The time it takes for the water to travel through the enhancement wetlands results in nutrient and suspended solids reduction, with the added benefit of providing habitat for wildlife.After the wastewater flows through the enhancement marshes, it is currently pumped back to the chlorine contact basin (Step 7), where it is chlorinated and de-chlorinated before it is discharged into Humboldt Bay. 1-2019-0006. Please join us in protecting and preserving this local wildlife sanctuary and recreation area.Raising Awareness of Wetlands, Wildlife & Wastewater Treatment In the oxidation ponds algae powered by the sun creates OThe surface of the Treatment Wetlands are covered with aquatic plants, like After the wastewater completes its two day journey it continues onward to the Treatment Wetlands are being implemented across the world:

The upgraded UV System equipment will be purchased with Community Development Block Grant (CDBG) funds, which requires this environmental assessment.

Raising Awareness of Wetlands, Wildlife & Wastewater Treatment.
This unique system has been the model for similar facilities worldwide. Currently the system uses chlorine to disinfect and sulfur dioxide to remove the chlorine at two points in the system – before flowing to the enhancement wetlands (Step 8), and before discharge to Humboldt Bay (Step 9). Raising Awareness of Wetlands, Wildlife & Wastewater Treatment Greetings from Friends of the Arcata Marsh. Additional oxygen is supplied mechanically by machines called aerators at times when the City wants to increase oxygen and circulation in the pond.

Thick growth of floating and submergent plants in the six treatment marshes shade the water so algae cannot grow. We were founded in 1989 with the initial task of raising funds to build an interpretive center at the Arcata Marsh and Wildlife Sanctuary, but since then have been responsible for educating the public about the Arcata Marsh. The Arcata Marsh we enjoy today would not exist were it not for Arcata’s pioneering wastewater treatment plant and two important experiments conducted there by Humboldt State University and the City of Arcata. We provide volunteers for school field trips, camps, Take a Child Outside day, and many other events for kids K-12.

The City of Arcata proposes to construct upgrades to the existing Arcata Wastewater Treatment Facility (Treatment Facility, or Facility) to update aging infrastructure and comply with the requirements of the Regional Water Quality Control Board (RWQCB) Order No. The treatment system serves a population of 16,000, as wastewater flows through a series of ingeniously constructed ponds and wetlands. Greetings from Friends of the Arcata Marsh. July 2020 . The idea was soon integrated with several other projects such as the salmon aquaculture project and the alternative waste water treatment project. The Arcata Marsh and Wildlife Sanctuary is home to the City of Arcata’s innovative wastewater treatment facility. Treated effluent is discharged into the Humboldt Bay (Outfall 001) or is circulated into Enhancement Wetlands (Outfall 002) in the Wildlife Sanctuary for further treatment.

The emergent plants (cattail and bulrush) and submergent plants (pondweed and coontail) provide habitat for bacteria and other microorganisms that feed on and further break down the compounds that are in the now-secondary treated wastewater.Wastewater is disinfected to kill pathogens, harmful bacteria, and viruses before discharge into Humboldt Bay (Step 9). This byproduct has historically been one of the major issues with Arcata’s treated effluent.The full scope of the upgrades will be undertaken in two separate phases, and will include the following elements:Phase 2 includes the construction of all the additional facilities needed for the parallel secondary treatment facility, including:The City of Arcata has initiated a Wastewater Treatment Facility Plan and plant improvement project.
FOAM is a small nonprofit organization based in the coastal California city of Arcata, about 275 miles north of San Francisco. This is where the Wildlife Sanctuary portion of the Arcata Wastewater Treatment Plant came in. * The population of the Wiyot was reduced by approximately 93% between 1850 and 1890. See Constituents in Wastewater that Treatment Wetlands RemoveConstituents in Wastewater that Treatment Wetlands Remove Education programs are offered for school, scout and other groups, as well as summer camp programs. Treatment occurs naturally, by allowing the time for plants, algae and bacteria to break down the waste products. Arcata's Treatment Wetlands serve as an effective means of treating wastewater by removing harmful constituents.

It monitors, reports, tests and treats all wastewater, including 55-acres of oxidation ponds and 225-acres of treatment and enhancement marshes which make up the Arcata Marsh and Wildlife Sanctuary. FOAM is a small nonprofit organization based in the coastal California city of Arcata, about 275 miles north of San Francisco. The Treatment Facility provides secondary treatment using natural processes including two oxidation ponds and six wetland treatment marshes.
