The Onsite Institute's missions are to –


Provide quality education to landowners, homeowners, restaurants, businesses and entrepreneurs enabling them to connect with the most appropriate solutions to meet their onsite system (septic system) and greasetrap performance needs.


Empower current or future onsite system owners to make informed decisions.


Provide quality education to onsite professionals (installers, pumpers, O+M+M providers and regulators) delivering an understanding of emergent technologies, strategies, practices and tools to extend the functional life of onsite systems and greasetraps.


Help manufacturers introduce new technologies to regulators, permitting entities and consumers for the purposes of bringing better methods and practices for environmental stewardship into widespread use.


In all these regards, if we find a technology or tool that we think could find beneficial and practical use in your tool box, we will tell you.



Everything Begins With Understanding
Understanding the site's and system's conditions is the first step to solving problems and implementing solutions. Restoring existing systems presents one set of challenges; siting and installing new systems brings another set. Longterm operation, maintenance and management (O+M+M) are critical components of system ownership for all systems. Because they are so important, we will start there.


Without O+M+M, Failure is Assured

Before you put anything into your onsite system, you should plan to do all you can to protect the absorption area, the most delicate and most expensive component of the system to repair. This may also be called the leachfield or bed, drainage area, or simply "drainage." This is a constructed area through which the effluent (the liquid from the treatment tank) moves. After leaving the tank, the effluent passes through perforated pipes into and through a layer of coarse aggregate (crushed rocks). Sometimes it must pass through an additional layer of fine aggregate (sand) before entering the site's natural soil.


Delivering the cleanest effluent to the absorption area is, by far, the most important thing you can do for your system.  Best of all, it is relatively easy to do!


No matter how old your system, ONLY GOOD THINGS will result

from initiating proper O+M+M  procedures now!


Gravity does a pretty good job of separating the solids and liquids in treatment tanks and greasetraps, but when it comes to reducing the accumulation of organic solids in tanks and grease in greasetraps, nature needs some help.
