I/I Reduction Cost Effectiveness: The Results of Milwaukee MSD's Demonstration Project
Abstract
Facing the eventuality of sanitary sewer overflow (SSO) regulation from federal and state governments, many communities recognize the need to reduce wet weather flows in their systems. Unfortunately these same communities struggle with choosing the right path toward infiltration and inflow (I/I) reduction. In many cases, this trepidation is the result of not having enough local cost-effectiveness data to support choosing a specific approach for I/I reduction. As a result, communities have either a) selected a direction based on best technical judgment, or b) done nothing at all. The project presented in this paper represents a third option taken by the Milwaukee Metropolitan Sewerage District (MMSD). Starting in 1999, MMSD initiated an I/I reduction demonstration project. The purpose of the project was to implement I/I reduction projects that would provide conclusive data on effective practices and provide local construction costs. Brown and Caldwell was hired at the outset to consult MMSD on establishing project standards, selecting project locations, and performing an effectiveness evaluation of each implemented project.MMSD's demonstration project involved reviewing past sewer system data for the service area to determine if there were any obvious locations for performing I/I reduction. This evaluation indicated that no such locations existed. As a result, MMSD published a Request for Proposals for its satellite municipalities to respond to. This RFP resulted in 14 proposed projects for I/I reduction, from which MMSD selected 8 for implementation. Following selection, MMSD entered into intergovernmental cooperation agreements (ICAs) with each of the municipalities so that the municipalities would implement the projects with MMSD grant funding. One of the more important considerations for MMSD in this regard was the extent to which the results would be useful to other municipalities in the MMSD service areaThe information presented in this paper will benefit other municipalities that desire to set up their own I/I reduction demonstration projects. The paper presents the criteria used to evaluate potential project areas, what MMSD did to ensure the effectiveness could be estimated, and how the projects were constructed.
