Topeka, Kansas, has approximately 760 miles of sanitary sewers. Although the City is constantly taking proactive measures to maintain their infrastructure, the inevitable deterioration of manholes still plagues this capital city. Like other cities throughout the nation, it perennially faces the common problem of damage to its manholes caused by H2S corrosion. Today's market offers an unprecedented range of solutions for utility asset protection. For manhole rehabilitation in particular, solutions can range from quick fixes that are "hold me overs" during emergency situations, to a plethora of sound rehabilitation options that provide long-term solutions. When considering solutions, numerous factors come into play. A "quick fix" in the form of a cement repair can sometimes serve the purpose and be cost-effective, however depending on the severity of deterioration of the structure, that is not always optimal. Investing in a long-term solution, while sometimes more costly upfront, ends up saving cities in the long run due to its long-standing effectiveness. Long-term asset protection was the City of Topeka's goal, ultimately leading them to explore structural epoxy lining solutions for their manholes.
