• enable sewer line inspection and rehabilitation activities
• diagnostic tool for wastewater and storm water collection systems.
• support the acceptance of new sewer lines
• internal evaluation and trenchless rehabilitation of existing lines.

Cleaning sewer lines

• dislodges and removes accumulated debris
• restores optimal system hydraulic conditions
• minimizes line blockages, including grease and roots
• assists in odor control
• extends the life and function of a collection system

Inspection Procedure

• measure component parts
• examine line for roots, structural defects, and debris
• identify infiltration and inflow

Inspection Procedure

System rehabilitation can be a daunting task for utility agencies. Even after the completion of SSES activities, rehabilitation contracts and specifications must be prepared, bid, awarded, completed, and work accepted.

This process often involves multiple contractors utilizing numerous available technologies. Such contracts demand active oversight to ensure service reliability.

The result is quality, cost-effective rehabilitation to the ultimate benefit of the receiving agency and its customers.

MPEG-1 and MPEG-2

• ability to link to inventory records
• individual video frames can be catalogued, saved, located, and printed by observation
• used with non-linear storage to break away from the advancing and rewinding associated with VHS

What this means for you

• Combined GIS and inspection data
• Work order tracking
• Maintenance management
• Rehabilitation tracking
• Flexibility in the retrieval, sorting, querying, and reporting of stored records.

    Contract maintenance services for collection systems promote a partnership with agencies to maximize limited resources to effectively augment available resources in a synergistic relationship. Services are effective for small and large collection systems, where a multi-functional crew can service numerous communities on a revolving basis. Skilled personnel is used to perform routine preventive maintenance tasks. The result is a more efficient collection system optimizing the use of existing personnel and budget.

    DEFLECTION TESTING is conducted for the acceptance of new sewer lines. Pulling the mandrel, equal to 95 or 97 percent of the average diameter of the line, from manhole to manhole can determine whether excessive deflection, offset joints, protruding service connections, or other obstructions occur. Our innovative approach uses a CCTV camera behind the mandrel to determine location and type of defect encountered. This provides efficient and cost-effective correction of identified defects and video documentation of each line tested.
