modern wastewater treatment technologies to improve inefficient sewage treatment plant
What It Feels Like to Live Near an Inefficient Sewage Treatment Plant (STP)?

Living near an inefficient sewage treatment plant (STP) is a reality for many urban dwellers. Ideally, a well-functioning STP efficiently treats wastewater, ensuring that the surrounding environment remains clean and free from unpleasant effects. However, when an STP operates inefficiently, it can turn into a nightmare for nearby residents, causing serious environmental, health, and lifestyle disruptions.

Unfortunately, India experiences the same scenario. Out of the total built STPs in India, 70% of them struggle with inefficiencies. Also, even 60% of India’s total sewage is still diverted into mainland water bodies without getting treated.Fat oil and grease management becomes even more critical in such cases to prevent clogging and system failure.

Contact us to learn how we can assist in building effective and sustainable wastewater treatment systems.Let’s explore what it is to live near an inefficient Sewage Treatment Plant.

  1. The Constant Odor Problem- Living 24×7 near a gutter

One of the most immediate and unbearable consequences of an inefficient STP is the persistent foul odor. When wastewater is not properly treated due to poor aeration, inadequate biological activity, or overloaded systems, it emits strong smells of hydrogen sulfide (rotten egg smell), ammonia, and other putrid gases.Improper disposal of fats oils and grease (FOG) also adds to these odor issues.

It gives you a feeling of living near a gutter 24×7.

Residents living near such STPs often struggle with:

  • A lingering stench that makes it impossible to enjoy outdoor spaces.
  • Discomfort inside homes, even with closed windows.
  • Frequent headaches and nausea due to exposure to malodorous compounds.
  1. Health Hazards and Airborne Pollutants

An inefficient STP not only smells bad but can also pose serious health risks. The release of volatile organic compounds (VOCs) and bioaerosols can lead to:

  • Respiratory issues such as asthma, bronchitis, and irritation of the throat and eyes.
  • Higher incidences of infections caused by airborne pathogens.
  • Stress and mental fatigue due to prolonged exposure to unhygienic conditions.

Imagine, you are compelled to wear the mask while coming to your home !!

  1. Water Pollution and Groundwater Contamination

If an STP is not treating wastewater effectively, it may discharge untreated or partially treated sewage into nearby water bodies or seep into the groundwater. This leads to:

  • Water pollution: Rivers, lakes, or ponds receiving improperly treated sewage become breeding grounds for harmful bacteria and toxins.
  • Groundwater contamination: Leaks from faulty STP infrastructure can introduce fats oils and grease, nitrates, phosphates, and pathogens into the water table, affecting local wells and drinking water sources.
  • Eutrophication: The excess nutrients discharged into natural water bodies promote excessive algae growth, depleting oxygen levels and killing aquatic life.

Govt. spending crores for the people, but it gets turned against them!!

  1. Insect and Pest Infestation

The presence of untreated sewage and sludge accumulation attracts insects and pests, making life miserable for residents. Common problems include:

  • Mosquito breeding: Stagnant water due to inefficient sewage treatment plant creates an ideal environment for mosquitoes, increasing the risk of diseases like dengue and malaria.
  • Increase in rodents and flies: The organic waste in untreated sewage attracts rats, flies, and other pests that carry diseases and contribute to unhygienic conditions.
  • Neglected fog fat oil grease treatment escalates the organic sludge build-up, encouraging further pest infestations.

We end up spending more on mosquito repellents and coils, more than on groceries.

  1. Noise Pollution and Operational Disturbances

Some inefficient sewage treatment plants operate with faulty equipment, causing excessive noise due to malfunctioning aerators, pumps, and blowers. Residents may experience:

  • Continuous buzzing or mechanical sounds disrupting sleep.
  • Vibration and rattling noises affecting the structural integrity of nearby buildings.
  • Increased stress and anxiety due to noise pollution.
  1. Decline in Property Value and Quality of Life

An inefficient sewage treatment plant has long-term economic and social implications, including:

  • Decreased property values: Houses near a failing STP are less attractive to buyers and renters.
  • Poor aesthetics: Leaking sewage pipes, overflowing drains, and algae-covered water bodies degrade the visual appeal of the locality.
  • Social stigma: The area gains a negative reputation, discouraging businesses and investments, leading to urban decay.
Understanding the root causes behind the inefficiency of STPs is essential to addressing the problem:
  • Poor Design or Outdated Technology: Many STPs are built with outdated technology or lack design considerations for future population growth and sewage load.
  • Lack of Skilled Manpower: A shortage of trained operators and maintenance staff often results in mismanagement and operational failures.
  • Irregular Maintenance and Monitoring: Preventive maintenance is often ignored, leading to breakdowns and reduced treatment capacity.
  • Inadequate Funding and Budget Cuts: Municipal bodies sometimes lack the funds or political will to upgrade or maintain STPs properly.
  • Overloading: Rapid urbanization can overload existing STPs beyond their capacity, causing untreated sewage to be discharged.
  • Lack of Real-time Monitoring Systems: Without automation and real-time monitoring, inefficiencies go unnoticed until they become severe.
Conclusion

Living near an inefficient STP is not just an inconvenience—it’s a serious environmental and public health issue. While modern wastewater treatment technologies can greatly improve STP efficiency, their implementation requires public awareness, strong governance, and investment in sustainable solutions. Fat oil and grease control and consistent monitoring are vital to long-term success.

Strategies To Reduce FOG Related Challenges
Why Is FOG a Problem in Wastewater Treatment Plants? – An EHS Manager’s Perspective
Introduction

For an Environmental, Health, and Safety (EHS) Manager, managing sewage treatment plants efficiently is critical to ensuring compliance with environmental regulations and maintaining operational efficiency. One persistent challenge in wastewater treatment plants (WWTPs) is the presence of Fats, Oils, and Grease (FOG). Left unchecked, FOG can cause severe operational, environmental, and financial issues.

This blog explores why fats oils and grease in wastewater is a problem in WWTPs and discusses practical solutions to mitigate its impact. For more information on effective fat oil and grease management, contact us.

Understanding FOG and Its Sources

FOG is a collective term for fats, oils, and grease that enter wastewater systems, primarily from industrial, commercial, and residential sources. Key contributors include:

  • Food Processing Plants (dairy, meat, poultry, seafood, bakeries)
  • Restaurants & Commercial Kitchens (cooking oils, animal fats, dairy by-products)
  • Dairy & Beverage Industries (cream, butter, and cheese residues)
  • Households & Residential Areas (cooking waste, soap, and detergents)

While fat oil and grease may seem harmless in small amounts, its accumulation in wastewater treatment plants poses significant challenges.

Why Is FOG a Problem in Wastewater Treatment Plants?
1. Clogging & Blockages in Pipelines

FOG solidifies as it cools, creating thick deposits that reduce pipe capacity and eventually cause blockages. This leads to:

  • Reduced hydraulic efficiency
  • Increased risk of sanitary sewer overflows (SSOs)
  • Expensive pipeline cleaning and maintenance

Learn more about fat oil grease removal systems designed to combat this issue.

2. Disrupts Biological Treatment Processes

WWTPs rely on microbial activity to break down organic matter. However, excessive fats oils and grease:

  • Forms a hydrophobic layer that limits oxygen transfer, affecting aerobic bacteria
  • Inhibits microbial metabolism, leading to incomplete organic degradation
  • Causes biomass washout in activated sludge and biological treatment systems

Explore our detailed article on biological oxygen demand and its impact on fats oils and grease in wastewater treatment.

3. Increases Sludge Generation & Disposal Costs

FOG contributes to excessive sludge buildup, resulting in:

  • Higher sludge disposal costs
  • Increased dewatering and treatment demands
  • Potential for odor issues due to anaerobic degradation

Read about fat oil and grease removal from wastewater techniques that address sludge issues effectively

4. Impacts Effluent Quality & Compliance

Regulatory agencies set strict discharge limits for oil and grease. Excess FOG in effluent can result in:

  • Permit violations and regulatory fines
  • Non-compliance with local environmental discharge standards
  • Increased treatment costs for tertiary filtration and polishing

Stay informed about environmental regulations governing wastewater treatment plants.

5. Damages Equipment & Increases Maintenance Costs

FOG accumulations in pumps, aerators, and diffusers can cause:

  • Pump failures due to grease coating impellers
  • Reduced aeration efficiency, leading to poor oxygen transfer
  • Frequent cleaning & replacements, increasing operational expenses
Solutions for EHS Managers to Control FOG in WWTPs
1. Source Control – Prevent FOG from Entering Wastewater
  • Implement grease trap installation and maintenance programs for industries and food establishments.
  • Educate businesses and residents on FOG disposal best practices (e.g., avoid pouring grease down the drain).
  • Enforce pre-treatment regulations requiring businesses to control fat oil and grease discharge.
2. Biological FOG Degradation Using Biocultures
  • Introduce FOG-degrading microbial solutions/biocultures to enhance biodegradation in treatment units.
  • Use customized biocultures that break down fatty acids into biodegradable components.
3. Implementing FOG Interceptors & Skimming Systems
  • Install FOG interceptors in sewer lines to trap grease before it reaches treatment plants.
  • Use mechanical skimmers in equalization tanks and aeration basins to remove floating fats oils and grease.
4. Chemical & Enzymatic Treatment
  • Apply degreasers and surfactants to break down grease in lift stations and pipelines.
  • Use enzyme-based solutions to facilitate fat oil and grease removal from wastewater without harming microbial balance.
5. Optimize Operational Strategies
  • Maintain optimum temperature in digesters to ensure FOG breakdown.
  • Regularly clean aeration tanks and pipelines to prevent grease accumulation.
  • Adjust hydraulic retention time (HRT) to accommodate fat oil and grease management.
Conclusion

For an EHS Manager, tackling fats oils and grease is essential for maintaining compliance, operational efficiency, and cost-effectiveness in wastewater treatment plants. Proactive strategies—such as source control, bioculture addition, interceptor installations, and optimized operational practices—can significantly reduce FOG-related challenges.

By implementing these measures, WWTPs can improve treatment efficiency, extend equipment life, and avoid costly regulatory fines. A well-managed fat oil grease removal system ensures a sustainable and environmentally responsible wastewater treatment system.

STP – Odour Control, Odour Reduction, Cheap BIoproducts, Powder Bioproduct, Liquid Bioproduct, Bio Culture For Sewage Treatment Plant

Several factors can undermine the effectiveness and efficiency of a sewage treatment plant. Factors such as composition (high levels of organic matter, nutrients or toxicity) of sewage wastes, higher temperatures that can reinforce microbial activity that breaks down organic sludge, hydraulic retention time, adequate oxygen supply to support microbial growth, and appropriate alkalinity of wastewater are among the most common ones.

It naturally becomes vital that any microbial formulation added to any STP can work through these variables. Team One Biotech’s “T1B STP” is a consortium of resilient & robust bacteria that facilitate the biodegradation of sewage wastes & organic pollutants by converting them into carbon dioxide, water and smaller biodegradable compounds.

T1B STP controls the formation of excessive organic sludge by rapidly degrading it. It also improves the settling rate of activated sludge for filtration and settling processes.

Longer retention time although allows for a more thorough treatment, it also increases the risk of odours and the growth of harmful organisms. T1B STP specializes in controlling filamentous bacterial growth in sewage management and also eliminates odours.

With its many beneficial properties like the high potency of reducing BOD, COD and ammonia, improving conditions for better floc formations, and controlling sludge bulking and excess foaming T1B STP applications are many. T1B STP microbial formulation can be used in any sewage treatment plant, sewer lines, STP pumping stations, municipal waste disposals and even for compact plants in housing complexes, hospitals etc.
