PREVENTIVE MAINTENANCE / CLEANING CREWS:
The Rothesay Municipal Operations Departments has an aggressive preventive maintenance program that ensures the sewer mains remain in proper working order and prevents many problems before they occur. Hydraulic sewer jet cleaners are used to clean sewer lines with high pressure water hoses; removing grease, grit and other debris from the lines. The sewer jet cleaners are also equipped with hydraulic root saws that are used to cut tree roots from main lines where roots are a problem. In addition to cleaning sewers, system operators also respond to blockage stoppage complaints. The program`s goal consists of routine cleaning of every public sewer main in which an obstruction may result in a backup into a residence or business. The routine cleaning frequency for these lines is intended to be at least a minimum of once every five years.

MUNICIPAL WATER and WASTEWATER CREWS:
The Sanitary Sewer Maintenance Section provides 24/7 service in response to reports of sanitary sewer backups and overflows. Upon being notified of a problem, a system operator will review the service request and may call for a hydraulic sewer jet cleaner to be dispatched to the location to aid in service restoration. Generally, the crew will contact the complainant to determine the nature and extent of the problem. The operator then inspects and cleans any sewer 100 mm in diameter or larger which could remedy the problem. Any obstruction determined to be in a public sewer is followed up with an internal TV inspection of the sewer line. In most cases, after a complete review of the incident, the location and the cause of the obstruction or blockage can be determined. If the problem is in the customer`s line, they will be advised to contact a plumber or sewer service company.

CLOSED CIRCUIT TELEVISION INSPECTION:
The Water and Wastewater Maintenance Section uses a state of the art closed circuit television system to internally inspect sewer mains and service line connections. This system consists of a color camera pushed through sewer lines which transmits a picture to a monitor and video recorder located inside a Rothesay service vehicle. Using this system, problems can be located and identified quickly and without excavation so that proper corrective actions can be taken.

REPAIR CREWS:
The Rothesay Municipal Operations Section operates two repair crews. The crews are responsible for repairs to manholes and shallow sewer mains less than 3 meters deep. Outside contracted help is generally required for repair on deeper sewer mains. Excavations have been up to 22 feet deep. These crews repair sewer mains that have been determined to be in poor condition by TV inspection that was done following a stoppage or as a result of a problem suspected during routine cleaning.

STATE-OF-THE-ART-METHODS:
The Rothesay Municipal Operations Department is constantly seeking methods to do jobs that are safer, more cost effective, and at a minimum inconvenience to our customers.
When conditions warrant, sewer lines can be rehabilitated or installed by several different methods of internal trenchless rehabilitation, eliminating the need for open excavation. This system takes only hours as opposed to days for conventional methods. Rothesay has completed installations using directional drilling to purposely avoid open excavations and unnecessary road closures when conditions are favourable to this type of install.

ACCOUNTABILITY:
The Rothesay Municipal Operations Department places much emphasis on accountability of its activities and functions throughout the year. To provide this service, inspection/service reports are compiled to maintain a record of all work undertaken from a customer service request. From this data, monthly reports are produced to provide an accounting for various activities.
Producing and storing these kind of reports enables the Water and Wastewater Operators to monitor its work activities, its production, and our systems performance, thereby making it possible to better serve you and the community. |
