VO
o BACKGROUND C( Many arrangements are known for collecting rainwater O from roof tops. Generally such arrangements make use of the ci existing guttering and downpipes of a building to direct water flowing into the gutters and into the downpipes to water tanks installed at some level below that of the gutters.
A disadvantage of these systems is that for the collected water to be made available at outlets inside the building, pumps and the ancillary electrical and plumbing installations are required. Pumps are expensive to acquire and install and not infrequently require maintenance or repair.
It is an object of the present invention to address or ameliorate the above disadvantages, or to at least provide a useful alternative.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS First Preferred Embodiment With reference to Figure 1, a roof water collection and delivery system 10 is located on the sloping roof 12 of a building 14. In this instance, the system 10 includes two identical water storage tanks 16 connected together by connector 18 so as to effectively form one storage facility. A feature of the arrangement is that the water storage facility is mounted so that the base of the tank or tanks are above the level of the roof guttering 23 at the edge of the sloping roof 12. System 10 further includes a roof water collector 17.
Preferably, water storage tanks 16 are of a size which is readily manipulated by one installing person. The modular arrangement of interconnecting two or more tanks allows for COMS ID No: ARCS-171656 Received by IP Australia: Time 16:40 Date 2007-12-07 7. Dec. 2007 15:37 WALLINGTON-DUMMER No. 2622 P. 13 11 a convenient manner of providing a desired total storage C(N volume in accordance with roof catchment areas and rainfall C) patterns for example. Storage tanks 16 may be fixed to the roof by fasteners (not shown), for example through flanges 20 provided along edges of the base of the tanks or with ND suitable brackets.

0^ Preferably also, the water storage tanks 16 are located towards the lower edge 22 of the roof 12, so that not only 0 is the catchment area above the roof water collector maximised, but the tanks may be located approximately over the load bearing outer wall 24.
The roof water collector 17 is installed at an intermediate position on the roof between the water storage tank or tanks 16, and the uppermost portion of the roof (not visible in Figure With reference also to Figure 2, in this embodiment, the roof water collector 17 includes a collector manifold 26 and a flexible collector sheet 28 extending from underneath collector manifold 26. The roof water collector 17 is located "upstream" of the storage tanks 16, at a point where the uppermost point of the storage tanks is at least just below the level the collector manifold 26.
Collector manifold 26 is provided with perforations or slots 30 arranged along the length of the manifold, and COMS ID No: ARCS-171656 Received by IP Australia: Time 16:40 Date 2007-12-07 71.

Collector d manifold 26 is also fixed to the roof by suitable brackets (not shown). It will be understood that although the collector manifold has been illustrated as a tubular IO element, any at least partially enclosed channel, blocked
\O
o off at both ends and able to receive water from the roof (C water collector, and conduct that water to an outlet, may o form a water collecting manifold. Likewise the water entry
(N
into the manifold need not be a series of slots as illustrated in Figure 2 but may be of any other suitable configuration. Thus for example the collector manifold may have a profile as shown in the inset of Figure 2A. In this arrangement the collector manifold is roll-formed to include a bottom portion 31 and one side portion 32 rising from the lower edge of the bottom portion 31. A top portion 33 extends over the bottom portion and a front portion 34 extends downwards towards the bottom, leaving a gap to form a continuous opening 36 along its lower edge at the junction with the lower edge of the flexible collector sheet 28.
Flexible collector sheet 28 is the same length as collector manifold 26 and is adapted to conform along its upper edge 38 with the contours of the roof to which the system is installed. Collector sheet 28 acts to intercept COMS ID No: ARCS-171656 Received by IP Australia: Time 16:40 Date 2007-12-07 7.

In the example CA' shown in Figure 1, the upper edge 38 may be inserted between the overlapping edges of the row of upward tiles "upstream" of the collector sheet 28 and the next lower row of tiles 41.
VO
VO The flexibility of the collector sheet 28 allows it to Sconform also to other roof profiles such as corrugated iron ci and other metal profile roofing materials. In the case of 0 continuous metal sheeted roof surfaces, the upper edge 38 of the sheet 28 is worked into the troughs and fixed in place with a suitable adhesive.
Although in the illustration of Figure 1, the roof water collector is shown as being in one piece, it will be understood that roof water collectors may also be provided in relatively short lengths and linked together in similar manner to the storage tanks 16.
At least one end of the collector manifold 26 (or a line of interconnected manifolds) is connected by a water conducting conduit 42 to an inlet 44 of at least one of the water storage tanks 16.
Where needed, a leaf deflecting mesh 27 may extend from proximate the upper edge 38 of collector sheet 28 to the top of the collector manifold 26.

Third Preferred Embodiment In a third preferred embodiment of the present invention, with reference to Figure 4, a roof water collector 54 may be located in the valley 56 of a roof 12; that is, within the channel provided at the junction of two sloping roof surfaces 12A and 12B.
COMS ID No: ARCS-171656 Received by IP Australia: Time 16:40 Date 2007-12-07 7, Dec. 2007 15:37 WALLINGTON-DUMMER No. 2622 P. 17 15 In this embodiment, one or more water storage tanks 16 as 0- previously described, may be installed in the vicinity of q0 the roof valley 56 as shown in Figure 4.
o Typically, especially on a tiled roof, the valley channel 58 lies at a level somewhat below the tile surfaces. The
O
\I0 water collector 54 in this embodiment is a fabricated 0 trough forming a base and end portions so as to fit in the valley channel 58. Water flowing off the adjoining roof o surfaces enters the water collector 54. Preferably, water collector 54 is provided with a mesh cover 60 to prevent leaves and other detritus from entering the water collector 54. The lowermost end portion 62 of the water collector trough is provided with an outlet to which a water conduction conduit 42 connects the water collector 54 with the nearest of the water storage tanks 16.
In each of the above described embodiments, an outlet fitting 45 of the water storage tank 16 (or of one of the interconnected storage tanks) is connected to a water distribution pipe 47 leading to one or more water outlets within the building as best seen in Figure 3. Stored water may be used for a variety of uses; for example flushing toilets, or with suitable filtering provide a source of clean drinking water.

0Fourth Preferred Embodiment ci In a fourth preferred embodiment of the invention, with reference to Figures 5 to 7, one or more storage tanks 116 are again adapted for mounting to the surface of a sloping roof 112 of a building 114. In this instance however, each tank 116 is itself adapted to act as the water collector.
As best seen in the side elevation view of Figure 5, a storage tank 116 is provided with generally triangular shaped sides 115 tapering from the rear wall 117 of the tank to a collection front wall 119. As can be seen in Figures 6 and 7, front wall 119 of the tank is perforated, for example with slots 121. A flexible collector sheet 128 extends from the lower edge of front wall 119 and, as described above, is made to conform to the configuration of the roof surface.
Front wall 119 is of sufficient height to intercept water flowing down the surface of sloping roof 112 and allow water to enter the tank 116. The top 123 of tank 116 is COMS ID No: ARCS-171656 Received by IP Australia: Time 16:40 Date 2007-12-07 7.
