The process of splitting combined sewer systems into separate lines for sanitary waste and stormwater runoff. Subcontractors are commonly hired for excavation, pipe installation, and tie-in work on municipal or industrial separation projects. Scopes can include bypass pumping, trenchless methods, and service reconnections.
Sewer Separation
Related Terms
Batch Drilling
IndustryA method where multiple wells are drilled to the same depth or stage before moving to the next phase across all wells. Subcontractors should expect high-volume, repetitive scopes with tight sequencing between crews and equipment. Mobilisation efficiency and crew continuity are critical to keeping pace with the operator's schedule.
CNG (Compressed Natural Gas)
IndustryNatural gas compressed and stored at high pressure, used to fuel fleet vehicles and equipment on remote job sites. Subcontractors may need CNG-certified technicians and compliant fuelling procedures when working on CNG infrastructure projects or operating CNG-powered equipment.
Sequencing (construction)
IndustryThe planned order in which construction tasks must be completed before the next trade can begin work. Subcontractors depend on accurate sequencing to schedule crews and avoid costly downtime. Delays in one phase can push back your mobilisation and affect your invoicing schedule.
Maintenance Capital
IndustryFunds spent to keep existing equipment and infrastructure operational rather than expanding capacity. For subcontractors, client maintenance capital budgets directly drive demand for inspection, repair, and servicing contracts. Tighter maintenance capital spending often signals reduced field work volumes ahead.
500-Kv Transmission Line
IndustryA high-voltage power line carrying 500 kilovolts, typically built to move bulk electricity across long distances. Subcontractors on these projects must hold specialised high-voltage certifications and follow strict safety exclusion zones. Work scopes often include tower erection, conductor stringing, and ground grid installation.
Aggregates
IndustryCrushed stone, gravel, and sand used as base materials in construction and oil and gas site preparation. Subcontractors sourcing or hauling aggregates must account for material costs, transport, and site access conditions. Pricing and availability vary significantly by region and project remoteness.
