Rain Harvesting
Resource from heaven
Recovery and recycling of rainwater has a direct contribution to solve the problems of waste, scarcity and rising cost of water supply.
In the private sector about 50% of the daily requirement of water may be replaced with rainwater.

Anyone can put a downspout into the top of a cistern and call it a rainwater collection system. We believe a rainwater collection system is defined by the details. We provide systems that are designed with function, maintenance, and aesthetics in mind. Rainwater collection systems should not be eyesores.

Collection Plant storage and disposal of rainwater
Important parameters for plant design are:
- Amount of surface to collect rainwater
- Surface runoff coefficient;
- rainfall (obtainable from specialist publications);
- System sizing
A collection and run-off rainwater system is basically composed by 5 subsystems:
- Collection
- Pretreatment
- Storage& Treatment
- Overflow dispersion
- Distribution
