Collection System

This map of the Wastewater Reclamation Authority (WRA) conveyance system represents the sanitary sewers that have been in service since the end of 2013. The WRA conveyance system extends into Dallas, Polk and Warren Counties with approximately 125 miles of sanitary sewer with pipe sizes up to 144 inches in diameter.


The system directs flows to the Wastewater Reclamation Facility under normal flow conditions. Under periods of high flows, equalization basins throughout the system are utilized to temporarily store flows which are in excess of what can be treated at the Wastewater Reclamation Facility. Once the flows return to normal, the equalization basins are then drained back into the system and the stored flows are treated. 

Flow Volumes

Flow volumes are monitored by various flow meters throughout the conveyance system. These volumes are used to allocate operating costs to the different communities that make up the WRA and are also used for operational purposes. 

Locations & Flow Information

Information on flow meter locations and flows at each flow meter can be viewed by visiting the Telogers website. To acquire a username and password for the flow monitoring website please call 515-323-8135.
