The region attracts people from around the world, offering a diverse economy and a high quality of life. These natural areas clean the air, provide drinking water, provide diverse flora and fauna habitats, including pollinators, and they provide opportunities for recreational activities that benefit public health and overall quality of life.

Rainwater tanks can impact adversely on human health in two main ways: Pathogens such as Cryptosporidium and Giardia may be present in rainwater, and in urban areas, lead and other compounds pose a risk of chemical contamination.

The absence of fluoride in rainwater should also be considered for children in the household. Prevent mosquito breeding in the tank To avoid creating a mosquito breeding habitat, ensure tank inlets and overflows are properly screened to exclude mosquitoes. Drinking rainwater If your rainwater is to be used for human consumption, the system must be designed, operated and maintained to ensure the water quality is suitable.

Disinfecting the water before consumption should still be considered for those whose immune system is compromised.

Backflow prevention If rainwater and mains water are interconnected such as for back-upthe mains water must be isolated from the rainwater system by a suitable backflow prevention device or a visible air gap, as required by the Plumbing Code of Australia.

Most mains switchover devices already incorporate backflow prevention suitable for use with an above-ground tank. If mains water is interconnected with rainwater from an underground tank, a testable backflow prevention device must be fitted on the mains water supply to the house.

It normally needs to be tested annually. Rainwater harvesting system checklists Use these lists to guide the design of a rainwater system suitable for your property and planned rainwater uses. A rainwater harvesting system has the following components: The components of a rainwater harvesting system.

The pipe can go down, often underground, and then up again, usually at the tank. In a charged line rainwater system the water is pushed into the tank by water pressure in the pipe.

Roof and gutters Rainwater can be collected from most roof types, depending on the quality of rainwater required. For garden or lawn irrigation: For all other uses, also: For drinking water, also avoid collecting rainwater: Leaf-shedding rain-heads If no leaf screen is fitted to gutters, fit leaf-shedding rain-heads to the downpipes.

These devices employ a sloping screen to intercept leaves and reduce excessive leaf build-up in first flush diverters and tank inlet strainer baskets.

They are essential if the tank has no inlet strainer e. Install the rain-heads higher than the tank inlet but at a height that can be easily accessed for maintenance.

John Caley Ecological Design Gutter leaf screens keep leaves out of the rainwater collection system. John Caley Ecological Design Leaf-shedding rain-heads intercept leaves and reduce excessive leaf build-up. First flush diverters The first rain after a dry spell washes some of the accumulated dust and bird droppings off your roof and into your rainwater tank, accumulating as sediment in the bottom of the tank and lessening the quality of the water.

First flush diverters intercept the first roof runoff and prevent it from entering your rainwater tank, in one of two main ways: First flush diverters are typically sized to divert about 10L per 50m2 of roof plan area. A diverter may be required by local government regulation.

First flush diverters should be installed for all drinking water systems and are beneficial for systems supplying other internal uses. For garden irrigation supply, their main benefit would be the reduced need for desludging the tank. Installation details include ensuring: Rainwater tanks Choose a rainwater tank that suits your needs.

Tank size When deciding the best size for your tank consider: Approximate tank sizes for a four person household with mains water and evenly spread rainfall Use Toilet flushing and use on a small garden 2,—3, Toilet flushing, clothes washing and small garden 3,—5, Whole of house water supply 5,—20, Where average rainfall is highly seasonal or no mains water is available, much larger tanks are typically required.

Use the Alternative Technology Association Tankulator at http: Tank materials Common tank materials include polyethylene, fibreglass, concrete and steel.

Steel tanks are strong and can be made to a custom size.

Smaller tanks are prefabricated; tanks over 30kL are usually assembled on site. Prefabricated steel tanks are usually coated internally and under the base with a polymer film to prevent corrosion. The polymer lining commonly used in Australia should be protected from direct sunlight as it is not UV stabilised.

Suppliers generally require steel tanks to be installed on a concrete slab, pavers or a stand. Plastic tanks are durable, relatively lightweight and relatively inexpensive.San Francisco Health Code ARTICLE 12C: ALTERNATE WATER SOURCES FOR NON-POTABLE APPLICATIONS Sec.
