As you may know, the City of Houston just implemented a stage one condition of water rationing. (Lawn watering permitted for odd-numbered addresses only during the dark of the moon on alternate Wednesdays. Even numbered houses on the fifth Friday of months that have an "R" in them. The few addresses that are denoted with "1/2" are neither odd nor even, but are called 'brown'.)
Meanwhile, the public works office has hired 55 new people to hold shovels upright as they labor with a backlog of over 700 water main breaks. They say they "fix" about 100 leaks per day, but more than that are reported. They should emulate our governor and try prayer.
There's two leaks close to my house, each about two blocks away.
If I had a 100 gallon tank and a small pump, I could water my lawn.
