Buried Infrastructure Services
Beneath our towns and cities lay billions of dollars’ worth of underground infrastructure. Much of this infrastructure was built many decades ago, and is reaching a point of dangerous deterioration. Hazen and Sawyer has an established track record of assessing and rehabilitating or replacing aging buried infrastructure, and in designing repairs and improvements.

Studies have shown that it costs 3 to 4 times more to repair critical pipes after they fail than to rehabilitate them at the first signs of deterioration. Pipes in poor condition are very vulnerable to increased infiltration and inflow, resulting in possible sewer system overflows (SSOs) and further acceleration of pipe failure. These conditions threaten public health and the environment, along with the economic stability of the service provider.
