Septic System Design & Installation

Grayline Contracting is committed to providing an affordable, workable onsite sewage treatment solution which meets or exceeds your needs and is compliant with all Provincial and Municipal regulations. Some of our original septic fields have been in service for over 30 years. Since the Provincial regulations changed (2009), septic designs have indicated 90% raised sand mounds or Secondary Treatment plants and  9% conventional pressure distribution buried fields. The Gravity fed systems are almost nonexistent due to regulation compliance issues. For the last several years we have installed a growing number of Packaged Wastewater Treatment Plants. These treatment plants offer the most effective method of reducing the strength of sewage effluent before it is discharged into the environment.
