Britannia Industries Limited
The Challenge
Failed ETP Infrastructure and Compliance Risk
Britannia Industries Limited is one of India's leading food manufacturing companies, producing a wide range of bakery products including biscuits, bread, cakes, and dairy items across multiple manufacturing facilities nationwide. As a major FMCG player in the confectionery and baked goods sector, Britannia generates significant process wastewater from production line cleaning, ingredient processing, and utility operations.
With increasingly stringent environmental regulations and corporate sustainability commitments, the company required a robust Effluent Treatment Plant (ETP) solution to ensure consistent regulatory compliance, reduce water consumption, and minimize their manufacturing water footprint while supporting production expansion plans.
Key Issues:
- !Previous engineering partner delivered an undersized ETP system that failed within 2 years
- !Company faced ₹2 crore capex impairment risk and potential compliance issues
- !Existing system couldn't meet operational demands or regulatory requirements
The Solution
Complete ETP Redesign Engineered for Long-Term Performance
Spans Envirotech redesigned the complete treatment train and operating regime from the ground up. Rather than patching the failing system, we implemented a scalable solution engineered for future growth and lifecycle performance.
Our approach focused on long-term total cost of ownership rather than just initial capital expenditure — selecting robust equipment, optimising process design for the actual wastewater characteristics, and building in operational simplicity to reduce the day-to-day burden on Britannia's maintenance team.

Implementation Timeline:
Phase 1: Assessment & Redesign
Conducted a full audit of the failed system, identified undersizing and design flaws, and developed a comprehensive redesign plan addressing real-world wastewater characteristics and future growth requirements.
Phase 2: Infrastructure Rebuild
Salvaged viable components from the existing system and implemented a properly-sized, robust treatment solution — avoiding the cost of starting from scratch while delivering a system built for long-term reliability.
Phase 3: Commissioning & Optimisation
Commissioned automated controls and optimised operational parameters. Reduced chemical consumption, energy usage, and manual intervention points, delivering a simplified O&M regime for Britannia's plant operators.
The Results
Capital Protected, Compliance Assured, Operations Simplified
₹2 Cr
Capital Loss Avoided
Prevented total write-off of failed infrastructure through intelligent redesign and component salvage

“Spans Envirotech saved us from a ₹2 crore capital disaster and delivered a wastewater treatment solution that actually works. Their engineering approach—designing for real-world conditions and total lifecycle cost rather than just initial capex—has given us sustained compliance, lower operating costs, and complete peace of mind. This is what true engineering partnership looks like.”
