Day in and day out, millions of people take a morning shower before starting their day. Some take a hot bath in the evening or soak in a hot Jacuzzi and some do both. And let's not forget the couple or more times a day we ALL spend at the sink brushing our teeth. Then there's also those homes that have to do several loads of laundry per week or more.
The average four person household can create well over 38,000 gallons of grey water each year from bath and laundries. So where does this water go? If you have a septic system like most houses, this mixes with your black water(created by flushing toilets) and eventually goes into the septic tank fields. It's possible ground or drinking water contamination could result. If you reside in a municipality it might go into the sanitary sewer system.
Having a gray water system provides homeowners with the option to filter grey water for use in watering gardens, yards, plants and even flushing toilets. Filtering grey water to be reused keeps septic tanks from becoming overtaxed with fluids. The sewer system also benefits from grey water because they will have less water to have to filter. And the costs range from $700 - $2100 depending on how elaborate of a system you want. Most states offer a tax break on grey water systems, so if you do the math then you will clearly see the savings to your wallet and the enviroment!!!
New home builders easily could incorporate this system in every new home for a just little bit more and add the costs of a basic system to the price of the home and give the option to upgrade the system in pre-bought homes. So what is topping them?
