Advanced Treatment Septic Systems by Long Inc.:


If your property has been turned down for a septic system by your local Health Department, give us a call, we can help you obtain approval for a septic system on your lot!

Norweco has systems in over 70 countries around the world. Long Inc. has developed a network of Soil Scientists, Engineers and support staff that are available to assist with any situation, from system design to ongoing maintenance. The Singulair Green Unit is North Carolina approved and has listings under NSF 40, 46, and 245. The unit, installed in conjunction with the Bio-Film Reactor, and the AT-1500 UV light, can easily meet N.C. TS1 and TS2 standards and is approved in N.C. for residential applications with no primary septic tank required. The Singulair Green is easily installed in difficult areas and capable of processing 600 GPD.

Larger units, installed in precast tanks, are available for flows up to 100,000 gallons per day. The system can be configured for gravity flow, LPP or drip system drain-fields. Lab tests show the Singulair Green system is consistently producing treatment levels of 5-8 PPM TSS and CBOD. The control panel performs local system diagnostics if a problem occurs and can be provided with telemetry if desired. The Singulair Green has an industry leading 3-year warranty and provides a pro-rated lifetime warranty for replacement of the aerator.

The Singulair Green system is installed, with one pipe in, one pipe out, and one electrical connection. The simplicity also makes the Singulair Green unit very cost-competitive in the pre-treat market. Please contact Long Inc. if you have any questions about the company, the product, or any site-specific application issues. We look forward to working with you on upcoming projects.
