​​​​​WOSSA Conference Roe-D-Hoe
Nearly everyone attending this year's conference was able to witness WOSSA’s Roe-D-Hoe. This year's class scheduling allowed all those in attendance to participate or view this exciting machine operator skills competition. Our thanks goes out to A Advanced for organizing the event, and to NC Machinery for providing the necessary equipment to hold the event. 

Although the 2017 Conference “Going the Distance” is in the rear view mirror, many of the themes are still evident in the economy in Washington. Our program this last year had some great highlights with our Keynote speaker, Ellen Rohr – “Business Uncomplicated” and her popular breakout session on the importance and creation of a business plan. The technical sessions of the conference program expanded to include some new approaches in each of our industry segments and added new elements to support business owners with current information on DOT inspections, insurance costs and coverage along with ideas on taking advantage of opportunities (and mistakes to avoid) growing your business in an economy that is heating up.

Our legislative lobbyist, Tim Johnson updated both our efforts in Olympia and outlined a new attack on our industry by citizen political activist groups like COOMWA (Citizens Opposed to Onsite Sewer System Management in Washington) and CAPR (Citizens Alliance for Property Rights) that piled on to several bills that would have very badly impacted our industry.

This year’s conference also saw the biggest increase in new exhibitors in recent years, and the fundraising auction to support our WOSSA legislative efforts and the Scholarship program in 2017. With $20,000 in scholarships being awarded to successful applicants, this will surpass all of our previous scholarship levels since the beginning of the program.

We have included contact information for all of the exhibitors that were at the Conference and encourage you to reach out to them for your equipment, technology and supply needs. Doing business with the companies that support the industry is just good business. Looking forward to a growing economy and thinking about how you will succeed in “Going the Distance”, let us know at WOSSA what you need and how we can help!
