Only 104 of 594 Sewerage Projects Completed: Why India Urgently Needs More Sewage Treatment Plants

India is facing a wastewater challenge that deserves much more attention.

A recent update on AMRUT 2.0 sewerage and septage-management projects has highlighted a major gap in the pace of wastewater infrastructure development. Out of 594 approved sewerage and septage-management projects, only 104 projects — around 17.51% — have been completed, while 398 projects remain under implementation. The approved projects have a combined value of approximately ₹68,309 crore.

This is not simply a government infrastructure statistic.

It is a warning about India's growing wastewater challenge.

As cities expand, populations increase and new apartments, commercial buildings, hospitals, hotels, schools, colleges and industries are developed, sewage generation also increases.

Every day, millions of litres of wastewater are produced.

The question is:

Are we building wastewater treatment infrastructure fast enough to manage it?

The latest figures suggest that much more needs to be done.

And this is why Sewage Treatment Plants (STPs) are becoming increasingly important for India's cities, communities, institutions and businesses.

What Do the 104 of 594 Projects Mean?

The numbers are significant.

Under AMRUT 2.0, 594 sewerage and septage-management projects have been approved, but only 104 have been completed according to the latest parliamentary-panel reporting. That means the vast majority of these approved projects are still at various stages of implementation.

The same report states that 398 projects, or about 67%, remain under implementation.

Another 38 projects were reported to still be at the tender stage.

The Parliamentary Standing Committee has therefore called for faster implementation and stronger monitoring, particularly because delays can postpone the creation of sewage-treatment capacity, sewerage connectivity and septage-management infrastructure.

For India's rapidly growing cities, this is an important issue.

Wastewater generation does not stop while infrastructure projects are waiting to be completed.

Buildings continue to generate sewage.

People continue to use water.

Industries continue their operations.

Hotels continue serving guests.

Hospitals continue providing healthcare.

Schools and colleges continue functioning.

Every activity creates wastewater.

That wastewater needs a proper destination.

Why India Needs More Sewage Treatment Plants

The basic water cycle inside a city is straightforward.

Water enters a home, apartment, hotel, office, hospital, school, commercial building or industrial facility.

People use that water.

After use, a significant portion becomes wastewater.

That wastewater must then be:

Collected → Treated → Safely Discharged or Reused

When wastewater infrastructure is insufficient, the pressure moves elsewhere.

It can affect drainage systems, water bodies, groundwater and the surrounding environment.

This is why sewage treatment capacity needs to grow alongside urban development.

Urban Growth Means More Wastewater

Consider a city that is adding thousands of new homes.

Every new household consumes water.

Every household produces wastewater.

Now multiply that by:

• Apartment communities

• Gated communities

• Villas

• Hotels

• Hospitals

• Schools

• Colleges

• IT parks

• Shopping centres

• Offices

• Factories

• Industrial parks

The volume becomes enormous.

Therefore, sewage treatment cannot be treated as a secondary infrastructure requirement.

It must be part of the core planning of a growing city.

What Happens When Wastewater Treatment Capacity Is Delayed?

When sewage-treatment infrastructure is delayed, the problem is not simply that a project remains unfinished.

The wider wastewater-management system can also face pressure.

1. Greater Pressure on Water Bodies

Inadequately treated wastewater can contribute to pollution when it enters rivers, lakes, canals or other receiving environments.

2. Greater Pressure on Freshwater Resources

When treated wastewater is not reused, fresh water may continue to be used for applications where potable-quality water may not always be necessary.

3. Public Health Concerns

Sewage can contain microorganisms and other contaminants. Proper wastewater treatment is therefore an important part of environmental and public-health protection.

4. Urban Drainage Problems

Poorly managed wastewater can contribute to unpleasant conditions, odour and local drainage challenges.

5. Lost Opportunity for Water Reuse

Wastewater is not necessarily useless water.

With suitable treatment, it can potentially become a source of water for appropriate non-potable applications.

Wastewater Should Not Be Treated as "Waste"

The word wastewater can create the wrong impression.

It is water that has already been used.

That does not mean it has no value.

Once appropriately treated, wastewater can potentially be reused for applications such as:

• Landscaping

• Gardening

• Toilet flushing

• Certain cleaning applications

• Construction-related uses

• Selected industrial applications

• Other approved non-potable purposes

The exact reuse application depends on treated-water quality, project requirements and applicable regulations.

This creates a much more sustainable approach:

Traditional Water Cycle

Freshwater → Use → Wastewater → Disposal

Circular Water Approach

Freshwater → Use → Wastewater → Treatment → Reuse

The second approach can help reduce freshwater demand for suitable non-potable applications.

That is why modern sewage treatment should not be viewed only as pollution control.

It should also be viewed as part of water conservation and resource management.

What Is a Sewage Treatment Plant?

A Sewage Treatment Plant, commonly called an STP, is a system designed to treat domestic sewage and wastewater.

Its purpose is to reduce pollutants and contaminants so the treated water can meet the required quality for its intended discharge or reuse.

An STP may include several treatment stages depending on the technology and project requirements.

These can include:

1. Screening

2. Collection and equalisation

3. Biological treatment

4. Settling

5. Filtration

6. Disinfection

7. Sludge management

8. Treated-water reuse or discharge

The exact process should be selected according to:

• Wastewater characteristics

• Daily flow

• Peak flow

• Required treatment quality

• Site conditions

• Intended reuse

• Applicable environmental requirements

• Future expansion requirements

There is no single STP design that is automatically suitable for every project.

Proper engineering matters.

Why Biological Sewage Treatment Is Important

Biological treatment is widely used for domestic sewage because microorganisms can naturally break down biodegradable organic matter.

In a biological treatment process, microorganisms consume organic pollutants in wastewater under controlled conditions.

This can help reduce the organic load of sewage before further treatment and disinfection.

Biological treatment can be incorporated into different STP configurations depending on the project's capacity, wastewater characteristics, land availability and required treated-water quality.

For residential, commercial and institutional applications, selecting the correct biological process is an important engineering decision.

Why Apartments and Gated Communities Need Better STP Planning

India's cities are seeing continued development of large residential communities.

A single apartment project can have:

• Hundreds of residents

• Multiple buildings

• Clubhouses

• Swimming pools

• Restaurants

• Common toilets

• Landscaped areas

• Parking facilities

• Maintenance facilities

All of these contribute to water consumption and wastewater generation.

Therefore, the STP should be considered during the earliest stages of project planning.

Apartment developers and associations should ask:

How much sewage will we generate today?

How much could we generate in the future?

Where will the treated water be used?

Is there sufficient space for the treatment system?

Can the STP be installed underground?

How will the system be operated and maintained?

These questions can make a significant difference to long-term wastewater management.

Hospitals Cannot Ignore Wastewater Management

Hospitals are another important category.

Healthcare facilities generate wastewater from:

• Patient rooms

• Toilets

• Bathrooms

• Kitchens

• Laundry

• Staff facilities

• Laboratories

• Other hospital operations

Because wastewater characteristics can vary significantly, hospitals need appropriate wastewater-management planning based on their actual activities.

Treatment, disinfection, monitoring, sludge handling and applicable regulatory requirements all need to be considered.

A hospital's wastewater system should not be selected simply because it is the cheapest option.

It should be selected based on performance, suitability and long-term reliability.

Hotels and Resorts Are Major Water Users

Hotels use water throughout the day.

Guests consume water.

Kitchens consume water.

Laundry consumes water.

Housekeeping consumes water.

Landscaping consumes water.

All of this creates wastewater.

A properly designed STP can help hospitality businesses manage their sewage responsibly.

Where treated-water quality and local requirements permit, treated wastewater can potentially be reused for landscaping, flushing and other suitable non-potable purposes.

This can support a hotel's sustainability goals while reducing freshwater demand.

Schools and Colleges Can Build Sustainable Campuses

Educational institutions have a special opportunity to demonstrate responsible water management.

Schools and colleges can use appropriate sewage treatment systems to manage wastewater generated by:

• Students

• Teachers

• Staff

• Hostels

• Canteens

• Toilets

• Campus facilities

A campus can potentially treat wastewater and reuse suitable treated water for landscaping or other permitted applications.

More importantly, students can see sustainability in action.

The concept is simple:

Use water → Treat wastewater → Reuse water

That is an important lesson for the next generation.

Commercial Buildings Need Wastewater Planning Too

Shopping centres, offices, IT parks, business centres and other commercial buildings can generate significant quantities of sewage.

Their wastewater comes from:

• Toilets

• Cafeterias

• Kitchens

• Housekeeping

• Staff areas

• Visitors

• Other commercial activities

A suitable STP can help these facilities manage sewage while supporting water conservation through appropriate reuse.

The treatment system should be designed according to actual wastewater generation and project requirements.

Industrial Facilities Have an Additional Responsibility

Industrial wastewater requires particular attention because not all wastewater is the same.

A factory may generate:

Domestic Sewage

Wastewater from toilets, bathrooms, kitchens and staff facilities.

Industrial Effluent

Wastewater generated by manufacturing or industrial processes.

These two streams may require different treatment approaches.

Domestic sewage may be treated through an STP.

Industrial effluent may require an Effluent Treatment Plant (ETP) or specialised treatment process depending on the industry and contaminants involved.

This distinction is extremely important.

A wastewater-treatment system must be based on the actual wastewater being generated.

Why Underground RCC STPs Can Be a Smart Option

Land availability is a major challenge in urban areas.

A project may need space for:

• Buildings

• Parking

• Roads

• Gardens

• Play areas

• Utility systems

• Fire-safety infrastructure

• Wastewater treatment

This is where an underground STP can offer an important advantage for suitable projects.

An underground RCC sewage treatment plant can place the primary treatment tanks below ground level, with appropriate access points and manholes provided for inspection and maintenance.

This can help preserve valuable surface space.

Instead of having large treatment tanks occupying the visible area of a property, the project can potentially use the surface for landscaping, parking or other planned purposes.

However, underground RCC construction must be properly engineered.

Important considerations include:

• Soil conditions

• Groundwater levels

• RCC structural design

• Waterproofing

• Buoyancy

• Ventilation

• Access

• Maintenance requirements

• Tank loading

• Site-specific engineering conditions

A good underground STP is not simply a tank placed below the ground.

It is an engineered wastewater-treatment system.

STP Capacity Must Match Wastewater Generation

One of the most important decisions when planning an STP is capacity.

An undersized STP can face operational challenges when wastewater generation exceeds its design capacity.

An unnecessarily oversized STP can also create inefficiencies.

Therefore, the capacity should be determined after assessing:

• Population

• Occupancy

• Water consumption

• Sewage generation

• Peak flow

• Future expansion

• Seasonal variations

• Commercial or industrial activities

The correct capacity is not simply a number selected from a standard table.

It should be based on the project's actual requirements.

Why Treated-Water Reuse Should Be Planned From Day One

A major mistake is to install an STP first and decide what to do with the treated water later.

A better approach is to ask the reuse question before designing the plant:

Where will the treated water go?

Possible applications can include:

Landscaping

Treated water may be suitable for landscaping when the required quality is achieved and reuse is permitted.

Toilet Flushing

Suitable recycled water can potentially reduce freshwater consumption for flushing.

Cleaning

Certain non-potable cleaning activities may be suitable for treated water depending on quality requirements.

Industrial Reuse

Some industrial processes may be able to use treated wastewater after meeting appropriate quality standards.

Other Non-Potable Applications

Project-specific applications can be considered based on technical feasibility and applicable regulations.

The better the reuse plan, the more valuable the wastewater-treatment system can become.

The Real Challenge Is Not Just Building STPs

India needs more sewage treatment plants.

But building an STP alone is not enough.

A treatment plant must also:

• Receive the expected wastewater flow

• Operate correctly

• Be maintained properly

• Achieve the required treatment performance

• Be monitored

• Handle sludge appropriately

• Have reliable equipment

• Have trained personnel where required

• Provide safe treated-water reuse or compliant discharge

An STP that exists physically but is poorly operated cannot solve the wastewater problem effectively.

Therefore, construction + commissioning + operation + maintenance + monitoring must all be considered together.

Why Faster Wastewater Projects Matter for India

The latest AMRUT 2.0 figures demonstrate the importance of timely implementation.

The Parliamentary Standing Committee has specifically raised concerns about the pace of sewerage and septage-management projects and recommended stronger timelines and milestone-based monitoring.

This matters because cities cannot pause wastewater generation while infrastructure is being developed.

Population growth continues.

Urbanisation continues.

Construction continues.

Commercial activity continues.

Industrial activity continues.

Wastewater continues to flow.

Therefore, wastewater infrastructure must be planned and delivered proactively.

India Needs a New Wastewater Mindset

The wastewater conversation needs to change.

For decades, many people have thought about sewage in one simple way:

"Get it out of my building."

That is not enough anymore.

The better question is:

"Where does it go, how is it treated, and can it be safely reused?"

That is the mindset India needs.

Wastewater management should become part of responsible urban development.

What Builders and Developers Should Do

Developers planning new projects should consider wastewater treatment before construction begins.

Step 1: Calculate Wastewater

Estimate expected sewage generation based on population and water consumption.

Step 2: Plan for Future Growth

Do not design only for today's population if the project will expand.

Step 3: Select the Appropriate Technology

Technology should be selected based on wastewater characteristics, required output quality, land availability and project objectives.

Step 4: Consider Underground Installation

Where appropriate, underground RCC STP construction can help optimise available land.

Step 5: Plan Treated-Water Reuse

Decide where treated water will be used before finalising the treatment system.

Step 6: Plan Access and Maintenance

Even underground systems require suitable access for inspection, maintenance and servicing.

Step 7: Consider Compliance

The project should account for applicable environmental and local requirements.

Step 8: Plan Long-Term Operation

The STP should be practical to operate and maintain throughout its service life.

What Individuals Can Do to Support Better Wastewater Management

Wastewater treatment is not only the responsibility of governments and STP manufacturers.

Individuals can also help.

Simple actions include:

• Do not throw plastic or solid waste into toilets.

• Avoid putting oils and harmful chemicals into drains.

• Reduce unnecessary water wastage.

• Report sewage leaks or overflows.

• Support proper wastewater treatment in residential communities.

• Encourage safe treated-water reuse.

• Learn where wastewater from your property is going.

Small actions become powerful when millions of people participate.

The Future of India's Water Management Is Reuse

Freshwater is too valuable to use once and simply discard as wastewater.

The future should increasingly involve:

Water Conservation

Wastewater Treatment

Water Recycling

Safe Reuse

Resource Recovery

This is especially important in rapidly growing cities.

A building that treats and reuses suitable wastewater can reduce its dependence on freshwater for some non-potable applications.

At a city level, the combined effect could be enormous.

104 Completed Projects Are Not Enough

The latest figure of 104 completed projects out of 594 approved projects should not simply be viewed as a statistic.

It should encourage a broader discussion about India's wastewater future.

How quickly can treatment infrastructure be created?

How effectively will it be operated?

How much treated water can be reused?

How can cities reduce freshwater demand?

How can sewerage systems keep pace with urban expansion?

And how can individual buildings contribute to the solution?

These questions matter because India's water future depends not only on how much water we can obtain, but also on how responsibly we use and reuse it.

Sewage Treatment Is an Investment in India's Future

A sewage treatment plant should not be considered merely another infrastructure expense.

It can be an investment in:

• Cleaner water bodies

• Better sanitation

• Water conservation

• Sustainable buildings

• Responsible urban development

• Environmental protection

• Future water security

Every properly treated litre of wastewater represents an opportunity to reduce pollution and, where appropriate, recover water for beneficial reuse.

Why Businesses Should Act Now

Businesses that generate significant wastewater should not wait until wastewater-management problems become urgent.

Planning early provides an opportunity to consider:

• Correct STP capacity

• Suitable technology

• Underground RCC construction

• Automation

• Water recycling

• Treated-water reuse

• Long-term maintenance

• Site constraints

• Future expansion

A well-planned wastewater system can become part of a company's wider sustainability strategy.

India's Wastewater Problem Requires Everyone's Participation

Government projects are essential.

Large municipal STPs are essential.

Sewer networks are essential.

But private developments also have a role.

Apartments need STPs.

Hospitals need appropriate wastewater systems.

Hotels need wastewater management.

Schools and colleges need treatment systems.

Commercial buildings need responsible wastewater infrastructure.

Industries need suitable STPs and, where applicable, ETPs.

Every project that treats its wastewater responsibly contributes to the larger solution.

Conclusion: India Cannot Wait to Solve Its Wastewater Problem

The latest AMRUT 2.0 project figures have brought an important issue into focus.

With only 104 of 594 approved sewerage and septage-management projects completed, India's wastewater infrastructure still has significant ground to cover. The Parliamentary Standing Committee has called for faster implementation because delays can postpone the creation of treatment capacity and sewerage infrastructure.

But India's wastewater challenge is much larger than government projects.

It affects every growing city.

Every apartment.

Every hotel.

Every hospital.

Every school.

Every commercial building.

Every industrial facility.

And ultimately, every person who uses water.

The solution is not simply to use more freshwater.

The solution is to use water responsibly, treat wastewater properly and safely reuse treated water wherever technically feasible and permitted.

India needs more sewage treatment plants.

But it also needs better planning, smarter treatment, reliable operation, effective maintenance and greater water reuse.

The future of wastewater management is not:

Use → Waste → Discharge

It should increasingly become:

Use → Treat → Reuse → Conserve

That is how wastewater can become part of the solution rather than remaining part of the problem.
