For about $300 you can offer your home buyers a space-saving 50-gallon Rainwater HOG unit.
The system includes a 1,700-gallon underground cistern with a childproof lid, a filter package that is suitable for roof areas up to 3,750 square feet, and a submersible automatic water pump with integrated on/off control and run-dry protection.
What differentiates this product is its durable tank manufacture.
It is the largest tank of its kind to be manufactured by injection compression molding, and the wall thickness is equal in all areas of the tank, which creates such stability that the tank won’t collapse if it remains empty.
The Future of Water
By learning the mechanics of rainwater catchment and understanding basic differences between the options available, you can help your home buyers reduce their water bills and live a more sustainable life. But equally important is to be water-wise in all areas of the house and to plan ahead for water conservation methods.
“If you don’t build a rainwater system on the front end, it gets hard and expensive to put it in afterwards because the best way to capture rainwater is in an underground tank with a hookup to drip irrigation,” says Jerry Yudelson, author of Dry Run: Preventing the Next Urban Water Crisis. Yudelson also notes that builders should provide home buyers with water-conserving appliances and smaller lawns. “If you look at the EPA WaterSense program, the number one way to cut water use is by reducing the size of the lawn and using good xeriscaping. But lawns are a cultural issue, and builders simply build for the market and are not creating change.”
WATER CLASSIFICATION
This list is a quick reference pulled from “Rainwater Harvesting & Plumbing Codes” by Susan R. Ecker with Rumsey Engineers. Here, she explains the different “types” of water that could be involved in a residential project. Of note, harvested rainwater is neither reclaimed water nor is it graywater.
Black water is toilet waste.
Graywater is untreated waste water that has not come in contact with toilet waste. Graywater includes used water from bathtubs, showers, sinks, and water from clothes washing machines. It does not include waste water from kitchen sinks or dishwashers.
Reclaimed water is water which, as a result of tertiary treatment by a public agency, is suitable for a controlled use. The controlled use can be the supply of reclaimed water to water closets, urinals and trap seal primers for floor drains and floor sinks. This system is usually called a “purple pipe” system because the reclaimed water is conveyed in pipe that is purple in color.
Harvested rainwater is storm water that is conveyed from a building roof, stored in a cistern and disinfected and filtered before being used for toilet flushing or landscape irrigation.
