Southborough explores golf course irrigation using treated wastewater for sustainability

The Southborough Conservation Commission met on May 22, 2025, to discuss the potential development of a wastewater treatment plant, a project that could significantly impact the community's economic health and environmental sustainability. The meeting featured a briefing from representatives of Sudbury Valley Trustees (SVT) and town officials, who outlined preliminary ideas for utilizing treated wastewater to irrigate the town's golf course.

Currently, Southborough lacks a wastewater treatment facility, a decision made decades ago when the town was concerned about population growth. However, with the town now exceeding 10,000 residents, officials believe that establishing a treatment plant is crucial for future development, particularly along Route 9. The proposal includes using treated wastewater for irrigation, which is a common practice in areas facing water scarcity.

The discussion highlighted that treated wastewater could replace drinking water for irrigation during the growing season, with plans to discharge excess water into the ground during off-peak times. This approach not only conserves drinking water but also promotes sustainable practices by reusing a valuable resource. The officials emphasized that these ideas are still in the early stages, with no final decisions made yet.

Concerns were raised regarding the safety of using treated wastewater, particularly regarding potential contamination. Officials reassured attendees that modern treatment facilities are rigorously monitored and adhere to strict environmental regulations. They also noted that any implementation would require extensive permitting and technical assessments to ensure safety and compliance with environmental standards.

Another point of discussion was the conservation restrictions (CR) associated with the golf course property, which limit its use to specific facilities. This raises questions about the feasibility of the proposed irrigation system and whether it aligns with the CR's stipulations. The commission acknowledged the need for further legal consultation to clarify these restrictions.

As the conversation progressed, it became clear that while the idea of using treated wastewater for irrigation presents several benefits, including environmental sustainability and economic viability, it also poses challenges that need careful consideration. The commission plans to continue exploring this initiative, engaging with stakeholders, and assessing other potential sites for wastewater discharge.

In conclusion, the meeting underscored the importance of balancing community needs with environmental stewardship. As Southborough moves forward with its wastewater study, residents can expect ongoing discussions about how best to implement solutions that support both the town's growth and its natural resources.
