Natural Gas System Design
Gas Meter & Distribution Sizing
Proper gas meter and distribution system sizing ensures reliable and efficient supply to all building equipment. Design must account for distance, total load, and pressure drops. In larger buildings, higher pressure gas and regulators may be needed to maintain consistent flow across multiple floors and zones.
Shutoff Valves and Controls
Gas systems require easily accessible manual shutoff valves for safe isolation during emergencies. In larger buildings, automatic shutoff valves enhance safety by triggering during emergencies like seismic activity or fire alarms. Modern gas systems often feature monitoring controls for pressure and flow, with remote shutoff capabilities and regular maintenance crucial for safety.
Gas Ventilation and Exhaust
Gas meters and gas-fired appliances require proper ventilation to ensure safe combustion and prevent gas and carbon monoxide buildup.

Domestic Water System Design
Domestic water systems supply potable water in residential and commercial buildings. Larger commercial systems use booster pumps, recirculation, and efficient heaters to meet demand, ensuring code compliance, performance, and sustainability.
Water Heaters
Properly sized water heaters ensure reliable supply for residential and commercial buildings. Energy-efficient models reduce costs and comply with energy regulations and enhance system performance.
Hot Water Recirculation Systems
Hot-water recirculation systems provide instant hot water, minimizing waste. Advanced controls improve efficiency, while energy codes mandate compliance with energy standards for optimal performance in high-rise buildings.
Water Booster Pumps
Booster pumps ensure consistent water pressure in high-rise buildings. VFD systems and regular maintenance enhance performance, reducing disruptions and ensuring reliable service.

Sanitary Sewer System Design
Sanitary sewer systems in residential and commercial buildings manage wastewater by transporting it to municipal sewer lines or treatment facilities. Residential systems handle household waste from kitchens, bathrooms, and laundry rooms. Commercial systems are more complex, designed to accommodate higher waste volumes from multiple occupants and diverse facilities like restaurants or industrial operations. Proper pipe sizing and venting are crucial to ensure effective flow, prevent blockages, and meet local codes.
Sewage Ejector & Sump Pumps
Sewage ejector and sump pumps remove wastewater and groundwater from below-grade areas. Common in basements, these pumps prevent flooding and ensure proper drainage by lifting waste to the building's main sewer line.
Grease Interceptors
Grease interceptors capture fats, oils, and grease (FOG) from commercial kitchens, preventing them from entering the sewer system. Regular maintenance and proper sizing are essential for compliance with NYC codes and preventing clogs in drainage systems.
Stormwater Management System Design
Roof Drainage
Roof drainage systems, including gutters, scuppers, and roof drains, direct rainwater away from building structures. Proper design ensures water flows efficiently to prevent pooling, leaks, and structural damage, while complying with local stormwater codes.
Drywells and Retention Tanks
Drywells and retention tanks capture and store stormwater runoff, gradually releasing it into the ground or sewer system. These systems help reduce flooding, manage water flow, and meet stormwater regulations in urban areas.
Grease & Oil Management
Grease and oil management in stormwater systems is crucial for parking lots, garages, and industrial sites. Specialized interceptors trap pollutants before they enter the drainage system, ensuring compliance with environmental codes and protecting water quality.

Non-Potable Water Systems Design
Rainwater Collection
Rainwater collection systems capture and store rainwater for non-potable uses like irrigation and flushing toilets. Proper design, including filtration and storage tanks, can reduce water consumption and support sustainability efforts, especially in commercial and urban settings.
Greywater & Blackwater Reuse
Greywater systems recycle water from sinks, showers, and laundry for non-potable uses, while blackwater reuse involves treating sewage for irrigation or industrial purposes. These systems reduce water waste and are increasingly integrated into sustainable building designs.
Irrigation Systems
Non-potable irrigation systems use rainwater, greywater, or treated blackwater to water landscapes and green roofs. Efficient designs minimize potable water use, lower costs, and meet green building standards, crucial for eco-conscious developments in urban areas.

Backflow Prevention
Risk Assessments
Conducting backflow risk assessments identifies potential contamination hazards in plumbing systems. This process ensures compliance with NYC codes, protecting potable water supplies from pollutants and reducing the risk of cross-connection issues in residential and commercial buildings.
Equipment Sizing & Selection
Proper sizing and selection of backflow prevention devices, such as RPZ valves, are critical for ensuring effective protection against contamination. The equipment must be chosen based on system pressure, flow requirements, and regulatory standards to ensure reliability.
Reporting & Documentation
Regular reporting and documentation, including annual testing and maintenance records, are essential for backflow compliance. NYC regulations require accurate documentation to be submitted to the Department of Environmental Protection (DEP) for system approval and ongoing oversight.

Regulatory Compliance
Local and National Standards
Plumbing systems must comply with national standards like the National Fuel Gas Code (NFPA 54) and EPA regulations, as well as local plumbing codes. These standards ensure safety, proper system design, and operational efficiency across gas, water, sewer, and stormwater systems.
NYC DEP Compliance
​The NYC Department of Environmental Protection (DEP) regulates water supply protection, backflow prevention, and stormwater management. Compliance with DEP regulations is critical to safeguarding water quality, including regular testing, documentation, and device approvals, particularly in high-density urban areas.
NYC DOB Compliance
​The NYC Department of Buildings (DOB) enforces plumbing codes related to system design, installation, and maintenance. Gas, water, sewer, and non-potable water systems must meet DOB standards for safety and performance, with inspections required to ensure compliance before occupancy or project completion.
