Study goals and objectives
•Multi-year financial plan, cost-of-service, and rates
which sustain the long-term financial health of the
water and water reclamation utilities
›Securing of current and future water resources
›Fund system improvements
›Fund preventative maintenance programs
›Develop and fund a reserve policy
›Ensure timely payment of annual debt obligations
›Development of rates that provide revenue stability and
promote conservation

Drivers for increases
•Energy costs
•Aging and additional infrastructure
•Increased regulatory pressures
Previous rate increases
•Previous rate increase plan initiated in 2013
›Water
–April 2014 (+6.5%) (cumulative 6.5%)
–January 2015 (+6.5%) (cumulative 13.4%)
–January 2016 (+4.7%) (cumulative 20.6%)
–January 2017 (+4.7%) (cumulative 27.9%)
›Water Reclamation

1. Rate-setting process

Industry publications provide
the framework
•American Water Works Association,Manual M-1, Principles of Rates,
Fees, and Charges
•Raftelis Financial Consultants,Water and Wastewater Finance and
Pricing
•Water Environment Federation,Financing and Charges for Wastewater
Systems

The rate -setting process

Financial Plan
Cost-of-Service
Rate Design
1 What level of revenue is needed to
meet expenditures, reserves, and
bond covenants?
Is each customer class paying their
equitable share?2
How should costs be recovered?3
Step 1: Financial plan
9
Revenues at Existing Rates
and other income
Projected number of customers,
consumption, and revenues
O&M & Capital Budget Forecast of expenditures
Financial Policies Apply financial policies which inform
the cash flow analysis
Capital Funding Sources
Rates, Debt, Capacity Fees
Identify level of rate revenue, bonds
and fees for financing capital projects
Cash Flow Analysis Summary of projected revenues,
expenditures and rate increases
Revenue Increases Adjust revenues to meet annual
expenditures and financial policies
Step 2: Cost -of -service analysis
•Determines cost to provide service to each customer class
based on the demands they impose on the utility
•Recognizes customer classes’ differing service characteristics
•Costs will vary by customer class
10
Water Wastewater
•Average demand
•Peak demands
•Number of customers by class
•Number of meters by size by class
•Billable contributed flow
•Number of customers by class
Step 2: Cost -of -service analysis
A multi -step process
1.Determine revenue required from rates
2.Assign operating and capital costs based on
system facility or function in the system which
incurs that expense
3.Allocate those costs based on how facilities
are designed and operated within system
4.Distribute allocated costs to customer classes
based on their demand characteristics
11
Step 3: Rate design
•Method of recovering the cost to provide servicefor each customer class
•Water and wastewater rate designs typically consistof a monthly fixed charge and a volumetric rate
•Fixed charge
›Meter maintenance and meter reading
›Customer service, billing, and collection, general admin
›Portions of salaries and benefits and other general fixedexpenses (utilities, uniforms, office equip., maintenance,etc.
›A component of capital costs –readiness to serve
12
Step 3: Rate design
•Volume rate, $ per 1,000 gallons
›Water volume rate generally recovers the cost to
collect, treat, and distribute water to customers
›Wastewater volume rates generally recover cost to
collect, treat, and recharge of treated effluent
13
Water and Water Reclamation
utility general assumptions
•Each utilities’ financials are separated into funding for
operations and funding for capital projects
›Operating cash flow
–Shows the ability of rates for each utility to meet annual O&M,
debt, transfers to the capital fund, reserves and debt service
coverage
›Capital cash flow
–Shows the ability of bond proceeds and rate revenue required to
meet annual capital costs
•Study period: FY20 –FY24
•Test year rates: FY20
