Great subject! At the end of 1996, my son helped install a graywater collection system with 1/4 turn valves at each fixture, plumbing that fed a poly-drum reservoir, and an automatic pump station to spread the water to any yard irrigation zone. Combined with body-waste management, such as urine in the garden compost, we now can live well on 1/2 to 1/5 the potable community water used in the past.
Replacing 18-36" of soil with compost makes for Awesome tree and garden growth, +graywater holding.
Most interesting presentation, I've a friend overseas in an arid country and would very much like to have a transcript of your talk. Is there any possibility of getting a hold of the text ? It would be very helpful, thank you.

Jdlifsey - Greywater is similar to septic tanks in that it treats waste water on the property site. However, If you have a septic tank and install a greywater system you'll be putting a lot less strain on it as it will be principally be dealing with the 'black' water, as the 'greywater' will be used again for irrigation.
ommcurly - yes every system would have a simple 'on/off' valve so it can be turned off if it either gets too cold or saturated with rain outside.
Thanks, this is a great presentation! Can the systems shown in this video be used in regions with colder winters? Could you turn it off at the beginning of the winter and then back on in the spring?
Hi, Laura and Greg.... great presentation, very detailed, thourough and clear. I'm ready to get my laundry done. one question, can I get a reduction of bill from SFWater Dept after they see my system set?
Hi Rennea - The San Francisco PUC doesn't offer bill reduction incentives at this stage (although it's a great idea). They do currently have an incentive that discounts the purchase of rain barrels through 2010. Santa Rosa and North Marin do offer greywater incentives like this and more will follow so it's worth contacting you local utility. Thanks for the question, Greg
here in germany I don't know of using gray-water. I only know about slightly filtered rain water, for the toilet and the washingmachine.
in CA there might be too little rain, but here there is enough.
If there is too little rain one should think about not having a big lawn or have resistant trees give shade.
Some houses don't even have a connection to the sewagetreatmentplant why are they legal? there is plenty of stuff in our waste that doesn't break down and that is harmful.
Wow, I am very impressed with this presentation! I really got a sense for what my options are! So glad to hear it's legal in CA now, and definitely interested in learning more about what the ROI would be for an installation. With water prices skyrocketing in SoCal, I'm sure it would be a very quick payback. Also, with the water shortages and restrictions in place, installing a system is crucial!

I am in the process of building a home. What are the "proven" designs of grey water?

Isn't greywater just going back to septic tanks (w/o toilet water) instead of using sewers?

Great Introduction to understanding grey water systems. This presentation shows how affordable and practical grey water is for almost anyone!
