Hi Matt,

Thank you so much for the work you have done. The installation of our septic holding tank was seamless. The dirtwork you did was the best I’ve ever seen. You are courteous and prompt and I will definitely use your services again.



We selected Grayline Contracting Ltd. to install a Proflo Secondary Treatment system and an At Grade disposal field for our new home east of Okotoks. Bruce explained the system options and construction process to me on site. Grayline was very mindful of our priorities with the system and the trees that we wanted to ensure were protected on the property near the house. Their installation was completed timely and in a professional manner with no extra charges. We encountered an issue with the system shortly after we moved in on a Sunday morning which was resolved over the phone with Bruce within a few minutes. Grayline sent out a service technician to review the whole system the next day without any cost to us. We would recommend Grayline to anyone who is seeking a quality septic system installation.

Dear Bruce,

Last year I had a septic system installed by your company, Grayline Contracting. I have to say that I have been extremely pleased with this decision to use your services.

First: the system was installed quickly and timely. 

Second: Not only was it timely, the staff took, time, during the busy installation, to explain how the system works as it was being placed in the ground, to not only myself, my father-a retired mechanical engineer. But as well to my 6 year old son and 9 year old daughter as they were quite intrigued as to how this system "takes out the bad stuff and makes it safe for the environment" 

They made the area safe for my kids as we were around during the constructions process. They also made sure we had extra "fill" neatly available to back fill as were informed the soil around the tank will settle the next spring. And they cleaned up the area and you could barely tell that the system had been installed.

I also had Bruce, with Grey line return a year later because we had added a second kitchen and suite onto the house and again they were very professional quick and tidy. 

I have been extremely pleased with their service and their system. 

And the "bad stuff" is safety removed our house :-)

With close to 50 projects completed we have encountered very few problems and those issues were dealt with immediately and without any back charges or disagreements. Bruce Gray is professional and is easy to work with and delivers a great product.

Bruce has been installing septic systems for our rural client’s homes for several years now. He is our   “go to guy” who actually installs all the pieces and is in the trenches on every job. Bruce takes the time with our staff and clients to educate them about the septic process and their own systems. He is a specialist and not a contractor “jack of all trades” which many excavation companies offer. We plan on keeping Grayline Contracting busy this year.

We are the premiere waste water service company in southern Alberta so we see the end results of many septic systems after they have been installed. In our opinion Bruce at Grayline Contracting is one of the top septic contractors for workmanship and customer satisfaction.
