Do any of you have data on water consumption? > It would be really helpful if you could post to the list a summary of any information you receive on this topic. This is a topic I'd appreciate data on. Ewan Klein Following are a response from the list inquiry and another received independently: Phil, At Lake Claire Cohousing in Atlanta we use roughly 62 hundred cubic feet or 46,400 gals per month. This includes all units, common house and outdoor watering. (It's all on one meter.) We have 12 units with about 30 people in residence at any one time. The units were built with the standard water-saving faucets and toilets required by code. Otherwise, I can't think of any water-conserving measures we have taken. We have been watering outdoors fairly extensively because we have new landscaping and droughty periods in the (hot) summer. I hope this helps. Let me know if you need any more details. Shari Fradenburgh Lake Claire Cohousing, Atlanta --- >From Bruce Coldham at Pine St Coho in Amherst, MA: Note - includes exterior use, including watering of a substantial garden. I believe the six units represent 16 BRs total. Daily avg is 41 gal/BR. Marc, Here's what I know so far. I spoke with the official in Town who processes the water billings and we looked at Pine Street Cohousing's water consumption together (without regard to matching house and water meter serial numbers). Generally speaking, she was surprised to know that there were four people in some units because (she said) the water consumption would indicate only two people in residence ... everyone here lives a full year... no substantial time away. In Amherst the average household consumption is apparently around 100,000 gals per annum.... which is lower than the the national average by 15 to 20 % (according to Pat's averages... I have not gone back to my data from my MED days). We are using between 45,000 and 60,000 gals per year .... with Arthur using about 15,000. (He is a single parent in the very small unit in the middle). The atheo very small unit (Marcy) uses around 45,000 to 50,000 but she also uses twice the electricity that Arthur uses AND WE WATER HALF OF OUR COMMUNITY GARDEN FROM HER TAP. Here's the tabulation UNIT 1997 1998 Kastor(2) 45,600 45,600 Sax(4) 58,300 48,600 Sala(2+garden) - 53,100 Tuttle(2) 14,000 12,000 "Margolin" 33,000 27,600 Cohen (3±) 45,600 50,900 .. plus other half of garden Hope this helps Bruce
