Representing Manufacturers of Septic Tanks & Underground Precast Structures

- Established in 1991, the Concrete Precasters Association of Ontario has worked to create and strengthen relationships between our members, in an effort to better our industry and provide a unified voice for the independent manufacturers of septic tanks and other concrete products.

- Our annual conference provides a forum for discussion on current issues affecting our industry, educational seminars on industry topics, and an opportunity to get away from the flurry of day to day business and “talk shop” with like-minded business owners and suppliers.

- Technical, Safety and Marketing committees provide members with tools to take “back to the shop”, to help keep their businesses up to speed and up to code.

- Training courses and workshops keep member’s employees safe and knowledgeable.

- The CPA provides a valuable forum for supplier members to engage directly with owners and decision makers.
