Wastewater Treatment Plants and the Sustainable Development Goals (SDGs)
Wastewater treatment plants play a crucial role in achieving the Sustainable Development Goals (SDGs) by ensuring the proper treatment of wastewater before it is discharged into the environment. These plants employ different treatment processes, categorized as “primary”, “secondary”, and “advanced”, to indicate the level of treatment provided. Each process contributes to the overall goal of protecting water resources and promoting sustainable development.
Primary Treatment
Primary treatment is the initial stage of wastewater treatment. It focuses on the removal of materials that either float on top of the water or settle at the bottom of processing tanks and chambers. This process aims to remove sedimentation and other large particles from the wastewater.
Secondary Treatment
Secondary treatment involves the use of bacteria to absorb or feed on organic solids present in the wastewater. These solids, known as suspended solids, do not settle naturally. By utilizing bacteria, secondary treatment further purifies the wastewater and reduces its organic content.
Advanced Treatment
Advanced treatment refers to any additional treatment process that improves the quality of the effluent from the secondary treatment. This stage specifically focuses on removing phosphorous and nitrogen nutrients, which can have adverse effects on river quality. By implementing advanced treatment processes, wastewater treatment plants can significantly enhance the overall quality of their effluent.
The Evolution of Blue Plains Wastewater Treatment Plant
The Blue Plains wastewater treatment plant, located in Washington D.C., provides an excellent example of the evolution of wastewater treatment facilities in response to population growth and environmental concerns. The plant has undergone several expansions and upgrades to meet the increasing demands for wastewater treatment.
1938: Primary Treatment Facility
When the Blue Plains plant opened in 1938, it operated as a primary treatment facility. It was designed to serve a population of 650,000 people until the year 1950. At that time, the plant’s operating cost was less than $175,000 per year. The discharge from Blue Plains to the Potomac River was relatively small, measuring less than 100 million gallons per day (MGD).
1959: Addition of Secondary Treatment
As the population and industrial activities in the District and surrounding areas increased in the 1950s, it became evident that primary treatment alone was insufficient. In response, the Blue Plains plant was expanded in 1959 to incorporate secondary treatment with a capacity of 240 MGD. This expansion aimed to improve the quality of treated wastewater before its release into the environment.
1969: Need for Further Expansion
By 1969, the influent flow at Blue Plains had exceeded its design capacity once again. Recognizing the importance of meeting federal regulations, the District Government, along with authorities from Maryland and Virginia, organized a regional conference. During this conference, they agreed to expand the facility further to ensure compliance with the Federal Clean Water Act.
1970-1983: Advanced Wastewater Treatment Facility
From 1970 through 1983, extensive construction took place at Blue Plains to transform it into an advanced wastewater treatment facility. The plant’s capacity was increased to process over 300 million gallons per day. These upgrades significantly improved the treatment levels, aiming to restore the Potomac River to a state suitable for recreational and commercial use.
Blue Plains Advanced Wastewater Treatment Plant Today
The Blue Plains wastewater treatment plant stands as a testament to the importance of continuous improvement and adaptation in the field of wastewater treatment. Today, it serves as a model for sustainable development, aligning with the SDGs by ensuring the proper treatment of wastewater and protecting water resources for future generations.
