Dignitaries dedicate North Windham Wastewater Treatment Plant

By Ed Pierce

It’s been said that success in life is about project management in determining deliverables, making milestones, and always pursuing the critical path. For years, the Town of Windham has sought to find a solution to effective wastewater treatment and on Oct. 8, all those efforts were achieved with the dedication of the new North Windham Wastewater Treatment Plant.

With U.S. Senator Susan Collins of Maine on hand to cut the ribbon marking the new facility becoming fully operational on the grounds of Manchester School, Windham Town Council members and representatives of the Portland Water District and RSU 14 spoke about the collaboration it took to bring the $48 million project to fruition at no expense to taxpayers.

After decades of proposals, studies, and rejections from voters at the ballot box, Windham residents resoundingly approved sewer and wastewater treatment project for North Windham in a special referendum in June 2022. Partnering with the Portland Water District and RSU 14 to create the massive infrastructure project, the Windham Town Council covered the remaining costs for the initiative through a combination of grant funding, a $38.9 million award by the Maine Department of Environmental Protection, and North Windham TIF funding supported by North Windham businesses.

Now completed, the new wastewater treatment facility will address environmental issues in North Windham by removing 25,000 pounds of nitrogen and phosphorus pollutants each year being dumped by septic systems into the aquifer and watershed. The installation of sewers is expected to stimulate significant economic growth in Windham and lead to development in the area by industries and businesses not willing to locate here because of associated septic system issues and costs.

Through an agreement between RSU 14 and the Town of Windham, in exchange for locating the new wastewater treatment site at Manchester school, the town built four new playing fields for youth sports at the school.

The new Windham Wastewater Treatment facility uses Membrane Bio-Reactor technology with innovative drip dispersal and will be the first system to use drip dispersal of this scale in Maine. This technology is designed to improve the quality of local groundwater and local waterways, and was selected for its reliability, flexibility, and cost effectiveness.

Portland Water District officials say that the facility will clean and filter community wastewater that is currently being discharged untreated into septic systems. The cleaned, high-quality water, which is extremely low in nitrogen and phosphorus, will be released into an advanced drip dispersal system that will be 2 feet underneath the new athletic fields at Manchester School. They say the sandy soils native to the area are ideal for this system.

Because of the lack of an effective sewer system in North Windham, over the years contaminants have continued to pollute the aquifer, threatening surrounding ponds and lakes, and stifling economic growth. For the past two decades increasing nitrate levels have been observed in the underlying aquifer that threatened local water resources including Sebago Lake. Current levels of nitrates in the ground water have exceeded drinking water standards and septic system pollution entering the aquifer directly impacts surrounding valuable water resources. This new wastewater treatment plant addresses the issue before the problem escalated and became irreversible.

Speakers at the dedication included Senator Collins; Windham Town Council Chair Mark Morrison; RSU 14 Schools Superintendent Christopher Howell; Windham Town Manager Robert Burns; Maine DEP Water Quality Division Director Gregg Wood; Bill Lunt of the Portland Water District Board of Trustees; and Portland Water District General Manager Scott Firmin.

Collins said she was surprised to learn that Windham did not have an existing sewer system but praised everyone who worked diligently to make this project a reality.

“I was shocked that an area this populated did not have a wastewater treatment facility,” she said. “It was essential that we help.”

Collins was able to obtain $2 million from Congress to contribute toward the project.

“It has the smallest carbon footprint, and this innovative technology will serve as a model for other communities in Maine,” she said.

The project fits with an upcoming MaineDOT project for Route 302 redevelopment in Windham, the senator said.

“The two projects complement each other,” Collins said. “The vision of community leaders and citizens is truly impressive.”

Funding to support the Windham Wastewater Project included a $38.9 million Clean Water State Revolving Loan Fund Award; a $3.25 million SRF Debt Forgiveness Grant, $1.7 million in American Rescue Plan Funds allocated to the town, $2 million in Congressional Direct Spending sponsored by Senators Collins and King, and $1.5 million from Cumberland County Government. <
