Location: Alley between 38th & 39th Avenue East, and Itasca & St. Croix Street:
Sanitary sewer segment MH070117-MH070118 is a 10-inch Vitrified Clay Pipe (VCP) installed in 1914. During a routine inspection by ESD environmental engineering staff in 2018, sanitary segment MH070117-MH070118 was discovered to have multiple defects throughout. Such defects include broken/cracked pipe, large offset joints, and reverse slope. Additionally, a sinkhole has formed over a section of broken pipe within the alley. This pipe segment is at risk of collapse due to the inflow of stormwater during intense rain events, which increases the likelihood of a sewer backup or sanitary sewer overflow.
The project shall consist of removing 458 lineal feet of 10-inch Vitrified Clay Pipe (VCP) sanitary sewer, removal of two (2) brick sanitary structures, installing two (2) concrete sanitary structures, installing 458 lineal feet of 10-inch Polyvinyl Chloride Pipe (PVC), connecting existing sewer services, and re-establishment of gravel alley. Sewer Service will not be interrupted during construction, however, it is STRONGLY encouraged that water usage is limited during construction for residences connected to the sewer main. The contractor will be in communication with the homeowners in advance to when their service lateral will be disconnected and reconnected to the new sewer main.
