Septic system life extension:
What steps can maximize the life of a septic tank & drainfield sysem?
How to take care of your septic system - latest septic system maintenance advice for homeowners to get the maximum septic tank life, maximum drainfield life, minimum septic system operating, maintenance, and replacement costs. With rising septic repair prices and changing weather patterns due at least in part to global warming, septic maintenance is even more critical to keep a healthy home and yard and to avoid costly septic system repairs.
Here is our updated septic system maintenance advice in a nutshell.

An Expanded Version of The EPA Septic Care Guide - Ten Simple Steps to Septic System Maintenance
Septic drainfield failures or sewage backups may be more common than some people realize.
As the EPS said in the original and brief article on septic system care, "if your septic tank failed, or you know someone whose did,
you are not alone. As a homeowner, you are responsible for maintaining your septic system.
Proper septic system maintenance will help keep your system
from failing and will help maintain your investment in your home. Failing septic systems can contaminate the ground
water that you or your neighbors drink and can pollute nearby rivers, lakes and coastal waters." - [Original text, U.S. EPA, editing/additions by author]
People normally seem to forget about their septic tank and drainfield until there are odors, slow drains, sewage backups, or sewage coming up in the yard - signs of a septic system problem. You can greatly extend the life of a septic system by taking
care of it. The most basic step in septic system care is to have the tank pumped on schedule. That's far more important than any magic additives, septic helper, or septic chemicals which usually are of little use and sometimes
are downright harmful.
Here are ten simple steps that the US EPA suggested in order to keep your septic system working, with additional comments added by an experienced septic system inspector.
Have your septic system inspected at least every three years. This is a somewhat arbitrary rule of thumb but it's better than never doing anything. [Home buyers should be sure to review our HOME BUYERS GUIDE to SEPTIC SYSTEMS Inspection & Testing -- DF]
Keep other household items, such as dental floss [trivial in volume, but can clog or snag septic pumps, float switches, controls, feminine hygiene products, condoms, diapers, and cat litter out of your system.
Plant only grass over and near your septic system. Roots from nearby trees or shrubs might clog and damage the system. Also, do not apply manure or fertilizers over the drainfield. [See our
article, PLANTS & TREES OVER SEPTIC SYSTEMS for more details --DF]
Keep vehicles and livestock off your septic system. The weight can damage the pipes and tank, and your system may not drain properly under compacted soil. See SEPTIC FIELD FAILURE CAUSES
Keep roof gutters and basement sump pumps from draining into or near your septic system. [And very important, keep surface runoff and subsurface runoff away from the septic tank and drainfield -- DF]
Check with your local health department before using additives. Commercial septic tank additives do not eliminate the need for periodic pumping and can be harmful to your system.
[Actually most septic tank additives don't help, some septic tank additives are highly caustic or toxic and contaminate the environment, some hurt (like yeast), and some or perhaps all (depending on where you live) are illegal to apply -
SEPTIC TREATMENTS & CHEMICALS septic tank chemicals, treatments, additives, reported as intended for extending the septic system life, "Un-Clogging," or "Repair" - Septic Tank Treatment -- DF]
And we add a compund eleventh septic system life extending step:
Improve the septic system: adding a greywater system, separate drywell, adding a septic tank inlet or outlet filter (SEPTIC FILTERS), or adding an aerator to convert the conventional septic tank to an aerobic design will increase the level of effluent treatment and extend drainfield life.
Watch out: adding a septic tank aerator with incomplete design can push solids into and destroy the drainfield. Aerobic septic tanks use multiple chambers to avoid this problem; a retrofit design would typically include an outlet tee filter or separate filtering chamber that, if omitted or not properly maintained is likely to lead to sewage backups or septic system failure.
The U.S. EPA does not regulate septic systems, however, state and local governments do regulate the use of these systems.

tank pumping, field installation, and repair, is at our Septic Systems Home Page.

low-use septic tank pumping & freeze protection in Northern Ontario
(Oct 9, 2014) Keith said:
My tank is seasonal and this year had very little use. Do I need to have it pumped before winter. It is in northern Ontario.
Usually septic tanks are left full all the time.
When a septic system is not in use in freezing weather, it's likely that components not below the frost line will freeze. If the tank is plastic or fiberglass or if it's below the frost line you should be ok. Even if it's higher I'm not sure I'd empty it as frost around the tank exterior could still be a worry.
After all that thinking aloud I'd say I don't know. I would ask my local septic contractors for an opinion. Let me know what they think as what you learn will help others.

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 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.
