Solving Septic Failures on Challenging Northern NJ Properties

If you’ve been told your property “can’t support a septic system,” you’re not alone. High water tables, rocky Highlands terrain, and strict lakefront setbacks make traditional concrete systems impossible on many Sussex County lots.
The Norweco Singulair Green solves what standard systems can’t:
- Lightweight HDPE construction fits where heavy concrete tanks can’t access—no cranes tearing up your driveway or retaining walls
- Advanced aerobic treatment produces 95% clean effluent, meeting strict environmental standards for Lake Hopatcong and Culvers Lake properties
- Compact footprint works on undersized lots where conventional drain fields won’t fit
- Freeze-thaw resistant ribbed tank design outlasts cracking concrete in NJ’s acidic soils
We’ve installed Singulair systems on steep lakefronts in Hopatcong, rocky hillsides in Wantage, and “failed perc test” lots across Vernon and Sparta—properties other contractors walked away from.
Complete Norweco Singulair Green Installation Services
Site Feasibility & Soil Analysis
Before we break ground, we assess your property’s soil classification, water table depth, and access constraints. We handle Class I and Class III soil logs, high water table mitigation, and tight-access delivery planning. For lakefront properties in Hopatcong where heavy concrete trucks can’t access the backyard, the Singulair Green’s lightweight design allows us to hand-carry or light-machine the tank into place without destroying your retaining walls.
Engineered System Design & Permitting
Our team provides complete septic engineering and design tailored to your lot’s challenges. We manage NJDEP T-1 permit applications, Highlands Commission approvals, and local health department coordination. You get a system designed for long-term compliance, not just a “pass inspection” shortcut.
Norweco Singulair Green Technology Installation
We install the complete Bio-Kinetic aerobic treatment system—the ribbed HDPE tank, Singulair 206C aerator unit, and Service Pro control panel with remote monitoring. This isn’t a basic septic tank. The aerobic process breaks down waste to 95% clean water before it reaches your drain field, dramatically reducing the risk of field failure and protecting groundwater quality.
Drain Field Construction & Site Restoration
After septic tank installation, we construct the appropriately sized absorption field based on your soil type and daily flow requirements. Our excavation crews grade, backfill, and restore your property to pre-construction condition—we treat your yard like it’s our own, with no surprise damage or hidden cleanup costs.
Regulatory Compliance & Health Department Witnessing
We coordinate all required inspections with your local health department and handle the mandatory witnessing of tank placement and field construction. Your system will be fully compliant with New Jersey Title 7 regulations and ready for occupancy permit approval.

Common Questions About Norweco Singulair Green Systems
How much does a Norweco Singulair Green installation cost in Sussex County?
Costs vary based on soil conditions, system size, and site access, but we provide free flat-rate estimates after a site evaluation. Most residential installations range from $15,000–$30,000 depending on complexity.
Is the Singulair aerator noisy or expensive to run?
The aerator runs whisper-quiet for 30 minutes every hour and uses about as much electricity as a 100-watt lightbulb—roughly $10–$15 per month.
Is the plastic HDPE tank as durable as concrete?
HDPE is chemically resistant and won’t crack during NJ’s freeze-thaw cycles like concrete can. The ribbed design is engineered specifically for acidic soils and shifting ground conditions common in the Highlands region.
Do I need a maintenance contract for a Norweco system?
Yes—New Jersey requires annual maintenance contracts for aerobic treatment systems. Most manufacturers include the first two years, and ongoing service typically costs $200–$400 annually.
How long does installation take?
Most residential Singulair installations are completed in 3–5 days, weather permitting. We coordinate inspections to avoid delays and keep your project on schedule.
Can you install a Singulair system on a lakefront property with limited access?
Absolutely. We’ve installed systems on steep Lake Hopatcong properties where traditional equipment couldn’t reach. The lightweight HDPE tank allows us to use compact machinery or manual placement without damaging your shoreline or existing landscaping.
