


  • Sample for ALL compounds
  • Large sample volume
  • Best sampler for slow recharge wells
  • Conservative results comparable to conventional methods
  • Repeatable sampling method
  • Lower turbidity than purge and sample
  • Slim cross section minimizes disturbance
  • can be collected at in-situ pressure
  • precise vertical and horizontal interval – no blending
  • little or no aeration, agitation, degassing or displacement
  • samples can be analyzed for all parameters
  • samples a discrete, instantaneous “core” of water
