Rainwater Harvesting

Harvest Nature's Most Precious Resource

Reduce utility costs and your environmental footprint

Why Harvest

Water is arguably our most precious natural resource and has been and continues to be an integral part of the development of human society. Many of us are misinformed about the availability of water and often take this limited resource for granted. Water usage is necessary for a vast number of societal applications from agriculture, drinking water, and sanitation to name a few. It is well known that we are wasting billions of litres every day, from food production to recreation purposes. With increasing water restrictions, higher utility costs, and stormwater requirements becoming more important than ever for Ontario residents, rainwater harvesting can provide a solution for this watershed moment.

The Waterloo Process

Harnessing Nature’s Most Precious Resource

Rainwater harvesting is the practice of collecting precipitation from a rooftop or other surfaces, for the purpose of water re-use. Typically, rainwater is collected from rooftops, conveyed to a storage tank, and filtered before it is used as a non-potable source of water inside or outside the building.

Waterloo Biofilter Systems is the Ontario distributor of Graf rainwater harvesting components. These high quality components are pre-packaged into a complete, ready to install rainwater harvesting solution.

Captured rainwater goes through four separate filtering steps before reaching its intended use. If the water level in the storage tank is low the system can be equipped to automatically supplement rainwater use with municipal or well water thereby ensuring adequate supply. Waterloo Biofilter has many different options to fit the desired application including downspout filters, first flush diverters, storage tanks, in-tank filters, pump and controls.

These low maintenance solutions are ideal to reduce environmental impact. Waterloo also has solutions to fit commercial or municipal rainwater harvesting applications.
