I am pleased to inform you that after years of planning, study, and review,King County now has an approved Regional wastewater Services Plan (RWSP).
RWSP 2004 Update Report Available
Go to Library

Dear Friend,
I am pleased to inform you that after years of planning, study, and review, King County now has an approved Regional Wastewater Services Plan (RWSP). Having an approved plan is good news for this region because we can finally begin to build the extra capacity we need to meet the demands of rapid population growth (check out the tutorial ). And just as importantly, we can meet these demands while protecting public health and our valuable water resources. The RWSP outlines a number of important projects and programs that King County will implement over the next 30 years, and work is already well underway. For example, we recently completed a comprehensive process to find a site for the new Brightwater Treatment Plant , and we are busy improving the conveyance system in the north end. Thank you for your involvement to date in helping us develop the Regional Wastewater Services Plan. I encourage you to contact us to continue your involvement by signing up for our mailing list to receive information about upcoming meetings and workshops and to offer your comments and suggestions about RWSP projects and programs.

Primary treatment of wastewater
Here's a step-by-step guide describing what happens at each stage of the treatment process and how pollutants are removed to help keep our waterways clean. This information is courtesy of the Greater Vancouver Regional District. The Primary Treatment Process 1. Screening: Wastewater entering the treatment plant includes items like wood, rocks, and even dead animals. Unless they are removed, they could cause problems later in the treatment process. Most of these materials are sent to a landfill. 2. Pumping: The wastewater system relies on the force of gravity to move sewage from your home to the treatment plant. So wastewater-treatment plants are located on low ground, often near a river into which treated water can be released. If the plant is built above the ground level, the wastewater has to be pumped up to the aeration tanks (item 3). From here on, gravity takes over to move the wastewater through the treatment process. 3. Aerating:

Significant Points
  • Employment is concentrated in local government and private water, sewage, and other systems utilities.
  • The completion of an associate degree or 1-year certificate program is increasingly becoming an asset.
  • Operators must pass exams certifying that they are capable of overseeing various treatment processes.
  • Job prospects will be good for qualified individuals because the number of applicants in this field is normally low.
Nature of the Work About this section Back to Top Clean water is essential for everyday life. Water treatment plant and system operators treat water so that it is safe to drink. Liquid waste treatment plant and system operators , also known as wastewater treatment plant and system operators, remove harmful pollutants from domestic and industrial liquid waste so that it is safe to return to the environment.

Specializing in remediation solutions for condominium complexes, parks, golf courses, commercial, industrial, mining and agricultural applications. uses a range of microbial probiotic products that are suitable for the bioremediation of terrestrial, wetland, marine, farm land and industrial areas and is specifically suited to the restoration of natural ecological environments. The pace of the Bioremediation Industry has moved quickly. From the discovery that natural indigenous microbes had the ability to remediate pollutants, to the identification, isolation and commercial production of viable products, it continues to progress. Manufacturers are now able to isolate and mass-produce standardized bacteria and fungi in dry endosporic (dormant) state, a tremendous advancement from the 1st generation liquid formats. Recently, traceable scientific studies for these new, standardized, CFU count microbial products have been conducted and demonstrate the efficacy of microbes for the safe remediation of numerous contaminants.

Wastewater Treatment Principles and Regulations
Karen Mancl Sewage is the wastewater released by residences, businesses and industries in a community. It is 99.94 percent water, with only 0.06 percent of the wastewater dissolved and suspended solid material. The cloudiness of sewage is caused by suspended particles which in untreated sewage ranges from 100 to 350 mg/l. A measure of the strength of the wastewater is biochemical oxygen demand, or BOD . The BOD measures the amount of oxygen microorganisms require in five days to break down sewage. Untreated sewage has a BOD ranging from 100 mg/l to 300 mg/l. Pathogens or disease-causing organisms are present in sewage. Coliform bacteria are used as an indicator of disease-causing organisms. Sewage also contains nutrients (such as ammonia and phosphorus), minerals, and metals. Ammonia can range from 12 to 50 mg/l and phosphorus can range from 6 to 20 mg/l in untreated sewage. Sewage treatment is a multi-stage process to renovate wastewater before it reenters a body of water, is applied to the land or is reused. The goal is to reduce or remove organic matter, solids, nutrients, disease-causing organisms and other pollutants from wastewater. Each receiving body of water has limits to the amount of pollutants it can receive without degradation. Therefore, each sewage treatment plant must hold a permit listing the allowable levels of BOD
