HOW OLD PIPE IS RELINED Click photos to enlarge

MWRA's water system is made up of over 300 miles of pipeline. The structural integrity of our water pipes and aqueducts is critical. Well-maintained pipes give MWRA customers the full benefits of our high-quality water and reliable service.

REHABILITATION AND REPLACEMENT

Certain older water pipes, especially those made of unlined cast-iron or concrete, need to be replaced or cleaned and lined to prevent bacteria growth and rust build-up.

Our Distribution Pipeline Improvement program is structured to replace on average between six and seven miles of pipe per year.

These projects are closely coordinated with local town officials and road improvement projects.

LOCAL PIPELINE AND WATER SYSTEM ASSISTANCE PROGRAMS

The MWRA also provides assistance to cities and towns within the water service area for rehabilitation of their locally-owned water distribution systems. About 33% of the 6,400 mile network of community pipes are older unlined pipes.

The goal of the program is to maintain water quality by aiding communities in the improvement of the local pipes that water must pass through to reach consumers.

Interest-free loan funds are distributed quarterly and communities are required to repay the principal amount of each year's loan over a ten-year period beginning one year after project funding.
