SAN ANGELO – Utility contract crews are set to close the Johnson St. end of A&M Ave. Tuesday so the long awaited water main replacement project can commence.
According to information from the city of San Angelo, the South A&M-Johnson Street intersection, South A&M traffic traveling east will have reduced lane width; Southbound South Johnson traffic will be reduced to one lane Tuesday, Sept. 27 through Friday, Sept. 30.
According to COSA staff, the South A&M Avenue waterline from Avenue N to Johnson Street consists of existing 6-inch to 12-inch cast iron waterlines that have reached their life expectancy and have had continuous breaks and maintenance issues. This project proposes to replace the cast iron lines by means of pipe bursting with DR18 DIPS Fusible PVC pipe designed to be fully structural pipe meeting all external loading and internal pressure requirements.
Pipe bursting was considered as an alternative to traditional dig-lay-bury installation to reduce the project duration and impact on the citizens. In a price comparison to recently procured projects by the City, it has also been shown for pipe bursting installation to be more cost effective as compared to traditional installation methods.
Temporary services will be provided for each connection prior to flow isolation and will be maintained throughout the installation process until new connections can be completed.
In addition, ongoing utility replacement work continues on College Hills Blvd. from Vista Del Arroyo to Millbrook each day this week. That section of roadway will be closed as well.
