Pedestrian traffic and splashes of water are common in swimming pools and leisure centres. Floor coverings can also be slippery. To prevent the build up of stagnant water, the floor must slope towards the drainage. For this type of floor a low height inlet gully is needed. An efficient and easy-to-clean drainage system is essential. Swimming pools and leisure centres are designed for people's enjoyment and a slip or fall could spoil any visit, so drainage solutions need to combine both aesthetic and functional requirements. Drainage covers must also be designed to ensure they do no harm to the bare feet of pool and leisure centre users, and eliminate any risk of injury.
