Projects

The Broken Arrow Municipal Authority (Authority) located in Tulsa County serves 36,621 sewer customers and 38,129 water customers. According to the 2010 U.S Census the population was 98,850.

The Authority’s current treatment process is activated sludge. The design average daily flow is 8 MGD, and the receiving waterbody is Arkansas River which is listed on the 303(d) list for enterococcus.

The Authority has a lift station that is not sufficient to convey current peak wet weather flows. Heavy rains result in wastewater inflow that overwhelms the current lift station causing a discharge of untreated sewage to the adjacent Adams creek. High wet weather flows and stormwater flows have also caused flooding of the lift station pump room and damage to the pumps, motors and equipment resulting in failures of the lift station. The Authority is currently under consent order for excessive inflow resulting in the discharge of untreated sewage to Adams creek. In an effort to address the issue, the Authority will utilize the funds to rehabilitate the existing lift station.

The Authority will also be making improvements to their existing sanitary sewer system. They will utilize the funds to install 2,100 linear feet of 8-inch sewer line and demolish the South Park South Lift Station.

Finally, the Authority has begun transitioning to drive-by AMRs for the system to replace old, inaccurate meters and help account for water loss. The system has the Neptune R900 Mobile AMR system which allows for expansion at the discretion of the Authority. In this phase the Authority will utilize the funds to install approximately 10,000 AMR meters.

These projects will help to meet Oklahoma's Water for 2060 goals by focusing on water conservation and efficiency, while reducing unintended flows to the wastewater treatment plants.
