Rainwater Harvesting Advantages

Drought Mitigation

Many parts of the United States are in (or are about to enter) a drought period, facing possible water restrictions. In February 2009, the Governor of California ordered that mandatory water rationing and mandatory reductions in water use may be introduced.

Rain tanks, or rain barrels, collect fresh rain water from the home roof and store it for times of drought. Modern rain tanks are sealed from light, animals and vegetable matter so the water stays clean for months.

Proponents of global warming warn that weather patterns are already changing and traditional rainfall levels are expected to drop in many areas.

Green Living

Green living is now becoming a way of life for a majority of Americans. People are conscious of their ‘carbon footprint’ and are seeking methods to reduce the future impact on the environment and climate. 20% of California’s power consumption is used to collect, transport and treat water.

In areas of major urbanization the environment is suffering from increased run-off that cannot soak naturally into the ground. As a result, aquifers are not filling at a rate fast enough to restore their pre-urban levels.

Saving Drinking Water

Water is a limited resource and the cost of its supply is certain to rise in the next few years. Most major water collection and distribution projects in California were completed over fifty years ago and no new major rainwater catchment projects are planned. Water restrictions are nothing new in California, but since the last major drought in the early 1990s, the state’s population has grown by 9 million to a total of 38 million.

In a press conference on March 12, 2009 the governor plainly stated that, with increased demand and limited supply, Californians can expect to pay more for water in the future.

But why use good drinking water on the garden or to flush toilets? Over 40% of water supplied to most suburban households is used on the garden. This is not the best use of a product processed for human consumption. Besides, most plants enjoy the slightly acidic and soft qualities of rainwater.

Bushman rainwater harvesting tanks maintain a high quality of rain water with gutter guards, insect filters and first flush devices that divert the first rains of the season to the drain. All tanks are opaque and do not allow the growth of algae. Tanks are made or lined with food grade quality polyethylene.
