We understand that every project has unique requirements and limited space. Haplast can provide large water storage tanks customized to your needs.

100% sealed water reservoir

With our water reservoirs, you get a leak-free solution that lasts. We install tight, insulated lids with locks and all pipe penetrations are fully welded.

Safe drinking water

Haplast water storage tanks are ideal for buffering drinking water. The tanks are supplied with virgin PE in the inner layer and we install ventilation pipes with Hepa filters. PE does not react chemically with water and does not corrode. Smooth and bright interior surfaces simplify cleaning and inspection.

Durable solutions

The tanks are made of PE based on recognized KRAHTM technology. PE is a flexible and strong material that can withstand high internal and external preassre for more than 100 years without leaking, cracking, breaking or shifting.

Customization

Our water reservoirs are delivered as fully assembled lengths or sections of up to 24 meters - limited only by the permitted transport length. If larger reservoirs are required, we can supply modules of 6-24 meters that are easily joined together at the construction site. It is also possible to connect the reservoirs in series to take advantage of limited space or challenging angles.

If required, we can supply water reservoirs with pump chambers and lockable lids with safety grids.

Quick and easy installation

Haplast delivers complete solutions, fully assembled according to customer specifications. Our PE tanks are highly impact-resistant and provide strong structures that allow local soil to be used as backfill in accordance with the installation instructions. The tanks have double walls that do not require insulation when sufficiently buried. Low weight makes the tanks easy to move and simplifies installation in trenches.
