Washington On-Site Sewage Association Membership

2020 WOSSA Membership ... What does the survival of your business have to do with being a member of a Professional Association?

… Plenty! Be unique, but don’t stand alone.

Join WOSSA or renew your membership and benefit from the leverage and resources that a professional association can provide to its members. Without a professional association to represent you, your business is subject to things outside of your control: government, lenders and your competition. As a professional association, WOSSA performs many jobs on your behalf, such as state and local advocacy. We also provide industry related legislation support or opposition in Olympia with our lobbyist Tim Johnson. With your support WOSSA can do this much more effectively that you can as an individual.

 As a WOSSA Member you also now have a membership in NOWRA

Now that WOSSA is a Full NOWRA Affiliate, you are entitled to enjoy the full benefits of being a NOWRA member. Here are some of the things NOWRA is doing on behalf of its members.

Representation in Washington D.C. and in Our State

85 million Americans - a quarter of our population - rely on onsite treatment systems instead of public sewer systems, but of the billions of dollars the federal government gives the states to address wastewater treatment, we receive less than 1% of those dollars. This is fundamentally unfair to our interests in a number of ways.

NOWRA believes this has gone on for far too long. Since 2014, we have had an active lobbying effort at both the Congressional and Federal Agency levels. We think more needs to be done at the federal level to secure legislative and policy changes which foster expanded use of onsite and decentralized technology and which can help the industry address the policy, management, and financial issues caused in large part by neglect at the federal level.

Septic Locator

Every NOWRA member receives a free listing on the Septic Locator, the only national, searchable directory of providers of onsite wastewater management services. Once your information is entered in Septic Locator database, you have an opportunity to be found by homeowners and others who are looking for your services. Best of all, your listing is controlled by you -- you can change contact information, services offered and other information in real time. You will receive notification on how to log in to your Septic Locator listing once your data is posted.

Onsite Journal

NOWRA has resumed publication of the Onsite Journal magazine. This 4-color magazine offers useful information about national developments affecting onsite wastewater, reports from state affiliates and industry vendors, and updates on NOWRA programs and services of interest.


NOWRA provides all members with opportunities to have a voice in its affairs. Whether you express that by voting in NOWRA’s Board of Directors elections, participating in our annual meeting, commenting on proposals, volunteering your time on a committee or task force, or simply sharing your views with a board member, NOWRA welcomes and encourages your involvement in our activities.

National Backhoe Roe-D-Hoe® Competition

Held annually, this competition is intended to showcase the skills of contractors and the equipment they operate through a series of timed exercises contestants must perform on a backhoe. NOWRA also sanctions a number of state Roe-D-Hoe® competitions around the country; the state winners are automatically grandfathered into the national finals where they compete against the winner of the open competition.

Equipment Loan Discounts

NOWRA has partnered with Wells Fargo to provide NOWRA members with discounts on interest rates and document fees for equipment purchases in excess of $50,000. Wells Fargo’s Specialty Vehicles Division is offering NOWRA members a quarter percent discount. (25 basis points) off of the prevailing interest rate for purchases of vehicles or related equipment which are financed through their division. As with any loan request, applicants must still qualify for financing under the terms and conditions of the lending authority.. Click here to take advantage of this members only program
