## Abstract

A rainwater harvesting roof for a water storage tank has a roof of relatively water-impermeable material substantially covering the tank. The roof has a central support supporting the roof, forming a peak, and the roof further has a substantially circumferential band of relatively water-permeable material located in the roof near the outer edge of the roof. The rainwater harvesting roof preferably also has a circumferential gutter of relatively water impermeable material depending downward from the interior surface of the roof and located beneath the substantially circumferential band of relatively water-permeable material. The circumferential gutter further has slits allowing the passage of water therethrough.

## Claims

### Claim 1

A rainwater harvesting roof for a water storage tank; the rainwater harvesting roof comprising:
a roof substantially covering the tank;
a central support supporting the roof;
whereby the roof has a peak at the central support;
the roof further comprising:
a relatively water-impermeable material;
a substantially circumferential band of relatively water-permeable material located in the roof;
the substantially circumferential band of relatively water-permeable material situated lower on the roof than the peak of the roof.

### Claim 2 (depends on 1)

The rainwater harvesting roof of claim 1, where the roof is constructed in gores.

### Claim 3 (depends on 1)

The rainwater harvesting roof of claim 1, where the roof has an outer edge, and where the substantially circumferential band of relatively water-permeable material is located near the outer edge of the roof.

### Claim 4 (depends on 1)

The rainwater harvesting roof of claim 1, where the roof further comprises:
an opening for admitting rainwater in addition to the substantially circumferential band of relatively water-permeable material; the opening further comprising:
an area of relatively water-permeable material.

### Claim 5 (depends on 1)

The rainwater harvesting roof of claim 1, where the roof further comprises:
an interior surface; and,
a circumferential gutter of relatively water-impermeable material depending downward from the interior surface of the roof and located beneath the substantially circumferential band of relatively water-permeable material.

### Claim 7 (depends on 5)

The rainwater harvesting roof of claim 5, where the circumferential gutter further comprises slits allowing the passage of water therethrough.

### Claim 8 (depends on 1)

The rainwater harvesting roof of claim 1, further comprising an access hatch in the roof for manned access to the interior of the tank.

### Claim 9

A rainwater harvesting roof for a water storage tank; the rainwater harvesting roof comprising:
a roof substantially covering the tank;
a central support supporting the roof;
whereby the roof has a peak at the central support;
the roof further comprising:
a relatively water-impermeable material;
a substantially circumferential band of relatively water-permeable material located in the roof near the outer edge of the roof;
the substantially circumferential band of relatively water-permeable material situated lower on the roof than the peak of the roof; and, the roof further comprises:
an outer edge;
an interior surface; and,
a circumferential gutter of relatively water-impermeable material depending downward from the interior surface of the roof and located beneath the substantially circumferential band of relatively water-permeable material; and,
the circumferential gutter further comprises slits allowing the passage of water therethrough.
