Are Wipes Safe for Onsite Sewage Systems?

There has been a lot of chatter in the onsite industry in the last couple of years about the problems that flushable sanitary wipes have been causing. The issues with sanitary wipes extends to communal & municipal collection and treatment systems as well, as operators of these systems have been telling us. Well it seems the industry has listened - a prominent manufacturer of these products in the States is pulling its claim of "flushability" until it can be be substantiated. Check out this article on "Flushability of Wipes" from the Onsite Installer Newsletter for more information.


MMAH Makes Changes to Building Code Licensing Exams

The Ministry of Municipal Affairs & Housing (MMAH) recently announced changes to the way that exams for building code qualifications will be delivered.    Check out this article on "Change to Ontario Building Code Qualification Exam" written for the upcoming OOWA ONSITE publication.

Establishing Vegetative Cover on New Leaching Beds

The Ontario Building Code says that "leaching beds should be protected from erosion" and this usually means planting grass or some other vegetative cover on them, which is sometimes easier said than done. Check out this article on "7 Steps to Establishing Proper Vegetative Cover" from the Onsite Installer Newsletter for a how-to primer on this topic.


Efficacy of Additives

Everyone always wants to know whether or not additives "really" work. While the ORWC hasn't completed any studies on this particular subject, our colleagues at North Carolina State University completed a double-blind study on three septic tank additives and a control substance on almost 50 in-use septic tanks with varying levels of maintenance. Interestingly, no significant positive effects of additive use were observed across all maintenance levels, however some high maintenance sites did show significant treatment effects on sludge depth and scum thickness. A second follow up study to the first one showed that once maintenance was removed as a factor, no positive effects could be attributed to the use of additives.
