The WCOWMA- BC is hosting a Site & Soils Evaluation Field Day on Denman Island, BC on September 21, 2015.

This practical training day is a great opportunity to get hands-on experience evaluating a site, as well as practicing hand texturing and sampling. In the afternoon, students will be review the filing and plan for the site. Installers who have recently completed the Onsite Wastewater Practitioner Training Program will be able to take their new knowledge and apply it in the field. Experienced planners and installers should also consider this opportunity to continue their education.

It is recommended that participants also sign up for the 2-day install training workshop, which takes places on September 22 & 23 at the same site.

The expected outcomes for this training are listed below, and a registration form can be downloaded here. You may register for this hands-on training by fax, email, or online. Please contact the WCOWMA office with any questions you may have.
