WATER TREATMENT PLANT
THE WATER PLANT DEPARTMENT IS RESPONSIBLE FOR:
DEPARTMENT ACTIVITIES AND SERVICE LEVEL DESCRIPTION:
Water treatment consists of the water treatment plant, a settling pond, 2 pump stations and 1,000,000 and 2,000,000 gallon storage tanks. Water is drawn from Ferry and Geiger Creeks and pumped to a settling pond. It is then pumped to the treatment plant where it is treated, disinfected, pumped to the storage tanks and then gravity fed to the City. The plant is capable of treating 1,400 gallons of water per minute (2,000,000 gallons per day). The City's peak water demand has been as high as 1,500 gallons per minute. The daily consumption ranges from a high of 1.1 million gallons per day for summer use to 300,000 gallons per day for winter use.
The water distribution system (mains and lines) is maintained by the Public Works Department.
The activities of the Water Treatment Department are operated primarily out of the Water Fund, and are financed by revenues collected from the sale of water to utility customers. The City also maintains a Water Reserve Fund, into which funds are deposited for future capital improvements to the water system. The revenues collected through System Development Charges (SDC's) for new water installations are deposited into the Water SDC fund for use in various improvement projects to upgrade and expand the capacity of the water treatment and distribution system.
Prior to 1955 the City of Bandon got its water from Spring Creek and pumped it directly into wooden water lines. In 1955 the City started getting its water from Ferry and Geiger creeks. They also built a 1 million gallon storage tank, replaced the wooden water mains and started disinfecting and controlling the Ph of the water.
In 1982 the City completed the building of its first water plant. They bought 3 used water filters from Roseburg Water District, built a new clarifier and started full water treatment. In 2000 the City completed a full renovation of the Water Treatment Plant to bring it into compliance with the new water treatment laws. The new treatment plant will ensure that the City will be able to meet future city needs and new water treatment rules.
PURPOSE OF THE PLANT
The primary function of the Water Treatment Department is to provide a high quality supply of clean drinking water and a dependable supply of water for fire suppression.
All sources of drinking water are subject to potential contamination by substances that are naturally occurring or man made. These substances can be microbes, inorganic or organic chemicals and radioactive substances. All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. Water treatment is the process of cleaning the water. The City's Water Treatment Plant uses a four step process to treat the water. In the first step alum (aluminum sulfate) is added to the untreated water to make particles like dirt, sediment and other substances in the water coagulate, or stick together. These particles clump together into larger particles called "floc". In the second step, the water enters the settling tank, or sedimentation basin. The floc particles are heavier than water so the settle to the bottom of the tank. During the third step, the water flows through the sand and charcoal filters. In the final step, the water passes through an ultra violet light system to kill any germs, then chlorine is added to the water and to keep it safe in the distribution system as it travels to your tap.
WASTEWATER TREATMENT PLANT
DEPARTMENT ACTIVITIES AND SERVICE LEVEL DESCRIPTION:
The primary function of the Wastewater Department is to operate and maintain the wastewater treatment plant, and ensure compliance with all state and federal regulations related to sewage treatment, disposal, and discharge.
Sewage is collected by a network of sewer lines and seven (7) pump stations throughout the community. When the sewage reaches the plant head works it is run through a pre-treatment (muffin monster) and then into an aeration basin. There it is treated by the activated sludge process. Treated sewage is then run into the clarifier where it is allowed to settle and the supernate is run through a disinfection (UV) system and into the Coquille River. The sludge is pumped into the aerobic digesters and allowed to digest for at least sixty (60) days and then transported by tank truck to a variety of approved sites.
The Wastewater Treatment Plant has a peak design capacity of 3.2 million gallons per day. The plant could be expanded to a maximum average capacity of 1.7 million gallons per day.
The sewage collection system (sewer mains and lines) is maintained by the Public Works Department.
The activities of the Wastewater Department are operated primarily out of the Sewer Fund, and are financed by revenues collected from the sale of sewage treatment services to utility customers. The City also maintains a Sewer Reserve Fund, into which funds are deposited and saved until needed for major plant repairs and improvements. The revenues collected through System Development Charges (SDC's) for new sewer installations are deposited into the Sewer SDC fund for use in various improvement projects to upgrade and expand the capacity of the sewage collection and treatment system.
THE WASTEWATER PLANT DEPARTMENT IS RESPONSIBLE FOR:
The City's original WWTP was constructed in 1970, on the westside of the Riverside Drive. In 1993, the City's facility was upgraded to its current design. The murals were painted by the late local artist Jack Champayne, and maintained by City staff.
PURPOSE OF PLANT:
The Bandon Wastewater Treatment Plant (WWTP) is an integral part of the Bandon Community. It provides treatment and disinfection of wastewater from residences, businesses, and industry to levels specified in the City's National Pollutant Discharge Elimination System (NPDES) Permit (Appendix I), and to levels commensurate with the values of the citizens of Bandon.
The Bandon WWTP not only provides for the immediate protection of public health, but also for the protection of coastal fisheries. Fishing is still an important industry in the Bandon area. Chemicals and microorganisms in a poorly treated discharge can severely impact marine life. Because of the potential damage from a poor quality effluent to shellfish in the Coquille River Estuary, the Bandon WWTP is designated in Class I of the Environmental Protection Agency's (EPA) Design Criteria for Mechanical, Electrical, Fluid System and Component Reliability.
The men and women who manage and support the operations of the Bandon WWTP are charged with an important responsibility. Providing the necessary level of treatment in a cost-effective manner is a reasonable expectation of the citizens and rate payers. The plant represents a significant capital investment of the community and must be operated and maintained to ensure its protections and long life.
SERVICE AREA DESCRIPTION:
The area served by the Bandon plant includes the City of Bandon and its Urban Growth Area. About 1,000 acres of the 2,500 acre service area is currently sewered. The sewered area is expected to increase to about 2,000 acres by the year 2013, the year in which the facility is expected to reach its design capacity.
