Sanitary Sewer Maintenance

Press Enter to show all options, press Tab go to next option

Maintenance of the sanitary sewer collection system is provided crews from the Infrastructure Maintenance Division and the Water Reclamation Plant. Maintenance is performed to provide free-flow of the wastewater through the system and to prevent blockages that can cause back-ups  and sanitary sewer overflows. These back ups and overflows can be a health risk, in addition to being an inconvenience to the business/home-owner.
