A poly plastic water tank is your best solution when buying new water storage tanks

Durable - A Loomis poly water tank is made to last! Our water storage tanks put into service over 20 years ago are still performing perfectly today. The UV stabilized polyethylene resin used to manufacture a Loomis plastic water tank is formulated to protect our water storage tanks from the harmful effects of the sun.

Easy to handle and install lightweight plastic water storage tanks - Loomis understands that often water storage tanks must be placed in a location not readily accessible.

A plastic water tank is extremely portable, and choosing a Loomis poly water tank makes the job of installation much simpler and easier. Most water tank sizes can be transported using a standard sized pickup or a lightweight trailer. Once at the site, a poly water tank can be manually maneuvered, rolled and lifted into position - expensive, heavy equipment is usually not required to install a poly water storage tank.

A Loomis poly water tank can be set on native soil or a simple sand pad -- no expensive concrete or gravel pad needed!

Maintenance Free Water Storage Tanks - A Loomis plastic water tank requires virtually zero maintenance. Typically offered in dark green or black opaque colors -- which helps prevent algae growth -- a poly water tank almost never needs cleaning.

In the unlikely event of damage to a poly water tank, repair is easy using nothing more than poly cord and a heat gun!
