Waukesha wins Wisconsin DNR support in bid to export water from Great Lakes basin

Much of Waukesha’s municipal drinking-water supply is drawn from deep, sandstone aquifers where the water unfortunately contains high levels of radium, a carcinogen that is difficult to remove.

The Waukesha Water Utility’s campaign to stick a giant straw into Lake Michigan has won a critical endorsement from Wisconsin’s Department of Natural Resources, hastening the first critical test of a 2008 ban on exporting water from the Great Lakes to places beyond their basin.

It’s hardly a new idea; Waukesha has had its eye on the lake for decades. And it’s not that the city wants a whole lot of water – perhaps 10.1 million gallons a day, on average, by mid-century. It will even give most of it back, treated.

But if it succeeds in staking this claim, based on a narrow-sounding exception in the rule against out-of-basin diversions, Waukesha will become the first municipality entirely outside the basin to be granted rights to Great Lakes water. And that will set a precedent that hundreds of other communities across eight states and two Canadian provinces could point to and say:

Hey, what about us?

The surface of the Waukesha case is simple and even sympathetic. Much of the municipal drinking-water supply is drawn from deep, sandstone aquifers where the water unfortunately contains high levels of radium, a carcinogen that is difficult to remove.

The city has been under state or federal orders to bring its drinking water into compliance with safety standards on radium since at least 2003, and since 2006 it has been missing deadlines for doing so.

Indeed, Waukesha has already said it will miss the current deadline, which is June 2018, even if it wins the necessary approvals to build the new system, which would take some time and cost more than $200 million.

Approval might take some time, too: Signoff is required from each of the eight states of the Great Lakes Compact – Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania and Wisconsin – and also, practically speaking, from the provinces of Ontario and Quebec, which have considerable influence but no actual vote in the matter.

Limits on diversion

Out-of-basin transfers have become difficult since 1986, when U.S. law required replacement of diverted water, and almost impossible since Congress approved the compact and its new rules in 2008.

However, those rules allow an exception to be made for a community that meets certain tests, the chief ones being these:

  • It must be situated in a county that is at least partly within the basin – the so-called “straddling” requirement.
  • It must lack “reasonable” means of meeting demand for potable water by tapping other sources, or by cutting consumption through conservation measures.
  • It must agree to return to the basin as much treated water as it takes out, less an allowance for certain “consumptive” uses like beverage bottling and evaporation from lawn sprinklers.
  • The overall plan must not endanger water quality or quantity or ecosystem integrity in the Great Lakes basin.

Although Waukesha’s contentions on all but the first point are challenged by opponents of the diversion, last Thursday’s DNR announcement gives it Wisconsin’s tentative blessing on all points. Also, an official conclusion that tapping available alternatives (inland lakes, additional shallow aquifers) could carry worse environmental impacts.

Why the basin matters

As every Minnesota schoolchild learns, the Great Lakes are the world’s largest body of interconnected lakes and hold one-fifth of the world’s surface freshwater, by volume. Far fewer folks understand that the lakes occupy a basin that, relative to their surface area, is quite small.

For instance, in the Milwaukee/Waukesha region the “subcontinental divide” that forms the basin boundary, sending this raindrop to Lake Michigan and that one toward the Mississippi River, is within a dozen miles of the lake’s shoreline in places; Waukesha is about a mile and a half to the west of the boundary.

In this map showing counties in and bordering the Great Lakes’ basins, Waukesha County is highlighted in orange.

To understand why this matters, picture your average large lake as an ounce of water puddled in the middle of a dinner plate. By comparison, the Great Lakes are an ounce of water in a shot glass.

Imagine putting both “basins” on the deck in a gentle rain and you can see the problem: The shot glass captures far less precipitation relative to surface area (or volume),  which means that whatever water is removed takes far longer to replace.

That limiting reality hasn’t stopped decades of talk – mostly fanciful, given the huge construction and/or transport costs – of sending Great Lakes water to parched California, or to profligate Kuwait.

But it has moved policymakers and governments to draw a line against diversions across the basin boundary – the line that Waukesha now proposes to test with its claim of exceptionality.

Interestingly, the line’s particulars may have been drawn with just this battle in mind. Five years ago, in an interview with the Great Lakes Echo, Noah Hall of the Wayne State University Law school and the Great Lakes Law blog said:

Waukesha, Waukesha. When we were drafting and negotiating the Compact, it was very clear that if the Compact made it impossible for Waukesha to divert water it wasn’t going to pass; and if it made it too easy it wasn’t going to pass.

What people wanted was exactly what I think we got: a very, very little open window to give Waukesha some possibility of getting a Great Lakes diversion, but it won’t be easy and it shouldn’t be easy.

Pugnacious, irascible, unreasonable

Wisconsin DNR
Waukesha proposes to receive Lake Michigan water through a new pipeline from the city of Oak Creek, which already gets its water from the lake, and return treated wastewater via the Root River.

As Peter Annin notes in his fine book, “The Great Lakes Water Wars,” Waukesha has been displaying a “pugnacious, irascible and unreasonable” stance on its water needs, and a covetous eye for Lake Michigan, for decades — starting with a bid to share in Chicago’s withdrawals.

When Congress voted in 1986 to require that out-of-basin transfers be returned volume for volume, Waukesha sought to be exempted for withdrawals of 20 million gallons daily, about twice what it now seeks. When the U.S. Environmental Protection Agency ordered it to meet radium standards, it sued first, then settled.

No wonder there’s a certain level of suspicion about the current proposal, the supposed lack of alternatives and the DNR’s supportive findings.

A coalition of regional environmental groups told the Milwaukee Journal Sentinel that they will commission a new engineering analysis to challenge Waukesha’s bid in a public-comment period that runs through Aug. 28.

The arguments are likely to parallel those raised in a 2013 analysis funded by the National Wildlife Federation and prepared by Jim Nichols, a hydrogeologist and former director of the U.S. Geological Survey’s Michigan Water Science Center. Among its points:

  • Waukesha’s forecasts of future demand reflect a dramatic planned expansion of the water utility’s service area to suburbs that are not now on city water (reported elsewhere as an 80 percent increase in system size).
  • The forecasts assume residential usage rates that are higher than any reported in Waukesha for the previous 10 years, and do not reflect historical trends of declining residential usage that other U.S. cities have experienced.
  • While Waukesha has had some success with conservation measures aimed at industrial users, and has reduced residential consumption somewhat with lawn-watering restrictions and unit pricing that rises with consumption, much more water could be saved with, say, an aggressive program of conversion to low-flow toilets.
  • Known groundwater resources, both the aquifers already being pumped for the Waukesha system and others not yet in use, are sufficient to meet predicted demand, and without adverse impact on waters in the Great Lakes basin (although impacts on other Wisconsin waters are less clear, because of flaws in modeling used to make Waukesha’s case).

What’s next

The Wisconsin DNR expects to reach its final decisions in September. I asked the Minnesota DNR how it would handle the referral under the Compact and Julie Ekman, manager of the conservation assistance and regulation section, replied:

We have not yet established how we will handle this. Although, I can envision that we will connect with our sister agencies to assess their interest in reviewing the project.

We are upstream from this project, so there won’t be physical impacts to the Great Lakes basin that lies within Minnesota. This fact might have implications for the extent of review conducted. But I can’t say that for sure yet.

    Waukesha is Scott Walkers base

    Does this surprise anyone?

    Waukesha’s Application is Baseless

    As a Waukesha resident, I have a great interest in this topic.

    This a good topical piece. But, is not accurate to illustrate that because Waukesha draws water with radium from the deep aquifer, it has no other options except a Lake Michigan Diversion Exception.

    Nothing could be further from the truth.

    Waukesha is already filtering radium from some of the deep aquifer wells as a condition in a judgement and stipulation court order. If the application fails, they can install filters on the remaining wells to satisfy the June 2018 deadline on the radium issue. Even if the application is approved, they cannot meet the court ordered deadline without filters because the timetable to complete construction is now 2020. Waukesha has said they will will request an extension. That will not happen. This was the final decision after fighting the issue since 1987.

    Considering that the deep aquifer has risen 100 feet in the last 15 years, is 1800 feet deep and has dropped at is worst point in 1998 to 450 feet, the application is baseless. Waukesha is not without a long term source of water. The deep aquifer has shown that it has the potential for sustainable for growth through 2050 and there is no scientific modeling study, based on it’s recovery since 2000, to suggest otherwise.

    The cost of a wait-and-see approach is pocket change to the utility customers. There is no shortage of water unless developers and local officials create it.

    Walker’s Waukesha

    Thanks Ron. Great article again. You’re the best source for environmental news. Scott Walker is from Waukesha. He’s proposed eliminating the Wisconsin DNR. The legislature has voted to gut the DNR’s regulatory oversight in an effort to push through an iron ore mine near pristine land in Northern Wisconsin that would pollute the Bad Medicine Band’s reservation. When will Wisconsin wake up to the harm their politicians are doing to them and their great state?
