Water bill

The water bill just arrived for the last 7-1/2 months, and it is clear that we have plenty of work to do in this area. The main problem is that the pipes in our house have frozen in past winters, and the town tells us to run a faucet at a pencil-diameter stream from December through March. This keeps the water moving from the main into our line, and prevents freezing at that junction. They then adjust the bill for that usage. This mitigation has been going on since about 1980 or so. Apparently, it is cheaper for the town to do this than it is for them to dig up the street when the pipes freeze out at the street. So, we ran the water during the winter, and I couldn't really come up with a workable idea for using the water. We do have a large Finnish soaking tub where we could store a few hundred gallons, but, according to the town, we used 6800 cubic feet, which is 51000 gallons. We would have to fill and empty the giant tub at least once a day, and what to do with the water? Make a skating rink the size of Boston Garden? Buy 6 tanker trucks, and use the water to fill the community pool in the spring? Somehow run it down to the local farm for springtime irrigation? Disobey the town and let the pipes freeze? It makes me ill.

The second problem is that the town calculated our household's usage at 4200 cubic feet, or 31500 gallons, or 3-1/2 tanker trucks' full. Over 220 days, that's 143 gallons a day -- way too much. As a check, I just looked the water meter, and we've used 1215 cubic feet -- one tanker truck -- since April 1. That's 174 gallons a day -- we're getting worse! Or, possibly, the town uses a standard allowance for the winter offset, and we poured less than 51000 gallons down the drain last winter. If they use 450 gallons a day as the standard, that would make sense.

While I'm trying to think of ideas for using all of that wasted water, I might as well gather the low-hanging fruit of savings in our daily usage. We take an average of 4 showers a day, using probably 85 gallons. We do an average of a load of laundry a day, using about 15 gallons. We run the dishwasher once a day, using say 10 gallons. OK, that leaves toilet flushing, hand washing, and "rinsing". If we say 70 gallons are for flushing, then we could cut that down to 22 gallons, but only by replacing 4 toilets. At our marginal water/sewer rate of $13.88/100 cubic feet, we would save about $325/year (and almost two tanker trucks per year). But the savings would also bring our marginal rate down to $8.72/100 cubic feet, giving savings of about $210/year. So it would take several years to pay for itself. However, we have some pending repair costs for our existing antique modern toilets, so if I count those costs as saved, the payback time is shorter.
