Where a site needs substantial storage without giving up usable ground, the 800 gallon underground water storage tank provides a larger reserve below the surface. Al Bassam manufactures this underground water tank in High-Density Polyethylene and designs it specifically for buried installation, so the capacity can increase while the visible impact on the site remains at the access cover. The 800 gallon body is moulded in one piece and built with 3 functional high-density polyethylene layers. These combine a UV-stabilised exterior, an extra-thick insulation layer that helps reduce heat transmission, and a food-grade inner surface for potable-water storage. Wide vertical ribs reinforce the shell along its height, and a threaded cover closes the access point against surrounding foreign material when correctly fitted.
Larger capacities usually compete with the space a site can spare, and underground placement removes that constraint. The 800 gallon volume is held below grade while only the access cover remains at surface level, supported by a layered wall and a reinforced one-piece body. The features below describe the construction behind that arrangement.

Core Product Benefits
Suitable For
An 800 gallon capacity suits large villas, residential buildings and commercial premises with sustained daily demand, and projects where buried storage helps preserve the surface for access, landscaping or other site uses. Facility use in schools and similar sites remains subject to project, hygiene and installation requirements.
