At Granby Composites, we manufacture underground fiberglass tanks whose unique designs and first-class materials perfectly meet the provincial, municipal and environmental standards in septic installation. Our specialized equipment will know how to suit the specific needs of your organization and your facilities.

A septic tank is required where an institution is not served by a public sewage collection and a waste water treatment system. Sanitation and health services represent a major long-term investment for a residence; that is why care must be taken in the purchase, the production and the maintenance of an underground tank. As its proper functioning is essential, needless to say that its structure and its conception must be spotless and impeccable.
