Sewer

The Boise sewer system is a collection of more than 782 miles of pipes that weave underneath the City.  Along with regular system maintenance, Public Works makes major repairs and is in charge of designing the system. Since 1985, Public Works has also regulated industrial and commercial wastewater discharges into the sewer system through its EPA-approved Pretreatment program.  In addition, Public Works also sets the sewer rates for residential and commercial users and administers sewer billing.
