Public Notice  |  Project Plans

REQUESTER: Houston Public Works
LOCATION: Beneath Sims Bayou from Sunbeam Street to East Orem Drive along Martin Luther King Jr. Boulevard.
NON-FEDERAL SPONSOR: Harris County Flood Control District
REQUESTERS PROPOSED ALTERATION: The proposed project includes the installation of 24-inch waterline along Martin Luther King Blvd, will be comprised mostly of ductile iron pipe except for the section that goes beneath the Sims Bayou, which will be welded spiral wound steel pipe. The pipe will be installed beneath Sims Bayou utilizing two-pass micro tunneling. A 42-inch steel casing will be installed approximately 10-feet below the channel invert using a Micro tunnel Boring Machine. The steel water pipe will then be inserted into the casing with the annular space being fully grouted. A tunnel launching shaft is anticipated to be constructed on the north side of the Bayou while a retrieval shaft will be constructed on the south side of the Bayou with the tunnel. The exact size and shape of the shafts will be determined by the contractor performing the work.
Two access vaults will be constructed at either end of the tunnel that will allow access to the pipe for maintenance without having to excavate. A permanent and temporary construction easement from the Harris County Flood Control District (HCFCD) will be necessary to construct the retrieval shaft and access vault. Acquisition of the easements is currently in process and is expected to be complete in the Spring of 2024.
