Installment 3: Financing Water Conservation and Efficiency
As the debate over Prop 6 played out, many advocates
highlighted the fact that the underlying legislation, HB
4, provides that a certain percentage of funding should be dedicated to
water conservation and reuse. The specific
terms are important. HB 4 creates
section 15. 434(b) of the Texas Water Code, as follows (emphasis added):
Section 15.435 that are for:
(A)AArural political subdivisions as defined by
Section 15.992; or
(B)AAagricultural water conservation; and
(2)AA20 percent to support projects described by Section 15.435, including agricultural irrigation projects that are designed for water conservation or reuse.
Because the TWDB already has a program for agricultural
conservation loans, the use
of Prop 6 funds through SWIFT for those activities should be more
straightforward. The 2012 State Water
Plan projects significant needs for agricultural water conservation. For example, Region M projects that $ 132
million would be needed to conserve about 140,000 acre-feet/year in agriculture
by 2060. Region O projects a need to
invest $ 346 million in
agricultural efficiency measures to save 480,000 acre-feet per year, helping to
reduce pressure on the dwindling Ogallala aquifer. Given these needs and the
issues with financing customer-side efficiency improvements at the municipal
level, it may be that most of the conservation funding through SWIFT goes to
agricultural efficiency projects. (It is important to note that agricultural
efficiency programs don’t necessarily make more water available for other uses,
as farmers often use the water saved to expand crop production. However, there
are examples of arrangements in which water efficiency improvements on the farm
have yielded water for municipal or environmental uses.)
Nevertheless, municipal conservation is a vital strategy for
Texas to balance growth with limited water supply. The remainder of this post looks at what
role, if any, Prop 6 might play to advance this strategy.
Debt-financing
municipal conservation measures
The first question is why municipal water systems would choose to debt-finance water efficiency improvements for their customers?
Water conservation is actually a source of supply, just like
a reservoir or a desalination plant. The redefinition of water conservation
from a demand tool to a supply source was a major paradigm shift for water
providers, but is now commonly understood. Investments in water conservation
strategies with a clearly defined yield and lifetime can be debt-financed, and
repaid through revenue raised from a water suppliers’ customer payments, just
as they would pay back costs for any other water supply investment.
It appears that the only source of municipal water
conservation to which the Board has provided financial assistance in the past
is the repair of leaky distribution systems—the aging pipes that move water
from the source to the customer. The amount of water lost in transport from
source to user can be significant. A 2010 survey by the Texas Water Development
Board found that, on average nearly 15% of
water treated and sent through municipal systems is lost before ever reaching a
customer (based on 1,900 systems reporting data) Small systems serving 10,000 customers or
less averaged about 20% total water loss, and large systems with 100,000
customers or more averaged 15%.
Because the replacement of a distribution system is an
investment in the water system’s own assets, it is a perfectly acceptable use
of debt funds. Thus, reducing system
water loss should be a desirable and authorized use of the SWIFT funds.
However, there are other municipal conservation programs
aimed at individual water customers that can provide a reliable source of water
supply. The most reliable of these
“customer-side” approaches are those that replace physical systems, such as
programs that provide rebates or other incentives for replacement of
inefficient toilets or water boilers or for replacement of water-intensive
landscaping with water-efficient landscaping.
These types of programs generally are more reliable in terms
of supply than those that rely on changes in customer behavior (changes which
may or may not be permanent and which are often influenced by perceptions of
immediate drought).
Through a a combination of appliance retrofits and lawn
buy-back programs, Las Vegas has saved over 59.3 billion gallons of water since
1999. The city has spent $200 million to
replace more
than 150 million
square feet
of turf lawn
over the past decade, with long-term water savings guaranteed by covenants
ensuring that homeowners will not reinstall lawn they were paid to remove
unless they repay their rebate. Recently,
Austin Water announced it was launching its own lawn
buy-back program.
Debt-backed capital investment programs allow water
utilities to mobilize far more capital today than cash-backed capital programs.
(For more explanation of the debt-financing envisioned by SWIFT, including a
glossary of terms, see Installment
1 in this blog series). The benefit
of debt-financing is that water systems can borrow the money for what is needed
today, with future repayment backed by a pledge of future customer revenues. In
comparison, cash spent today must be available today. Since water systems raise
their cash from customer payments, a cash-financed program typically means
higher rates today than a debt-backed program. As a result, debt-financed
programs allow water systems to smooth the increase in customers’ rates.
Debt cannot be used for behavior change programs—the debt
issued for a capital program must be used to finance the construction,
acquisition or improvement of capital assets. It cannot be used for operations
and maintenance (for example, paying the energy bills for a water treatment
plant) or for public outreach programs (for example, media campaigns to educate
water users about conservation). These aren’t rules set in Texas, they are
rules set by the Governmental Accounting Standards Board, the entity that
defines accounting standards for the municipal bond market in which the Texas
Water Development Board participates.
But efficiency programs with a defined water yield are an
investment in a capital asset—water supply—and should thus qualify for debt
financing. And, in fact, there are water systems that use bond proceeds to
finance customer efficiency programs. Seattle Public Utilities has used debt
funds to finance the retrofitting of toilets and other water-using devices with
low-flow replacements. In Seattle what
made this possible was defining the “asset” being financed not as toilets, but as
the long-term water savings gained by toilet retrofits.
The potential for water efficiency investments on customers’
property does not end with toilets or turf grass. Institutional irrigation
systems, industrial machinery, any physical water distribution or water-using
device with a long lifetime can be a source of long-term water savings, and therefore
supply. And Texas is uniquely positioned to unlock the water savings in its
industrial, commercial and institutional sectors with the passage last session
of the Property Assessed Clean Energy Act.
This new law permits municipalities to use bonds to finance
customer loan programs for energy and water conservation purposes,
including water conservation systems, high efficiency irrigation equipment,
on-site improvements to use municipal reclaimed water, and more. This type of bond (called a PACE bond) is
repaid through tax assessments that remain attached to the property no matter
who the future owner may be. The PACE bond concept holds significant potential
for funding a transformation in the water intensity of Texas’ economy..
So, if it is desirable to pursue a large-scale customer
efficiency program (and if such approaches are included in the state water
plan), and if debt financing would make it easier to do that, SWIFT funds would
be made available for that purpose, right? Not necessarily.
Public Purpose v.
Private Benefit
The ability to use SWIFT funds for these customer-side efficiency improvements largely comes down to whether programs that improve an asset owned by a private citizen or a business can be financed with public monies.
Texas, like most states, has a Constitutional prohibition
against the use of public funds for private benefit, something called “the gift
clause.” As discussed in this
post by the Energy Center at the University of Texas School of Law, Article
III, Sec. 52(a) of the Texas Constitution prohibits the state from lending
credit or granting money to “any individual, association or corporation
whatsoever,” a prohibition that can be relaxed for activities that would enable
a public purpose.
Defining a public purpose is where the complications begin, however. In many instances, legislators have opted to explicitly authorize the use of state financing for specific activities rather than leave to the courts what might be reasonably construed to serve a public purpose. Such is the case with toll roads, for which purpose the state’s credit has been authorized in numerous amendments.
In fact, one piece of legislation from the 2013 session
attempted to do just that for water conservation. House
Joint Resolution 142, filed by Chairman Alan
Ritter (the House sponsor of H.B. 4), would have expressly defined water
conservation as a public purpose eligible for state funding. As filed, HJR 142 provided that “[n]otwithstanding any other provision of this constitution, the
legislature may provide for the creation of programs and the making of loans
and grants of public money, other than money otherwise dedicated by this
constitution to use for a different purpose, for the public purpose of water
conservation.”
Unfortunately, H.J.R. 142 did not advance through the
legislature, leaving the question of whether the Board or other state agencies
can lend their credit for the public purpose of municipal water conservation
open to the determination of the Texas Water Development Board and for
potential challenge in the courts.
Texas does have some history of using state credit for
private benefit that serves a public purpose. One example is the use of TWDB
funds to address the lack of safe drinking water and sewage treatment in
colonias along the Mexican border. (The following is adapted from email
correspondence with former bond counsel to the TWDB.) In the 1990s, the Board
deliberated whether the gift clause prohibited it from making financing
available for connections of homes water and wastewater utilities. Ultimately,
the Board decided that as long as four tests were met, use of public funds
would not constitute an unlawful gift or lending of credit. The four tests
were:
- Are there sufficient
controls on the expenditure to ensure that the public purpose will be
carried out?
- Is the public protected in
the use of public funds to accomplish the intended result?
- Has the political
subdivision making the expenditure adequately considered this use of
funds?
If TWDB defines water conservation as a public purpose in
its prioritization and rulemaking processes, and if it ensures sufficient
controls over the use of funds to achieve that purpose (such as audits of water
savings, installation of water-saving devices and deed restrictions or other
assurances for their longevity), the TWDB would likely have sufficient grounds
to include customer-side municipal water conservation programs as eligible for
SWIFT funds. Using SWIFT funding for
customer-side municipal water efficiency programs could help ramp up this
cost-effective water supply strategy in communities across the state.
Effective use of the Prop 6 conservation earmark to include
these programs will require a change in practice and perspective and clear
rules from the TWDB, (and it will require that such programs be explicitly
included as strategies or projects in the state water plan).
