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.

Permaculture is the conscious design and maintenance of agriculturally productive systems which have the diversity, stability, and resilience of natural ecosystems. It is the harmonious integration of the landscape with people providing their food, energy, shelter and other material and non-material needs in a sustainable way.

Graham Bell, The Permaculture Way
The Sun photographed by the Atmospheric Imaging Assembly (AIA 304) of NASA's Solar Dynamics Observatory (SDO).
Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.

Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes.To harvest the solar energy, the most common way is to use solar panels.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
