Located roughly 60 miles away from the Rio Grande River-U.S.
Mexican border in Edcouch, Texas, the Delta Lake Irrigation District (the
District) is solely responsible to divert water to the surrounding community for
irrigation, municipal and domestic use throughout the district. A major part of
these efforts involved the construction of the Delta Lake Reservoir in 1938 in order
to provide a more reliable availability of water to meet the District’s needs,
including several irrigation canals along the reservoir.
An existing concrete culvert bridge had to deteriorated to
the point that a replacement was needed over one of the many Delta Lake
irrigation canals. The District first considered replacing the existing beam
bridge with reinforced concrete pipe (RCP). However, Troy Allen, the District General Manager, reached out to Contech Engineered Solutions in an attempt to find an
alternative, cost-efficient and durable irrigation solution for the site.
Ultimately, the District decided to use
DuroMaxx® steel reinforced
polyethylene (SRPE)
to cross the canal.
DuroMaxx SRPE can be manufactured in custom lengths, including
the desired 40’ length of pipe. This provided the structural solution needed as well as substantial savings on installed cost as no joints would be required. The
longer lay length provided a great alternative which allowed the District to
install a single section of 84-inch diameter DuroMaxx for a quick and relatively
simple installation process.
Given the tight time constraint considering the rapid deterioration
of the existing bridge, the District’s own crew installed in December of 2018. The
installation took place over a three-day period. Open and cut in place took
place on the first day at the site. The installation of the DuroMaxx SRPE pipe
culvert was performed on the second day, and the initial and final backfill was
completed on the third day.
Due to the longer lay length, familiarity with the product,
ease of handling and dependable durability in a larger diameter, the Delta Lake
Irrigation District was extremely satisfied with DuroMaxx SRPE as the optimal
solution to replace the existing beam bridge.
