More than a few folks are asking — just what is going on along Louise Avenue between Main Street and Union Road where a temporary pipe has been placed along the gutter on the north side of the street?It is part of the city’s $2.8 million sewer line rehab effort to avoid a repeat of the sewer lines failure in February 2017 on Union Road near Alameda Street where part of the street started to cave in.Public Works Director Mark Houghton noted the pipe above ground is temporarily moving wastewater while contractors install a liner in the 30-inch main pipe.The sewer line has sustained significant corrosion and loss of concrete material due to exposure of hydrogen sulfide within the 30-inch reinforced concrete pipe.Altogether 1.6 miles pf existing sewer pipe will be lined from a lift station between the golf course and the Morezone Baseball Field that then goes to Union Road in alignment with Eucalyptus Street, then heads north along Union to Louise Avenue, and then heads east along Louise Avenue to Crestwood Avenue. Traditional pipe replacement using deep excavation was not recommended due to the considerable traffic flow on Union Road and Louise Avenue. Traffic disruption would be limited and immediate reopening of the sewer main can take place once the liner is cured.
