On January 1, 2016 a new rate structure and new rates went into effect – the first increase since 2012. The new rates are based on the 2015 Cost of Service Analysis, an in-depth study completed to ensure costs are allocated accurately and fairly among all customers.
The rate restructure went into effect January 1, 2016 and was reflected in water bills issues on or after March 1, 2016. A 4% increase across all water service rates, fees, and charges went into effect May 1, 2016 and will be reflected in water bills issued on or after July 1, 2016.
The rate restructure that went into effect January 1, 2016 included three elements:
An increase in the bi-monthly fixed service charge for all customers;
The establishment of a new bi-monthly watershed management fee based on meter size for all customers;
Adjustment to the tier rates for all customers.
An additional 4% increase became effective May 1, 2016. In addition, the new Sonoma County Water Agency (SCWA) pass-through charges were established. If the SCWA charges to MMWD exceed the amount we have already accounted for in the budget, MMWD can pass through the difference to customers.
The tier breaks for single-family residential customers stay the same, while the tier breaks for duplex and multi-family residential customers have changed. The tier breaks for all other customer categories (single-family irrigation commercial, irrigation, institutional, recycled water, and raw water) remain the same.
For 79% of single-family customers, the current fixed service charge will increase approximately $5 per month and the new watershed management fee is an additional $5 per month as well. Customers with larger meters have higher increases for the bi-monthly fixed service charge and watershed management fee.
The tiered part of each water bill covers customers’ actual water consumption, using a system of four different tiers based on the amount of water used. All four tier rates for residential customers changed.
On January 1, 2016 tier 1 rate increased from $3.74 to $3.81 for 1 CCF, or 748 gallons;
Rates in tiers 2 through 4 have been reduced by varying amounts depending on the customer category (single-family; multi-family; duplex.
