Council’s Financial Policy
Utility rates and rate structures for water and sewer services will be
constructed to target full cost of service recovery. Annually the Town will
review and adopt water and sewer utility rates and a rate structure that
generates revenue sufficient to fully cover operating expenses, meet the legal
restrictions of all applicable bond covenants, provide for an adequate level of
working capital, and recover applicable general/administrative costs.

•The rate study should address both current
and future system needs.
•The Council should have a clear understanding
of the rate study.
•There should plan for informing the public of
any rate study and subsequent adjustments.
POLICY GOALS FOR RATE STUDY
WESTLAKE
UTILITY RATE WORKSHOP
5
Current Water and Sewer Revenues are underperforming
(revenues<expenditures) by approximately 3% and 23% respectively. The
proposed changes will increase water revenues to 9% above expenditures.
Sewer revenues will increase; however, revenue would still be
underperforming by 9%.
The Town’s wholesale wastewater provider, Trinity River Authority, increased
treatment costs approximately 23%, from $3.902/1,000 gallons to
$4.788/1,000 gallons.

•Ratemaking is the process of allocating
revenue requirements to customers
via the price of water

AWWA Policy
1. Every water utility should receive sufficient revenues
from water service and user charges to enable it to
finance all operating and maintenance expenses and
all capital costs.
2. Water utilities should maintain their funds in separate
accounts. Such funds should not be diverted to uses
unrelated to water utilities…
3. Every water utility should adopt a uniform system of
accounts …
4. Water rate schedules should distribute the cost of
water service equitably…
