A good, lightproof and vermin proof cover is one of the most
important requirements for a safe water system. Our covers are that
and much more. They can be used as a foundation or lanai. Several
people have put their spas on top of the tanks. We provide a manhole
for access to the tank for cleaning. The manhole itself has a raised
lip and when covered with the provided ferrocement manhole cover,
nothing can blow in or wash in to your tank.
