Improving Baton Rouge’s Sewer System with New Wastewater Pump Stations

Stanley Consultants designed 16 new replacement pump stations for the City of Baton Rouge to resolve city-wide sewer problems and position the City to realize millions of dollars in fiscal savings through a 25-year planning period

For many years the City of Baton Rouge and East Baton Rouge Parish (C-P) have worked to resolve city-wide sewer problems.  Of primary concern is sanitary sewer overflow.  Excessive rain, groundwater in the collection lines, leaky manholes and undersized sewage pump stations have all led to the discharge of untreated sewage into the environment.  This discharge has compounded the major urban pollution problems that C-P is experiencing from non-point sources of runoff entering lakes, bayous, creeks and rivers.

To improve the quality of life for residents, as well as comply with federal mandates, the C-P has embarked on a parish-wide program which includes comprehensive rehabilitation projects, capacity improvement projects, and wastewater treatment and storage improvement projects. 

The C-P retained Stanley Consultants to design 16 new pump stations using submersible pumps to replace existing pumps stations that vary in size from 100 gpm to 20,000 gpm.  The three existing inline booster pump stations and 13 small duplex pump stations are being replaced with submersible pump stations that will have between 4 to 6 pumps.  The three larger stations will be modeled using computational fluid dynamics to ensure that the flow from the station meets the system demand.  Careful consideration is being given to how to switch the flow once the new stations are completed as all existing pump stations must remain in service during construction. 

These projects are expected to improve efficiencies, and position the C-P for millions of dollars in fiscal savings through a 25-year planning period.
