BACKGROUND The 4-inch steel water main along the alley south of La Porte Street between First Avenue and Saint Joseph Street was installed in 1916. In recent years, Public Works Services Department maintenance crews have made several emergency repairs to this water main, primarily due to its age. The project replaced the existing 4-inch steel water main with an 8-inch ductile iron water main. Ductile iron is the industry standard for water pipes and has corrosion resistance and strength. Ductile iron can also tolerate movement or deflection without breaking. This results in improving the overall reliability of the City’s water distribution system.
