The Sewer System Improvement Program (SSIP) is
charged with implementing efficient, high quality, and
reliable wastewater projects that directly impact our
quality of life.
We operate our wastewater system 24 hours a day, 7 days a week,
365 days a year, in a manner that is inclusive of environmental and
community interests, and that sustains the resources entrusted to
our care. The Wastewater Enterprise operates and maintains more
than 1,000 miles of sewers, 25,000 storm drains, and three treatment
facilities, the oldest and largest all-weather facility of which was built in
1952—the Southeast Treatment Plant.
The SSIP supplements our Renewal and Replacement Program by making
significant capital investments to upgrade our aging systems, using
modern equipment and processes. These projects bring improvements
to our most critical infrastructure, so we can ensure a resilient, reliable,
and sustainable system now and for generations to come.
The SSIP uses specific, measurable factors, known as Levels of Service
(LOS), to prioritize projects and evaluate Program success. The LOS
goals ensure that the projects not only meet our technical needs but
work to balance social, environmental, and financial factors, while
managing program and project-level risk.
