A Brief Idea about Rainwater Tank and Harvesting System

There is probably no one who doesn’t like a lush green garden in the backyard, but the Australian climate is not so congenial to create an amazing green landscape. The problem is mostly with the water shortage and people face water restrictions because of limited water supply. People who are very enthusiastic about gardening or professional hobbyists, create rain water tanks in Melbourne to find a way to nurture their creativity.

Collection of Rainwater

You need to plan well about the hard surfaces on your property where rain water sheds such as garage, shed roof and others. So, first calculate the approximate area of the surfaces and calculate how much water you can collect it from those surfaces. Let’s say you have a total of 250 square meters of surface area and Melbourne has average 600mm of rainfall annually. So, multiple both you will get the total litres of water hitting on the surface. You need to minus a certain percentage because of spillage and evaporation; still you can collect quite well for your garden.

Storage of Water

Water is not just needed for plants but for other accessories including water features in Sydney, your small pond, fountain etc. Let’s cut the water features for the time being and focus on the garden including edible if any. As a rule of thumb, 8-10 litres of water is required daily for every square meter fo garden bed, and in summers, for edible trees, you need to pour at least 4-5 liters. If you have a 20 square meter garden and ten fruit trees, you roughly need 230 liters of water every day. So, overall estimation is to create approximately 21000 litres of water for three scorching summer months.

You can create this tank on your terrace, or you can create small tanks hook on your bathroom, kitchen, backyard and other possible places.

Installation Tips

Many people also install garden statues in Melbourne with colourful water features. Apart from manual watering to your plants, you can direct your tank to your water features where the water is circulated continuously.

In brief, you have certain options like:

• Normal guttering or guttering that separates leaves and other debris
• Use first flush diverters to sidetrack the muddy initial flow of water away from the tank.
• Use charged or a wet system that runs through a pipe from roof to tank diverts underground or dry system.
• Also use mesh system to prevent entering mosquitoes or other insects.
