Site & Soil Evaluation/Practical Training

WCOWMA-BC is hosting a two-day continuing education opportunity in Barriere, BC on October 3 & 4. The focus will be on site and soil evaluation with supporting presentations on Flout Technology and on System Piping. The goal of this two day event is to provide both practical and technical information to the trainees.

Site & Soil Evaluation – The site at Barriere offers a unique opportunity to view a variety of soils and their parent materials, while allowing the ability to have trainees participate in presentations in a classroom setting as well. Don’t miss the chance to enhance your skill level by attending one or both training days at the Barriere site.

 Soil texture, make up of sand/silt/clay, don’t count gravel component
 Effect of gravel component
 Where to take sample
 Basic hand texturing procedures
 Trial hand texturing
 Lab testing availability and basic knowledge of lab testing method
 Recognize changes in soil horizons and understand effect on sewage system design.
 Soils logging using various soils logs
 Understand and apply the soil texture triangle.
 Able to determine effluent-loading rate for a soil texture set in Standard of Practice.

Piping Considerations for Onsite Wastewater Treatment – A short presentation will be made on piping considerations for onsite wastewater treatment. It seems simple, however the importance of proper handling, drilling and gluing of the piping component cannot be overlooked.
