SECTION 3. SOUTH BASIN PROJECTS
3.4.8 SFU-C-0002a (O’Neal Lane Pump Stations Group A)
Project Description
Purpose of the Project / Project Background
The SFU-C-0002a (O’Neal Lane Pump Station Group A project includes segments
previously included in SFU-C-0002 (Multiple Pump Stations - Jones Creek Road - Tiger
Bend Road), SFU-C-0003 (Multiple Pump Stations - O’Neal Lane) project, and SFU-C-0004
(Multiple Pump Stations - O’Neal - S. Harrell’s Ferry) project. The combined project has
then been split into two projects, Group A and Group B, since the November 2009 PDP.
The project involves the upgrade of PS 112, PS 148, PS 157, PS 170, PS 172, PS 211, PS 232, PS
247, PS 253, PS 274, PS 296, PS 316, PS 391, PS 428 and BPS 777. The upgrades will work in
conjunction with forcemain upgrades in the SFU-C-0005 (O’Neal Lane Pipeline
Improvements) project to alleviate chronic SSOs at and near these pump stations. The
upgrades will also allow the pump stations to handle future peak wet weather flows that
modeling predicts will exceed the existing maximum capacities.
Location
The locations of the pump stations included in this project are given in Table 3-23A and
shown in Figure 3-36A.
Scope
Table 3-23A shows the detailed scope of this project, which includes replacing 15 pump
stations; including converting BPS 777 from an in-line booster station to a wet well pump station.

Note: The existing maximum capacities for the PSs were obtained from the DPW Field Pump Station Maintenance
reference guide. The future peak wet weather flow was obtained from the BTRSSO hydraulic model.
