A tray (10) for use in a green roof system has a floor (12) and four sides (14) and is moulded from a plastics material. At the centre of, and towards the base of each side wall, there is a circular hole/orifice (20) for use in connecting the interior of one tray with an adjacent tray. The trays may be connected together using male (24) and female (30) connectors and used particularly on roofs for temporary (or more permanent water storage and as a planting box for a green roof. The trays (10) may be linked together by fluid flow connectors (50) which include a short length of piping/tubing linking the holes of adjacent trays for fluid flow between trays. Connectors which block passage of fluid between two adjacent trays are also provided. A further connector which has a partial passage including a dam wall is also provided. The trays (10) can be connected to form a reservoir on the roof of a building with the connectors being used to control the flow of water e.g blocking the passage of water on downhill slopes.
A modular green roof system comprising a tray having a base, side walls and connecting means for connecting the tray in a side by side array with a second, substantially identical, tray, the side walls of the tray defining an aperture to allow fluid to flow from or into the tray wherein the side walls of the tray are connectable together by male and female connectors defined on top of the side walls of the tray in which arrangement the apertures of the connected trays are opposed and separated by a gap and the trays are, at least loosely, linked together;
A tray for use in a green roof system having a base, side walls and connecting means for connecting the trays in a side by side array with a second, substantially identical tray, the side walls defining an aperture to allow fluid to flow from or into the tray, wherein the side walls of the tray are connectable together by male and female connectors defined on the side walls of the tray by means of which connectors, the trays may be, at least loosely, linked together, in which arrangement the apertures of the connected trays are opposed and separated by a gap and wherein the gap is configured to receive a fluid flow connector which can be slid between the apertures and which defines a tubular portion connecting the apertures together allowing the passage of fluid from one tray to the connected tray.
