Work to bring the town’s wastewater treatment plant into compliance with new phosphorus discharge rules is estimated to cost $47 million.Phosphorus is considered an environmental hazard because it causes algae bloom, which depletes oxygen in water bodies and poses a threat to wildlife. The town is eligible to receive just under $20 million in state and federal grant funding for the work. The rest of the cost would be paid for primarily through water and sewer rate increases.
