Niagara Falls Water Board Sanitary Sewer System Management Plan - Year 12 Update

JM Davidson Engineering, D.P.C. (JMD), as a subconsultant to Arcadis, assisted with the development of the Year 12  Update to the Sanitary Sewer System Management Plan (SSSMP) for the LaSalle Area of the City of Niagara Falls, NY. 

The LaSalle Area refers to the separate sanitary sewer area located on the east side of the City.  This area has historically experienced wet weather-related sanitary sewer overflows (SSOs).  As part of the Order on Consent R9-20080525—32, an 18-year Detailed Work Plan was developed to address the SSOs.  The work under this contract was for the re-evaluation of the SSSMP at Year 12.  This evaluation included installation of 15 flow meters throughout the LaSalle area sewer system and flow monitoring from March 2019 through June 2019; examining the specific work performed in Years 6 through Year 11; examining planned activities in Years 13 through Year 18 considering recent flow monitoring results; and reprioritizing the work moving forward, as necessary, to favor the most effective approach for implementation of corrective measures.

JMD’s specific tasks related to this project include:

• Developing the draft report, including review of prior SSSMP evaluations and work completed in the collection system, and assistance with flow monitoring analysis and re-prioritization of rehabilitation measures
• Preparation of final report
• Participation in workshop meetings with NFWB and NYSDEC
