Portable STP for Educational Institutions – Cost & Compliance Benefits Case Study on Smarter Wastewater Management

Introduction: A Problem No One Talks About Until It Becomes One 

 In educational institutions, conversations usually revolve around academics, infrastructure, student safety, and growth. Rarely does wastewater management make it to the priority list—until a notice arrives from authorities, costs spiral unexpectedly, or water shortages begin affecting daily operations. This was the reality for many schools, colleges, and training campuses that approached us. They weren’t looking for innovation. They were looking for relief. 

Relief from rising tanker costs. Relief from regulatory pressure. Ease of burdening, space-intensive sewage treatment systems. 

That’s where Portable STPs (Sewage Treatment Plants) came in. 

The Common Challenge Across Campuses 

Educational institutions face a unique set of constraints: 

1. Limited Space, Expanding Needs 

Most campuses were designed years ago , long before as compared to the school going student strength we have right now . The majority of the campuses were made many years ago when compared to the school going student strength that we presently possess. Installation of a traditional underground STP implied: Intensive civil activities, Playgrounds or parking lots loss, Prolonged construction periods.  In the case of a running school or college, this was not a sacrifice that could be made.   

2. Increasing Compliance Pressure 

India's Pollution Control Boards are enforcing stricter regulations regarding Water reuse, sewage discharge, and environmental compliance 

Many establishments relied on external disposal or septic tanks, which Penalties, repeated inspections, invited notices, and unsuccessful compliance checks It caused management teams to feel uneasy. Pollution Control Boards across India are enforcing stricter regulations regarding sewage discharge, water reuse, and environmental compliance. Most of the establishments used external disposal or septic tanks that: The management teams were scared because they were unable to pass the compliance inspection, received notices, fines, and repeated inspections. 

Pollution Control Boards across India are tightening regulations around:

• Sewage discharge standards

• Mandatory water reuse

• Overall environmental compliance

What was once overlooked is now actively monitored and enforced.

Most educational institutions continued to rely on septic tanks or external sewage disposal systems- solutions that were no longer sufficient. As a result, many campuses faced:

• Failure during compliance inspections

• Official notices, fines, and repeated follow-ups

• Uncertainty and constant anxiety among management teams

Compliance shifted from being a formality to a serious operational and reputational risk.

For institutions, the message became clear:Adapt quickly- or face escalating scrutiny.

3. Rising Water & Tanker Costs 

Freshwater consumption was increasing every year: - Toilets - Gardening - Floor washing 

With borewells depleting and municipal supply inconsistent, tanker water became the default backup- at a growing cost. Freshwater consumption across campuses was increasing year after year, driven by daily essentials such as:

• Toilet flushing across hostels, classrooms, and staff areas

• Gardening and landscape maintenance

• Floor washing and general housekeeping

What once seemed manageable slowly became a strain.

Borewells began showing signs of depletion, while municipal water supply remained inconsistent and unpredictable. During peak months, availability dropped just when demand was highest.

As a result, tanker water shifted from being an occasional backup to a daily necessity.

This came at a cost.

• Monthly water expenses kept rising

• Budgets became harder to predict

• Dependency on external suppliers increased

• Long-term water security became uncertain

  
  

  “We were spending more every year just to maintain the same level of operations.”

For institutions, the challenge was no longer just about water availability- it was about financial sustainability and future readiness.

The Turning Point: Looking for a Practical Solution 

What institutions truly needed was not a complex treatment plant - but a plug-and-play solution. 

Something that: - Could be installed quickly - Required minimal space - Met pollution control norms - Allowed treated water reuse - Didn’t burden staff with complex operations 

That led them to Portable STPs. 

The Solution: Portable STP Designed for Campuses 

Portable STPs are prefabricated, above-ground sewage treatment systems that can be deployed without major civil construction. 

For educational institutions, this changed everything. 

Key Features That Made the Difference: 

• Compact footprint suitable for tight campuses 

• Modular design that can scale with student strength 

• Quick installation often within weeks, not months 

• Fully compliant treated water output 

• Low operational complexity for on-ground staff 

Instead of building an STP, institutions simply installed one. 

Implementation: Simple, Fast, and Non-Disruptive 

The process followed a clear, stress-free path: 

1. Site assessment to understand sewage load 

2. Capacity planning based on current and future student strength 

3. Factory-fabricated STP delivery 

4. On-site installation & commissioning 

5. Basic staff training for operations 

Classes continued. Campuses stayed functional. No digging. No chaos. 

The Cost Advantage: Where the Real Relief Came From 

1. Lower Capital Cost 

Compared to conventional civil STPs: - No excavation - No RCC tanks - No long construction timelines 

This resulted in significant upfront cost savings. 

2. Reduced Water Bills 

Treated water was reused for: - Toilet flushing - Gardening - Floor cleaning 

Freshwater demand dropped sharply. 

“We stopped depending on tanker water for half our daily needs.” 

3. Predictable Operating Costs 

Portable STPs are designed for: - Low energy consumption - Minimal chemical usage - Easy maintenance 

This made budgeting easier for finance and administration teams. 

Compliance Benefits: Peace of Mind for Management 

One of the biggest wins wasn’t financialit was psychological. 

With a Portable STP in place: - Treated water  - Inspection readiness improved - Documentation became simpler - Notices and penalties reduced 

“For the first time, compliance wasn’t something we feared.” 

The Human Impact: Beyond Infrastructure 

For Students 

• Cleaner, better-maintained washrooms 

• Greener campuses with regular landscaping 

• Exposure to sustainable practices in real life 

For Staff 

• Easier operations 

• Fewer emergencies related to sewage overflow 

• Clear processes and accountability 

For Management 

• Long-term cost control 

• Compliance confidence 

• Alignment with ESG and sustainability goals 

This case study highlights a simple truth: 

Educational institutions don’t need complex infrastructure. They need reliable, compliant, and scalable solutions. 

Portable STPs bridge the gap between regulation and reality. 

How Ekam Portable STP Solves the Water & Cost Challenge

Ekam’s Portable STP helps educational institutions break the cycle of rising freshwater consumption and tanker dependency by turning wastewater into a reliable, reusable resource.

Instead of letting sewage become a disposal problem, Ekam’s system treats it on-site and makes it usable again.

1. Reduces Freshwater Demand at the Source

Treated water from Ekam’s Portable STP is safely reused for:

• Toilet flushing

• Gardening and landscaping

• Floor washing and housekeeping

This significantly cuts the demand for fresh groundwater and municipal supply often by 30–50% or more, depending on campus size and usage.

2. Cuts Tanker Dependency & Operating Costs

With a steady supply of treated water available on campus:

• Tanker water becomes an emergency backup, not a routine expense

• Monthly water bills reduce and stabilize

• Budget planning becomes predictable

“Once treated water was reused, tanker costs dropped almost immediately.”
