About Drainage Masters!

Drainage Masters became a licensed general contractor in October 1996 and was established as a sole proprietorship, Drainage Masters North West Registered. Drainage Masters was formed by Steve and Seth Kenworthy, father and son. We are licensed, bonded and insured in both Oregon and Washington. In January of 2009, we incoroporated as a limited liability company and became Drainage Masters LLC. The only share holders being Steve and Seth Kenworthy.

Steve had a 30 year background in civil engineering technology (not an engineer). The last 23 years of that career was in storm water management for the City of Portland. Steve's extensive background includes every dimension of managing surface and groundwater including soil types and drainage characteristics, permitting and bureaucratic issues, materials and construction techniques, water quality, environmental impacts and mitigation, and alternative techniques of surface and groundwater management. Not all drainage or water management projects are complicated. But whether they are or not, you can be sure that Drainage Masters can handle it.

Seth left a promising career in the hardwood lumber industry to apply his enthusiastic work ethic and technical capabilities to his own family owned and operated business. Since the beginning of Drainage Masters in 1996, Seth has proven his abilities to understand the often complex technical details of solving drainage problems and of effectively and efficiently managing every project we do. The remainder of our crew are skilled full time permanent employees. Our professional and courteous office staff are ready to assist you with your drainage needs.
