Municipal Corporation of Greater Mumbai (MCGM)
Covering Mumbai City Sewerage Operations, for 54 Pumping Stations & 7 Treatment
Plants
The Customer
MCGM is a leader in Municipal Corporation managing a mage-city, with one of the
highest population densities in the world, and its extensive experience in handling complex
urban issues makes it a model for Municipalities in India & Beyond.
Datamatrix was awarded the
single largest Audit assignment in India at the time. The project covered the Greater
Mumbai City divided into four zones covering City-1, City-II, Eastern & Western Suburbs.
The Challenge
The drastic variation in sewage flow during the day and significant seasonal variation in the flow rate during monsoon, due to the rainwater entering the sewer network, posed significant challenges for managing the sewage systems. The prior pilot project successfully executed at MCGM - Bhandup Water Works, successfully executing Datamatrix Virtual Pump Station for their Drinking water systems, gives an edge in the competition, with a proven ability to handle this challenge, with its unique technology capabilities.
The Solution
Datamatrix has captured the critical operational data of each pump station and treatment plant for a minimum period of 24 hours to several weeks depending on the criticality of the stations. Datamatrix has further carried out detailed testing of each pump capturing its characteristics operating as at site. It helped to simulate the head, flow and pumping efficiencies against various operating scenarios of the day using the Datamatrix Technology Platform and identify the stress points, overflow and sewerage stagnation threats.
Datamatrix has made specific Reports for Each Pump Station, and made
recommendations for
1. Preferred Machine Sequence for Pumping Operations
2. Recommended Water Levels during the time of day, & Seasons
3. Operational Strategies for Each Station Based on Specific Challenges
Datamatrix has devised an Energy Management and Asset Renewal Policy, and
continuous improvement plan over the years which includes:
1. Devised a Method to compare the Performance of each pump set, despite their wide variation capacity and lift, devising a universal comparison of specific energy per unit lift to compare each category and range of pumps, for asset renewal.
2. Devised Detailed Energy Management Plan with Continuous Improvement & Training Program, with Monthly Reporting of Key Performance Indicators across the Stations.
3. Utility wide Strategic Asset Renewal Plan against each Critical Asset (Motor-Pump Set) under each category and range, based on their Performance and Running Hrs, and Perceived Risk and Payback, with flexibility for yearly decision making.
4. Taking up Tarif Restructuring issues with the Energy Regulatory Commission, over the Tariff Disparities between 4 Utilities supplying Power across Mumbai City, for fair and justifiable Tariffs.
Outcomes of the Project
The Audit Report identified & Implemented the following opportunities
1. Operational Optimisation = 5.3% (50% Implemented in first year)
2. Energy Cost reduction by Power Factor Improvement = 5.2% (Implemented in First Year)
3. Immediate Replacement = 3.3% (Implemented in First Year)
4. Strategic Asset Renewal. = 4% (To be Implemented in the next 2 years)
First year implementation under our supervision including tendering and finalisation
