The Zone 7 Water Agency, the District’s water wholesale supplier, adopted new water rates on Oct. 17, 2018. The “Zone 7 Cost of Water” rate on your bill will increase from $2.99 per unit to $3.48 per unit (1 unit = 748 gallons) effective Jan. 1, 2019. DSRSD passes through the cost of water purchased from Zone 7, charging customers based on the volume of water they consume.

Bimonthly Water RatesEstimate your next bill with AquaHawk Alerting!

DSRSD customers receive six water bills per year, one every other month. Your bill is a combination of consumption charges (based on the amount of water used) and fixed charges (the same on every bill). Your bill is the sum of applicable charges in Table A + Table B + Table C.

Table A – Consumption Charges for the Cost of Water and Power

These volume-based charges cover the cost of potable water purchased from Zone 7, power, and recycled water. 


Rate per Unit
2018
2019
Zone 7 Cost of Water (applies to all potable water customers) $2.99  $3.48
Power Charge (applies only to service locations where water must be pumped due to elevation) $0.28  $0.28
Recycled Water (covers production and distribution) $4.14  $4.57


Table B – Consumption Charges for Potable Water Distribution

The District charges to distribute water to your address and maintain the water system. When the District declares a water shortage, rates increase in stages to encourage conservation and recover revenue needed to operate the water system with declining water sales. (Learn more about why water bills often go up in droughts, based on research by the Public Policy Institute of California.)

Normal rates are in effect. Applicable consumption charges are shaded below.

Table C – Fixed Charges for All Customers

All water customers pay a bimonthly fixed charge based on meter size. Most of the costs to operate the water system do not vary with the amount of water used. Revenue that is predictable throughout the year stabilizes rates and improves the District's credit rating, thereby reducing the cost of future borrowing.

Rate Changes

In addition to any rate increases adopted by Zone 7 Water Agency, water rates generally increase each year on Jan. 1 based on the annual change in the Consumer Price Index (All Urban Consumers for San Francisco-Oakland-Hayward). However for Jan. 1, 2019, DSRSD customers will not see a water rate increase.

The DSRSD Board of Directors may change rates at other times as a result of rate studies or other factors. DSRSD notifies customers when rate changes are proposed, as required by Proposition 218. Customers are encouraged to attend public meetings regarding rate changes and submit written comments. For more information on Proposition 218, see the following guides:
