Energy efficiency is no longer optional for aquatic centres, it’s a core operational requirement. Rising energy prices, increasing compliance obligations, and stronger sustainability expectations are driving operators to find practical ways to reduce costs without compromising water quality, safety, or user experience.
With the right system design and targeted upgrades, both new and existing facilities can achieve meaningful reductions in energy consumption and operating costs.
Optimising Filtration with Variable Frequency Drives (VFDs)
One of the most effective ways to reduce energy use in aquatic facilities is through filtration systems fitted with Variable Frequency Drives (VFDs).
VFDs allow pumps to operate at reduced speeds during low-demand periods, such as overnight or outside peak bather loads. This significantly cuts electricity consumption while maintaining required turnover rates and water quality standards. For facilities with high pump loads, the long-term energy savings can be substantial.
Importantly, VFDs can often be retrofitted to existing filtration systems, making them a practical upgrade path for facilities looking to improve efficiency without a full plant room rebuild.
Reducing Chemical and Transport Costs with On-Site Chlorination
On-site chlorination is another proven strategy for lowering both operational costs and environmental impact.
Instead of relying on bulk chlorine that must be manufactured, transported, and stored, on-site systems such as Envirogen generate chlorine directly at the facility. This reduces reliance on chemical deliveries, improves supply consistency, and significantly minimises chemical handling risks.
For many operators, on-site chlorine generation delivers long-term cost savings while supporting safer plant room operations and more sustainable pool management.
Smarter Monitoring for Water and Energy Savings
Efficiency gains don’t always require major equipment changes. Improved monitoring and operational control can also deliver strong results.
Monitoring filter manifold pressures and backwashing only when required can significantly reduce water consumption, heating demand, and chemical use. Avoiding unnecessary backwashing helps retain heat in the system, lowers replacement water volumes, and reduces overall energy load — all without compromising water quality or compliance.
These types of demand-driven operational improvements are often among the fastest ways to achieve measurable savings.

Enhancing Water Quality with Secondary Disinfection (AOP)
Secondary disinfection technologies, including Advanced Oxidation Processes (AOP), provide an additional layer of water quality protection.
AOP systems help break down organic contaminants and reduce chloramine formation, improving air quality and creating healthier environments for swimmers and staff. While commonly specified in new aquatic centre builds, AOP systems can also be integrated into many existing plant rooms as part of a staged upgrade approach.
For facilities aiming to improve swimmer comfort while maintaining efficient primary disinfection, secondary disinfection can play a key role.

Upgrading Existing Infrastructure for Long-Term Efficiency
Energy-efficient aquatic centres aren’t only achieved through new construction. Many facilities can significantly improve performance by upgrading existing infrastructure.
From filtration and pumping to disinfection and monitoring, demand-driven and on-site systems provide clear pathways to lower energy use, reduced operating costs, and extended equipment life. When upgrades are planned strategically, facilities can achieve meaningful improvements without major disruption.
Making Smarter Technology Choices
For aquatic centre operators facing rising overheads, the message is clear: substantial savings are possible with the right technology choices.
Whether designing a new facility or modernising an established one, investing in efficient, scalable systems delivers long-term benefits for operational performance, sustainability, and user experience.
Want to Reduce Energy Costs in Your Aquatic Facility?
