New Jersey’s Water Quality [Achievement] Act

Former Mayor Lester Taylor, talking about East Orange’s reinvestment in its water system

The Garden State has quietly enacted a law that could transform water infrastructure in America.

Signed during Governor Christie’s waning days in office, New Jersey’s 2017 Water Quality Accountability Act (WQAA) introduced a series regulations requiring local water utilities to develop asset management plans, report on infrastructure conditions, and reinvestment adequately in their systems. For outsiders to the water sector, the WQAA might seem like a set of narrow, technocratic rules. But it’s really much, much more—not because of the rules themselves, but because the data that the rules will generate can change the way that people think about the crucial but unseen systems that sustain American cities.

A renaissance artifact in a German village helps explain why.

Drinking water and credit claiming

While Governor Christie was signing the WQAA, my wife and I were sightseeing in Germany. There we visited Wertheim, a small town nestled on the banks of a river. Right in the village square stands the Engelsbrunnen, or “Angel’s Well.” The village has been there since the 8th century, but this well was constructed in 1574. The well’s construction transformed life in the village—before the well was built, villagers had to walk 100 yards down to the river to fetch water.

16th-century state-of-the-art urban water supply

But the really interesting thing about this well is the structure that surrounds it. This wasn’t just a utilitarian bit of public works—it was, and remains, a jewel at the heart of the village. It’s named for the twin angel sculpture at the top of the structure, but what really stands out is the sculpture in front, at eye-level:

Hey there villager! Enjoying that clean, convenient water?

That is the mayor of Wertheim in 1574. He didn’t just want his people to have water, he wanted them to know who delivered it. And every day, when the villagers filled their pails of water, they’d do so standing face to face with the image of the mayor who built it. For Wertheim, the well was a major improvement in quality-of-life. For the Mayor, the Engelsbrunnen was what political scientists call a credit-claiming opportunity.

Politicians then, like politicians now, like to claim credit for good things. In the 19th and early 20th centuries, modern drinking water systems provided politicians with ample credit-claiming opportunities. And with good reason! Drinking water systems are amazing! They are the everyday miracles of the modern age.

Blame avoidance and infrastructure neglect

Unfortunately the politics of American drinking water have changed. For decades Americans have had the luxury of taking drinking water for granted. Maintaining or upgrading drinking water systems doesn’t offer the same kind of credit-claiming opportunity as building them.

When the public takes water for granted, leaders fear anger over rate increases, which they must balance against the fear of a disaster. As National Association of Water Companies CEO Rob Powelson put it: “No president or governor wants to have a Flint Water Crisis on their hands.”

That’s what political scientists call blame avoidance.

The thing is, blame-avoidance isn’t a very good motivator for infrastructure investment. If my political goal is to avoid blame for a disaster, then my tradeoff is tax or rate increases today vs. the risk of disaster on my watch. Rate increases today are immediately visible and unpopular; to politicians, the risk of disaster can feel remote—my successor’s problem, not mine.

From fear of failure to expectation of excellence

That’s where New Jersey’s WQAA has the chance to transform the politics of drinking water. With the data generated under this new law, researchers will be able to trace the full nexus of the relationships between costs, water quality, system performance, and capital reinvestment. We’ll be able to show how to maintain affordability while also maintaining public health and economic prosperity.

But most importantly, all that analysis can make water infrastructure a credit-claiming opportunity again. We’ll be able to quantify the health and environmental benefits that come from water infrastructure, and so give leaders a reason to brag about their investments in these critical systems.

My only gripe with the WQAA is its name: the word “accountability” implies a threat of punishment for failure, rather than opportunity for success. With due respect to the NJ legislature I’d have preferred a different name: the Water Quality Accountability Achievement Act. Water system maintenance, reinvestment, and public reporting on performance shouldn’t be feared as a cause of punishment, but embraced as a chance to celebrate excellence.

Hats off to New Jersey’s water leaders for seizing this moment and blazing a promising trail. New Jersey’s WQAA gives water sector leaders the chance to make this moment an inflection point: the time when water stopped being an afterthought and became a core policy concern again; when the water sector turned away from fear of failure and back to visionary achievement.

 

 

 

Wholesale Savings

During California’s recent drought, the utilities that own their supply sources conserved more than the those that purchase water from wholesale suppliers

-Warning: this post contains hardcore wonkery-

A while ago I blogged about my ongoing work with Youlang Zhang and David Switzer on water conservation in California. The first of our studies is now published at Policy Studies Journal; more are on the way. There we saw that financial incentives and institutional politics led to the surprising result that private, for-profit companies out-conserved local government utilities during a recent drought.

But another interesting pattern emerged from that study: a significant difference in conservation between utilities that draw their water supplies from wholesale sources.

Where utilities get their water

The drinking water utilities that serve American communities get their water in one of three ways*:

1) Pumping groundwater from wells that tap underground aquifers;

2) Drawing surface water from lakes and rivers; or

3) Purchasing water from a wholesale water utility.

In the first two cases, local utilities own wells, surface water intakes, and treatment plants. About 29% of American utilities fall in the third category, getting their water through wholesalers. In these cases, the local utility owns a distribution and/or storage system, but the supply works and perhaps the treatment facilities belong to another utility. Sometimes these wholesale utilities have retail customers of their own, sometimes they are purely wholesale suppliers.

MWD supplies water for more than 19 million Californians

In California, more than a third (36%) of water systems get at least part of their water from a wholesale supplier. A handful of very large wholesale water suppliers like Metropolitan Water District, San Diego County Water Authority, and Santa Clara Valley Water District manage major supply works, and then sell water to cities, special districts, and investor-owned retail water utilities.

Spreading the risk

A major advantage of big wholesale water utilities is that they allow a region’s water supply to be managed holistically and comprehensively. Rather than individual communities competing and depleting water supplies, regional wholesalers can plan and balance water supply needs. From the local perspective, wholesale utilities help diversify supply and so guard against catastrophic supply shortages. They also allow communities across a region to pool their capital for greater efficiency. Together these features spread both supply risk and financial risk across many local utilities.

“Take-or-pay”

Sales agreements between retails and wholesalers vary widely across the country, so generalizing is difficult. But one common feature of wholesale contracts is the take-or-pay provision. Under take-or-pay arrangements, the wholesaler agrees to supply and the retailer agrees to purchase a fixed volume of water over a given period of time for a given price. If retail demand exceeds the contract volume, the retailer pays for more on a volumetric basis. If retailer demand falls short of the contracted volume, the take-or-pay provision requires the retailer to pay the wholesaler anyway, as if it had used the entire contract volume.†

In other words, under take-or-pay contracts, the retailer pays the wholesaler the same amount, even if the retailer uses far less water than the contracted volume.

Wholesale supply & the logic of conservation

Got all that? Still with me?

Here’s what it all means for conservation. Wholesale supply arrangements reduce supply risk and long-term financial risk to local utilities. Take-or-pay contracts make a lot of sense for long-term stability for supply systems that have high fixed costs.

But in the short-term, these wholesale arrangements create disincentives for retail conservation during a drought. Under wholesale agreements, short-term supply risk from drought is shifted from the local utility to the wholesaler: the wholesaler is legally responsible for maintaining adequate supply. Meanwhile, fixed take-or-pay contracts leave retailers on the hook for the same amount no matter how much water their customers actually buy. The retailer may suffer significant sales declines if it rains all summer, or if the state imposes drought restrictions, but the retailer still has to pay the wholesaler as if demand was normal.

Together, these factors create structural disincentives for emergency conservation for retail utilities under wholesale agreements.

Wholesale $avings

Does diluting risk also dilute conservation? As I explained in an earlier post, the recent drought in California prompted that state to impose conservation rules on retail water utilities from June 2015-May 2016. Each utility was assigned a specific conservation target and the state recorded overall conservation by each utility.

Did utilities that operate under wholesale supply arrangements perform differently from utilities that own their own supplies?

Our analysis of data from the drought mandate period is pretty striking. After accounting for a host of organizational and environmental conditions, we found that water systems that rely on wholesale water supplies were 42% less likely to meet state conservation standards, compared with systems that own their own supplies.

We also found that, after accounting for other factors, utilities under wholesale contracts conserved an average of 2.6% less each month relative to systems that use their own wells or surface water sources. In a state as large as California, this small percentage difference equates to tens of billions of gallons.

Follow the money

These patterns don’t prove that wholesale contracts caused California utilities to slack on conservation. But the data certainly align with the short-term incentives that wholesale supply arrangements create, and there aren’t other obvious reasons for the disparity. The lesson here is to pay close attention to wholesale contracts when setting conservation rules, so that conservation and financial incentives work in concert.

 

 

*Technically there are other sources, too—desalination and water reuse, for example–but they’re so rare that they don’t allow for much meaningful analysis.

 ”Take-or-pay” is a weird phrase, since there’s really no “or” to the arrangement. Seems like “fixed fee” is a more accurate label, but then I’m not a lawyer.

Water Cops

Many California communities restricted outdoor irrigation during the recent drought. Did enforcement matter?

Bad water boys, watchya gonna do when they come for you?

Faced with water scarcity, communities sometimes restrict residential outdoor water use, such as car washing and especially lawn/garden irrigation. These water restrictions are effective in driving water conservation, and many California communities adopted them during that state’s recent drought (I’ve blogged about them before). The severity of those restrictions varied considerably, with some utilities allowing unlimited irrigation, some allowing irrigation just one or two days per week, and a few banning outdoor irrigation altogether.

Enforcement of those restrictions was  up to individual utilities, and enforcement actions varied considerably. Youlang Zhang and I have been analyzing those enforcement actions and how they correlated with conservation outcomes; we’ll present our first results at the APSA Conference in Boston next week. How did California utilities enforce water restrictions? Did enforcement actions affect water consumption?

Avenues of enforcement

In July 2014 the SWRCB authorized local water utilities to impose fines of up to $500 a day for violating water restrictions and invited citizens to report violations of water use restrictions through online portals and telephone hotlines. After receiving complaints or observing violations, utilities proceeded with a series of escalating enforcement steps. The first is a follow-up action, an informal intervention that typically involves sharing information with the violator with a goal of compliance through education. The second step is a formal warning, where the utility informs the violator of regulations and potential penalties. The final step is a formal penalty and fine.

A different logic underlies each of these enforcement actions Follow-up actions convey information about public policies and community values, with the expectation that greater awareness will motivate conservation. Warnings threaten violators with punishment, and so raise the prospective cost of profligacy. Penalties punish past action in hope of deterring future behavior. Over the course of the drought local utilities issued hundreds of thousands of warnings and levied tens of thousands of penalties for violating water regulations.

Enforcement effects

We analyzed monthly data from California over the 32-month drought emergency period, looking for relationships between utilities’ enforcement actions and total conservation by those utilities. Basically we were asking: does past enforcement predict present conservation?

Initial results are fascinating. Informal follow-up actions and penalties had no statistically discernible relationship with conservation. Only warnings appear to be correlated with conservation. Here are the effects, plotted graphically:

Marginal effects of enforcement action on conservation

In substantive terms, these results indicate that 100 formal warnings results in about 0.1% greater conservation. Though these figures are small in percentage terms, they represent potentially large volumes of water. An average of 500 more warnings each month during the observation period would have reduced the state’s total water consumption by 29 billion gallons—enough to supply the City of San Francisco for 15 months.

So are penalties pointless?

Does that mean that penalties don’t work? Not necessarily. It’s likely that the positive effects of warnings depend on the threat of penalties. Also, a $500 penalty might be an insufficient incentive for conservation in utilities where penalties were imposed. If you’re a rich celebrity, you might not care about a $500 fine enough to stop wasting water. Without detailed data on individual violations (which we don’t have), it’s hard to say.

In any event, the effects of all enforcement actions were apparently short-lived. Enforcement actions were most influential early in the drought emergency, when climatic conditions were most severe. As the drought weakened, the influence of enforcement also declined. The effects of all three types of enforcement actions appear to be negligible in the long run.

Lessons for conservation

We need to do more work to make sure we have the analysis right and to tease out all of the temporal effects, but our findings to date suggest three preliminary takeaways:

  1. Formal warnings are most effective in driving overall conservation; and
  2. Warnings can lead to immediate conservation during an emergency; but
  3. Enforcement effects decline in the long run, and so probably don’t help promote conservation as a “way of life.”
