Comparison of 2011 & 2012
for Water and Sewer bills in El
this calculator to compare costs under the old 2011
rates, current 2012 rates, and proposed new 2012 rates.
This calculator compares the change to 2011 rates to 2012 with and
without the rate change for switching from 70/30 to 50/50 cost
allocation, with costs paid equally by the fixed basic charge and
this calculator to compare costs
among any year from 1999-2015. Rates for 2012-2015
are proposed but not yet adopted. Pre-2008 costs are computed with
the rate formulas for pumped water, not gravity-feed water.
All graphs on this page depict water and sewer costs for Single Family
Residential service. Contents were minimally updated on 2/18/2012, a
further update will finish revision to reflect rate comparisons for
three different rate schedules:
new 2012 rates primarily shift from 70/30 to 50/50 coverage of
costs by the the two main components of water rates. This means that
current 2012 rates recover 70% of actual costs from consumption
charges, 30% from the fixed base charge assessed in each 2-month
billing period. The proposed new rates shift to recoving 50% of costs
from consumption charges, 50% from the fixed base charge. Several other
changes in the rate structure for particilucar rate classes other than
Single Family Residential respond to findings of the Cost Of Services
study completed last year.
- 2011 rates, which were in effect through 12/31/2011.
- Current 2012 rates, effective 1/1/2012. These rates
were approved and in a previous year.
- Proposed new 2012 rates, subject to a Proposition 218
hearing on March 23, 2012.
Proposed single Family Residential
rates are approximately cost-neutral relative to the current 2012
rates. Individual bills can vary, depending on water consumption and
especially on sewer flow, which is set annually the measured minimum
winter water consumption for each customer. Billing is especially
sensitive to sewer flow.
Service costs for water and sewer:
Sample case for one residence
This web author's own 2011 bills provide the basis for the sewer
charges used in the two graphs immediately below below. If the
currently expected 2012 rate schedule is applied to my actual 2011
billed consumption, my average billing would be for 2,503 cubic feet of
water consumption and 1,159 cubic feet of sewer (wastewater) flow.
Reductions in sewer billing offset increases in water cost in the low
range of consumption to make the total billing and the proposed 2012
rates nearly cost-neutral relative to the current 2012 rates.
Change in cost between the current 2012 rates and the proposed new 2012
rates would be:
|Water costs would change (increase) by....
costs would change (decrease)
billing would change (increase) by ...
minimum winter water consumption, 1,159 cubic feet per 2-month
billing period, is the basis for computing
sewer consumption charges. More precisely this represents flow into the
sewer, assumed to be equal to water consumption at a time when
irrigation normally is shut off. This determines the sewer cost applied
in each billing period for 1 year at a time. In my case the 2012 rate
schedule produces a 4.4% decrease in sewer costs.

at the top of this web page to check results for consumption numbers
for water and sewer usage from your own bills.
Graphics below are for comparing the 2011 rates with the current
2012 rates, these do not incorporate the shift from 70/30 to 50/50
rates. These graphs will be updated to reflect the proposed 2012
rate structure .
