The Auditor-General of South Africa, in the Consolidated General Report on Local Government Audit Outcomes 2024/25 (published June 2026), found Johannesburg's water losses "remained above the 30% norm for the past four years, with recent levels consistently reaching over 45%", and that the city lost R10.3-billion worth of drinking water in four years
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.

src-2ef9bb61a007e1b8Verifies the primary figure against the source document: "Johannesburg Water's 2023/24 annual report recorded a non-revenue water figure of 46.2%", with the breakdown 24.8% physical losses, 9.7% commercial losses, 11.7% unbilled authorised consumption. Used because johannesburgwater.co.za returns 403 to automated fetching.
src-4f36bfc7bf6cd3ccThe independent grade. Quotes the AG's Consolidated General Report on Local Government Audit Outcomes 2024/25: losses "remained above the 30% norm for the past four years, with recent levels consistently reaching over 45%"; "Johannesburg has lost R10.3-billion worth of drinking water in four years"; "failure to proactively maintain its water infrastructure"; material irregularity notified December 2024.
src-190d9c3647d190b4Operator-reported instrumentation counts, carrying Johannesburg Water's own statement of the same date: 15 smart pressure controllers commissioned in 2023/24, 13 more by April 2025, 53 to date, 306 being installed to end-September 2026; 225 noise loggers installed, 125 more by October 2026; smart hydraulic flow controls on 28 high-consumption reservoirs and towers. Logan Munsamy, Senior Manager for Water Demand Management and Technical Metering, quoted on lowering minimum night flow losses.
src-1edc73a20337425cCurrent state and money: Executive Mayor Dada Morero on the city needing to reach 1 550 Ml/d to comply with Rand Water licence apportionment; R1.7-billion 2026 budget against a R27-billion infrastructure backlog; night-time throttling, bulk meter restrictions and leak detection as the active toolkit.
src-4e63faca1f82f33bTelemetry layer, in the utility's own words: "JW employs a 24-hour telemetry system with two control rooms staffed around the clock", monitoring "signals from reservoirs and pump stations, alerting staff to issues such as power failures or low water levels". Also attributes consumption misreading to ageing meters.
src-b73371ac38b4a6b7Independent academic on the bulk-versus-distribution split: "a mismatch between what's allocated by the national government and what's needed on the ground"; maintenance bill of R2-billion a year against R1-billion allocated; Lesotho Highlands Phase 2 eight years late. NOTE: this source's 49.2% non-revenue water and 279 l/person/day are GAUTENG PROVINCE figures and are deliberately not used as Johannesburg figures in this entry.
