Water Supply Systems &
Infrastructure Services
From submersible well pumps to complex booster stations and atmospheric storage systems, Duncan Water Systems engineers every component of your water supply infrastructure to perform reliably for decades.
Residential & Commercial
Submersible Well Pumps
Engineered for performance, longevity, and energy efficiency in private well systems.
Duncan Water Systems designs and installs high-performance submersible well pumps for residential homes, farms, and commercial properties. We select pumps based on detailed well analysis, required flow rates, total dynamic head, and long-term energy efficiency considerations.
Site-Specific Sizing
We perform pump curve analysis matched to your well's specific yield and drawdown characteristics.
Premium Equipment
We specify and install Franklin Electric, Grundfos, and other industry-leading submersible motors and pumps.
Variable Frequency Drives (VFD)
Available for commercial and high-demand residential applications to optimize energy use and provide constant pressure.
Complete System Integration
Pump, motor, drop pipe, safety rope, check valves, and electrical controls, all engineered as one reliable system.

Key Benefits
High Reliability
Submersible pumps are protected from freezing and surface contamination, offering superior longevity.
Quiet Operation
Installed deep in the well, these pumps operate with virtually no noise at the surface.
Energy Efficient Options
VFD-controlled systems significantly reduce electricity consumption compared to traditional constant-speed pumps.
Low Maintenance
Properly sized and installed submersible systems require minimal service over their 15–25+ year lifespan.
Typical Applications
Private residential wells
Small commercial & agricultural
Irrigation systems
Whole-house constant pressure systems
Well rehabilitation & pump replacement
Residential, Commercial & Industrial
Water Storage Tanks & Atmospheric Systems
Engineered storage solutions for reliable water supply, pressure management, and peak demand handling.
We design and install a full range of water storage solutions, from small residential pressure tanks to large atmospheric storage tanks for commercial and industrial applications. Every system is sized using hydraulic modeling to ensure adequate volume, pressure stability, and emergency reserve capacity.
​
Engineering Considerations:
-
Proper tank sizing based on peak demand and recovery rate
-
Material selection (NSF/ANSI 61 certified where required)
-
Freeze protection, level controls, and overflow design
-
Integration with treatment systems and disinfection
-
Seismic and wind load considerations for large tanks
Hydropneumatic (Pressure) Tanks
Pre-charged bladder or diaphragm tanks for residential and light commercial use. We size tanks properly to reduce pump cycling and extend equipment life.
Atmospheric Storage Tanks
Large volume tanks (polyethylene, fiberglass, or steel) used for peak demand shaving, fire protection reserves, or when well yield is limited. Often paired with booster pump systems.
Constant Pressure Systems
VFD-controlled booster pumps with atmospheric tanks deliver steady pressure without large pressure tanks.

When Atmospheric Storage
is Recommended
Low-yielding wells
Emergency water reserve
Treatment contact time required
High peak demand
(irrigation, commercial)
Booster pump systems
Residential & Commercial
Booster Pump Systems
Engineered constant pressure and high-flow booster systems for homes, multi-family, and commercial buildings.
Residential Booster Systems
We design and install booster pump systems for homes with low incoming pressure from municipal supplies or for properties with private wells that need consistent pressure throughout the house.
​
Constant pressure systems with VFD control
Whole-house pressure boosting
Integration with existing pressure tanks or new atmospheric tanks
Quiet operation with sound-dampening enclosures available
Commercial Booster Systems
For office buildings, schools, hotels, restaurants, and multi-family properties, we engineer packaged booster systems that deliver reliable pressure while meeting code and energy efficiency requirements.
​
-
Multi-pump packaged systems with redundancy
-
Building automation / BMS integration
-
High-efficiency motors and VFDs
-
Domestic water boosting and fire pump systems

Why Proper Booster System Design Matters
Energy Efficiency
VFD-controlled systems can reduce energy use by 30–60% compared to constant-speed pumps.
Pressure Stability
Eliminates pressure fluctuations that damage fixtures and reduce comfort.
System Longevity
Properly sized pumps with soft starts experience far less wear and extend service life significantly.
Code Compliance
We ensure all installations meet local plumbing, mechanical, and energy codes.
