This WaterMark Technical Specification sets out requirements for a Sanitary Waste Flushing and Dosing System (SWFDS) that includes a low flush volume Water Closet (WC) pan and matched cistern or flush valve to perform in conjunction with a Sewer Dosing Unit (SDU). The system ensures flushing with minimum discharge volumes aligned to a maximum average full flush volume of 3.0 litres or less and maintain drainage carry by utilising the dosing capability of an in line SDU. This is a performance based specification and provided the test criteria are met then the WC pan and matched cistern or flush valve need not be limited by an upper volume limit.
