I highly recommend buying this book to learn more about the great utility of installing a Greywater system in your home.  For more information please visit design.netand call Monty if you need the peace of mind of a qualified, licensed and bonded plumber to install your system.

If you make a simple change in cleaning products and connect a few pipes to a holding tank and then pump that water into your yard for irrigation, you can save ~20% on your water bill by reclaiming your water from washer machine, bathroom sinks and showers.  In combination with rain barrels, you can easily supplement your irrigation, conserve water, and save money and the environment by using phosphate free soaps.

In Southern California, the average household uses 100 gallons/day per person and 60% of that goes towards irrigation.  Water comes from two main sources in So Cal, the Colorado River and the California Water Project via aqueducts.  This mass transfer of water from distant sources requires 20% of California's energy supply.  Water reuse and reclamation are essential methods to improve our utilization of existing water sources.

Monty's offers creative solutions for water use and reuse via gray water reclamation.  A gray water system can take 20% of the water you currently use for showers, bathroom sinks, and washing machines and utilize it for lawn irrigation.  This effectively reduces your consumption by 40%!

Is it legal?  In California, their is legislation in discussion to legalize the use of Gray Water for irrigation as SB1258.  It is also estimated that thousands of homeowners utilize some sort of gray water reuse system and/or rainwater collection to supplement their irrigation needs.
