Rainwater Harvesting Systems

We recognise a rainwater system to be a combination of quality guaranteed products, tried and tested in combination, that will, with proven high efficiency and minimal maintenance, collect, process and pump rainwater to all needed areas around the building – enhancing the rainwater experience – not adding to the homeowners problems.

INTEWA systems are designed to be easily maintained and to provide the owner with a long, effective service life.
