Odd numbered homes irrigate on odd numbered days and even numbered homes irrigate on even numbered days. Your sprinkler controller can be programmed to do this. This helps with water system peaking (too much water being used at the same time) which can stress a distribution system. This will be in place until further notice. You do not need to water your lawn every day to have a healthy lawn.
