With momentum for sustainable solutions continuing to grow, specifiers must ensure that sustainability is at the heart of every project. One area firmly in focus is water conservation, as the Government introduces targets to address the water scarcity experienced by most UK regions.
Regulators have set legally binding targets to reduce public water use per person, are pushing for greater adoption of smart water metering to manage demand, and have established ambitious leakage reduction targets alongside proposals to strengthen water efficiency within building regulations. Managing water usage efficiently has become essential, both in the context of net-zero ambitions and in the health and wellbeing of vulnerable people.
Pressure Reducing Valves (PRVs) can play a key role. Traditionally specified to improve system performance and longevity, PRVs regulate incoming water pressure to suit the specific requirements of a property. This helps deliver an often-overlooked sustainability benefit: controlling excessive pressure reduces overall water consumption as the UK works towards targets to reduce individual water usage, with an initial reduction of 22 litres/person/day by 2038, with further reductions towards approximately 110 litres by 2050.
Likewise, Government plans and regulators are driving greater adoption of smart water metering to better understand, manage and reduce demand, while identifying inefficiencies in real time. This will create market conditions favouring technologies that manage pressure and consumption at the source, such as PRVs.
DETECTING LEAKS, SAVING WATER
In a time of water scarcity and tightening consumption targets, plumbing systems must work harder to prevent water wastage caused by leaks. One solution is early detection, and the Reliance Valves MultiSafe Leak Detector Control Valve achieves this through continuous monitoring of water consumption, alerting building owners when unusually high volumes of usage are detected.
The MultiSafe Leak Detector monitors water flow rate, pressure, temperature and hardness while also identifying any abnormal usage patterns. As well as monitoring, the isolating valve automatically shuts off the water supply when unusually high usage is detected, and sends the owner an instant alert.
As regulators increasingly expect detailed consumption data to underpin targets and leakage commitments, solutions such as the MultiSafe Leak Detector offer specifiers a practical way of futureproofing projects by complementing smart metering strategies and supporting the data requirements of water companies. For end users, it contributes to water savings, reduced risk of property damage and the peace of mind that this brings.
MANAGING WATER IN MULTI-OCCUPANCY BUILDINGS
When working with multi-occupancy buildings, water efficiency presents a whole new set of challenges due to high demand, shared infrastructure, and the need to balance efficiency with constant, uninterrupted service for residents. The Reliance Valve Tenant Valve Advance addresses these challenges by combining multiple functions into a single, self-contained unit. The one-piece combination valve lets individual apartments have their water pressure managed and consumption monitored independently. A dedicated connection point for installing a water meter supports accurate measurement and billing at a unit level.
Tenant valves are particularly valuable where space and time constraints exist. By integrating all elements of a traditional valve chain into one compact unit, they reduce the number of connection points, in turn simplifying installation, reducing the need for maintenance and speeding up servicing. Fewer connections also mean fewer potential leak points, delivering further water-saving and cost benefits to end users.
These advantages align closely with Government consultations and proposals to strengthen water efficiency within building regulations, including tighter per-person usage expectations and encouragement – or potentially requirements – for efficient fittings. www.johnguest.com/gb/en
