Over 35 years septic experience - 5 year warranty
Over 1500 septic systems in the ground!

Our Service Commitment

Committed to Quality...

Grayline has never walked away from a project until the system was functioning perfectly and my customers received full value for their investment.

Grayline Contracting Ltd. designs and installs wastewater septic fields which have been in service over 30 years. For the last several years we have designed and installed state of the art Secondary Packaged Treatment Plants which are the most efficient method to greatly reduce the strength of sewage effluent before it is discharged into the environment. Grayline has always been able to provide an affordable onsite sewage solution which meets or exceeds the customers needs and is compliant with all Provincial and Municipal regulations. We pride ourselves in the protection of the environment first, and delivering a cost effective high quality septic system.

Please choose a location near your property and contact me. I should be able to provide a reference to you from your neighbour.
