Iowa septic inspection / testing law: Iowa's Lake Law - TIME OF TRANSFER INSPECTION PROGRAM for SEPTIC SYSTEMS [PDF] Iowa DNR, - retrieved 2018/05/23, original source http://www.iowadnr.gov/Environmental-Protection/Water-Quality/Certification/Time-of-Transfer-Inspectors
Iowa's time of transfer septic system inspection law (SF261) was passed by the Iowa legislature in April of 2008 and took effect July 1, 2009. The new law requires that every home/building served by a septic system have that septic system inspected prior to the sale or deed transfer for the home/building.
The purpose of the law is to eliminate sub-standard or polluting septic systems. A sub-standard septic system is one that has no treatment (secondary treatment) following the septic tank or has a secondary treatment system that has failed. These sub-standard septic systems pose an environmental and public health hazard and require repair.
If you have a septic system with a septic tank AND a secondary treatment system such as a seepage (leach) field, sand filter or other approved device, and it is not creating a public health or environmental hazard, it does not have to meet current code. All inspections must be conducted by an inspector that has been certified by the department.

I live in Sherburne County, old farm house rental. the landlords upgraded in 1996. how do I get the whole system checked and tested? they choose not to.
You can hire a private home inspector who includes septic system visual inspection, component locaiton, and septic drainfield loading and testing in their services. A few plumbers or septic installers or engineers may also offer that service.
Note that in some states septic system inspection, testing, or soil tests such as perc testing must be performed by a licensed expert.

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.
Onsite Wastewater Disposal, R. J. Perkins;
Quoting from Amazon: This practical book, co-published with the National Environmental Health Association,
describes the step-by-step procedures needed to avoid common pitfalls in septic system technology.
Valuable in matching the septic system to the site-specific conditions, this useful book will help you install a reliable system in
both suitable and difficult environments. Septic tank installers, planners, state and local regulators, civil and sanitary engineers,
consulting engineers, architects, homeowners, academics, and land developers will find this publication valuable.
Onsite Wastewater Treatment Systems, Bennette D. Burks, Mary Margaret Minnis, Hogarth House 1994 - one of the best septic system books around, suffering a bit from small fonts and a weak index. (DF volunteers to serve as indexer if Burks/Minnis re-publish this very useful volume.)
While it contains some material more technical than needed by homeowners, Burks/Minnis book on onsite wastewater treatment systems a very useful reference
for both property owners and septic system designers. We refer to it often.

Septic System Owner's Manual, Lloyd Kahn, Blair Allen, Julie Jones, Shelter Publications, 2000 $14.95 U.S. - easy to understand, well illustrated, one of the best practical references around on septic design basics including some advanced systems; a little short on safety and maintenance. Both new and used (low priced copies are available, and we think the authors are working on an updated edition--DF.
Quoting from one of several Amazon reviews: The basics of septic systems, from underground systems and failures to what the owner can do to promote and maintain a healthy system, is revealed in an excellent guide essential for any who reside on a septic system. Rural residents receive a primer on not only the basics; but how to conduct period inspections and what to do when things go wrong. History also figures into the fine coverage.
Grass is Always Greener Over the Septic Tank, Bombeck, Erma: $ 5.99; FAWCETT; MM;
