Historical resource assessments and sector-use observations retain their stated dates and definitions; no new national water balance or source estimate is introduced.
Bahrain's public drinking-water production and its wider water-resource system have different boundaries. The Electricity and Water Authority reports that public drinking-water supply became fully reliant on desalination in 2016, with groundwater reserved for contingency. That operating description does not mean that agricultural groundwater use or the national aquifer relationship disappeared.
The distinction becomes particularly useful when reading a production dataset. The 2025 public-supply account records zero groundwater production within that system, identifying the source mix of an institutional service. It does not establish zero abstraction across every sector or remove groundwater from the national resource landscape that other institutions describe.
The authority's June 2026 supply description identifies six desalination plants and stated production capacity of 213 million imperial gallons per day. This gives a reference for the public production system's scale. It describes capacity, rather than annual water actually used or a calculation incorporating future plants still at tender stage.
The supply chain extends beyond the plants themselves. The authority reports 622 kilometers of transmission pipelines linking production to 48 forwarding and distribution stations, connecting the source model to delivery infrastructure. Customer service points and local distribution perform further functions, so transmission length should not be presented as the complete length of every customer pipe.
Groundwater belongs to a different resource account. Published descriptions identify the Dammam and Rus-Umm Er Radhuma aquifer systems, while the regional assessment connects Bahrain's groundwater context to geological formations beyond its national boundary. This helps explain why lateral inflow, abstraction pressure and salinity remain relevant even within a desalinated public drinking-water model.
A 2013 regional assessment identifies over-pumping and seawater intrusion as concerns for the aquifer system. Its historical Bahrain reference reports Dammam abstraction of 97 million cubic meters in 2010 against a safe-yield reference of 90 million. These are dated resource observations, not a newly measured operating balance for the public network.
Sector withdrawal shares provide another national reference. The published international series gives domestic use at 63.44 percent, agriculture at 33.31 percent and industry at 3.25 percent, repeated throughout 2016–2022. That composition concerns freshwater withdrawal, with the carry-forward pattern preventing the values from proving unchanged behavior through fresh measurements every year.
Wastewater introduces a third resource pathway. The Ministry of Works identifies treated-effluent supply points at Tubli, Sitra and Muharraq, while the adaptation account discusses productive use and future conveyance. Treatment capability, suitable quality, a route to users and actual reuse are connected stages, rather than alternative names for the same water-volume measurement.
The institutional landscape follows that wider system structure. The Electricity and Water Authority manages public services, while wastewater, agricultural resources and environmental responsibilities involve other bodies. The National Water Strategy 2030 emphasizes coordination, monitoring and awareness because national water questions extend beyond the operation of the potable production network alone.
This wider account also changes how scarcity indicators should be read. The published international freshwater-stress estimate of 152.5 percent for 2023 concerns renewable-resource pressure under its stated statistical treatment. It is distinct from whether an engineered desalination system can deliver public drinking water, so a functioning supply service and resource stress can coexist.
For a researcher beginning work on Bahrain, the appropriate boundary depends on the subject. A public-supply investigation starts with production and networks, while an agricultural-resource inquiry needs groundwater and withdrawal evidence. A reuse question follows treatment, conveyance and suitable demand, bringing another set of institutions and operating references into view.
The useful national picture therefore connects the systems without merging their statistics. Desalination explains public potable supply, groundwater retains a regional resource and use relationship, and treated wastewater offers a further pathway where suitable infrastructure and users exist. Preserving those functions gives a clearer reference for further research than interpreting a zero public-groundwater production row as the end of all groundwater activity.
Does desalinated potable supply mean groundwater use has ended?
No. The potable-supply account and the wider resource account cover different activities. Bahrain’s public supply reference describes desalination, while agriculture and groundwater management remain separate parts of the national system. A zero groundwater contribution to a particular public-supply account does not establish zero abstraction across all sectors.
What does the stated desalination capacity measure?
The June 2026 authority account identifies six plants and capacity of 213 million imperial gallons per day. It describes production capability in a specified unit and system account. It does not independently establish daily delivered consumption, aquifer condition or the additional capacity proposed through future tendered developments.
Are the historical aquifer references current readings?
The regional aquifer references retain their historical assessment periods, including the 2010 and 2013 material discussed in the Profile. They contribute resource context. Treating those observations as newly measured conditions would obscure their date and convert an existing research reference into an unsupported present-day assessment.
How should the repeated sector-use shares be interpreted?
The 63.44, 33.31 and 3.25 percent shares appear as carried-forward observations across the stated 2016–2022 account. Their repetition does not establish a fresh measurement for each year or a changing trajectory. The useful reference preserves the series’ published basis rather than manufacturing annual movements from repeated values.
Does water stress describe an immediate supply outage?
The freshwater-stress measure concerns its stated resource-use basis, which differs from the operating account of desalinated public supply. A value such as the separately reported 152.5 percent reference cannot be read directly as an outage forecast. Connecting resource pressure to service reliability would require additional compatible evidence and a specific analytical question.
