Global Water Charges Rise as Utilities Meet Stricter Regulations

OXFORD, United Kingdom, Oct. 28, 2026 /CourierPR/ -- Global Water Intelligence’s latest Global Water Tariff Survey 2026, the largest to date with data from 1,069 cities across 189 countries, reveals a significant trend in wastewater charges. Utilities worldwide are grappling with rising costs, driven by stricter discharge regulations and the need to build out sewer networks.

In mainland Malaysia, Indah Water Konsortium has nearly doubled domestic sewerage charges since 2023, making them higher than water charges. This move reflects the increasing costs associated with wastewater management. In Dubai, wastewater charges were raised in 2025 for the first time in nearly a decade, with more increases expected. Bahrain introduced its first sewage fee, signaling a shift in how utilities finance their operations.

Scandinavian cities are also seeing changes. Fredrikstad, Aarhus, and Malmö are shifting charges from water to wastewater. In Malmö, the wastewater charge has risen by 39.3%, highlighting the financial burden of upgrading and maintaining wastewater systems.

These rising charges have several implications for the water industry. In Dubai, the increases are helping fund one of the world’s largest urban drainage programmes. The $8.16 billion Tasreef stormwater programme and the $6.8 billion Strategic Sewerage Tunnels are well into procurement. In Honolulu, new rates are aimed at funding a $10.1 billion capital programme, which includes a federally mandated treatment plant upgrade. These projects underscore the significant investment required in wastewater infrastructure.

The trend of increasing wastewater rates is driven by several factors. Wastewater technologies are more expensive to build and operate than water systems, and sewer networks are still being built out. Environmental discharge pressures are also mounting, necessitating stricter regulations and more robust treatment facilities.

These changes are expected to have a ripple effect on the broader water industry, pushing utilities to become more financially independent from central government support. The survey provides a comprehensive view of the financial landscape in the water sector, offering insights into the challenges and opportunities facing utilities globally.
