Aquarion says the goal is to improve drought resiliency.

Critics say Aquarion’s application to the Connecticut Department of Energy and Environmental Protection lacks adequate detail on the possible impacts to water quality, wildlife habitats, as well as impacts to the river, area wetlands, and nearby private wells.

At a meeting at Wilton Library Tuesday night, residents turned out in number, including Aleksandra Moch of Greenwich Conservation Commission, Marija Mikolajczak of Greenwich Conservation Advocates, and Elizabeth Dempsey of Conservation Coalition.

AquarionThought it wasn’t a public hearing, the public was allowed to share remarks on Aquarion‘s application. 

According to Good Morning Wilton, Aquarion officials said they were at the meeting voluntarily as a show of “transparency and openness” to explain to town residents their objectives and goals.

Dan Lawrence, the utility’s director of engineering and planning, said that the company had put together a mitigation plan to address impacts the proposal might have on surrounding ecology and neighboring wells.

Lawrence, quoted in Good Morning Wilton, said Tuesday night that having a local source in Wilton provides an opportunity for resiliency as an alternate source and gives the utility an opportunity to think about drought and the need for multiple sources.

The application uses research and a study Aquarion began in 1971, and conducted primarily in 1984 and 2013, to evaluate impacts of water withdrawal to the river and nearby wells and habitat.

Aquarion purchased a tract at 3 Cannon Road in Cannondale in 1981. The company installed the production well on the property in 1982 in order to provide an additional water supply for the system, but the well has only been used for testing purposes.

After the severe drought in 2016, Aquarion has been reviewing additional water resources.

The well in Wilton is located near Aquarion’s water mains, and they want to bring it online.

Less than three years ago, in 2016, a drought impacted area residents. At the time, the drought was so severe that Aquarion ran temporary, emergency water mains along the Merritt Parkway.

Good Morning Wilton quoted Lawrence saying the private wells in the surrounding 1,500 foot radius from Aquarion’s well draw water from well below the surface, in bedrock — except for one well at a nearby property on Danbury Road. He said the company is in discussions with the property owner about connecting them to the Aquarion system.

From Aquarion’s Application:

An excerpt from Aquarion Water Company’s (AWC’s) application to the Connecticut Department of Energy and Environmental Conservation (CT DEEP):

AWC’s 2006 Water Supply Plan indicates that the Southwest Fairfield County planning region (Greenwich, Stamford, Darien and New Canaan Systems) currently has a margin of safety of less than 15 percent.

This margin of safety deficit will be further exacerbated by the loss of safe yield in the Greenwich and Stamford system reservoirs as a result of the CT DEEP’s Streamflow Standards and Regulations.

AWC’s Water Supply Plan indicates that the long-term solution for additional supply in the Southwest Fairfield County region is to increase the capacity to transfer water from the Greater Bridgeport System.

This permit is being requested to augment the Greater Bridgeport System, which is utilized to address the margin of safety deficits for the Southwestern Fairfield County Planning Region. Although the water from the Cannondale Well will not increase the margin of safety significantly because of mitigation measures that will be implemented (discussed further in Attachment L [not found on the website]), it will provide AWC flexibility to more effectively and reliably move water throughout the Greater Bridgeport System and improve drought resiliency.

An added benefit of the permit may be the potential to utilize the Cannondale Well during the fall and winter months to increase the probability of reservoir refilling when increased releases are required from the Greater Bridgeport System reservoirs. This individual permit application is a request to operate the Cannondale Well at a maximum withdrawal rate of 1.0 million gallons per day (mgd).

Proposed construction activities include connecting the Cannondale Well to the existing pump house (via an underground main) and the construction of a small treatment facility to treat the discharge prior to entering the distribution system. The treatment facility will include chemical addition (chlorine, fluoride, corrosion inhibitor and pH adjustment), well controls and standby power.

Area Conservationists: Conserve Instead

The Norwalk River Watershed Association (NRWA) has questioned whether the well is necessary, or whether drought resilience could be met through conservation, infrastructure repairs, and other improvements.

“Aquarion Water Company applied for a permit in early October 2018 to pump 1 million gallons per day from a previously unused well next to the Norwalk River in the Cannondale area of Wilton, reducing the flow of the river by up to 10% of the previous 7-day average for 25 years.” — statement on NRWA website

Though the meeting was not a formal hearing, members of the public were allowed to speak, including Greenwich resident Elizabeth Dempsey.

Reached by email on Wednesday, Dempsey said, “Unlike true drought issues, as the western states are facing, this application is not about drinking water and taking showers. The vast majority of water issues in southwest Connecticut are in the summer where when millions of gallons every day are used for our yards and golf courses.”

“This usage, which in Greenwich is already being managed, does not justify a diversion that scientists say will severely degrade an important waterway,” Dempsey added.

Dempsey said the Norwalk River is enjoyed by seven towns in Connecticut and is vital for recreation and for wildlife, fishermen, and the shellfish industry. “All of those stakeholders in turn contribute to the health of Long Island Sound, our most vital asset,” she said.

In an email on Wednesday, Marija Mikolajczak of Greenwich said, “During the drought, Greenwich dramatically reduced its daily water usage from 32 million gallons per day peak summer usage to 5 million gallons per day after an outdoor irrigation ban was implemented, indicating that the overwhelming use of water was going to outdoor uses.”

Mikolajczak and Dempsey both said Greenwich does not need the water, and would be better served by dramatically increasing water conservation.

On Tuesday night in Wilton, Dempsey shared a statement from Allison Walsh, a Greenwich RTM member who is an environmental lawyer:

This diversion application is made pursuant to CT Gen. Statutes 22a-368. It is governed by the CT Water Diversion Policy Act, which stated:

In recognition that the waters of Connecticut are a precious, finite and invaluable resource upon which there is an ever increasing demand for present, new and competing uses; and in further recognition that an adequate supply of water for domestic, agricultural, industrial and recreational use and for fish and wildlife is essential to the health, safety and welfare of the people of Connecticut, it is found and declared that diversion of the waters of the state shall be permitted only when such diversion is found to be necessary, is compatible with long-range water resource planning, proper management and use of the water resources of Connecticut and is consistent with Connecticut’s policy of protecting its citizens against harmful interstate diversions and that therefore the necessity and public interest for sections 22a-365 to 22a-378, inclusive, and the protection of the water resources of the state is declared a matter of legislative determination. (Connecticut General Statutes 22a-366 – Legislative findings)

The legislature’s intent to prevent diversions unless absolutely necessary AND compatible with long range stewardship of these resources is crystal clear.

Aquarion’s requested diversion does not meet these applicable standards:  it is unnecessary and wholly inconsistent with proper management of our water resources and long range water resource planning.

The DEEP must protect the Norwalk River and not permit the diversion being sought. As others have said, it is already a stressed resources that fails to meet standards even without the massive diversion of 1 million gallons of water each day. Southwest Fairfield county does not need more water; we need to use less water and use it better, recycling it.

We are a resource hungry county and Eversource/Aquarion, as steward of our energy and water usage, should be promoting water conservation, use of gray water recycling systems, and less energy usage, rather than taking from natural resources that need to be preserved, not depleted.
