What This File Documents
Drought, network loss and rationing require different evidence. Follow the water record from restrictions to infrastructure and measured supply.
EXPLICITLY IN SCOPE
Infrastructure and distribution. Documentary history, implementation and evidence limitations.
DELIBERATELY OUTSIDE SCOPE
A national reservoir reading does not identify the cause of an individual household interruption.
Current Overview
Latest supported material is Summer 2026. This is descriptive; it is not a comparison period or an evidence-through date. Latest comparable period: Summer 2026.
Latest comparable observations
FACTComparable observationSummer 2026
Desalination Eases Coastal Stress but Network Losses (~30%) and Interior Scarcity Persist
Desalination output relieved peak summer pressure in Sfax and Gabès urban centers, but national dam reserves remained at ~21-25% capacity in Summer 2026, and physical pipe network losses were estimated at ~30% nationally.
No comparable observation for a later period is represented in this selected dossier.

Desalination Eases Coastal Stress but Network Losses (~30%) and Interior Scarcity Persist
Desalination output relieved peak summer pressure in Sfax and Gabès urban centers, but national dam reserves remained at ~21-25% capacity in Summer 2026, and physical pipe network losses were estimated at ~30% nationally.
Causal attribution: CONTRIBUTING_FACTOR. Desalination directly provided new supply volumes; however, persistent drought is climate-driven and network leakages reflect multi-decade infrastructure under-investment.
2019 marks the beginning of Kais Saied’s presidency, not the beginning of these systems or their problems. Preserve the reference period when comparing outcomes.
DATA GAP · A comparable 2019 series is not established by the selected evidence.

FACTHistorical Context2023-03-31 · ISS-WATER-01
Ministry of Agriculture Issues Decision No. 1303 Imposing Potable Water Quotas and Nightly Cuts
Ministerial Decision established emergency water rationing, prohibiting the use of potable water for agriculture, car washing, public green spaces, and mandating overnight water shutoffs (typically 21:00 to 05:00).
Indefinite Extension of Water Quotas and Rationing Regime
Due to continued deficit in dam inflows, the Ministry of Agriculture extended Decision 1303 indefinitely until further notice, keeping nighttime cuts operational nationwide.
Public Capital Financing for Seawater Desalination Plants (Zarat, Sfax, Sousse)
Mobilization of ~1.5B TND in public investments and concessional loans (JICA, KfW, AFD) to complete major desalination plants: Zarat (Gabès - 50,000 m³/day), Sfax (100,000 m³/day), and Sousse (50,000 m³/day).
Commissioning of Zarat and Sfax Desalination Plants
Commercial operation commenced at the Zarat plant (July 2024) and the Sfax desalination plant (August 2024), adding 150,000 m³/day of non-conventional potable water to the southern and coastal networks.
Desalination Eases Coastal Stress but Network Losses (~30%) and Interior Scarcity Persist
Desalination output relieved peak summer pressure in Sfax and Gabès urban centers, but national dam reserves remained at ~21-25% capacity in Summer 2026, and physical pipe network losses were estimated at ~30% nationally.
Causal attribution: CONTRIBUTING_FACTOR. Desalination directly provided new supply volumes; however, persistent drought is climate-driven and network leakages reflect multi-decade infrastructure under-investment.
How did the state manage consecutive years of severe drought, what legal restrictions were imposed, and how did desalination plants and leakage reduction programs perform?

NOT ESTABLISHED
A national reservoir reading does not identify the cause of an individual household interruption.

Governorate-by-Governorate Water Loss and Pipe Replacement Ledger Unpublished
SONEDE has not published an open, transparent delegation-level data registry detailing annual pipe replacement linear meters and physical versus commercial water loss percentages.
Aggregate national loss is quoted between 28% and 34%, but granular municipal network telemetry remains unavailable.
Comparable 2019 reservoir, network-loss and interruption series are not linked in the selected archive. No delegation-level Summer 2026 interruption ledger is available here.
This is a bounded inventory gap, not a claim that no such data exists anywhere.
