Sewer

The Rockland sewage treatment facility consists of a 3 cell biological treatment area, located west and north of the city.  Historically, after treatment, the affluent was discharged into Rock Creek.  The city now has a 10 million gallon storage containment pond that holds the formerly discharged affluent and uses it to irrigate crops for non-human consumption.  This is a win-win situation for the community because it saves discharging into a waterway, protecting our surface water from possibility of contamination, but also provides a monetary return allowing for lower sewer rates.
