Pumps:

Connecting a pump to your rainwater tank will maximise its uses around the home. There are various sizes of pumps that effectively transfer water, small pumps deigned for hosing cars/garden, medium sized pumps capable of running small irrigation systems with good pressure and large capacity pumps capable of running the entire house and or large irrigation system.

Pump systems:

• Having no pump (limits it applications) relies on gravity to make use of the rainwater in watering cans or drip irrigation.
• Pressure pumps; ranging from small to large capacity pumps providing high flow rates and pressure to facilitate an irrigation system or household applications.
• Submersible pumps can be placed inside tanks as a quieter alternative to stand alone units.

Collection systems:

Roofing, Gutters and Downpipes redirect the rainwater into the tank . Rainwater can be collected from a variety of materials such as ColorbondTM, Zincalume and tin sheeting; polycarbonate or fibreglass sheeting; concrete or terracotta tiles; slate;  Colourbond, copper and stainless steel are commonly used for gutters. PVC or colourbond are used for downpipes and connection to the rainwater tank. Gutters and downpipes must be properly sized with correct fall to achieve the best collection of rainwater.

Asbestos/fibro cement.

Note: Maintek recommend that you replace asbestos roofing when installing a tank. Although it is no longer used in new houses, it may be present in some older roofs (pre 1970s). Asbestos fibres are dangerous to health when inhaled in sufficient quantities; but it is not believed that asbestos in drinking water poses a risk. (NHMRC/ARMCANZ, 1996). Asbestos fibres have been detected in drinking water throughout the world with no known health effects. Also lead from flashings and tar roofs can have adverse effects if consumed.

Roofing Requirements

• A clean roof free from mould, debris and impurities will ensure the collection of uncontaminated rainwater,
• Guttering with appropriate screening, to collect the water from the roof area to the rainwater tank,
• Downpipes take the water from the gutters to the rainwater tank.

Filtration and First Flush Diversion

Filtration

Filters are used to stop unwanted debris getting into the system.Screening devices prevent large particles (such as leaves) entering the rainwater tank. A Rainhead, a metal or plastic frame with a 4-6mm wire mesh leaf screen is typically installed with the downpipe. If there are trees close by leaves can be a real problem.  A leaf screen can be installed along the entire length of the gutter to keep the gutter from clogging and maximizing the rainwater collected.

Types of Filtration

• Stainless steel gutter mesh; Prevents larger items such as leaves from entering the gutter & downpipes
• Leaf eater rainheads collect water and remove leaves from gutters onto ground
• First flush diverter; Diverts the first 8-50 litres of polluted water off the roof into a slow release chamber
• Tank inlet filter; A fine strainer that filters out the smaller particles before the water enters the tank

First flush diverters

A first flush diverter picks up most of the dirt, debris and contaminants (eg; bird/possum droppings, leaves and airborne contaminants from motor vehicles etc, that have collected on the roof between rainfalls) Typically 10 litres for every 100 m2 of roof area is diverted to a slow release chamber. (Equivalent to a 1.6m length of 90mm pipe) As this chamber fills, a plastic ball inside floats to the top sealing off against a seat.This separates the polluted water in the diverter chamber and then directs the clean water to the main part of the rainwater tank. After rain the polluted water slowly drains out of the chamber getting ready for the next rainfall. Occasional this chamber may need to be emptied.

Rainwater Tanks:

Rainwater Tanks aren’t just huge, round and unsightly anymore. They come in many shapes and sizes as well as an extensive range of colours to Match all surrounding paint schemes. Pump connections pressurise the water for uses around the house such as sprinklers, hoses, irrigation etc and for internal uses such as toilets & washers. When planning to install a tank, Roofing and Guttering must be clean or be replaced and appropriate screens should be implemented to stop debris and insects entering the rainwater tank. We recommend an efficient and clean catchment system is in place to get the most out of your rainwater tank.
