Status - Active Programme
A structured, multi-site evaluation programme assessing how Integro™ technology can support asset protection, hot water performance, and operational resilience across premium health and leisure facilities.
“Supporting reliable hot water, protected plant assets, and high-quality member experience across busy leisure environments.”
Overview
The David Lloyd Clubs programme represents a structured evaluation of Sidon Water Integro™ technology within high-demand health and leisure environments.
Selected clubs were identified based on their water system configuration, daily hot water demand, hard-water conditions, and suitability for practical technical assessment. The programme is designed to evaluate how Integro™ can support limescale control, protect key assets, and help maintain reliable domestic hot water performance across a range of David Lloyd site types.
Each site has undergone a detailed technical survey, with installation locations selected to provide targeted treatment coverage while minimising disruption to club operations. Follow-up inspections and site feedback form an important part of the programme, allowing Sidon Water and David Lloyd Clubs to review outcomes in real operating environments.

Timeline & Project Details
Phase 1 – Site Surveys & Technical Assessment
Sidon Water carried out detailed site surveys at selected David Lloyd Clubs to understand each site’s domestic cold water and hot water configuration.
The surveys assessed:
- Cold water storage and booster arrangements
- Hot water generation and recirculation systems
- Calorifiers, plate heat exchangers and associated pipework
- Existing water treatment arrangements
- Areas where limescale control could support asset protection
- Opportunities for performance review and future validation
Each site presented a different plant configuration, allowing Sidon Water to assess how Integro™ could be applied across typical leisure-sector hot water systems.
Phase 2 – Targeted Integro™ Installations
Based on survey findings, Integro™ systems were proposed and installed at selected sites to provide targeted limescale control and support key water system assets.
The installations focus on:
- Protecting calorifiers and hot water cylinders
- Supporting plate heat exchanger performance
- Reducing further scale formation in high-temperature areas
- Supporting reliable hot water recovery
- Helping maintain shower and outlet performance
- Providing a non-salt-based approach to limescale control
Installation points were selected to suit each site’s system layout. Typical locations include incoming cold water supplies, booster set outlets, hot water recirculation returns, and specific domestic hot water circuits serving calorifiers or plate heat exchangers.
At Purley, the proposed strategy included one Integro™ 2 on the cold water main downstream of the booster pump set and one Integro™ 2 on the hot water recirculation return upstream of the plate heat exchanger.
At Cricklewood, the revised installation strategy included cold water supply protection, hot water return protection, and additional protection around the domestic side of the plate heat exchanger circuit to support the heat pump-led hot water system.
Phase 3 – Follow-Up, Review & Verification
The programme includes follow-up inspections and site feedback to review how each installation is performing in day-to-day operation.
Review activity may include:
- Visual inspection of treated pipework and fittings
- Review of showerhead and outlet condition
- Feedback from site maintenance teams
- Inspection of calorifiers, immersion elements or plate heat exchangers where accessible
- Review of hot water performance and recovery observations
- Comparison of site condition before and after installation
For Cricklewood, no formal monitoring has yet taken place. Sidon Water will revisit the site to confirm that the system continues to operate well, with particular attention to its heat pump-led domestic hot water arrangement.
Phase 4 – Sustainability & Energy Performance Opportunities
Several David Lloyd sites include plant configurations where limescale control can support wider sustainability objectives.
Scale formation on heat transfer surfaces can affect how efficiently heat is transferred into domestic hot water. By helping to control scale formation, Integro™ may support improved system efficiency, reduced strain on key components, and more consistent hot water performance over time.
Cricklewood is a particularly useful site for this part of the programme due to its air source heat pump-led hot water system, calorifiers, immersion heaters and plate heat exchangers. The site provides an opportunity to review how limescale control can support long-term hot water resilience in a modern leisure-club plant room.
Any future energy-performance claims should be based on measured data and follow-up review.
Site Summaries
David Lloyd Chigwell
David Lloyd Chigwell was selected as an early proof-of-concept site due to its high water demand and suitability for technical validation. Integro™ was installed to support limescale control across key cold and hot water services, with follow-up review focused on outlet condition, hot water performance and plant protection.
David Lloyd Ringwood
David Lloyd Ringwood provided an opportunity to assess Integro™ in a site where existing softening equipment had been decommissioned. The installation focused on system protection, hot water performance and ongoing support for key plant assets.
David Lloyd Purley
David Lloyd Purley was identified as a strong validation site due to its hard-water conditions, high water demand and clear plant layout. The proposed installation includes protection on both the cold water main and hot water recirculation return, supporting shower performance, plate heat exchanger protection and hot water reliability.

Programme Values
The David Lloyd programme provides a practical, site-led approach to evaluating Integro™ technology across premium leisure environments.
The programme supports:
- Long-term asset protection
- Reliable domestic hot water performance
- Reduced risk of scale-related disruption
- Improved support for shower and outlet condition
- Lower reliance on salt-based treatment approaches
- Practical evidence for future site decisions
- Alignment with operational and sustainability objectives
By working across multiple David Lloyd sites, Sidon Water can assess performance across different system configurations and build a clearer picture of where Integro™ delivers the greatest value.
Next Steps
Sidon Water will continue to support David Lloyd Clubs through follow-up visits, site reviews and performance observations.
Future updates may include:
- Follow-up findings from installed sites
- Additional case studies
- Further photographic evidence
- Energy-performance observations where data is available
- Recommendations for wider estate application
This page will be updated as the programme progresses.
