Stormwater

Welcome to the Town of Merrimack Stormwater Page

National Septic Smart Week: September 19 to September 23

Tip 1: Just because something says its “flushable” doesn’t necessarily mean it’s safe for your septic system or the Town Municipal Sewerage System. Only toilet paper and human waste should be flushed down your toilet. Learn more here: https://getpumpednh.com #SepticSmartWeek #GetPumpedNH  or https://www.youtube.com/watch?v=mcYAubOSEvc

TIP 2:  Getting your septic system pumped doesn’t just help to keep it functioning properly. It also helps your community stay safe by keeping waste water out of local waterbodies. Learn more here https://getpumpednh.com or https://www.youtube.com/watch?v=-nXw5wsRJxY

TIP 3:  Did you know that the placement of trees and shrubs on your lawn can affect your septic system?  https://www.youtube.com/watch?v=Q4bTQ0PQiJA

TIP 4:  Water efficiency goes a long way when it comes to your septic system. Small leaks could mean big problems!
