It's $5.25 service charge plus about $5.50 per 1000 gal. in my neck of the woods. We use about 4,000 gal/mo. avg. Sewer is a fixed rate of $10-something. Family of 4, the kids are small. 'Bout 33 gal/person/day. Bill came to $36.06 last month.
On the issue of recirculating pumps in order to save water
. Seems kind of pointless to me. 100' of 3/4" inside dia. pipe is about 2.3 gal. Maybe my assumption about inside diameter is a little off, but anyway. So buying a setup to recirculate a few gal. per day doesn't seem to make economical sense based on "cheap" water and sewerage, but what do I know. I just like to argue.
