A sewage treatment plant is a facility where sewage is treated before it is discharged into the environment. Sewage treatment involves the removal of contaminants from wastewater and household sewage. It is important to treat sewage because it can contain harmful bacteria, viruses, and other pollutants that can cause disease.

Sewage also contains nutrients that can lead to the growth of algae and other aquatic plants. If sewage is not treated, it can pollute rivers, lakes, and coastal areas. There are several different types of sewage treatment plants, but all of them use some combination of physical, chemical, and biological processes to remove pollutants.

A sewage or wastewater treatment plant is a facility where wastewater is treated before it is discharged into the environment. Wastewater includes sewage from toilets, showers, and sinks as well as stormwater runoff.

Sewage treatment plants come in many different sizes and configurations, but all have the same basic purpose: to remove contaminants from wastewater so that it can be safely released into the environment.

There are three main steps in sewage treatment: primary, secondary, and tertiary.

1. Primary treatment involves removing large solids from the wastewater. This is typically done by screening or sedimentation.

2. Secondary treatment removes smaller particles and dissolved substances from the wastewater. This is usually done with biological processes like aeration and activated sludge.

3. Tertiary treatment further cleans the water by removing remaining pollutants. This can be done with techniques like filtration, disinfection, and ultraviolet light.

Sewage Treatment Plant Process Steps

The process steps of a sewage plant typically involve several stages to effectively treat wastewater.

1. Preliminary Treatment:

Removal of Large Debris: Incoming wastewater passes through screens or grates to remove large objects like sticks, rags, and plastics.

2. Primary Treatment:

A settling tank holds wastewater for heavier solids (sludge) to settle at the bottom, forming a layer. Operators skim off lighter materials like oil and grease from the surface.

3. Secondary Treatment:

Biological Treatment: The remaining wastewater undergoes biological treatment to remove organic pollutants. This often employs methods like activated sludge, trickling filters, or other biological reactors.

Trickling Filter: During this process, we trickle wastewater over a bed of rocks or plastic media. Microbe on the media break down organic matter.

4. Tertiary Treatment:

Additional Filtration: This step involves further filtration to remove fine particles and impurities. It may include sand filtration or microfiltration.

5. Disinfection:

Chlorination or UV Treatment: To kill or inactivate harmful viruses remaining in the treated water.

6. Sludge Treatment:

Anaerobic Digestion or Sludge Digestion: The sludge from the primary clarifier tank undergoes additional treatment. This process breaks down organic matter and yields biogas.

Dewatering: We then dewater the digested sludge to reduce its volume.

7. Effluent Discharge:

Release or Reuse: They discharge the treated water (effluent) into a receiving body of water (river or ocean) or may reuse it for irrigation.

8. Monitoring and Quality Control:

They conduct regular testing and analysis to ensure that the effluent meets regulatory standards for water quality.

9. Oil and Grease Removal:

In this step, we employ physical processes like skimming or chemical methods. They aim to further remove any residual oil and grease from the water.

Keep in mind that these processes can differ depending on the design of the sewage treatment plant and the technology chosen by the manufacturer. Local regulations and environmental factors also play a role in shaping the treatment process.

The Benefits of a Sewage Treatment Plant

A sewage treatment plant is a facility where wastewater from homes and businesses is treated before it is discharged into the environment. Wastewater contains pollutants that can be harmful to human health and the environment.

Sewage treatment plants remove these pollutants from wastewater so that it can be safely discharged into the environment. Treatment of sewage at a treatment plant also reduces the volume of sewage that must be disposed of in landfills.

There are many benefits to using a sewage treatment plant, including:

- Reduced pollution of waterways and ground water

- Protection of public health

- Reduced stink and odours from untreated sewage

- Less need for landfill space

Sewage Treatment Plant Maintenance

Sewage treatment plants remove pollutants from wastewater using physical, chemical, and biological processes. Physical processes remove solids from the water using screens or filters. Chemical processes remove dissolved pollutants using chemicals such as chlorine or alum. Biological processes use bacteria and other microorganisms to break down organic pollutants.

After the wastewater has been treated, it is discharged into a receiving water body such as a river, lake, or ocean. The receiving water body may also be used for irrigation, drinking water supply, or recreational activities such as swimming and fishing.

To protect public health and the environment, it is important to properly maintain sewage treatment plants. regular maintenance can help ensure that sewage treatment plants are operating efficiently and effectively

The Evolution of Sewage Treatment Plants in Delhi

The inception of sewage treatment plants in Delhi dates back to the establishment of New Delhi in 1938. At that time, they established an 82 million liters per day (mld) capacity Sewage Treatment Plant (STP) in Okhla. Over the years, there was a substantial augmentation in capacity, reaching 164 mld by 1956.

Subsequently, they constructed additional STPs at Coronation Pillar (55 mld) in 1957 and at Keshopur (55 mld) in 1960. The sewage water treatment capacity skyrocketed from 273 mld in 1961 to an impressive 1273 mld in 1993. Currently, the total capacity of sewage treatment plants in Delhi stands at a staggering 2330 Million Liters Per Day.

Extensive Sewerage Network

Delhi currently features a well-organized gravity collection sewerage system. This system includes an extensive network of branch, intercepting, peripheral, and trunk sewers, covering around 6000 kilometers. According to the Delhi Jal Board, there exist twenty-eight primary trunk sewers. They range in size from 700 millimeters to over 2400 millimeters in diameter, collectively spanning around 140 kilometers in length.

Pumping Stations: The Backbone of Sewerage Management

Delhi relies on 36 major pumping stations, with capacities ranging from 6 mld to an impressive 455 mld. Historically, the focus was primarily on providing clean drinking water to both urban and rural areas.

Unfortunately, the growth in sewerage facilities did not parallel the rate of sewage generation. Even today, the sewerage system covers only around 60% of Delhi's population. To address this, they have divided Delhi into six zones:

1. Rithala
2. Coronation Pillar
3. Keshopur
4. Okhla
5. Trans Yamuna
6. Outer Delhi

Expanding Horizons: Sewage Infrastructure in Urban Extensions

Apart from the established zones, newer urban extensions in Delhi/NCR like Narela, Pappan Kalan, Najafgarh, Ghitroni, Vasant Kunj, Mehrauli, and Sarita Vihar have seen the establishment of sewage treatment plants. As of December 2003, Delhi houses STPs at 17 different locations, collectively boasting a treatment capacity of 2330 mld (512.5 mgd). Plans are underway to further increase this capacity to 3389 mld by augmenting existing treatment plants and establishing new ones.

Segmentation of Sewerage Treatment

The Delhi Jal Board classifies the status of the sewerage treatment system based on various categories of inhabitants:

i) Planned Colonies: Approximately 40% of the population residing in planned colonies benefit from a fully developed sewerage system.
ii) Unauthorized-Regularized Colonies:
iii) Resettlement Colonies:
iv) Urban Villages:

This segmentation plays a crucial role in strategizing and organizing further developments in the sewerage infrastructure.
