Next "business day", gotta contact the water company. Our bill is usually in the $50/month range, yet the bill we got yesterday was $130 plus change. We HAVEN'T used over double the water we've been using in the past month. Mom's guess is the meter reader obviously didn't actually READ the meter, or misread it. I've looked under the house, no large water accumulations, so nothing is leaking. Besides, if we had a leak big enough to overly DOUBLE the bill, water pressure would be noticeably lower!
