Grayline's owner (Bruce Gray) has been designing and installing onsite septic systems for more than 30 years. Bruce is the person who will quote, install, service and warranty the system. We have been actively involved with the evolution of the new onsite wastewater regulations and the required ongoing training to update and hone our skills in this industry. We are in a very unique situation to be able to draw on 35 years of experience and blend that requisite knowledge into new science based training programs. That blend results in our customers receiving sound advice which will provide a quality based onsite waste water system which will serve them well for decades to come.

We blend this information and add the perspective of 35 years of installation experiences to produce a system which is affordable and effective. The septic system should be easy to maintain and operate efficiently with the end goal being environmental protection.   Learn more...
