1. BACKGROUND:
A. Need. This legislation authorizes the Director of Public Utilities to enter into a professional design services agreement with RW Armstrong for the CSO Regulator Sluice Gate Modifications project for the Division of Sewerage and Drainage. The Division has determined that these design services cannot be performed by City personnel at this time, and has planned for the procurement of these services on a routine basis.
With increased treatment capacity at the Jackson Pike and Southerly Wastewater treatment plants in 2010, the OSIS will be able to convey additional wet weather flow reducing the frequency and volume of combined sewer overflows at each regulator for a typical year rainfall. Hydraulic modeling of the collection system performed for the WWMP/LTCP determined that sluice gate settings within CSO regulators can be adjusted to capture more wet weather flow into the OSIS.
The following CSO regulators are included in this project: Hudson Street, Doe Alley, Frambes Avenue, Indianola Avenue, First Avenue, King Avenue, Henry Street, Chestnut Street, Spring Street, Long Street, Broad Street, Town Street, Peters Run, Whittier Street, Moler Street and Markison Avenue.
