When you plan on building a publicly accessible swimming pool in Flanders, it's important the swimming pool complies with the Flemish environmental legislation (Vlarem II).
Even public swimming pools that are privately owned, for instance in a hotel or wellness centre, are subject to this legislation. Only swimming pools that are attached to private homes and not open to the public (whether for free, or for a direct or indirect fee) are exempt from this environmental legislation.
his legislation imposes different standards on jacuzzis, indoor and outdoor pools, paddling pools, immersion pools and therapy pools. Water quality (inspections and treatment systems), construction (materials, ventilation, sanitary) and safety (supervision, first aid, fire safety, storage of chemicals) are all strictly and extensively regulated.
