4. Provide Residents & Staff Actionable Information
Cloud-Based Access (any web browser)
 Provide customers with comprehensive self service
 View consumption 24/7
 Prevent and manage high bill complaints
 Estimated and project bills
 User-set thresholds
 Leak alerts
 Provide staff the tools to operate efficiently
 Proactively communicate with customers
 Built-in staff notification to customers on potential leaks
 Monitor accounts in bulk or by segment
 Water restrictions
 Abnormal usage (potential leaks)
 Real-time data for customer service to diagnose complaints

5.  Testing performed by MARS
Company in San Antonio
(top of the line testing operation)
 20 out of 23 meters failed AWWA
standards at one or all flow rates
 Analysis of test results and
current meter population
indicates an inaccuracy of 12.7%
 A contractual performance
guarantee of 10% improvement
in accuracy can be incorporated
in a solid-state meter upgrade

6. Selecting a System for Alamo Heights
 Regardless of network type, solid-state meters
should be pursued, maintaining high accuracy
throughout system life
 Real-time data (AMI) can be delivered through
cellular or fixed-base technology
 SAWS is currently pursuing one of the countries
largest fixed-base, solid state meter upgrades
 Alamo Heights would not achieve similar
economies of scale and would require
negotiating with CES and increase in long-term
capital assets to be managed
 A cellular system is the most cost effective,
when including all networking costs over a 20-
year period

Incremental Opportunities
(Post-Project)
The surplus cashflow from a
federally reimbursed grant could
be used for other pressing needs.
Alternatively, it could be used to
buy-down the financing, saving
$950k in interest.

9. BACKGROUND ON RATES
9

10. 21st Century Water & Wastewater Rate Facts
 Average utility has been increasing rates 5-6% per year, a trend that is expected to
continue
 American Water Works Association (AWWA) forecasts that water and wastewater
rates across the U.S. will triple in the next 15 years
 30-40% of utilities charge rates that do not cover their costs
 Rate adjustments are primarily due to reasons beyond a utility’s direct control –
inflation, necessary Capital Improvement Plans, wholesale costs, and other indirect
expenses
10

11.  City has not adjusted rates since 2020
 Current thin rate margin, capital
improvement needs, and escalating
operating costs are driving a need to
reassess rate plan
 Current rates will not continue to
support operating costs, and do not
recover funding for CIP projects or
additional debt service payments for
new debt
 New rate plan will include increased
revenue and capital contributions from
meter program

CURRENT AND FORECAST REVENUE REQUIREMENT

23. WATER & WASTEWATER
RATE PLAN SCENARIOS
23

24. Forecast with No Rate Increases
24
With no rate
increases, the fund
balance will be
negative by 2028.
Net Operating
Revenues would
stay positive
through 2024, but
not enough to fund
projects with cash.
Debt coverage
ratios would be
insufficient by 2026.

25. Proposed Rate Plan
 Recommend implementing a 5-year rate plan with
adjustments on October 1 of each year 2023 –
2027
 Council retains the ability to adjust annually as
necessary
 Assumes no change in fundamental rate structure;
uniform percentage adjustments for base and
volume charges
 If CIP or operational assumptions change, a
significant impact on the rate plan is to be expected
25
Given the relative
amount of CIP
expenditures and
significant increase in
debt service expenses,
we recommend
reevaluating the rate
plan every 2-3 years

26. Proposed Rate Plan | Summary
26
The proposed rate plan
maintains the current
rate structure, while
increasing rates to cover
operational cost
increases and new debt
service payments.
The combined impact on
average residential
customer bills is
$2.96/month (4.7%) in
year 1.

30. Proposed Rate Plan – Impact on City Utility
30
With $14.0M in
new debt
issuances* and
moderate rate
increases, the
fund is forecast to
remain in sound
financial
condition,
including debt
coverage ratios.
*Assumed 20-year
term debt @ 4%.

31.  The proposed rate plan enables the City to fully
fund all water and wastewater costs and CIP over
next decade
 Will enable the Utility Fund to operate self-
sufficiently with no need for subsidies from fund
balance
 Enables the City to provide safe drinking water
and effectively treat wastewater continually for
forecast period
How Does Rate Plan Benefit Ratepayers & City?
