The Challenge: Safe Drinking Water for Construction Site Workers

NCC Ltd, one of India's leading construction companies, required a reliable water purification system for their BMRCL Phase 2B metro construction site in Kannur. The challenges included:

  • Providing safe drinking water for 100+ construction workers daily

  • Meeting BMRCL's health and safety compliance requirements

  • Dusty construction environment requiring robust filtration

  • Variable raw water quality at construction sites

  • Need for high-capacity continuous operation

  • Automatic system to reduce manual intervention

  • Compliance with government drinking water standards

  • Minimal maintenance downtime

  • Long-term reliability in harsh site conditions

The project required a turnkey solution including installation, commissioning, and long-term maintenance support.
