Smarter Pool Design: Cutting Energy Costs in Aquatic Centres

Energy efficiency is no longer optional for aquatic centres. It’s a necessity!

Rising utility costs and stronger sustainability expectations are putting pressure on operators to find new ways to reduce expenses while maintaining safe, enjoyable facilities.

We spoke with the team at Waterlink, who shared practical insights on how technology upgrades can make a real difference, not just for new builds, but also for existing pools looking to reduce running costs.

One of the most effective solutions is filtration systems fitted with Variable Frequency Drives (VFDs). These allow pumps to slow down overnight or during off-peak times, cutting electricity use without compromising water quality. For facilities with large pump loads, this translates to measurable savings year after year. Crucially, VFDs can be retrofitted to many existing systems, making them a straightforward upgrade path.

Another opportunity is on-site chlorination with Envirogen. Instead of relying on bulk chlorine that must be manufactured and transported by diesel trucks, Envirogen generates chlorine at the facility itself. This reduces environmental impact, ensures a consistent supply, and removes the risk of shortages. All while lowering long-term costs.

Simple monitoring improvements can also yield big wins. For example, tracking manifold filter pressures and backwashing only when needed saves significant amounts of water, reduces heating demand, and lowers chemical use. These measures improve efficiency without affecting water quality.

Secondary sanitation such as Advanced Oxidation Processes (AOP) provide an extra layer of water quality assurance. AOP helps break down organics and minimise chloramines, creating healthier environments for swimmers and staff. While often associated with new installations, AOP systems can also be integrated into existing plant rooms.

The Waterlink team emphasises that energy-efficient aquatic centres aren’t only built from scratch, they can also be achieved by upgrading existing infrastructure. From filtration to disinfection, demand-driven and on-site systems offer clear pathways to lower costs, reduced energy use, and extended equipment life.

For operators facing rising overheads, the message is clear: significant savings are possible with the right technology choices, whether you’re building new or modernising an established facility.
