Explanation of Water Metering Levels at Muscat Bay
Levels of Water Metering at Muscat Bay
L1: Main BULK Watermeter
Measures the total water entering Muscat Bay at the beginning of Muscat Bay.
L2: Sub BULK Watermeter
Measures water distribution to different zones. Each Sub BULK Watermeter is located at the entrance of each zone and measures the combined usage of all the individual/end-user water meters (L3) within that particular zone.
L3: Individual Meters (end-user Watermeter)
Measures consumption at the residential or property level, located inside the zones.
Relationships Between Metering Levels
L1 = Total of L2
The total amount measured by the Main BULK Watermeter should equal the sum of all Sub BULK Watermeter readings.
L2 = Total of L3
The total amount measured by each Sub BULK Watermeter should equal the sum of all individual meters (L3) within that zone.
L1 = Total of L3
The total amount measured by the Main BULK Watermeter should also equal the sum of all individual meters (L3) across all zones.
Water Consumption Differences and Their Implications
A) Difference Between L1 and L2
Indicates water loss or leaks in the common areas of Muscat Bay.
B) Difference Between L2 and L3
Indicates water loss or leaks inside the zones of Muscat Bay.
Total Water Loss in Muscat Bay on a Monthly Basis
Total water loss = A (L1 - L2) + B (L2 - L3)

2. Overview of Water Metering at Muscat Bay
2.1 Levels of Water Metering
L1: Main BULK Watermeter
Measures total water entering Muscat Bay at the beginning of Muscat Bay.
L2: Sub BULK Watermeter
Measures water distribution to different zones. Each Sub BULK Watermeter is located at the entrance of each zone and measures the combined usage of all individual meters (L3) within that zone.

2.2 Relationships Between Metering Levels
L1 = Total of L2
L2 = Total of L3
L1 = Total of L3
2.3 Implications of Water Consumption Differences
Difference between L1 and L2: Indicates water loss or leaks in the common areas of Muscat Bay.
Difference between L2 and L3: Indicates water loss or leaks inside the zones.
Total water loss on a monthly basis = (L1 - L2) + (L2 - L3)
