Terrain Flow Control Outlet
Designed to control rainwater run-off from flat roof areas and podium decks, the Terrain Flow Control Outlet is a 2 part disc which can be installed inside any of our large rainwater outlets to control the flow of rainwater at source on the roof or podium deck, complementing our Rainwater Interception System for roofs and podiums.
The rainwater outlet has 8 positions, which allows a different flow rate on the head of water. The rainwater is attenuated at source within permavoid geocellular cells and released at the designed flow rate.
It should be used in conjunction with the trusted Terrain PVC Soil & Waste and Terrain FUZE drainage pipe products for in-buildings rainwater drainage for a full system approach. For full product details see the Terrain Rainwater Outlets product pages and choose the Flow Control Adjustment Kit to fit inside one of our outlets.
