System Flexibility

The Waterloo System is extremely flexible to your design criteria. Each System is customized to suit monitoring needs, site conditions and budget constraints:

Removable or permanent system

Bedrock or overburden applications for groundwater or vadose zone monitoring

Packers and ports can be accurately placed to monitor each zone of interest.

 

Multi-Purge Manifold with Transducers
and Dedicated Pumps for four zone monitoring 

Materials

For particular applications specific materials may be chosen. These may include stainless steel casing and packer bodies, and stainless steel, nylon or Teflon® tubing.

Borehole Size

Waterloo or removable packers are designed for use in 3"- 4” boreholes (75 - 100 mm). Systems can be installed in larger boreholes using:

Placement of sand and bentonite to isolate parts around a Waterloo casing string with no packers.

3-4” screen and casing, installed within a larger hole, completed by installing a Waterloo System with packers.

Number of Monitoring Zones / Hole

The maximum number of monitoring zones for a System is determined by the number of tubes and/or cables that will fit inside the casing string. This number is dependent on the monitoring options chosen. Systems can be designed to monitor from 2 to as many as 24 zones.
