If your water bill is unusually high, but has not be estimated, there are a few things you can do to investigate the situation. First, check for leaks. Small leaks can add up quickly. Just a 1/8-inch sized leak consumes more than 3,500 gallons per day. While most leaks are easy to find, others may be more difficult and can often be left undetected. Start by checking your toilets. Toilets can lose hundreds of gallons of water when leaking. The MPWC can provide you with special tablets for detecting toilet leaks free of charge. You can also put a few drops of food coloring in your toilet tank and wait a few minutes. If the color shows up in the bowl, you have a leak that needs to be repaired. Check indoor and outdoor faucets and replace worn gaskets and washers. Look for drip stains beneath and behind your dishwasher and washing machines. Check leaks in your sprinkler system, including damaged sprinkler heads.
