- Advanced Septic Treatment Systems, Inc, Sedro Woolley, WA Tel: 360-856-0550 , email: SalesTeam-at-trd1000.com - TRD-1000 aerobic treatment system unit. Quoting:
The TRD-1000 revolutionized the concept of a Sequencing Batch Reactor (SBR) for small flow wastewater treatment installations.
The drop-in packaged treatment plant is easily installed in less than a day and produces a quality effulent that exceeds NSF Treatment Standard 40.Certified in 1998 by NSF International to meet all requirements of the Standard 40 testing protocol, ten years later (2008) the TRD-1000 was retested and certified to Standard 40. The system continues to surpass NSF Standard 40 and all other ATU's in it's effulent quality.

This feature-packed aerobic treatment system operates like a small municipal treatment plant.The efficient five-stage HOOT treatment system is designed with these components (numbers correspond to numbers on the illustration at above-left)
1. Pretreatment tank where influent enters.
2. Aeration chamber where oxygen is pumped into the waste water.
3. Clarifier chamber where the clear, odorless effluent rises.
4. Chlorinator where the clear effluent passes through for disinfection.*
5. Holding tank for disinfected* effluent ready for discharge.
6. Extremely quiet, efficient aerator and pump.
7. Unique solid-state HOOT Control Center monitors and controls the system.

Our goal is to provide every participant in the small flow water and wastewater field with the best technical and industry information available." In March 2009 we heard from a homeowner of a five year old Norweco aerobic system who complained of noises and odors - we suggested that the system may not have been properly installed or maintained. We will report here on the resolution of that concern.

- Advanced Onsite Wastewater Systems Technologies, Anish R. Jantrania, Mark A. Gross. Anish Jantrania, Ph.D., P.E., M.B.A., is a Consulting Engineer, in Mechanicsville VA, 804-550-0389 (2006). Outstanding technical reference especially on alternative septic system design alternatives. Written for designers and engineers, this book is not at all easy going for homeowners but is a text I recommend for professionals--DF.
- Builder's Guide to Wells and Septic Systems, Woodson, R. Dodge: $ 24.95; MCGRAW HILL B; TP;
Quoting from Amazon's description: For the homebuilder, one mistake in estimating or installing wells and septic systems can cost thousands of dollars. This comprehensive guide filled with case studies can prevent that. Master plumber R. Dodge Woodson packs this reader-friendly guide with guidance and information, including details on new techniques and materials that can economize and expedite jobs and advice on how to avoid mistakes in both estimating and construction. Chapters cover virtually every aspect of wells and septic systems, including on-site evaluations; site limitations; bidding; soil studies, septic designs, and code-related issues; drilled and dug wells, gravel and pipe, chamber-type, and gravity septic systems; pump stations; common problems with well installation; and remedies for poor septic situations. Woodson also discusses ways to increase profits by avoiding cost overruns.
- Country Plumbing: Living with a Septic System, Hartigan, Gerry: $ 9.95; ALAN C HOOD & TP;
Quoting an Amazon reviewer's comment, with which we agree--DF:This book is informative as far as it goes and might be most useful for someone with an older system. But it was written in the early 1980s. A lot has changed since then. In particular, the book doesn't cover any of the newer systems that are used more and more nowadays in some parts of the country -- sand mounds, aeration systems, lagoons, etc.
