The Background
A major commercial complex in Hyderabad was operating a sewage treatment plant (STP) with a 600 KLD capacity, intended to recycle wastewater for non-potable reuse such as flushing and gardening.
Over time, the plant developed severe inefficiencies, poor treatment quality, high costs, and untreated discharges, leading to regulatory non-compliance and environmental concerns. Odour issues created discomfort for occupants, and untreated sewage flowing into nearby water bodies raised ecological risks.
To address these challenges, Megaliter Varunaa stepped in with its investment-backed O&M model. By funding the upgrade and taking full ownership of long-term operations, we delivered consistent compliance, reduced freshwater dependency, and stress-free plant management.
The Challenges of the Existing STP
- Technology Failure: The old RMBR system underperformed, releasing inadequately treated water and driving up costs.
- Underutilization: The plant functioned at just 30% of its capacity, with outdated equipment at the end of its lifecycle.
- High Costs: Excessive energy consumption, chemical use, and tanker purchases inflated operating expenses.
- Lack of Skilled Resources: The client had no dedicated expertise for daily operations, leading to mismanagement.
- Odour & Environmental Concerns: Persistent foul odour impacted user experience, while untreated discharges threatened nearby ecosystems.
The Megaliter Model
Instead of requiring a large upfront capital investment, Megaliter funded the entire upgrade and signed a long-term O&M contract to ensure stress-free management.
Re-engineering and Upgradation
- Replaced the outdated RMBR system with an advanced Membrane Bioreactor (MBR), capable of handling the full 600 KLD load.
- Installed high-efficiency pumps, aerators, control panels, and membrane filters to eliminate odour and ensure reliable water quality.
Comprehensive O&M
- End-to-End Responsibility: Megaliter manages operations, maintenance, repairs, and manpower under one umbrella.
- Efficiency Gains: Optimised pumping schedules and energy-efficient equipment reduced treatment costs.
- Real-Time Transparency: Continuous monitoring and reporting ensure compliance and accountability.
