Of the 162 million m3 of water that National Water and Sewerage Corporation (NWSC) supplied in FY 2022/23, 101.9 million m3, or 62.9%, went into the Kampala Water area. Kampala's supply rose to 104.1 million m3 in FY 2023/24.
Losses concentrated in the capital
Non-revenue water across NWSC was 33.9% in FY 2023/24. The regional figures show where that comes from: Kampala Water lost 39.8%, while the Central area lost 23.2%, Eastern 20.5%, Northern 24% and Western and South Western 25%. In FY 2022/23, about 57 million m3 of the water NWSC supplied was not sold.
Little change since 2021
Kampala's loss rate has barely moved. The Ministry of Water and Environment reported Kampala Metropolitan non-revenue water at 40.6% at 30 June 2021. On the Ministry's regulator scorecard it was 41.3% in FY 2021/22 and 40.8% in FY 2022/23, against a 41.7% target. NWSC's own figure for FY 2023/24 was 39.8%.
The 2030 target
NWSC's 2025–2030 Strategic Plan aims to bring non-revenue water down to 28% by 2030, from 34% in FY 2024/25. Kampala carries most of the volume and the highest loss rate, so its results will weigh most on whether that target is met.
