Check the specifications for the specific tank you plan to install.
Ensure the specific tank has been designed and constructed for underground use, if this is the purpose for which it will be used. Palmer offers the customer a selection of lining reinforcements and resins, which are specific for use below ground. Palmer was the first company in the United States to use a three dimensional woven glass fabric, termed Parabeam, in their tank fabrication.
Ensure that you know which connectors and other fittings you will need to install your tank and get these before you begin the installation.
Dig the hole to meet the size specifications relevant to your specific Palmer water tank. You might need to use a mechanical digger for large holes.
Remove any large and particularly sharp stones, as the weight of the water in the tank pushing down on such objects, can cause the tank to be damaged or punctured.
Install a liner that has been manufactured for use with a fiberglass tank in the hole you have just dug.
Remove the tank carefully from the delivery vehicle. Depending on the size of the tank, a crane incorporated on the vehicle will have to lift it from the truck to the ground.
Place ropes around the tank and use these to slowly lower the unit into the hole. Very large tanks must be lowered into the hole by a crane.
Check your fiberglass tank on a regular basis for signs of leaks and make repairs immediately, if needed.
