Rockville Sanitary Sewer Projects
Manhole 1Capital Improvement Projects

Capital investments normally involve major City projects that have long useful lives. The Wastewater CIP Program Area provides for the planning, study, design and construction of wastewater projects. Wastewater projects (also referred to as sewer projects) address adequate and safe conveyance of wastewater to the DC Water owned and operated Blue Plains Advanced Wastewater Treatment Plant (Blue Plains).


Preventative Maintenance Program

Rockville Sanitary Sewer Preventative Maintenance Program consists of comprehensive inspections of the sewer pipes and manholes within the City wastewater collection system. The multi-year initiative investigates the City sanitary sewer system in order to protect public health and the environment, ensure compliance with state and federal requirements and ultimately renew aging infrastructure.

The Department of Public Works utilizes a Sewer Line Rapid Assessment Tool (SL-RAT) that uses acoustical sounds to quickly identify problem segments within the sewer infrastructure. Results from the SL-RAT assessment determine the areas that the City will inspect using robotic technology with closed-circuit television (CCTV) trucks. The video is reviewed and the condition of the sewers are evaluated and scored. The pipes and manholes with significant defects are prioritized for rehabilitation.

Sewer Rehabilitation

If a section of sewer is recommended for rehabilitation, it will be lined with a cured-in-place liner or it will be excavated and replaced. The CCTV sanitary sewer inspections do not impact customers' water or sewer service. The Sewer Main Rehabilitation CIP project (220-850-9G34) funds the rehabilitation of all sanitary sewers identified through the Sanitary Sewer Preventative Maintenance program.

The Department of Public Work's operating budget funds the daily work to inspect and manage the sanitary sewer system across the City. It totals approximately $1.4 million annually and includes all equipment, material, and personnel costs. The Sanitary Sewer Preventative Maintenance Program is separate from the City's CIP Water Line Replacement Program which focuses strictly on the pipes that carry the City's drinking water to residents and businesses.
