In the heart of India’s rural and semi-urban landscapes, where vibrant communities thrive amidst lush fields and bustling markets, access to clean water and effective sanitation remains a pressing concern. With over 60% of India’s population living in villages and small towns, managing wastewater effectively is critical to safeguarding public health and preserving the environment.
Yet, these areas often face unique sewage treatment challenges, from limited infrastructure to financial constraints. At SKF Elixer, we are addressing these issues with innovative wastewater treatment plants, powered by Anaerobic-Aerobic Baffled Reactor (AABR) technology, designed to deliver affordable, efficient, and sustainable sewage treatment plant solutions tailored for rural and semi-urban India.
This blog explores the complexities of wastewater management in villages and small towns, the technologies that overcome these hurdles, and how SKF Elixer’s low-cost sewage treatment systems are transforming sanitation for communities across the country.
Whether you’re a panchayat leader in Rajasthan, a small-town administrator in Uttar Pradesh, or an NGO working in rural development, our insights will guide you toward cleaner, healthier communities.
The Sewage Crisis in Rural and Semi-Urban India
India generates approximately 72,000 million litres of wastewater daily, with rural and semi-urban areas contributing a significant share. Unlike urban centers, these regions often lack centralized sewage systems, leading to instances of open defecation, untreated discharge into rivers, or reliance on poorly maintained septic tanks.
Without access to proper sanitation, results in water pollution in villages that contaminates groundwater and surface water sources. This can affect over 500 million people, causing waterborne diseases like diarrhoea.
For a village with 1,000 households producing 100–150 litres of wastewater per household daily, untreated sewage amounts to 100,000–150,000 litres per day. This can pollute local water bodies, reducing safe drinking water availability and costing communities ₹5–10 lakh annually in healthcare expenses.
The lack of infrastructure, coupled with high installation costs, makes wastewater systems a distant dream for many rural and semi-urban areas. SKF Elixer’s solutions bridge this gap, offering affordable STP solutions for rural India that ensure compliance with Central Pollution Control Board (CPCB) norms.

Key Challenges in Rural and Semi-Urban Sewage Treatment
Sewage treatment in villages and small towns faces distinct obstacles:
- Limited Infrastructure: Most rural areas lack sewer networks, relying on open drains or soak pits that overflow during monsoons, spreading contaminants.
- Financial Constraints: High capital costs deter investment, with traditional STPs costing a lot, which is unaffordable for panchayats with small budgets.
- Space Limitations: Small towns and villages often have limited land, making large treatment plants impractical.
- Skilled Manpower Shortage: Operating complex systems requires expertise, which is scarce in rural settings, leading to maintenance issues.
- Power Availability: Unreliable electricity in villages increases operational costs, with traditional STPs consuming lots of power for a plant.
SKF Elixer’s wastewater treatment plants address these challenges with compact, energy-efficient, and low-maintenance systems designed for India’s rural and semi-urban contexts.
How SKF Elixer’s STPs Overcome These Challenges
Our sewage treatment plants, built on AABR technology, are engineered to deliver robust performance while addressing rural constraints.
Here’s how these systems work:
Preliminary Treatment
Raw sewage contains debris, plastics, and organic solids. Pre-treatment units use bar screens and grit chambers to remove 2–5 kilograms of solids per 10,000 litres, protecting downstream equipment. For an STP, this ensures smooth operation with minimal clogging, ideal for villages with limited maintenance resources.
Biological Treatment with AABR
The core of SKF Elixer’s STPs is the Anaerobic-Aerobic Bio Reactor (AABR), which uses fixed biofilm carriers to promote microbial degradation of organic matter and pathogens. This technology achieves 90–95% reduction in Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD), producing effluent with BOD <20 mg/L, compliant with CPCB norms. AABR’s low energy consumption (30–40% less than conventional systems) saves ₹50,000–₹1 lakh annually for a 50 KLD plant, perfect for power-scarce areas.
Disinfection and Tertiary Treatment
To ensure safe discharge or reuse, AABR STPs usually employ UV disinfection, eliminating 99.99% of pathogens without chemicals. For a 100 KLD plant, this treats 80,000–90,000 litres daily for reuse in irrigation, saving ₹1–2 lakh annually on water procurement in semi-urban areas like Bhopal or Varanasi.
Sludge Management
Sludge, a byproduct of treatment, is processed using compact dewatering units, reducing volume to 50–100 kilograms per day for a 50 KLD plant. The treated sludge can be used as fertilizer, generating ₹20,000–₹50,000 annually for rural communities.
Solutions for Rural and Semi-Urban Areas
Wastewater systems are designed to meet the unique needs of rural and semi-urban India, offering scalability, affordability, and ease of use.
Compact STPs for Villages
For villages with 500–2,000 households, compact STPs require only 20–50 square meters. Using AABR technology, they consume 40% less power, saving ₹30,000–₹50,000 annually. Ideal for rural areas like those in Madhya Pradesh and Odisha, these systems treat 8,000–10,000 litres daily, supporting rural water supply and sanitation goals.
Scalable Systems for Semi-Urban Areas
Small towns with 5,000–20,000 residents need robust solutions. 50–200 KLD STPs handle 40,000–180,000 litres daily, with monitoring for real-time performance tracking. For a town in Gujarat or Kerala, this saves ₹2–3 lakh annually in operational costs and ensures compliance with norms.
Community-Driven Approach
Small towns with 5,000–20,000 residents need robust solutions. 50–200 KLD STPs handle 40,000–180,000 litres daily, with monitoring for real-time performance tracking. For a town in Gujarat or Kerala, this saves ₹2–3 lakh annually in operational costs and ensures compliance with norms.
Benefits of Effective Sewage Treatment
SKF Elixer’s STPs deliver transformative benefits:
- Public Health: Treated water reduces waterborne disease incidence, saving ₹5–10 lakh annually in healthcare costs for a village of 1,000 households.
- Environmental Protection: Prevents 100,000–150,000 litres of untreated sewage daily from polluting rivers, preserving ecosystems in rural areas.
- Cost Savings: Energy-efficient AABR systems save ₹50,000–₹2 lakh annually, with compact designs reducing land costs by ₹1–2 lakh.
- Water Reuse: Treated effluent supports irrigation, saving ₹1–2 lakh annually on water procurement for semi-urban communities.
