Maintaining a collection system begins with cleaning. Settlement, debris, and deleterious materials clog sanitary and storm pipes creating blockages and flow stoppages that ultimately result in sewer overflows (SSOs). A progressive Operations and Maintenance (O&M) program should include annual sewer cleaning to assure that the systems hydraulic capacity is regulated at its full design. 

Fitted with a high-capacity vacuum and large debris tank, sewer combinations truck can clean pipes and remove materials that can block a sewer line. These multi-purpose vehicles allow for many situations where debris can accumulate including Catch Basins, Manholes, Wet Wells, and Lift Stations. By adding an extension hose,reaches up to 100 feet from the vehicle can be achieved.

Root intrusion in sewer lines occur when trees seek the natural nutrients in a pipeline. Entering through open joints and holes in pipes, they continue to grow creating blockages and slowing down the natural flows. Mineral deposits on the interior of sewer lines are created by groundwater entering joints and holes and leaving behind the calcium and magnesium contained in these hard waters. Over time the hard deposits build up lowering sewer capacities. By using specialized nozzles in combination with sewer jetting equipment, these naturally occurring problems can be removed.

Steam Cured CIPP offers a proven trenchless repair of aging laterals with a minimum 50-year lifespan at a fraction of the cost of dig and replace. A resin impregnated, “T” shaped flexible tube is inverted, inflated, and then cured in place using heat. The CIPP liner conforms to the walls of the host pipe resulting in a smooth, seamless new pipe for lengths up to 120’ from the mainline and 360-degrees of the mainline.

Manholes, Catch Basins, and Inlets are exposed to overhead traffic, freeze/frost cycles, road salts and Hydrogen Sulfide (H2S) attack. Replacement is expensive, disruptive, and time consuming. These weakened structures can be trenchlessly renewed by employing various methods to apply various products to the surface, stopping infiltration, and increasing the life cycle of a collection system. We use Micro-Silicate Mortars (MSM) that are Portland-based concretes embedded with micro-fiberglass rods that combine to provide high compression strengths and Calcium Aluminate Mortars (CAM) are infused with aluminum particles to provide additional protection against H2S in Structures.  For extra protection, Epoxies are specially designed and proven to provide chemical resistance to a variety of chemicals while bonding with excellent adhesion to concretes, metals, and fiberglass materials.

The Sectional or point repair is a cured-in-place Short Liner repair for wastewater and storm sewer pipes. Its simplistic installation allows for a quick repair in mainlines from 6” to 24” in diameter with a short curing time. The Short Liner is perfect for segments that are overall in good shape and need just a single or multiple repairs but not a full manhole to manhole liner. A fiberglass-reinforced mat is impregnated with a resin, wrapped around an inflatable bladder, and then pulled into place. After centering the unit over the damaged section, the bladder is inflated. Once cured, the result is a trenchless repair solution that is mechanically locked in place.
