Results of the 2016 survey will be documented soon in the format of This 2013 Survey.
353 California water service areas
were surveyed to check cost of typical residential water consumption late in year 2016.
water cost was 71.4% of the California average, 89.1% of the Sacramento
In California 22.4% of service areas had lower cost than EID, 77.3% had higher cost than EID.
Among 154 California sample of annual rate increases the average was 9.7% per year. EID's current maximum authorization averages 4% per year from 2015 through 2019.
Until then the 2016 survey's reportable data are in This Spreadsheet. Detail data for each of the 353 service areas will be added to the Library section later.
Expanded summary of EID standing in comparative costs:
|Average Monthly Cost||$52.00||$72.87||$64.51|
|Median Monthly Cost||$52.00||$69.48||$54.12|
|Percent of agencies Below EID Cost||--||22.4%||37.5%|
|Percent of Agencies Above EID Cost||--||77.3%||60.0%|
|Average Annual Cost Increase||4%||9.7%||8.9%|
|Median Annual Cost Increase||4%||7.5%||5.5%|

Sample set sizes were:
- 353 California service areas for current rates
- 40 Sacramento region service areas for current rates
- 153 California service areas for annual rate increases
About rate percentage increase data:
Most citations of annual increases are either a single-year increase or the average of multiple years of planned increases. Example: EID's average of 4% annually is from approval of consecutive maximum annual increases of 5%, 5%, 4%, 3% and 3% for 2016 through 2020.
This survey of California service areas uses data from agency web sites. This limits the sample set size for rate increases as a result of limited web site contents:
- Many web sites show only current rates.
web sites show rates for only two years, usually reflecting a change
adopted for only one year. This is especially common for private
companies, whose definitive rate information is in their annual rate
tariff filings with the Public Utilities Commission (PPUC).
previously small but now growing number of web sites post multi-year
rate increases, often as Proposition 218 Notices to their customers. A
majority of these show five years of increases.
- Virtually all cases of very small rate changes, including decreases, come from private agencies' filings of annual rate tariffs. These are minor corrections resulting from fine tuning that depends on the prior year's actual operating results, relative to expected results. The results are unpredictable small variations in the next year's requirements for rate-based revenues.

- The survey is based on residential consumption of 1,500
cubic feet of
water per month (3,000 cubic feet bimonthly). This is nearly identical
to EID's finding of an average of 3,057 cf bimonthly for residential
customers in a Cost Of Services Study, and it is the consumption level
used on most surveys done by
- Rates used for comparison are standard non-drought
rates. EID has no drought rates, but many, if not most, California
agencies use them when agencies declare their service area to be in
drought. The most common form of drought rates adds 30% to the cost of
top-tier water. Other variants exist; one is to increase the top-tier
rate by up to 50%, another is to assess higher rates on all tiers.
purposes of this survey "Sacramento region" is defined as service areas
within the six counties which are members of SACOG, the Sacramento Area
Council of governments.
- One agency in the Sacramento region, the Strawberry Division of the Del Oro Water Company, is excluded because its location and its rates both are virtually "on another planet". The survey found this to be the most expensive water service in California, at $304.36 per month. EID also supplies water in Strawberry at $52.00 per month. The Del Oro rates seem totally irrelevant to all other service areas in the Sacramento region.
