GWS is developing final design engineering documents for Piedras Blancas and Bahia Ballena utilizing the WEF/CSWEA Student Design Competition. In general, the solution approach should be to construct a centralized treatment system with a complete collection system, and have it be a low cost/low maintenance solution that’s viable for the community to sustain and operate. Our professionals will mentor the students to come up with innovative solutions for the project and present their solution at the Design Competition held each Spring at the CSWEA Education Seminar.
GWS selects the design that best solves the sanitation solutions in the community. The winning team works with the CSWEA professionals to finalize design and associated estimates for operation and maintenance. During the next trip to the community, the winning team is invited to work with Global Water Stewardship and the local communities to help implement the final design.
GWS members are looking to develop a long term wastewater solution utilizing our student design competitions with the graduate students from University of Wisconsin, University of Illinois, and other student chapters within CSWEA. GWS members were able to speak with school faculties to allow the students to develop a design as part of a course that would receive credits. This will improve student participation considerably, and offer GWS a wider variety of solutions to choose from for implementation.
The 2015 winning design for Piedras Blancas is being turned over to a Costa Rican Engineer to finalize and submit for permitting. The Bahia Ballena problem statement was developed for the 2016 Student Design Competition.
GWS is working with the Ministry of Water (AyA), local water authority (ASADA) and local NGOs and municipal leaders to implement our solutions. Use of the Costa Rican labor programs will allow for inexpensive construction. In addition, we are helping to educate the people and children of the communities we are serving about the risks of untreated wastewater and benefits of improved sanitation. Water professionals that have experience running wastewater treatment systems are encouraged to become involved and to help with startup and operations training of the systems.
