SMWD does not charge customers based on income status. However, the District’s rates are designed to ensure that essential indoor drinking water is provided at the lowest cost to all customers, known as “Tier 1” pricing. A single-family residence customer falls under this category when water usage is 0 to 9 ccf (1 ccf = 748 gallons) within one billing cycle. A multi-family residence customer (condominium or apartment) falls under this "first tier" when usage is 0 to 7 ccf within one month's usage. View SMWD's water and sewer rates.
