Explores the preventable structural failure of a manhole, causing injury after deteriorated concrete separated from the wall. BMC’s technical review identified critical shortcomings in inspection practices, rehabilitation methods, and worker safety procedures.
A 54-inch reinforced concrete pipe was found to be structurally sound overall, but the evaluation revealed manufacturing quality control issues and reinforced the need for thorough inspection before and after installation.
This case study examines how significant structural deterioration and infiltration in a brick manhole led to soil migration and recurring sinkholes. Although early signs of washouts and infiltration were present, delayed action allowed the damage to worsen over several years.
This case study examines how an incompatible installation and missed inspection oversight created a serious safety risk. A technical review by Back Municipal Consulting identified critical deficiencies that contributed to the failure.
Manholes may not be the most glamorous part of our infrastructure, but they play a crucial role in managing wastewater and stormwater systems. To ensure the efficient and safe operation of these systems, monitoring various parameters is essential. One often overlooked but vital parameter to measure in manholes is pH.
Rehabilitating sewer systems is essential for a number of reasons, including public health, environmental protection, and economic benefits.
