3.0 Preparation

The number and specific order in which each component of the System are to be assembled must be determined ahead of time. The depths of the desired monitoring zones and layers of backfill (where applicable) must be determined in advance of the installation. The design log will serve as a reference during the install. Ensure that an 'as built' installation log is maintained. See Appendix I for an example of a "Waterloo System Installation Log".



In designing the layout, it is preferable to allow one to two feet of clearance above the bottom of the borehole. Problems of measurement inaccuracy, sloughing during installation, and other unforeseen events which may prevent well completion are thus minimized.


Before the install date, reconfirm that the borehole is still open to its target depth. Once the Waterloo System received, make sure that the shipment looks complete and that nothing appears damaged. Contact Solinst immediately to resolve any issues before proceeding with the install.



If the depth to water is greater than 100 ft. (30 m) below ground surface, lower the system with the support cable and drilling rig.


If a Solinst Trainer is requested, the training will be completed in its entirety, prior to starting the installation. See Appendix IV for the Terms and Conditions of training.

The System weighs about 1 lbs/ft., which doesn't include the weight of the Packers. Therefore, at least two physically strong field assistants will be needed to lower the System by hand. If the depth to water is more than 100 ft. (30 m) below ground surface, then a hoisting winch (drilling rig) will be needed to assist with holding and lowering the System via an optional support cable.



Be sure to document the position and placement of each downhole component, during the installation. An 'as built' installation log is a crucial part of knowing where each monitoring zone is placed.
