Smoke and Dye Testing Services

Smoke and dye testing are two cost-effective methods of identifying which taps and lateral lines connect from a residence, business or other structure into the main sewer line.† By flushing a colored dye tablet down a pipe toilet, we can accurately identify which sewer segment it drains into.† Smoke testing is generally used to identify the source of inflow, infiltration and ex-filtration problems. Both the smoke and dyes used for these tests are non-toxic and environmentally safe.

Locating Services

Identifying the location of buried pipes can be time consuming and costly, especially if digging is required.† It is our goal to provide cost-effective, precise and timely pipe location information as part of our commitment to our customers.† SWS uses state-of-the-art equipment and trained personnel to accurately pinpoint the location and depth of underground pipes.† Utilizing Radiodetectionís RD8000 locator, we can accurately locate pipes as deep as 25 feet underground.†

In conjunction with this device, high-powered sonde transmitters bounce radio frequencies back to the locator enabling us to trace non-metallic sewers, drains, ducts and pipes and to find blockages or collapses in the structure.

This information is useful when updating GIS data for mapping systems that may be inaccurate and for utility companies who need to dig around buried conduits.

Underground pipe locating


SWS strives to maintain high safety standards and environmentally-friendly practices in all we do.† Thatís why we promote the use of hydro-excavation. With the ever increasing congestion of underground utilities such as gas, electric, fiber optic and telecommunication lines around buried pipelines, it is more important than ever to find a safe and efficient solution to removing the surrounding ground.† Using pressurized water and a vacuum truck to safely dig and expose these utilities, we remove soil and water slurry without damaging the underlying infrastructure.

Using water as a lubricant, we break up the soil in a non-destructive manner and vacuum the debris into a self-contained holding tank.† This minimizes any potential runoff into municipal sewer systems or watershed areas.† In addition, water is chemical-free and controls static electricity, thereby reducing the threat of injury to the workers, residents and the environment.

Low Pressure Air Testing Services

Air testing is a useful tool in identifying infiltration and ex-filtration within a pipe segment or at the joints.† It is important to verify that a pipe is water tight.† Extensive infiltration of groundwater can overload the treatment plant or adjacent sewer lines.† Excessive ex-filtration would allow sewage, chemicals and other contaminants into our drinking water and waterways.

Air testing can be used for construction acceptance and for preventative maintenance measures.† When pipe defects are identified early, repair decisions can be made more effectively.
