* Ensure the perforated section of the well is located within the internal water storage reservoir or layer only, and that it extends to the bottom elevation of the practice at a minimum.

* Design and install the well so that surface water will not affect water level readings. A standard monitoring well casing and cap to protect, secure and provide access to the well should also be included.

* Ensure there is a solid cap on the bottom of the well to provide a small water reservoir (e.g., 100 mm deep) to keep water level sensor submerged during dry conditions. This helps with checking calibration of the sensor as well.
