Project Overview

Updated March 12, 2018

Environmental Services—your sewer and stormwater services provider—is designing a project to repair or replace up to 7,000 feet of public sewers and build up to 39 green street planters to remove 2.6 million gallons of stormwater a year from the sewer system in the northwest portion of the Sunnyside neighborhood and a portion of the Buckman community. Many of the existing combined sewer pipes are at least 100 to 120 years old and deteriorating or undersized for the sewer and stormwater flows in this area. These improvements will protect public health, property and our environment and reduce the possibility of sewage releases into streets, homes and businesses.

Your neighborhood has a combined sewer system, which mixes sewage from homes and businesses with stormwater runoff from streets in the same pipes. When it rains, sewers can fill to capacity and back up into basements and streets. Combined sewage is contaminated with bacteria and pollutants washed off streets. Green streets help keep the combined sewer system running efficiently by keeping the stormwater out of the system. Many of the sewer pipes in the area need replacement because they are too small to carry the amount of stormwater in the area and they are deteriorating due to age.
