We’re here for you. It is our privilege to be Lowell’s steward of the Merrimack River, and we work every day to improve our capacity to protect the environmental and recreational benefits of the fourth largest river in New England. Below you will find resources to better understand our National Pollutant Discharge Elimination System (NPDES) permit requirements, how to obtain a permit to discharge to our collection system (industrial/commercial), how to connect to our residential sewers, obtain a review of your stormwater management plan, and more. 

Please let us know if you have questions, or if you can think of a way we can serve you better!
