MWRA's I/I Local Financial Assistance Program provides $221 million in grants and interest-free loans to MWRA sewer communities to perform local infiltration and inflow "I/I" reduction and sewer rehabilitation. Funds are approved for distribution through Fiscal Year 2015.

Eligible projects include:

  • pipeline replacement
  • public and private inflow source removal
  • I/I reduction planning
  • sewer rehabilitation construction
  • engineering design
  • engineering services during construction

PROJECT BENEFITS

The program's goal is to assist MWRA communities in reducing I/I and repairing and/or replacing aging sewers.

This program is a critical component of MWRA’s Regional I/I Reduction Plan. Specifically, local sewer system rehabilitation projects are intended to at least offset ongoing collection system deterioration thus preventing a net increase in regional I/I. In the long-term, system rehabilitation should result in lower I/I, which will allow for future increases in sanitary flows (residential, commercial, industrial, and institutional) without a net increase in total wastewater flow. The program fosters efficient operation and maintenance of local sewer systems.


HOW FUNDS ARE ALLOCATED

I/I Local Financial Assistance Program funds are allocated to member sewer communities based on their percent share of MWRA’s wholesale sewer charge. Phase 1 and 2 funds (total of $64 million) were distributed for approved projects as 25% grants and 75% interest-free loans.

Member sewer communities receive 45% grants and 55% interest-free loans for local projects. Interest-free loans are repaid to MWRA over a five-year period beginning one year after distribution of the funds. Over the 16-year life of the program, more than $165 million has been distributed to fund 343 local I/I reduction and sewer system rehabilitation projects.

Distribution of the remaining funds has been approved through FY15.
