In 2010, Miami-Dade Water and Sewer Authority (MDWSA) instituted a continuous inspection and repair program for their 48 in. to 96 in. dia. prestressed concrete cylinder pipes (PCCP). With brief periods to perform repairs and field conditions (e.g., high groundwater levels) making pipe replacement difficult, MDWSA preferred to implement internal repairs on selected distressed pipe pieces. Over the years, SGH has analyzed failure risk, designed repairs for more than 100 MDWSA pipes, and provided field engineering services during repairs.
