Two Early Christmas Breaks, but a Happy New Year Emergency Pipeline Project
In December 2011, a large utility owner in Texas experienced two major sanitary sewer pipeline failures on a 48-in. sanitary sewer main. Emergency design was completed within three weeks, and construction was completed within 90 days with the replaced 48-in. sewer main back in service in April 2012. This municipality serves nearly 1.3 million people and more than 400,000 wastewater customers in Texas. Like many large urban wastewater providers across the nation, the municipality is responsible for the maintenance and rehabilitation of aging infrastructure. This entity maintains and operates more than 5,200 mi of 12-in. and larger diameter pipe in the collection system and three wastewater treatment plants. This paper will focus on the fast-track emergency design and construction of more than 4,800 linear ft of 48-in. sewer pipeline replacement within a heavily traveled roadway. Unique project design issues included double-barrel siphon and air jumper design, temporary siphon structure and operational sequencing, hydraulic analysis and modeling, pipeline trench design, and a condensed design timeline. Challenging construction issues included two separate roadway contracts for construction sequencing; expedited submittal reviews; limited working area; traffic control; accelerated materials delivery; flowable fill requirements; and coordination with city, county, and state agencies.
