Howโs the Future Look?
David Anders, CFO, Austin Water
Over last 8 years, Austin has been in a historic drought that has strained our water resources and finances.
I want to present some of the impacts of this drought and how Austin Water responded.
This graph displays the total actual water consumption from FY 2007 โ FY 2015.
FY 2011 โ 48.6BG and FY 2015 at 38BG โ 10.6BG reduction or 22% reduction in 4 years
Stage II โ Never been in stage II more than a month or two, now almost 5 years
Each year water demand under Stage II got lower and lower, difficult to forecast revenue
This graph displays the annual average residential water consumption per account actual figures from FY 2007 โ FY 2015.
2011 at 8,810 and 2015 at 5,840 โ reduction of 2,970 per account or 33.7%
FY 2006 was our highest Gallons Per Capita Per Day
Enhanced conservation measures and mandatory twice per week watering implemented in 2008
2010 we set conservation goal to reduce total GPCD to 140 by 2020.
With Stage II once per week watering we met and exceeded our goal of 140 GPCD by 2015.
FY 2015 GPCD at 122 total all customers and 67 for residential only
FY 2006 to 2015 190 GPCD to 122 GPCD = 36% reduction
This graphic provides the total water and wastewater revenue losses over the last 5 years.
Over 6 years, revenue loss totaling $148M, even with significant rate increases
In 2010 revenue losses were due to significant rainfall throughout entire year, including summer months
In 2011 AW saw no revenue loss. (actually saw revenue above budget by $17.7M or 4.3% due to extreme drought conditions experienced) This was right before we went into Stage 2 water restrictions
Each years water sales from 2012 to 2014 were less than the prior year. Forecasted revenue was reduced each year, but actual was even less than projected.
Each year between FY 2010-2015 was a new record low for water use
Most of financial impacts were on the water revenue impacting our water cash balances.
Prior to the drought and Stage II water restrictions, our cash balances were almost $40M
Declined to the low in 2014 of negative $15M = $55M reduction in balances
Debt service coverage also impacted significantly.
Our financial policy is to have a DSC at 1.50 or greater. During the drought we were much less.
2014 was the lowest at 1.25 that was just at our bond covenant level.
Low fixed charges at 11% when our majority of costs are fixed
Our Volume rates made revenue very volatile to weather conditions and drought
Increasing block rates for residential were much higher for higher volumes.
Focused our rate increases in the higher blocks to incentivize conservation and reduce low water user impacts
Cash reserves very volatile to weather conditions
Here are 2012 residential block rates. Red line shows average COS rate
Blocks 1-2 below COS and 73% of customers use less than 9,000 per month
High users subsidized low users โ there was sufficient usage by high users to subsidize the rates for low users
Rate design in wet or drought conditions is extremely volatile and risky
The Joint Committee on Austin Waterโs Financial Plan created in 2011
9 Citizens from 3 separate Commissions related to Austin Water
Committeeโs charge was to review AW financial plan and consider recommendations on changes to fixed charges, volume rates, reserves, and financial policies
Convened 3 separate times, 20 meetings, 3-4 hours at night
Include Committee, staff, rate consultants, citizens, financial advisors
Joint Committee recommendations
Fixed charges, went from 11% to 20%, then recommended 25%
Tiered Fixed Fee
Fixed fee based on monthly consumption, could vary each month for the customer
Higher fixed fees for higher users, lower fixed fees for low use customers
Strengthens conservation
Less volatility in tiered fixed charge as compared to tiered volume rates
Graphic shows the fixed revenue percentage of total revenue
In 2011 before the new flat fixed fee was implemented AW was at 11% fixed revenue
The new sustainability fee was in place during 2012 and raised fixed revenue to 17%
The Joint Committee recommendations were implemented in FY 2013 and raised the total fixed revenue to 20%
Residential rates are the most volatile rate structure. Each class has different fixed revenue totals to produce 20%
From 2013-15 Residential levels were at 27%
For 2016 residential levels will be 30%
For 2017 residential levels will be 32%
FY 2016 Approved Water Fixed Charges
Designed to push more of the fixed charges to higher volume users
Reduced bill impacts of average and low volume users of increasing fixed charges
Less volatile than recovering through volume charges
Final Recommendations: Volumetric Rates
Block 2 which was up to 9,000 gallons was reduced to 6,000
Any rate increase would add equal $ amount to each block. Over time, this has increased block 1-2 closer to COS level
Increase block 2 to the average cost of service rate over 2-year period
Note:
The current 5 block tiered intervals for residential will be changed to represent the following:
Block 1 โ lowest 10% of customers (0 โ 2,000 gallons)
Block 2 โ to the winter average water usage (2,001 to 6,000 gallons) representing โessential waterโ
Block 3 โ to the summer average (6,001 to 11,000 gallons) which allows for some irrigation at a lower rate
Block 4 โ up to the top 10% water use customers (11,001 to 20,000 gallons) representing some irrigation use
Block 5 โ top 10% water use customers (20,001 and over) representing primarily all irrigation
Tripled block 1 rate since 2012
FY 2016 rates in green
All blocks have increased by about $2 since 2012.
Block 1 increase of $2 is 171% above 2012
Block 5 increase of $2 is only 16% above 2012
FY 2017, rates will increase Block 2 to average COS rate
Only 18% of customers use less than 2,000 gallons per month
Only 18% under COS compared to 73% in 2012 rates
Created a Revenue Stability Reserve Fund at 120 days of operating.
Revenue Stability Reserve Fund Surcharge = $0.19 per 1,000 gallons for all customers
By 2018, the level of the fund will be about $50 million.
Restrictions โ 5-year funding, Use for revenue shortfalls only, Use 50% in one year, Council approval,
Operating cash reserves, goal to reach 365 days over next 5 years
This graph shows the average residential customer water bill increases since 2011.
29.5% water rate increase in 2012 due to the $4.40 fixed fee implementation.
Rate increases due to reduced consumption
Difficult to get public buy-in of rates,
Asked to reduce consumption due to drought, but increases in rates as well
When lake levels at the lowest point, it was possible for AW to go into Stage 3 or Stage 4 water restrictions, which would have more significant reductions to billed consumption.
Council approved drought rates that would be effective only if we reach stages 3 or 4
Stage 3 water restrictions would be declared if the combined storage reaches 600,000 AF (No outdoor watering)
6 billion gallons reduction and $27 million revenue reduction.
Drought rate would be $1.00 per 1,000 gallons in addition to water bill
Stage 4 water restrictions would be declared if the combined storage reaches 450,000 AF (No outdoor and more restrictions)
Additional 8 billion gallons reduction and $75 million reduction Drought rate would be raised to $3.00 per 1,000 gallons in addition to water bill
These drought rates are already programmed into the billing system
