Think Rainwater Harvesting System Instead of Traditional Water Management

Construction seals off land, making it impermeable, with less rain water getting back into our aquifers. As we consider construction plans, we want to think about low impact development (LID), and as many are now doing, adopt LID in place of traditional water management systems. LID for rainwater harvesting can be practiced in many ways – passive – via a simple rain garden, green roof, and permeable pavements – all of which passively assist in reducing rainwater runoff by redirecting it.

In an active system, you’d divert rainwater from a roof to a storage tank to be reused – possibly for laundry, toilet facilities or even drinking water. This has commercial and residential application.

Some small systems are easy for do it yourself projects, but if you’re looking to builda complex system, you should always seek the services of an accredited professional.
