Atlas SWS coordinates septic and onsite wastewater projects from site evaluation and permitting through excavation, tank installation, drainfield construction, and final inspection. The work is completed by appropriately licensed local specialists, with Atlas remaining the project contact for scope, documentation, and follow-through.
This service is built for commercial properties, new construction, engineered systems, precast concrete tanks and vaults, and sites where wastewater work has to fit the existing drainage plan. Residential systems are evaluated when they are part of a larger site, development, or infrastructure package.
Commercial Sites
Commercial and institutional properties often need more than a standard residential tank and drainfield. Atlas SWS supports restaurants, shops, offices, industrial yards, churches, schools, HOAs, and other sites that require larger treatment capacity, grease handling, pump stations, or tighter setbacks around parking, utilities, and buildings.
Typical commercial work includes:
- Conventional and alternative onsite wastewater systems
- Grease interceptors and related pretreatment
- Pump tanks, lift stations, and force mains
- Replacement of failing commercial systems
- Access, traffic loading, and maintenance planning around active sites
New Construction
For builders, developers, and owners starting a new site, the wastewater system should be planned with the building pad, utilities, and stormwater design rather than added after grading is finished.
Atlas SWS can support:
- Site evaluation and soils coordination
- Layout of tanks, treatment units, and drainfields
- Coordination with civil drawings and utility corridors
- Installation sequencing around foundations, paving, and drainage
- Inspection and closeout documentation for the owner and permitting authority
Engineered Systems
When soils, setbacks, flows, or site constraints rule out a conventional system, an engineered design is usually required. Atlas SWS coordinates the field work around those plans so the installed system matches the permitted design.
Engineered-system support may include:
- Coordination with the design professional and permitting authority
- Advanced treatment units and low-pressure or drip dispersal
- Pump-dosed systems and control panels
- Repair or replacement of previously engineered systems
- As-built documentation and inspection support
Permit requirements, designer involvement, and inspection steps are confirmed before work begins. Atlas does not substitute for the licensed soil scientist, engineer, or installer required by the jurisdiction.
Concrete Tanks and Vaults
Precast concrete tanks and vaults are often the right choice for commercial sites, traffic-rated installations, and long-service wastewater structures. Atlas SWS coordinates supply and installation of concrete septic tanks, pump tanks, grease interceptors, and related vaults.
Work may include:
- Precast septic tanks and pump tanks
- Traffic-rated lids, risers, and access structures
- Grease interceptors and pretreatment tanks
- Concrete vaults for valves, meters, or control equipment
- Setting, bedding, backfill, and watertight connections
Tank selection is based on required capacity, burial depth, loading, access, and the approved design.
Drainage Integration
Wastewater and stormwater should not be treated as unrelated site problems. A new tank, drainfield, or vault has to work with existing inlets, pipes, basins, grading, and discharge points. Atlas SWS uses the same inspection-first approach applied to stormwater work so the wastewater scope does not create a new drainage failure.
Drainage integration may include:
- Keeping drainfields, tanks, and vaults clear of concentrated stormwater
- Connecting site piping without mixing sanitary and storm flows
- Repairing inlets, pipes, and outlets disturbed by excavation
- Grading and erosion control around new wastewater structures
- Coordinating stormwater pipe and catch basin repairs when the same excavation exposes both systems
How Work Is Scoped
- Site review — location, existing conditions, drawings, and the problem to be solved
- Permit and design path — confirm what the jurisdiction requires before excavation
- Installation or repair — licensed fieldwork with Atlas coordination and documentation
- Closeout — inspection support, photos, and a clear record of what was installed
If the need is still unclear, start with a site inspection or request a site review. Atlas SWS will identify whether the work is septic, stormwater, or both.
