Parts of this claim

The claim is split into parts that are tested separately, as in the report below. Each part has its own number.

  1. CC-039A Groundwater abstraction “will be reduced by 4 billion litres per year” (WSC [1])No baseline year or date. Against 2016, WSC groundwater production is lower by 0.3–2.0 million m³ in 2022–25 (9–49% of 4.0), lowest in 2025.No baseline or date
  2. CC-039B Desalination produces “much more water with less energy” (WSC [1])More water: RO output +50% since 2016. Less energy per m³: whole-utility energy per m³ produced 4.68 (2022) to 4.60 (2024) kWh/m³ [8], a 1.7% fall; RO plant figures by year not found; RO electricity likely higher in total.Mixed
  3. CC-039C Extra production without increasing the utility’s overall net power requirements (WSC framework, as described in [3])RO alone would need a third lower specific energy to stay flat. Whole-utility kWh not published; intensity 4.68 to 4.60 kWh/m³ (2022–24) while production rose 9%, so total energy likely up [8].Not testable as worded

A net-zero-impact water utility?

Testing WSC’s promise of 4 billion litres less groundwater and less energy per litre

“The Corporation’s ground water abstraction will be reduced by 4 billion litres per year.”

Water Services Corporation, news release, 2 April 2019.
Same release: desalination upgrades mean “much more water with less energy”.

Verdict: Not measurable As of 6 Oct 2026: no baseline, date or boundary stated

Version 1.1 · 6 October 2026

TL;DR

In a statement of 2 April 2019 [1], the Water Services Corporation (WSC) said that the EU part-financed Net Zero Impact Utility project would cut its groundwater abstraction “by 4 billion litres per year” and produce “much more water with less energy”. The project’s framework has also been described as letting extra production be met “without increasing the overall net power requirements” of the utility [3]. We tested these statements against WSC’s own production reports and Eurostat.

  1. The groundwater pledge has no baseline and no date. 4 billion litres is 4.0 million m³, about 30% of the 13.5 million m³ WSC took from boreholes in 2016 [4]. WSC does not say from which year, or by when.
  2. Measured against 2016, the cut so far is real but partial. WSC groundwater production was 11.5 million m³ in 2025 [6], 2.0 million m³ below 2016: about half the pledged amount. In 2023 and 2024 it was only 0.3–0.4 million m³ below. Eurostat’s public-supply series is 1.0–1.2 million m³ lower in 2024 than in 2018–19 [7].
  3. More water now comes from desalination, which costs energy. Reverse-osmosis output rose about 50% between 2016 and 2025 (18.6 to 27.9 million m³) [4, 6]. At the 2016 specific energy that is about 45 GWh more electricity a year; to stand still, specific energy would have to fall by a third.
  4. Pledge label: not measurable (as of 6 October 2026). Neither promise states a baseline, boundary or date, and WSC’s total electricity use by year was not found. That is a gap in what WSC published, not a finding of failure.

What would make it measurable or on track

A stated baseline year and completion date for the 4 billion litre cut, and WSC’s total electricity use (kWh) by year on a stated boundary, showing it flat or falling while production rose.

What would count against it

WSC’s own series showing groundwater production back near 13 million m³ with the project complete, or metered electricity use rising with production.

IN THIS REPORT

1 The statements and their sources

Our candidate record combined several statements from different documents. We read two WSC pages (through the Internet Archive, because wsc.com.mt shows a bot challenge to scripts) and a peer-reviewed overview by an Energy and Water Agency author, and separate what each says.

SourceWordingStatus
WSC news release, 2 April 2019 [1]“The Corporation’s ground water abstraction will be reduced by 4 billion litres per year.” Also: the capacity and efficiency of the desalination plants “are being upgraded thereby producing much more water with less energy”.Primary wording (verbatim)
WSC project page, 16 April 2018 [2]Describes the project’s components (more efficient RO plants, many more remotely monitored boreholes “rested” as needed, a new RO plant at Ħondoq, a tunnel from Pembroke to Ta’ Qali). Says the tunnel will save “approximately 3.5 Giga Watts of energy” (sic) and about 1,800 t of CO₂ a year. No groundwater volume.Primary; context
Sapiano (Energy and Water Agency), Acque Sotterranee 2020, p. 30 [3]Describes WSC’s “Net-Zero Impact” framework (citing WSC 2018, which we did not read): it aims to “enable any increased production to address water demand to be met without increasing the overall net power requirements of the water utility”.Second-hand description of WSC’s aim

WHAT THIS CHECK DOES NOT COVER

The idea that the utility gives back to the aquifer “at least as much” water as it abstracts is a different statement, tracked as Claim Check 108. “No net increase in energy use”, as our candidate record put it, is not WSC’s wording in either page we read; it paraphrases the framework as Sapiano describes it [3]. We treat it as that and say so.

2 Method

Question. Is there evidence that WSC’s groundwater abstraction has fallen by 4 billion litres a year, and that it produces more water without more energy? Can either promise be checked as worded?

Groundwater. 4 billion litres = 4.0 million m³ (1 m³ = 1,000 litres). We compare it with WSC’s reported groundwater production: 2016 from WSC’s 2016 annual report [4] (the last report before the project framework that we read), and 2022–2025 from the 2025 report’s production chart [6], transcribed for Claim Check 009 (WSC’s 2022 report gives about 12.7 million m³ for 2022 [5], the same). We also use Eurostat’s public-supply groundwater abstraction for 2018, 2019 and 2024 [7] (estimated values, a different measure that runs about 1 million m³ above WSC’s own series). Years 2017–2021 were not read.

Energy. WSC’s 2016 report gives the specific power of its RO plants (4.85 kWh/m³) [4]. We multiply volume by specific energy for 2016, and for 2025 show a scenario holding the 2016 specific energy, and the level (3.24 kWh/m³) that would keep RO electricity flat. WSC’s Impact and Allocation Report for 2024 [8] gives a whole-utility energy figure per cubic metre produced for 2022–2024 (read first-hand, the relevant pages); we found no total kWh for the whole utility. WSC’s Annual Report 2024 could not be opened. Code: tools/cc-039-report/calc.py; results in data/cc-039/checks.csv.

Grades. WSC’s annual reports are self-reported company documents (C); Eurostat figures are official statistics, flagged as estimates (C); our arithmetic is an order-of-magnitude check and is labelled as such.

3 Groundwater: what the data show

Figure 1. WSC groundwater production (boreholes and pumping stations, Malta and Gozo) against the level the pledge would imply if the baseline were 2016.

MeasureBaselineLatestChangeShare of the 4.0 pledged
WSC groundwater production, 2016 → 2025 [4, 6]13.5111.54−1.9649%
WSC groundwater production, 2016 → 2024 [4, 6]13.5113.09−0.4110%
Eurostat public supply, 2018 → 2024 [7]15.2414.28−0.9624%
Eurostat public supply, 2019 → 2024 [7]15.5214.28−1.2431%

All volumes in million m³. A full 4.0 million m³ cut from the 2016 level would leave 9.5 million m³; no year we read is near that.

READING THE NUMBERS

The 2025 figure is the lowest we have, and WSC attributes lower groundwater use to a lower-salinity blend and more RO water [5, 6]. It follows a 2024 value only 0.4 million m³ below 2016, so one year is not yet a trend. WSC groundwater is also a small part of national abstraction: 4.0 million m³ is about 10% of Malta’s 38.5 million m³ of fresh groundwater abstracted in 2024 (Eurostat, estimated), most of it by agriculture [7].

Fairness to WSC

  • Its groundwater share of production fell from 42% (2016) to 29% (2025) while total production grew by about 23% (32.1 to 39.5 million m³) [4, 6]. Put against demand growth, the groundwater cut is larger than the raw change suggests.
  • WSC’s 2022 report describes reactivating eight boreholes or pumping sources by 2022 to spread abstraction (to relieve local pressure) [5]. Spreading abstraction is a quality aim; it does not by itself reduce volume.
  • The 2019 statement gave no baseline or date; we chose 2016 as a published pre-project reference and other choices move the result.

4 Energy: what the data show

Ħondoq RO specific energy 20243.11 kWh/m³ (2021 baseline 4.1)WSC Impact and Allocation Report FY2024, pp. 24, 28 [8]

The whole-utility figure is WSC’s “Total Energy Requirement per m³ produced”; the report does not define its boundary, so it is not comparable with the 2016 RO figure (4.85 kWh/m³). Implied total = intensity × production (groundwater + RO, WSC AR 2025 Fig 20), assuming “produced” means that production.

What the energy data mean

  • “Much more water with less energy” can be read per cubic metre. On that reading, the only like-for-like series we have is WSC’s whole-utility energy per m³ produced, 4.68 (2022), 4.52 (2023), 4.60 (2024) kWh/m³ [8]: a small fall that is not steady, and not comparable with 2016’s RO-only 4.85. The Ħondoq plant, which WSC says uses 23.5% less energy than conventional plants [5], serves a small share of output (5.0% of RO water in 2022 [5]).
  • “Without increasing the overall net power requirements” is a total, not a per-unit, claim. RO output grew by half; a fall of a third in specific energy would be needed to keep RO electricity flat. The figures we have point the other way: WSC’s whole-utility intensity barely moved from 2022 to 2024 while production rose 9%, which implies more total energy (indicative; boundary not defined in [8]). WSC’s own 2022 report says its expenditure rose by about €2 million in energy consumed, which it ties to “a strategic decision to improve potable water quality by increasing the production from its reverse osmosis plants” [5].
  • The offsetting savings WSC cites are small. The Pembroke–Ta’ Qali tunnel is said to save about 3.5 GWh a year (WSC writes “Giga Watts”) [2], against an RO increase of tens of GWh. WSC’s figure is its own estimate.
  • We could not test the whole utility. Groundwater pumping, sewage treatment and distribution energy, and any renewable generation, are outside our RO estimate, and no total kWh by year was found.

6 Pledge label and requests for evidence

PledgeNot measurable

As of 6 October 2026. No baseline, date or boundary stated; indicators move the right way for groundwater and the wrong way for RO energy.

Why. Both promises are statements of intended outcome. The groundwater promise names an amount but no starting year and no completion date; the energy promise names no baseline, boundary or date. A pledge is not a statement of fact, so we do not call it false. As worded it cannot be shown to have been met or missed, so we label it Not measurable (Appendix A lists the six pledge labels). Our indicative figures are given so readers can see where the data point.

What this label does not say. It does not say the project failed, that WSC’s figures are wrong, or that the aim is undesirable. Water security and lower energy intensity are sound goals. A checkable version would read: “Compared with [year], WSC’s groundwater production will fall by 4.0 million m³ a year by [date], while its total electricity use stays at or below [X] GWh.”

Evidence we are asking for

  • From WSC: the baseline year and completion date behind “4 billion litres per year”, and annual groundwater abstraction by source since 2014.
  • From WSC: total electricity consumption (kWh) by year, split by RO, groundwater pumping, distribution and sewage treatment, and the boundary of “net zero” impact on energy.
  • From WSC: whether all components of the Net Zero Impact Utility project are complete, and the 2018 framework document that Sapiano [3] cites.
  • From WSC: the specific energy of each RO plant by year, and the boundary of the “Total Energy Requirement” indicator.

RIGHT OF REPLY

Before wider circulation this draft should be sent to the Water Services Corporation with a fixed deadline (suggested 14 days). Responses will be appended and the label revisited.

7 Limitations

  • WSC’s 2016 and 2025 production series come from different reports; we did not verify that definitions match (WSC’s 2022 report agrees with the 2025 report for 2022). Years 2017–2021 were not read.
  • The 2025 values are read from a chart and carry the small internal differences recorded for Claim Check 009.
  • WSC’s Annual Report 2024 could not be opened (parlament.mt refuses scripts; no archive copy found). Its Impact and Allocation Report for 2024 [8] was read (relevant pages) and gives the energy figures used. A search-engine summary had given 4.68 kWh/m³ as an RO figure for 2024; the report shows it is the whole-utility figure for 2022, so it is not used.
  • The RO electricity estimates are volume times specific energy, not metered totals.
  • We did not establish which project components were complete, or when. The live wsc.com.mt pages show a bot challenge to scripts; both WSC pages were read in Wayback copies of 2024.
  • Sapiano’s description of the framework cites a WSC 2018 document that we did not read.

MISLEADINGOmits material facts so that the overall impression is inaccurate, even if individual statements are defensible.
CONTRADICTEDThe available evidence points against the claim.

Pledge labels

A pledge is a promise of future action, so it cannot be true or false when it is made. It gets one of these labels instead of a verdict, with the date of the evidence behind it.

Pledge labelMeaning
