Protecting a National Park By Designing a Sanitary Sewer System

Challenge

Aging septic systems on properties near Voyageurs National Park were failing at an alarming rate. The septic systems were failing, in part, to difficult topography, high bedrock and high water tables.

Solution

A sanitary sewer system connected to a series of grinder stations and pump, which were used to transfer waste from individual properties to a main line dug into the bedrock. The new system connects to a wastewater treatment plant 15 miles away.
