Tareno Water Fund: Develo­p­ment of the water sector in November 2025

Political Frame­work: From Regula­tion to Invest­ment

Two key policy develo­p­ments shaped the landscape in November:

1. Europe: Climate-resilient infras­truc­ture: Discus­sions around decar­bo­ni­sa­tion in Europe made one point unmist­akably clear: without reliable and secure water availa­bi­lity, neither the energy transi­tion nor industrial expan­sion plans can be reali­sti­cally imple­mented. Invest­ment in resilient water infras­truc­ture is becoming an unavo­idable neces­sity.
2. United Kingdom: Regulated invest­ment momentum: Despite ongoing public scrutiny and regula­tory debate, UK utili­ties are required to carry out multi-billion-pound invest­ment programmes. The pressure to moder­nise ageing infras­truc­ture remains immense.

By contrast, the United States conti­nues to exhibit struc­tu­rally elevated invest­ment needs. Even as certain environ­mental standards were relaxed at the federal level, issues such as PFAS remedia­tion, the renewal of ageing water networks and, incre­a­singly, the rising water demand of the data-centre industry, are driving a signi­fi­cant and sustained invest­ment cycle across the sector.

Market Develo­p­ments and Corpo­rate Updates

Compa­nies across the water sector are respon­ding to these struc­tural drivers with a clear focus on innova­tion and opera­tional effici­ency.

A compel­ling example comes from SABESP, the water utility of São Paulo, which announced a large-scale leakage-reduc­tion programme. In colla­bo­ra­tion with Amazon Web Services and Aganova, appro­xi­m­ately 64 kilome­tres of pipelines will be inspected over the next ten years, with expected annual water savings of around 210 million litres. Beyond its environ­mental value, the initia­tive is econo­mic­ally attrac­tive: every leak avoided reduces energy consump­tion, opera­ting costs and future capital expen­diture requi­re­ments.

The shift is even more prono­unced in the field of water quality testing. Veralto streng­thened its leader­ship in real-time water monito­ring through the acqui­si­tion of a specia­list in water-quality analy­tics. The sector is moving rapidly toward data-driven value creation. Those who provide the most reliable measu­re­ments will set the standards, shaping effici­ency gains, regula­tory compli­ance and cost struc­tures across the value chain.

A similar dynamic is evident at Itron. With a major digital infras­truc­ture contract awarded in the United Kingdom, the company reaffirmed that smart metering is well on its way to becoming a global industry standard. Political pressure to reduce water losses, combined with utili­ties’ opera­tional need for trans­pa­rency, conti­nues to reinforce this trend. Networked metering systems not only enhance opera­tional effici­ency but also open the door to advanced manage­ment tools—from demand-respon­sive network opera­tions to usage-based tariff struc­tures.

ESG-Update: COP-30 & SFDR-Reform

COP-30 concluded on 22 November with a pledge to triple global finan­cing for climate-adapt­ation measures by 2035, corre­spon­ding to annual funding of roughly USD 1.3 trillion. In parallel, the European Commis­sion presented on 19 November the most compre­hen­sive reform proposal for the Sustainable Finance Disclo­sure Regula­tion (SFDR) since its intro­duc­tion. The existing Article 8 and Article 9 catego­ries are to be replaced by three new classi­fi­ca­tions: Transi­tion, ESG Basics, and Sustainable.

Fund Perfor­mance & Outlook

The W‑EUR share class of the Tareno Global Water Solutions Fund returned –0.03% in November. Despite the slightly negative monthly perfor­mance, the Fund remained resilient in a volatile market environ­ment. The solid develo­p­ment of water-sector compa­nies conti­nues to validate our long-term invest­ment thesis.

The recently renewed expec­ta­tion of a Federal Reserve rate cut in December is likely to support markets, and we there­fore antici­pate a construc­tive end to the 2025 calendar year. We remain committed to our defen­sive positio­ning.
