Rate Study
Background
2019 Rate Study
•Consistent with City’s Strategic Plan goal:
›Ensure that water and sewer rates are properly set to provide the appropriate level of
revenue
›Utility Rates meet cost-of-service requirements and be equitably distributed over the
customer base
•Solicited proposals from nationally recognized utility rate setting firms and selected Raftelis:
›National firm specializing in Water and Wastewater financial planning, rate setting, public
outreach and IT for Utilities
›120+ Staff Consultants
›Raftelis project staff have worked on hundreds of water and wastewater rate studies in CA
›Local water and wastewater projects include City of Orange, Lakewood, Long Beach,
Huntington Beach, Signal Hill, Newport Beach, Mesa Water District, Trabuco Canyon
Water District to name a few

Why Water Rate Changes
Are Needed
7
•Last water rate increase was in 2014
•City’s costs to provide water service are rising
•Fund critical water infrastructure repair and
replacement capital costs projects
›City plans to invest an average of $3.28 million per
year, over the next 5 years, starting in FY 2021
›Total cost of the planned five year CIP is $16.4
million
›Issuance of a $12 million bond will be required
•Implement rate structure changes to increase fairness
and equity in accordance with Prop 218 requirements
Water, Sewer,
and Trash vs CPI
8
Across the country Water,
Wastewater and Trash rates
are rising faster than normal
goods/services.

What Is Funded By The Water Rates You Pay
•City’s water utility is funded entirely by the money it receives from the
water rates on utility bills sent to customers
•City’s water utility is an enterprise fund—it does not receive money from
taxes
•The water rates you pay on your utility bill fund all the operating costs and
the infrastructure investments for the city’s water system

›Provide sufficient funding to quickly and efficiently award construction contracts
›Mitigate financial risk of potential asset failure
›Enhance credit rating for more cost-effective debt financing options
•Raftelis’ recommended reserve policy

Proposed Water Rate Structure
Why the Proposed Changes?
•Traditional rate setting groups customers by class (SFR, MFR, Commercial, Irrigation, etc.) instead of
meter size because customers in each class tend to use water similarly.
›e.g., 1” commercial customer has constant use throughout the year whereas 1” irrigation customer
has summer peaking periods. They use water very differently. We set rates based on how
customers use water.
•State Water Conservation Policies (SB 606 and AB 1668) will require each water provider to calculate
water budget by June 2022.
›Possible fine for providers that do not meet budget by 2027.
›Smaller Tier 1 (17 hcf instead of 26 hcf) will incentivize conservation to make sure Seal Beach
stays within its budget.
•Fixed charges are being calculated in proportion to American Water Works Association hydraulic
capacity factors – the industry standard for setting fixed charges. Thus, the fixed charge increase for
larger meters.
19
Proposed Water Rate Structure (Cont.)
•Single Family Residential (SFR)
›No change to structure, but a change to the tier widths to better align with average water use
›Tier 1 = average yearly water use for SFR account (17 hcf). This is average indoor and outdoor
water use for the average home.
•New Multi-Family Residential (MFR) class with tiers by dwelling unit .
›Quadplex would get 4 x 17 = 68 units in Tier 1.
›This is more equitable for large MFR customers.
•Commercial
›Uniform Rate; commercial customers generally have much lower irrigation needs.
•Irrigation
›Uniform Rate; created because this class has the highest peak summer water use
•City
›Uniform Rate

•A Sewer Rate increase was last issued in 2005
•Implemented a series of fix fee increases (aka capital charge) over 10 years ending in

›Primary goal was to raise revenue to repair the failing sewer infrastructure
•$3.3 million Sewer Revenue Bond issued in 2011 to fund sewer capital projects

Why Are Wastewater Rate Structure Changes
Needed?
•The proposed rate structure is more equitable
•Rate structure does not charge in proportion to meter size, but charges in proportion
to estimated sewer flow.
›e.g., park with 2” meter may only have a small bathroom; the rest of water use is for
irrigation and does not go into the sewer.
•Industry moving away from meter size as estimate of potential sewer use.

•Residential (SFR) sewer flow = minimum water
use during the year (minimum billing cycle)
•Total SFR Sewer Charge = Flat Charge + lowest
billing cycle use (hcf) x $ Volumetric Rate ($/
hcf)
•SFR sewer use has a minimum and cap (4 hcf
and a 24 hcf cap, bi-monthly)
•All other customers sewer bills vary every billing
cycle = Bi-monthly fixed charge + Sewer Rate ($
/ hcf) x water use x return to sewer (RTS) factor.
•RTS = 100% for MFR, 90% for Commercial and
50% for City.
Leisure World Calculation
•Leisure World currently does not pay sewer charges even though it discharges sewage through a
City-owned pipe connected to the Orange County Sanitation District.
•Raftelis and City Staff assessed an equitable rate based on the cost to maintain/replace the pipe
and LW’s proportionate share of sewer flow:
›Proposed rate is the capital cost of the sewer pipe ($1M) serving Leisure World divided by 80
years (i.e., the expected life) plus yearly O&M
›Pipe cost is prorated for Leisure World’s contribution to sewer flow (95%)
•Leisure World’s fixed monthly sewer charge:
›$79.17 for O&M (95% of $1,000)
›$1,019.25 for capital maintenance/replacement of sewer pipe (95% of $1M / 80 yrs)
›TOTAL: $1,098.42 per month
37
Navy Sewer Calcs
Sewer—charged monthly
•Navy represents roughly:
›5.4% of total miles of sewer pipe collection system
›15.2% of total sewer flow
•Annual capital cost x 5.4% x 15.2% = $10,812
•Annual O&M cost x 5.4% x 15.2% = $808
•TOTAL annual sewer charge = $10,812 + $808 = $11,620
