2024: Q1 Water Analyst, Muscat Bay
Q1 2024 Water Analysis for Muscat Bay
Water Metering Levels at Muscat Bay
- Main BULK Watermeter (L1): Measures the total water entering Muscat Bay.
- Sub BULK Watermeter (L2): Measures water distribution to different zones. Each sub-bulk meter measures the combined usage of all individual meters within its respective zone.
- Individual Meters (L3): Measure consumption at the residential or property level, located inside the zones.
Metering Level Relationships
- The total water measured by L1 should equal the sum of all L2 readings.
- The total water measured by each L2 should equal the sum of all L3 readings within that zone.
- The total water measured by L1 should also equal the sum of all L3 readings across all zones.
Water Consumption Differences and Implications
- The difference between L1 and L2 indicates water loss or leaks in Muscat Bay's common areas.
- The difference between L2 and L3 indicates water loss or leaks within the zones.
- Total monthly water loss in Muscat Bay is calculated as (L1 - L2) + (L2 - L3)
Executive Summary
This report provides a comprehensive analysis of water consumption and non-revenue water (NRW) for Muscat Bay during Q1 2024. The focus is on identifying consumption patterns, discrepancies, and areas with significant water losses. The analysis reveals significant water losses and discrepancies between the different levels of water meter readings. Addressing these issues through improved monitoring, regular maintenance, and community engagement will enhance the efficiency of Muscat Bay's water distribution system and reduce non-revenue water

Monthly Total Loss
4. Key Insights and Trends
Discrepancies and Losses
Observations:
- Significant Water Loss: Consistent and significant water losses between Main BULK (L1) and Sub BULK (L2) meters suggest potential leaks or inefficiencies in the common areas.
- Highest Water Loss: The highest recorded water loss occurred in April 2024, amounting to 6,312 cubic meters.
- Overall Inefficiencies: Significant water loss between main bulk, sub-bulk, and individual meters indicates potential inefficiencies or issues within the entire water distribution system.
- High Loss Zones: Zones 05 and 03(B) show the highest levels of water loss, necessitating immediate attention for potential leaks or meter inaccuracies.
- Stable Zones: Minimal loss in some zones indicates efficient water distribution and accurate metering.
Causes of Water Loss
- Leakage: Potential leaks in the water distribution system, especially in high-loss zones. Recent records indicate several leaks in Zone 05 not attended by COMO, which were later rectified by the Kalhat team. This recurrence suggests poor workmanship by COMO.
- Meter Inaccuracies: Discrepancies between sub-bulk and individual meter readings suggest possible meter inaccuracies.
- Seasonal Variability: Seasonal changes impacting water consumption patterns.
