Plan for the future today. It makes sense and cents.
Capturing and using rainwater to contribute to the water demand on a commercial building is an innovative way to reduce both costs and the impact of the building on the environment.
Water conservation is a common consideration when planning to build on a commercial scale. With water saving fixtures, waterless urinals, dual flush toilets and drip irrigation, rainwater harvesting makes sense and adds sustainability to a building. Commercial applications typically have a high payback due to the higher volume harvesting capability of large roof surfaces and the demand by commercial users for water.
Benefits of Rainwater Harvesting

Its free… The only cost is for installation and use.

It relieves demand on the already stressed municipal system

Saves money on utility bills

An efficient use of a valuable resource

Deduces flooding, erosion and the flow to storm water systems

See a return on your investment …. Not an expence

Can be used to recharge groundwater

Great for laundry as rainwater is naturally soft and lessens the demand for detergents.

It reduces the contamination of surface water sediments, fertilisers and pesticides from rainwater run-off resulting in cleaner dams, rivers and oceans.

Prolongs the life span of equipment dependant of water to operate due to the absence of corrosion producing scale like hard water.

It helps achieve Green Star SA Credits.
Why harvest rainwater?
Simple.. It is sustainable.
Rainwater harvesting is one of the most promising alternatives for supplying water in the face of increasing water scarcity and escalating prices and demand. The pressures of water supplies, greater environmental impact associated with new projects as well as deteriorating water quality in dams and reservoirs already constructed constrain the ability of communities to meet the demands for fresh water fro traditional sources, rainwater harvesting presents and opportunity for supplementing water supplies allowing for self-reliance and sustainability.
Sustaining the environment contributes to overall conservation of our precious natural resources.
