Sewer Division


Maintenance of the city’s sewer system and the proper processing of wastewater is provided through the Sewer Division.  Management of wastewater is vital for the health of the community and a sound environment. 

Collection System

In Dallas, wastewater from more than 15,000 people and numerous businesses travels through more than 66 miles of sewer pipes to the Water Reclamation Facility (WRF).  The Division maintains these lines through routine maintenance and annual pipe replacement projects.  


The WRF is managed under a contract with Jacobs Engineering with oversight by the Engineering and Environmental Services Division. 

Permits and Programs

The Engineering Division provides support by overseeing numerous state permits required for municipal systems as well as handling the administration and operation of the City’s Industrial Pretreatment Program; Inflow and Infiltration (I & I) Reduction Program; Willamette Total Maximum Daily Load (TMDL) Program; and the Capacity, Management, Operations, and Maintenance (CMOM) plan.
