Markets We Serve

---

SJS Engineering provides professionally engineered septic system solutions across a wide range of markets, from individual residential properties to large-scale commercial, institutional, and environmentally regulated developments. Each market presents unique technical, environmental, and regulatory challenges, and our team applies a market-specific engineering approach to ensure compliance, constructability, and long-term system performance. 

Our experience across diverse project types allows us to anticipate approval requirements, coordinate effectively with agencies, and deliver septic systems that function reliably within real-world constraints.

Residential septic projects require careful engineering to balance soil conditions, lot size, water table, grading, and regulatory setbacks, particularly in South Jersey and older suburban developments.

SJS Engineering provides complete residential septic services, including:

• New single-family home septic systems 
• Replacement of failing or non-compliant systems 
• System expansions for bedroom additions 
• Septic design for constrained or non-conforming lots 
• Flag lots, easements, and shared access conditions 
• High water table and poor soil mitigation strategies
   

Our residential designs range from conventional gravity systems to advanced treatment and pressure-dosed systems, depending on site conditions and regulatory requirements. We manage the entire process, from feasibility and permitting through installation and final approvals, ensuring homeowners receive a compliant, long-lasting system.

Commercial septic systems demand a higher level of engineering due to increased hydraulic loading, variable occupancy, and stricter regulatory oversight. These systems must be carefully sized, designed, and permitted to support ongoing operations without failure. 

SJS Engineering supports a wide range of commercial applications, including:

• Retail and mixed-use developments  
• Restaurants and food service facilities  
• Office and professional buildings  
• Warehouses and light industrial facilities  
• Hospitality and assembly uses
   

Our commercial septic engineering services include flow calculations, system capacity analysis, pretreatment considerations, advanced treatment technologies, and phased system planning. We coordinate closely with health departments and municipal reviewers to ensure systems are approved, constructible, and operationally reliable.

Institutional septic systems often serve schools, municipal buildings, religious facilities, and public-use sites, requiring robust designs capable of handling peak flows, seasonal usage, and long-term durability.

SJS Engineering provides septic engineering for:

• Educational facilities  
• Houses of worship  
• Municipal and government buildings  
• Community centers and recreational facilities  
• Healthcare and assisted living facilities
   

These projects frequently involve multiple reviewing agencies, public funding requirements, and heightened accountability. Our team prepares thorough engineering documentation, coordinates approvals, and manages installation to ensure systems meet both regulatory and operational expectations.

Projects within the New Jersey Pinelands and other environmentally sensitive areas require a specialized understanding of ecological protections, nutrient limits, and land use restrictions.

SJS Engineering offers deep expertise in:

• Pinelands Commission septic approvals 
• Nitrogen-reducing septic system design 
• Advanced treatment technologies 
• Environmentally sensitive site planning 
• Compliance with the Pinelands Comprehensive Management Plan (CMP)
   

We design systems that protect groundwater and surrounding ecosystems while allowing responsible development on constrained parcels. Our experience working directly with Pinelands reviewers helps streamline approvals and avoid unnecessary delays.

Not all projects fit neatly into conventional septic categories. SJS Engineering specializes in non-standard, high-capacity, and technically complex systems where off-the-shelf solutions are not sufficient.

These projects may include:

• High-occupancy facilities 
• Phased developments 
• Systems requiring redundancy and monitoring 
• Sites with poor soils or shallow groundwater 
• Retrofits for aging or failed infrastructure
   

Our engineers evaluate hydraulic loading, treatment requirements, redundancy, maintenance access, and lifecycle performance, delivering engineered systems that meet both regulatory and practical needs.

In addition to end-users, SJS Engineering regularly works with:

• Developers and builders 
• Architects and land use attorneys 
• Municipal engineers and boards 
• Environmental consultants
   

We integrate septic engineering seamlessly into broader site development efforts, providing clear documentation, responsive revisions, and professional representation throughout the approval process.

Regardless of market type, every SJS Engineering project includes:

• Site-specific engineering analysis 
• Full regulatory coordination and permitting 
• Constructible, field-verified designs 
• Installation and construction management 
• Final approvals and documentation
   

From straightforward residential systems to the most regulated environmental sites, SJS Engineering delivers septic systems that are engineered, approved, built, and trusted.
