Why you need a technical liquid tank
For private houses the tank can collect rainwater from the roof for watering lawns and gardens, washing paths and cars, and other utility needs.
For businesses the tanks are used to collect process wastewater, store technical water, reuse treated water after local treatment plants, and serve as buffer vessels in production processes.
Using technical liquid tanks reduces drinking water consumption, eases the load on the mains network and cuts water supply costs.
Recommended volumes: private houses — 4–10 m³; hotels, holiday resorts and commercial sites — 10–50 m³; production facilities — from 20 m³ upwards depending on process needs.
