Rainwater Harvesting

Harness the rain

A ReWater system can be engineered to use harvested rain as a supplemental water supply for a standard ReWater greywater irrigation system and to provide water to clean ReWater’s greywater filter. That supply source can also be engineered to back itself up with pressurized fresh water in case it runs out of stored rain, thereby assuring you a permanent supply of irrigation water.

Each of those steps is different on every project, and every system is somewhat different than the next for various geographical, topographical, hydrological, irrigational, and/or horticultural reasons.

Properly considering each step takes time. If you skimp on a step, you could end up with a system that doesn’t work well, or only some of the time, or not at all. No matter what type of system you want, ReWater can be retained to help you design and build one that does everything right.

It’s a more complex system

Compared to a standard greywater irrigation system, rain harvesting systems cost a lot in engineering, storage, pre-filters, pumps and other appurtenances, thus their cost per gallon is much higher than with greywater. This is because unlike with greywater, you receive lots of rain when you don’t need it so it must be stored for later use.

However, such systems can help you satisfy your run-off prevention mandate, making the additional costs worthwhile.

ReWater offers consulting services by contract for such projects.

Go LEED Platinum

The Leaders in Energy and Environmental Design (LEED) point program recognizes the value of greywater and gives up to three points for various aspects of ReWater’s standard greywater irrigation system.

LEED’s rating system also recognizes the value of rain harvesting’s reuse and run-off pollution prevention values and provides even more points for that type of system, up to 12 total. You can’t get any greener.

Compared to a similarly priced solar unit that will net you only 3 LEED points, it’s a bargain!
