Whether you're designing a municipal storm sewer, sanitary sewer, highway drainage system, culvert replacement, water management project, or underground storage system, Contech offers proven pipe solutions backed by decades of engineering expertise, nationwide manufacturing, and local technical support. Discover products that help improve performance, reduce installation costs, and deliver lasting value for transportation, commercial, residential, industrial, and water infrastructure applications.
Precast or cast-in-place manhole caps can be used to distribute live and dead loads from frames, grates, and traffic into the soil around the riser rather than directly into the pipe or access structure. This helps protect the pipe system while still allowing standard surface access.
Yes. Prefabricated wet wells can be manufactured with required connections, knockouts, and access features before arriving at the job site. The webinar showed large-diameter wet wells that could be dropped into place, reducing field construction work. Properly designed caps or load-distribution elements are used to transfer surface loads into surrounding soil rather than directly into the structure.
Ladders are not always required. Many municipalities and owners prefer to control access using their own ingress and egress procedures rather than permanently installed ladders. However, ladders can be provided when required. Depending on the application, they may be aluminum, steel, or fiberglass, and they are typically attached unless otherwise requested.
Aluminized Type 2 (ALT2) corrugated metal pipe can provide durability of over 75 years when used within appropriate pH and resistivity ranges. Proper material selection should always consider site soil and water chemistry.
The connection method depends on the pipe material. For steel reinforced polyethylene systems, riser extensions may be connected using seal-tight couplers designed to control groundwater infiltration when properly installed. For corrugated metal systems, extensions may be connected with a band and gasket, similar to a lateral connection.
Early coordination allows designers to evaluate alternative materials, prefabricated structures, hydraulic options, and installation methods before plans and specifications are finalized. This can reduce material cost, shorten lead times, simplify construction, and avoid oversized structures or unnecessary pipe upsizing.
Designers should identify large-diameter runs, deep cover areas, major junctions, access requirements, and testing requirements early. They should then compare conventional designs with alternatives such as profile wall pipe, composite wall pipe, smooth-interior metal pipe, prefabricated risers, prefabricated junctions, or testable double-gasket joints.
Contech corrugated steel pipe (CSP), PVC, and steel reinforced polyethylene (SRPE) products are BABA compliant, and many concrete, polyethylene, and similar sewer pipe products are also likely compliant. However, project teams should verify compliance with each manufacturer for the specific product and project requirements. Please note that aluminum alloy sewer pipe may not currently be BABA compliant.
