English Definition

Plumbing fixtures โ€” taps, showers, toilets, and urinals โ€” engineered to deliver equivalent function at significantly reduced water flow rates, achieving 30โ€“50% water savings over standard products and forming the primary strategy for indoor water efficiency in UAE green buildings.

What Are Low Flow Fixtures?

Low flow fixtures are plumbing and sanitary fittings designed to perform their intended function โ€” washing, flushing, showering โ€” while consuming significantly less water than conventional equivalents. They achieve this through a combination of flow restrictors, aerators (which mix air into the water stream to maintain perceived pressure and coverage at lower flow rates), optimised hydraulic design, and โ€” in the case of toilets โ€” improved flush valve and cistern engineering.

Main Fixture Types and Flow Rates

The principal low flow fixture types and their target flow rates in UAE green buildings are as follows. Basin taps: standard taps flow at 8โ€“12 litres per minute (L/min); low-flow aerators reduce this to 4โ€“6 L/min or less, with sensor-operated taps providing additional savings by eliminating water waste during soaping and rinsing. Showerheads: standard showerheads flow at 10โ€“15 L/min; low-flow models achieve 6โ€“8 L/min using pressurisation and aerator technology. Toilets: the single largest indoor water consumer in most buildings; dual-flush WCs offering a 4.5-litre half-flush and 6-litre full-flush replace older single-flush 9-litre cisterns. Urinals: sensor-controlled flush urinals and waterless urinals โ€” widely adopted in UAE commercial buildings โ€” can reduce urinal water consumption by 50โ€“100% compared to timed-flush systems.

UAE Regulatory Requirements and Green Building Credits

The Dubai Green Building Regulations specify maximum flow rates for each fixture type as a mandatory compliance requirement. Under Al Sa’fat, buildings earn water efficiency credits by demonstrating that the specified fixtures achieve a percentage reduction in annual water consumption below the Al Sa’fat baseline โ€” calculated using a standardised methodology based on occupancy numbers, fixture types, and flow rates. The percentage reduction determines the number of credits awarded, with higher reductions earning more points toward the overall star rating.

Under LEED WE (Water Efficiency), a similar baseline comparison methodology is used, referencing the US EPA WaterSense programme benchmarks for fixture flow rates. Products bearing the WaterSense label are certified to use at least 20% less water than standard products while meeting performance requirements โ€” and are widely available in the UAE through major plumbing suppliers. Commissioning of plumbing systems โ€” verifying that specified flow rates are achieved in practice โ€” is an important step to ensure that design-stage water efficiency calculations are realised in operation.
