BS EN 1253 discusses gullies for buildings. BS EN 1253-5 is the fifth part of BS EN 1253 multi-series and discusses gullies with light liquids closure. Light liquid closures for buildings are applied to avoid uncontrolled discharge of light liquids into drainage systems in case of an emergency.
BS EN 1253-5 specifies requirements for the design, construction, performance, application, and marking as well as test methods of factory-made gullies with a light liquid closure for buildings.
Note: BS EN 1253-5 does not apply to installations for separation of light liquids covered by EN 858-1.
BS EN 1253-5 on gullies for buildings is useful for:
A gulley is a fitting with a chamber that is designed to collect rainwater, wastewater, and groundwater, conveying it to an underground surface-water sewer. Gullies can be used to drain wastewater and rainfall from buildings, large, paved areas and roadsides, pedestrian areas, parking areas, pavements, roofs, and so on.
BS EN 1253-5 provides you with the necessary guidance on requirements for the design, construction, performance, application, and marking as well as test methods of factory-made gullies with a light liquid closure for buildings. BS EN 1253-5 helps to manufacture high-quality gulley.
