Storm Sewer Rehabilitation

Purpose:  This project funds the design and rehabilitation of corrugated metal pipe (CMP) storm drain systems installed in many locations, as well as studies to assess the condition of storm drain systems. The design and rehabilitation program will continue for all CMP systems in Rockville. CMP was used in the late 1960's as a means to install new drainage systems economically. Most of the systems have exceeded their design life and need repeated maintenance. CMP tends to rust through as a result of corrosion and erosion. Study recommendations may include repairs ranging from total pipe replacement (with concrete pipe) to spot improvements (with sections of metal plates) or relining the pipe, depending on pipe condition.

First Appeared in Rockville's Capital Improvement Program: Fiscal Year 1998.
