Here’s the release from the City of Salida (Lonnie Oversole):
Water restrictions for the 2012 irrigation season will again be on a voluntary basis. Citizens are encouraged to follow the same restrictions that had been in place in past years, which includes even/odd day watering and no watering between 10:00 a.m. and 4:00 p.m. Should you choose not to follow voluntary water restrictions, there will be no enforcement or penalty.
Keep in mind if you water during the heat of the day, you will loose 50% of the water you apply to evaporation, which is the reasoning behind not watering between 10:00 a.m. and 4:00 p.m. The even/odd day system has half the city watering on one day and the other half on the next day. This provides better water pressure for all customers and fire fighting personnel.
