Sprinklers can be very wasteful of water and money. A lot of people and business have them on timers. Those timers do not take the weather into consideration and will let them turn on when it is raining. This is one time that they do not need to turn on.
This is a waste of water that everybody is paying for. It is not only for people who are paying for city water but everybody else also. It costs money to run a water pump and every time that the water is running, the pump is too.
Another problem with sprinkler systems is that it is easy to forget to turn them off. They may run for a lot longer than they really need to because of this. Sprinkler systems can run out a lot of water in a matter of a few minutes.
Water is not really free for anybody. For people in the city, it raises their water bill while people who live in the country will have the different show on their electric bill. It is more noticeable on water bills because the electric is higher in the winter from heating costs so people do not realize that it really is costing them money.
