Marketing & Social Media

The Marketing Committee is responsible for promoting the mission, goals, and achievements of the Global Water Stewardship. Responsibilities include, but are not limited to; creating t-shirts, banners, pamphlets, brochures, and leave-behind items, preparing marketing and business plans, advertising events, and sharing GWS progress through social media. This group works closely with the Fundraising Committee to promote GWS during public events. Be sure to check out the GWS Facebook, Twitter, and LinkedIn accounts!

Research & Development

This committee leads the charge on discovering new wastewater treatment technologies while making contacts within the industry. Members work to research ongoing advancements in order to provide the most up-to-date, low cost, low maintenance, sustainable systems to the communities GWS serves. The committee reaches out to manufacturers for equipment and material information, as well as for possible discounts or donations for each specific project.


This group assists the winning student design team with final quality control. Members review the submitted solution to ensure the design is functional and feasible. The Project Manager is also responsible for organization and gathering of equipment capital, operational, and maintenance costs. He or she delegates review work to several other GWS committee members and ensures the student team understands any required design changes.

International Programs

This committee was created to serve as the connection between local project contacts and the GWS project team in the US. Amy Work is serving as the local Costa Rica representative for GWS and has been a strong asset for continuing progress in Costa Rica due to the limited time the US team can spend there each year. The committee is actively working to ensure all current projects are moving forward. This includes finalizing designs, obtaining permits or surveys, organizing biogarden construction, or suggesting treatment solutions. Constant communication is key to project success.
