India generates over 72,000 million liters of sewage daily, yet only a small portion receives proper wastewater treatment. The country’s groundwater levels have dropped by more than 60% in just two decades in some regions. This alarming situation calls for green water management solutions.
The Jal Jeevan Mission (JJM) was launched by the Indian government to tackle this crisis. Their goal is to provide safe and adequate drinking water to all rural households by 2024. Millions of liters of untreated sewage flow directly into natural water bodies each day and contaminate valuable water resources. Sewage Treatment Plants (STPs) serve as a vital component in preventing this contamination. These plants treat wastewater through physical, biological, and chemical processes to ensure only safe water returns to the environment. The reuse of treated wastewater for irrigation and industrial processes has led to a notable drop in freshwater demand throughout India.
This piece explores how STPs are changing India’s water landscape through multi-stage treatment processes. We’ll get into their effect on rural communities and showcase advanced technologies like SUSBIO ECOTREAT—the most advanced packaged STP in India that provides a future-ready solution for our growing water challenges. Cities will house more than 40% of our population by 2030. This makes effective wastewater management both an environmental and economic necessity.
Why STPs Are Central to Jal Jeevan Mission’s 2025 Vision
The Jal Jeevan Mission’s 2025 vision depends on Sewage Treatment Plants (STPs) as key infrastructure elements. These facilities are the foundations of green water management in rural India. They tackle several challenges at once through systematic wastewater treatment.
Preventing groundwater and river pollution from untreated sewage
Raw sewage poses one of the biggest threats to India’s water bodies. It introduces harmful pathogens, excess nutrients, and toxic chemicals that destroy aquatic ecosystems when it enters rivers and seeps into groundwater. STPs break this cycle by capturing and processing wastewater before it reaches natural water systems.
Modern STPs like SUSBIO ECOTREAT use multi-stage wastewater treatment to remove contaminants. Physical screening removes large debris while sedimentation settles out suspended solids during primary treatment. The secondary treatment breaks down organic matter through biological methods. Final purification happens through advanced filtration and disinfection in tertiary treatment.
Reducing waterborne diseases in rural communities
Rural populations face higher health risks from contaminated water sources. Communities see more cases of cholera, typhoid, dysentery, and other waterborne illnesses without proper sewage management. Villages can significantly lower disease risks in their water supplies by installing STPs.
Biological wastewater treatment plays a crucial role in reducing pathogens. Activated sludge systems and advanced oxidation processes eliminate harmful microorganisms before water returns to the environment. This creates a safety barrier between human waste and community water sources.
Enabling water reuse for agriculture and non-potable use
The most innovative aspect of adding STPs to the Jal Jeevan Mission is water reclamation. Treated water becomes a valuable resource for farming, landscape maintenance, and industrial use—which reduces strain on freshwater supplies.
The complete domestic wastewater treatment turns waste into a sustainable water source. STPs produce safe water for non-potable reuse through carefully designed treatment processes. This circular approach to water management makes solutions like SUSBIO ECOTREAT—India’s most advanced packaged STP—essential for water security in rural communities.
Stages of Wastewater Treatment Process in STPs
Sewage treatment plants clean wastewater through a series of steps. Each step removes specific pollutants and purifies water to meet environmental standards for safe disposal or reuse.
Primary Treatment: Screening and sedimentation
The first step starts with preliminary screening that captures large debris like plastic, paper, and food scraps through screens with spacing between 15-25mm. Water moves slowly through grit chambers where heavier particles like sand and gravel settle down. Large tanks then allow primary sedimentation where gravity separates suspended solids. Heavy solids sink to create sludge while oils and grease float to the surface for removal. This process removes 50-60% of suspended solids and cuts biological oxygen demand (BOD) by 30-40%.
Secondary Treatment: Biological degradation using activated sludge
The next phase targets dissolved organic matter through biological processes. The activated sludge process is accessible to more people and uses microorganisms to consume organic pollutants. Bacteria and other microbes digest organic waste under varying oxygen conditions in aeration tanks. This biological action removes over 90% of remaining suspended solids and reduces BOD substantially. The mixture then flows into a secondary clarifier where activated sludge settles at the bottom while clean water flows out.
Tertiary Treatment: Disinfection using UV or chlorination
The final stage focuses on eliminating pathogens through advanced purification techniques. Chlorination, UV radiation, and ozonation are common disinfection methods. UV treatment achieves 3.4-4.2 log reduction of antibiotic-resistant bacteria at a fluence of 220 mJ/cm². SUSBIO ECOTREAT, India’s most advanced packaged STP, uses advanced tertiary treatment technologies that exceed standard requirements. This makes it a future-ready solution for rural communities.
Sludge Management: Biogas and compost generation
The process thickens residual sludge to increase solids concentration. Dewatering techniques then achieve up to 35% dry matter content. Anaerobic digestion turns organic matter in sludge into biogas with 50-75% methane. This biogas powers electricity generation. The process reduces sludge volume by up to 85% and creates valuable renewable energy.
Reuse and Safe Disposal: Irrigation and landscaping applications
Tertiary-treated effluent helps reclaim water for irrigation and landscaping. STPs across India reuse about 50 MLD of treated wastewater for these purposes. The European Union applies about 50% of its total sludge production to agricultural soils. This provides essential nutrients like phosphorus and nitrogen, reduces synthetic fertilizer needs, and completes the circular approach to wastewater management.
STP Technologies Supporting Jal Jeevan Mission
The Jal Jeevan Mission uses several innovative STP technologies to meet India’s geographical and demographic challenges. These solutions are customized to specific regional needs.
Moving Bed Biofilm Reactor (MBBR) for decentralized systems
MBBR technology offers an ideal solution for small decentralized wastewater treatment because of its compact design and simple operation. The system uses specially designed plastic biocarriers that create a large surface area where microbes can grow. This enables quick organic matter removal without needing extensive infrastructure. MBBR systems can upgrade existing conventional activated sludge performance with minimal changes to host configurations. Delhi Development Authority has successfully used MBBR-based decentralized STPs to treat wastewater from nearby sewers, which helps meet irrigation needs in parks.
Sequencing Batch Reactor (SBR) for variable load handling
SBR technology stands out in managing fluctuating wastewater flows in rural communities. This modified activated sludge process works in time-based sequences instead of separate spaces, making it highly adaptable. SBRs consistently keep BOD levels under 5 mg/L and total nitrogen below 5 mg/L through aerobic, anaerobic, and anoxic treatment phases. These systems cut operating expenses by over 60% compared to conventional methods. The SBR process handles landfill leachate and other challenging wastewaters effectively through its flexible operational parameters.
Constructed Wetlands for low-energy rural setups
Constructed wetlands provide a green, economical alternative for wastewater treatment in rural areas. These systems combine septic tanks with wetland components and achieve impressive removal rates: 87% for TSS, 89% for COD, 93% for BOD, and pathogen removal up to 4.0 log10. Subsurface flow constructed wetlands prevent insect breeding while creating valuable wildlife habitats. Many rural communities now use these natural systems that need minimal maintenance yet produce high-quality effluent suitable for agricultural reuse.
Anaerobic Digesters for biogas generation
Anaerobic digesters turn sewage sludge into valuable biogas with 50-75% methane content, turning waste into renewable energy. Bacteria break down organic matter without oxygen in sealed reactors, producing both biogas and nutrient-rich digestate. You can separate the solid and liquid portions of digestate and use them as animal bedding, fertilizer, or soil amendments. This creates additional revenue streams or helps save costs. Anaerobic digestion helps rural communities handle both waste management and energy needs.
