Initial comments

This is great! I am so excited to see the details that go with this awesome outline. I wikified the outline (to the 4th level deep), although maybe it should be wikified deeper (just keep adding ='s). What do you think? Maybe it is easier for you to work the other way, so the text outline is still at the bottom, and you can always just revert to your last save.

Thank you for getting this going, it is a great addition to the knowledge base on home greywater systems. --Lonny 11:58, 14 June 2006 (PDT)

who is the contact

I am interested in finding out more about this project. I live in santa rosa, not far from occidental. I would like to talk to the person, or group, who did this project.

thanks Mandeep waris12@yahoo.com

power consumption of the air pump

I called airtech and gathered some info about the air pump. I am assuming you used the JP40C. Its rated at 300 watts. Assuming that this is the only air pump used to supply all the aeration needs (both the drums and storage tank) and that it runs 24/7, it comes to about (300 x 24 x 30 ) 216Kwh per month. Lowest rate for 1kwh in our area is about 11 c. So it costs about $23.76 per month to run this pump. Could be more if you cross into higher tiers.

I am interested in recycling grey water but storing it in a pond. Any idea what type of aeration pump will do for just the 4 drums.


Does the pump HAVE to run 24/7? Seems like overkill, and a huge energy user (couldn't be practically used on off-grid alternative energy systems, it would need at least a 1000 watts worth of solar panel. not cheap.) --Naught101 17:30, 12 January 2008 (PST)
I think this calls for a page on non-mechanical methods of aerating water - e.g. allowing the water to run over gravel, or a tiered waterfall (making sure there's proper spacing to allow splashing). Don't know how effective it would be, and of course it depends on how much height difference is availablebut it shou ld at least reduce the need for pumping. --Chriswaterguy · talk 18:12, 12 January 2008 (PST)

No, I believe the air pump installed on this system only uses about 50 Watts. Here's a link to its specifications: Airtech 40. It's more than sufficiently aerating 700 gallons. GoodSignal 20:59, 12 January 2008 (PST)

Great project here.

I have some questions. How do you initially seed the bacteria when starting a new cycle every season?

Will adding some ceramic noodles such as the ones used in an aquariums help to sustain the bacterial colony?

With just aeration for the bacteria to feed on, will this be enough to produce a non hazardous water for flushing toilets?

If I add a UV sterilizer, similar to the aquariums to the water exiting the last drum and before being stored. Will this help to kill any remaining hazardous bacteria?

Thanks for all the details.
