Download Drain Cover Flow Rates
Designed to disappear. Supported by practical flow rate guidance. HIDE Drain Covers provide architects, landscape architects, engineers and construction professionals with a refined alternative to traditional drainage grates, delivering seamless integration within premium hardscape finishes. Intended for surface water collection applications, the links to the specification sheets below provide estimated flow-rate information for our 12.5″ and 26″ Drain Covers to assist with preliminary design considerations and product selection.
Effortless elegance enhances your hardscape.
The flow rate through a slot drain is influenced by the slot’s cross-sectional area and the hydraulic conditions, including the slope and roughness of the channel. In this estimation, we utilised standard flow rates for a known slot width and adjusted proportionally based on the given slot dimensions. For precise flow rate determination, it’s recommended to perform detailed hydraulic calculations that account for site-specific parameters or consult a drainage engineer.
The HIDE Drain Cover range is expanding; additional sizes and corresponding flow rate guides will be added to support a broader range of project requirements. Learn more about HIDE Drain Covers
