System Flexibility

Waterloo System Flexibility

The Waterloo Multilevel System is flexible to meet your design criteria. Each Waterloo System is customized to suit unique monitoring needs, and subsurface site conditions:

Packers and ports are installed precisely to monitor each isolated, discrete zone of interest, eliminating any crosscontamination across zones.


Overburden Applications

Waterloo Multilevel Systems can be used to monitor multiple zones within unconsolidated formations, as well as in bedrock.

There are three methods of Waterloo System installation:


Installation within Wellscreen/Casing

A permanent 3" or 4" casing and screen string can be installed by a drilling contractor using typical sand and bentonite placement methods. Then a Waterloo System can be installed within the screen and casing string with ports and permanent packers.


Borehole Size Considerations

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

Dedicated Pumps and Open Tubes 6
Dedicated Pumps and Transducers 8
Dedicated Pumps Only 12
Open Tubes Only (varies with tube size) 15
Dedicated Pressure Transducers Only 24


Number of Monitoring Zones Per Hole

The maximum number of monitoring zones for a Waterloo 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.
