A plan to extend Mercer borough's sewer system into Coolspring Township may be like the Energizer bunny: it could keep going and going.

As borough council works toward approving an agreement between the two municipalities to allow 80 more businesses and residences in Coolspring Township hook onto Mercer's sewage system, they say it could be the basis for other intermunicipal agreements.

Discussion about the possibilities arose when council entertained a request by an East Lackawannock Township business to hook into the borough's sewerage. Though council decided to table that request for now, plans to partner with adjoining townships, such as East Lackawannock and Findley, for those very same water expansion requests could happen in the next couple of years.

"It would be the basis of any agreement we have with any township," council president John G. "Jerry" Johnson said of the pending agreement with Coolspring Township.

Though Coolspring and the borough already had an agreement to allow approximately 55 township businesses and residences have borough sewer services, the revised agreement will allow approximately 80 more to hook on around U.S. Route 19 and includes a mobile home park.
