Projects

The Meeker Public Works Authority (Authority) located in Lincoln County serves 362 sewer customers and 484 water customers. According to the 2010 U.S Census the population was 1,144. This project received loan forgiveness as Phase II of the planning and design loan forgiveness program.

The Authority’s current treatment process is extended aeration. The design average daily flow is 0.2 MGD, and the receiving waterbody is Quapaw Creek, South which is listed on the 303(d) list for macroinvertebrate bio, and fish bioassessments.

The Authority’s wastewater collection system is comprised of roughly 34,500 linear feet of gravity sewer, 101 manholes and a lift station. Inspection revealed that a large part of the existing collection lines consists of vitrified clay pipe, which is likely creating a medium for inflow and infiltration (I/I) into the system, have exceeded their life expectancy, and are in need of replacement. Of the 101 manholes, 35 were found to be constructed of brick while 20 were uninvestigated as they could not be located. The clay pipe, brick construction manholes, and broken cleanouts are all sources for I/I.

In order to address these issues, the Authority will utilize the funds to replace wastewater lines using pipe bursting, replacing manholes on the replaced line(s), and sealing manholes not on the replaced line(s) with cementitious liner.

These improvements will address inflow and infiltration into the sewer collection system thereby reducing unintended flows to the wastewater treatment facility and preventing unpermitted discharges from wet weather.
