Total flexibility for configuring in tight spots!

I have been in the business of installing septic systems for many years and routinely come across challenging situations that require a smaller footprint and/or the need for a weight bearing location. The unique design of the GoodFlow System gives it an H20 rating for installation under hardtop and total flexibility for configuring in tight spots where traditional options simply can’t work.

One of the finest applications in the industry!

The service we receive from Curtech, now GoodFlow is outstanding, not only with the product delivery, but the setup and installations. This system is my go to system for tight installations and traffic load areas. The system is also very accommodating for substituting for conventional installations. I have over 35 years of experience in the design, inspection and certification of thousands of on site wastewater systems and I find GoodFlow’s product to be one of the finest applications in the industry with competitive costs.

Thank you, GoodFlow! You saved my property.

I had an on-going and frustrating dilemma with my well of over 20 years, it needed frequent pumping and ultimately was sinking. I ‘banked on’ Goodflow to do the job. If you want a first-class job done by friendly and competent staff, at a fair price, with excellent results……..give Goodflow the nod; they were the right solution to my problem.

Goodflow saved me from a headache!

My conventional septic system failed and with every septic system we explored, we would need a variance from the Health Department because the system needed to fit in a small footprint and was adjacent to wetlands.  Due to the high liquid storage capacity, the GoodFlow CTL System was the only reliable system that would fit in the small footprint and installed without a variance.
