SECTION 3. SOUTH BASIN PROJECTS
3.4.6 SFL-C-0006 (Nicholson Drive – Highland Road – Perkins Road Capacity
Improvements)
Project Description
Purpose of the Project / Project Background
The SFL-C-0006 (Nicholson Drive – Highland Road –Perkins Road Capacity Improvements)
project consists of forcemain and gravity upgrades in the South Forced Lower Basin. The
project has been divided into two phases during construction for ease of execution: Phase A
- Willow Grove Capacity Improvements and Phase B – Nicholson Drive – Highland Road –
Perkins Road Capacity Improvements.
The Phase A (Willow Grove Capacity Improvements) project consists of forcemain and
gravity upgrades in the South Forced Lower Basin. This project includes the upsizing of
forcemain and gravity mains in an area that extends east to the intersection of Siegen Lane
and South Mall Drive and also to south to Perkins Road. The upgrades are designed to
alleviate chronic SSOs at the pump stations and increase the gravity main capacity. The
upgrades range in size from 8 inches to 18 inches in diameter.
The Phase B (Nicholson Drive – Highland Road – Perkins Road Capacity Improvements)
project consists of forcemain and gravity upgrades in the South Forced Lower Basin. This
project includes the upsizing of forcemain and gravity mains in an area that extends north
to the intersection of Jefferson Highway and Tiger Bend Road and continues south to the
South WWTP on Gardere Lane. The upgrades are designed to alleviate chronic SSOs at the
pump stations and increase the gravity main capacity. The upgrades range in size from 6
inches to 24 inches in diameter.
Location – Phase A
The Phase A (Willow Grove Capacity Improvements) project involves the replacement of
portions of the South Forced Lower forcemain and gravity systems as shown in Figures 3-
34A. The majority of the contributing flows are from residential areas. The upgrades can be
broken into the following segments.
Forcemain segment PS 223 to SS312 starts at PS 223, which is at the intersection of Roy
Emerson Drive and Don Budge Avenue, and travels overland to node SS312, which is on the
corner of Lew Hoad Avenue.
Forcemain segment Willow Grove added to the PDP at the request of the DPW. Forcemain
starts from Willow Grove forcemain connection to existing 10-inch forcemain at the north
side of KCS railroad. New 12-inch forcemain follows KCS railroad easterly direction
approximately 1,600 LF and then crosses to the north side of Ward Creek. Approximately
600 LF runs parallels to Ward Creek and extends all the way to PS944. Crosses at south side
of the Ward Creek near Siegen Lane overpass and connects to existing 18-inch forcemain.
The existing 14-inch crossing will be abandoned.
Gravity segment 944-01006 to PS 944 begins near the intersection of Mint Drive and
Buttercup Drive and runs east along a drainage path to PS 944, located near the intersection
of Andrea Drive and South Mall Drive.
