Rainwater harvesting system

[Richard]

Hiya,

I'v been told I am wiring a rainwater harvesting system on tuesday, and i'v not done one yet. Just wondering whats involved... I imagine a pump, level sensors, valves?

Thanks in advance

depends on what you are harvesting the rainwater for. i assume that it will be stored in a tank,so you will have some kind of pump, (sump pump, inline pump ect) some kind of control to tell pump when to pump water, and maybe a second pump for overflow (preferably use gravity overflow into drains).
Ive only ever used rainwater for irrigation, and it was a simple system to install, but i am used to pumps and their control systems.
