Sewer Rehabilitation Services

Innovative and cost-effective sewer rehabilitation services for residential, municipalities, construction, and engineering companies. Each of the trucks in our fleet are fully equipped with the most current and state of the art sewer rehabilitation equipment.

All of our technicians are highly trained in the following areas:

Learn about Inspection

CCTV Inspection Services

Sewer Technologies Inc. offers various no-dig methods for analyzing the physical condition of sewer lines. Pipe defects can be identified in all sizes of storm and sanitary pipes from 50mm to 3000mm.

Our fleet of trucks are equipped with the industry’s most state of the art equipment.   Each of our inspection vehicles has digital data-capture systems using Win-Can®, which is the market’s most innovative data collection and data analytics software.

Our CCTV Inspection systems and operators are the most efficient in the industry today. All operators are certified in NASSCO’s Pipeline Assessment Certification Program (PACP). CCTV Inspections are completed in accordance to OPSS (Ontario Provincial Standard Specification) 409 Construction Specification for Closed-Circuit Television (CCTV) Inspection of Pipelines.

Learn about Cleaning and Flushing

Cleaning and Flushing

cleaning-and-flushing-trucksWith our advanced, state of the art Cleaning and Flushing trucks, Sewer Technologies is able to provide high pressure cleaning and vacuuming of wastewater collection systems, storm water drainage systems, lift stations, manholes, catch basins, etc. We are able to clean pipes ranging from 100mm to over 2400mm. Our specialized sewer cleaning machines are able to release water pressure of approximately 75 gallons per minute into the manhole. The water begins to flush out all the debris lodged in the pipe then the air vacuuming system will draw all of the dislodged debris into a large debris tank.

Productivity is increased with Sewer Technologies combination cleaning and flushing truck, as larger debris and water tanks mean less time filling and dumping and more time cleaning the sewers.

Our crews are equipped with all of the specific cleaning nozzles, hydraulic reamers and milling cutters required to remove any foreign object including debris, gravel, roots, calcite, concrete, solidified asphalt, and other objects.

Learn about Trenchless Repairs

Trenchless Repairs

sam-working Trenchless or No Dig repairs are a less costly and green alternative to traditional dig and replace methods of pipe repair. Without the need for excavation, significant time is saved on digging and restoring trenches since most repairs can be completed within the matter of hours.

These processes also save time and costs in in site restoration, disposal storage and the traffic control associated with dig and replace methods. This also means less disruptions to residents and clients. Those who are dependent on the pipes in the repair locations won’t have to relocate or haul water manually for extended periods of time.

Learn about Manhole Rehabilitation

Manhole Rehabilitation

Manholes and other underground structures commonly account for approximately 25-30% of infiltration and up to 70% of inflow in sanitary sewer collection systems. The deterioration of these manholes can cause sewer overflows and endanger the surface above and the nearby environment.

Manhole rehabilitation solutions can cut back on the costs associated with infiltration. These problems can be overcome by the use of carefully placed flexible chemical grout. Manhole sealing is very effective where pipelines and manholes exist in a high grounds water table conditions. High quantities of ground water infiltrate manholes and this can increase the hydraulic load on the pipeline and this in turn can lead to sewer overflows, overloading of pumping stations and sewage treatment works.

Our trained technicians will drill holes within the manhole and utilize a specialized pump to inject grout behind the structure. When the chemical grout comes into contact with the catalyst (water) the chemical grout gells creating a waterproof, flexible seal.

After the injection has taken place the chemical grout will foam, expand and fill the void forming a tight, impermeable elastomeric seal, stopping the water flow (infiltration). Because the grout is on the outside of the manhole it cannot be pushed back into the sewer system.
