Over the past 12 months, 4,466,750 litres of Aquacomb water storage has been installed across New Zealand. These have managed an estimated 220 million litres of water over the year. 

This figure is based on internal system capacity calculations across approximately 3,800 installations between 1 April 2025 and 31 March 2026. It reflects a combination of both detention and retention. In simple terms, that is water being temporarily stored and released in a controlled way, or held for non-potable reuse within the property. 

On its own, each system contributes a relatively small volume. But when you step back, the scale becomes clearer. Across thousands of sites, this works out to roughly 60,000 litres per property last year. 

Around the world, leading cities are adopting a more integrated approach: designing urban environments to behave like sponges — absorbing, storing, filtering and gradually releasing rainwater rather than immediately channelling it away.

Hot, dry summers put pressure on mains water, but slimline rainwater storage makes every downpour count. This guide covers FenceTank, stormPANEL, and Silo systems that fit tight sites while supporting gardens, outdoor play, and everyday non-potable use. Learn how to plan capacity, connect plumbing compliantly, and scale storage before restrictions hit.

Plan smart water detention and rainwater reuse systems for NZ summer. Compare tanks, Aquacomb, lead times, capacities, and council compliance.

Watersmart Wins Prestigious National Innovation Award for Stormwater Solution Porous Lane

The New Zealand government has announced a comprehensive overhaul of infrastructure funding mechanisms to bolster housing development. This initiative, part of the “Going for Housing Growth” strategy, seeks to address critical challenges in land supply, infrastructure, and growth incentives. 

Auckland’s Rainfall Brings Temporary Relief, but Drought Concerns Persist

New Zealand’s urban development is increasingly constrained by aging and overburdened infrastructure. Developers often face high costs, shared investment

Experts and councils across Aotearoa are increasingly calling for the widespread adoption of water metering to help New Zealand better manage its water use

Next week is World Water Week, held since 1991 in Stockholm. Find out how Watersmart contributes to the theme this year.

Water metering is a crucial tool for building owners and developers aiming to achieve a NABERS (National Australian Built Environment Rating System) rating, particularly for water efficiency. NABERS ratings are essential for demonstrating a building’s environmental performance and sustainability, and water metering plays a pivotal role in this process.

Winter has well and truly arrived bringing with it the cold and the rain. It has also unfortunately brought flooding, with a State of Emergency being declared

Recent reports from water regulator, Taumata Arowai, showed that nearly half a million Kiwis do not have access to safe drinking water.
