Residential Bill Calculator

Use our estimator to compare your bill at Stage 1 water shortage rates and Normal rates. Stage 1 rates were in effect November 1, 2015, through May 31, 2017 due to water shortage conditions. Normal rates (in Table B below the calculator), are in effect as of June 1, 2017 due to improved water supplies.

Be aware: the more water you use, the higher your bill. Compare your past and current water use on Aquahawk.

Step 1
Look at your water bill (see sample on right) to determine how much water you use in a two-month billing period.

(one unit is 748 gallons)
Look up your bimonthly water consumption. This figure is located on the bottom left corner of your bill. This customer used 11 units (which equals 8,228 gallons).

Bimonthly Water Rates

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
2017
Zone 7 Cost of Water (applies to all potable water customers) $3.29  $3.72
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) $3.79  $4.23

The 2017 Zone 7 rate shown above includes a scheduled rate increase, adopted in 2015 by the Zone 7 Water Agency Board of Directors, and a temporary surcharge, which the Zone 7 Board has extended through 2017. DSRSD is continuing to pass through the cost of water purchased from Zone 7, charging our customers based on the volume of water they consume. The recycled water rate changed because the Zone 7 cost is a component of that rate.


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.

Due to improved water supplies, Normal rates are in effect as of June 1, 2017. Applicable Consumption Charges are shaded below.

Residential Customers          
Tier 1 (1-10 units) $0.55 $0.62 $0.70 $0.97 $1.42
Tier 2 (11-34 units) $1.16 $1.46 $1.81 $2.33 $3.78
Tier 3 (over 34 units) $1.55 $2.01 $3.03 $4.34 $5.98
Commercial Customers (includes Industrial, Multi-Family and Institutional)
Winter (Nov-Apr) – all units $1.11 $1.21 $1.33 $1.68 $2.12
Summer (May-Oct) – all units $1.33 $1.55 $1.86 $2.34 $3.33
Potable Irrigation Customers
All units $1.55 $2.01 $3.03 $4.34 $5.98
Recycled Water Customers (See Table A)

 
Table C – Fixed Charges for All Customers

All water customers pay a 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

Water rates increase each year on January 1 based on the annual change in the Consumer Price Index (All Urban Consumers for San Francisco-Oakland-San Jose) and any increases adopted by Zone 7 Water Agency, the District’s wholesale water supplier. (On October 19, 2016, Zone 7 adopted a rate increase and a new rate structure, as explained in a public hearing notice DSRSD mailed to its water customers.) DSRSD notifies customers at least 30 days before annual rate increases take effect.

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:
