Arcata Marsh overview. The Arcata Wastewater Treatment Plant is responsible for the treatment of the sewage for the city of Arcata. The Arcata Marsh and Wildlife Sanctuary is a part of the system that cleans our waste in preparation to be released back into the water cycle. The system as a whole is the wastewater treatment plant (WWTP). The Arcata Wastewater Treatment Plant personnel maintain 11 wastewater pump stations as well as all of the equipment, motors, and pumps associated with the plant. They also are responsible for the operation and maintenance, of the 55 acres of oxidation ponds and 154 acres of treatment and enhancement marshes. The Arcata Marsh and Wildlife Sanctuary is a constructed wetland and is part of the Arcata Wastewater Treatment Plant. This use of constructed wetlands is what separates the Arcata Wastewater Treatment Plant from other Wastewater Treatment Plants. The first treatment plant was built in 1946 and discharged unchlorinated primary treated wastewater into the bay.

Wangari Maathai in 2006
As long as there is no trust and confidence that there will be justice and fairness in resource distribution, political positioning will remain more important than service.

Sharing knowledge to build rich, sustainable lives.
Appropedia is the site for collaborative solutions in sustainability, poverty reduction and international development through the use of sound principles and appropriate technology and the sharing of wisdom and project information. It is a wiki, a type of website which allows anyone to add, remove, or edit content. Registration is encouraged but not required for contributors.

Appropedia has been described as an "appropriate technology wiki," but it is much broader than that - it is a green wiki, and a wiki for all matters of international development and aid. But most importantly, Appropedia is an open site for stakeholders to come together to find, create and improve scalable and adaptable solutions. For more about our motivation, see Appropedia:Mission.

To create a new project page, first browse the project articles and subcategories below for examples and check for possible collaboration opportunities, such as articles similar to what you're considering writing. If you are looking for ideas for your own project, check out our suggested projects. It is highly encouraged to tag your projects with their status -- you can do this with a few templates. Be Bold!
