Sanitary Sewer Operations and Maintenance

The Sanitary Sewer Operations and Maintenance program is lead by two Operations Superintendents and split into two distinct sections; the Collector/ Analysis, Inspection, Maintenance, Support (A.I.M.S) section and the Pump Station section.

The Sanitary Sewer Operations and Maintenance program is lead by two Operations Superintendents and split into two distinct sections; the Collector/ Analysis, Inspection, Maintenance, Support (A.I.M.S) section and the Pump Station section. The Collector/A.I.M.S section has an Operations Supervisor that oversees the daily operations and reports to the Operations Superintendent.
Operations Superintendent
Two Operations Superintendents are directly responsible for all day-to-day operations of the two sanitary sewer sections. One Operations Superintendent oversees the Collector/A.I.M.S section, with the help of the Operations Supervisor. The areas of concentration include construction installation and repair projects, A.I.M.S –CCTV inspection of Mainlines and Mainlines cleaning. One Operations Superintendent oversees the Pump Station section. The areas of concentration include Maintenance Specialists (responsible for the mechanical support of the station), Instrument Control Specialists (responsible for all electrical components of the station), and Generator Specialists (responsible for maintaining all generators for the stations).

Sewer Stoppages
Crews are engaged in clearing residential and industrial sewer stoppages from the city's right-of-way line to the sanitary sewer mainline. Crews are available for this work on a sixteen hour a day basis. After hours requests for service are received by the Police Department. They are routed to an on-call Wastewater Division Operations Superintendent who determines the appropriate response.
Collector/AIMS Section
Collector/AIMS Operations Supervisor
The Collector/AIMS Operations Supervisor is responsible for supervising and coordinating all work assigned to the AIMS and Collector sections as well as how they mutually support each other in assigned operations. This position will assist the Operations Superintendent in the day to day operations, maintenance and repair/replacement of the sanitary sewer system throughout the City of Newport News.
Collector Operations: sewer construction/installation/repair
This section is responsible for the repair or replacement of broken sanitary sewer mainlines, laterals, and manholes. This section also handles all new residence tie-ins, contractor coordination for new residential sewer connection issues and support in helping septic tank users transition to City of Newport News sewer service.
Analysis, Inspection, Maintenance and Support (AIMS)
The primary mission of the AIMS group is the analysis and inspection of the City of Newport News sanitary sewer mainlines, laterals and manholes. This cyclic program utilizes state-of-the-art equipment including laptop computers, CCTV, robotics, and GIS (Geographic Information Systems) systems to analyze the entire City of Newport News sewer system by pump station service area utilizing all of these tools and more. These analysis/inspection programs results in identifying all problem areas of the service areas sewer system, repairing the problems or replacing all damaged or aged sections through the division's Capital Improvement Program (CIP), and to map the entire service area components with GPS (Global Positioning Satellite)/GIS instrumentation.
Additional units in the AIMS group are assigned to inspect sewer lines prior to street reconstruction. This concept permits a comprehensive inventory of the city's sewer lines in advance of major street work. Crews are also assigned to clean sanitary sewer mainlines throughout the city. Preventive maintenance of these lines help to mitigate sewerage overflows.
One of the components of our sewer inspection program is smoke testing of the sewer mainline. Smoke testing is designed to find leaks in the sewer system. If we are planning to conduct this type of inspection in a residential area, a letter is supplied to the citizens.  The letter describes the types of work that we are conducting as well as detailed information about the product we are using.
Here are links to the Notice to Residents Letter and some basic Questions and Answers related to smoke testing.
It is important to note that if smoke is observed inside a residence, there is usually one of the following problems:
1. A dry trap from a basement or shower.
2. A leaking toilet wax seal.
3. A stopped up roof vent.
In the cases listed above, there is a potential for sewer gas to enter the residence. Immediate action should be taken on the part of the homeowner to repair the problem.
Here is an example of some problems that can cause infiltration and inflow into the sewer system.
Here is a sample of how your sewer lateral ties into the sewer system.

Pump Station Operations
Pump Station Operations Superintendent
The Pump Station Operations Superintendent is responsible for the day-to-day operation and maintenance activities related to over 180 sewerage and stormwater Pumping Stations along with 104 Pump Station Emergency Power Generation Systems.
Pump Station Operation and Maintenance
There are currently over 180 pumping stations located throughout the city. Maintenance & Instrumentation Control Specialist Teams under the direction of the Pump Station Operations Supervisor perform preventive and corrective maintenance on all mechanical and electrical equipment associated with the stations. Additionally, three Generator Specialists perform preventive and corrective maintenance on emergency generators for public buildings and pumping stations.
Modern technology plays an important role in the activities of this group. The latest upgrade in the City’s Supervisory Control and Data Acquisition technology (SCADA) system is in the final stage of analysis and review prior to finalization. This new SCADA system will integrate existing and new systems to continuously monitor all sewer flows, wet well levels, system pressures, and overall condition of the pumping stations from our operations center in the Public Works Complex. It will also allow a significant improvement in system integration between our software and hardware systems as never before. In addition this will also allow our pumping stations to be remotely controlled by specialized computer technology as needed during severe storm events.
An apprenticeship program for Pumping Station Mechanical and Electrical personnel has been established which will help to assure that our staff is trained in the latest technology and personnel development training.
