As a member of the CWA you will have access to a wide range of benefits and join a network of constructed wetland professionals leading the development of new technologies and influencing decision making related to the profession.

Membership of the CWA is open to individuals and organisations involved in the design, installation, servicing, research, regulation and use of constructed wetlands. Members who design, install and service constructed wetlands can apply to become accredited. Accreditation provides a robust, independent, professional recognition of an accepted standard and quality assurance.

Membership categories start with individual, student and retired memberships for academics, researchers or those who have a general interest in constructed wetlands at an individual level.

The CWA also has corporate membership categories for businesses, charities, non profit-making organisations (NPO), academic institutions and the public sector (e.g. regulators). These memberships are divided into those with a turnover above £10M and those with a turnover below £10M.

Members pay an annual membership fee. The level of fee will be approved by Members at the Annual General Meeting upon a recommendation from the CWA committee. (The CWA committee will have discretion to levy reduced rates in special cases). See below for a full list of benefits and associated subscription fees.
