Appropriate Catchment Areas for Your Rain Harvesting

The first thing to consider in arranging premium rainwater tanks installation in Adelaide is to select the best catchment area on your roof. This is the area where rain that falls from the sky will collect and rain into your tank. You do not need to collect rain from your entire roof, and in fact there are many features on roofs that make certain areas inappropriate for harvesting. There can be several smaller catchment areas, one large one or it could be your entire roof if it is safe to do so.

Residents will want to gather as much water as possible in order to get the most out of their tank, but it is important that you do not risk harm by determining an irresponsible catchment area. Your catchment area or areas can expand over the roof tops of your home and she or garage. Rain can be collected from most materials; however there are some coatings to look out for. Lead-based paints or bitumen coverings are not suitable for catchment areas. However, virtually everything else, including asbestos is fine. If you are uncertain you can talk to your local tank installation business for some information and opinion. Other materials that should be avoided as a precaution are lead flashing, as well as treated timber.

The roof is often an outlet for a number of pipes and appliances, and these can all produce liquids or materials that can contaminate the rainwater supply. Flue outlets from wood burners and discharge pipes from air conditioning units are just some examples of these things to avoid. Consider best placement carefully when installing these appliances both before and after you have set up your Rainwater tank at Adelaide.
One problem that is easily overcome is that of debris. Low hanging branches over the roof catchment are problematic in that rain that passes through often loosens leaves and twigs and brings them onto the catchment.  The flow of water then washes these pieces either into the gutter or onto the mesh tank guard. In both of these places the debris can cause blockages. The simple solution is to cut back branches far enough so that they are no interfering with the rain harvesting system.

Debris can be blown onto the roof by the wind, as well as dropping from proximal trees. This means that a regular gutter cleaning is necessary to prevent debris even when there are no trees nearby. If you’re not confident or cannot be bothered with this manual process after every storm then it is worth investing in a gutter mesh device that helps debris slide off the roof, leaving the gutters free for water flow.

The next time that you clean your tank out, take a look for excess sludge in the bottom. If this has accumulated significantly it suggests that the problem originates in your gutters. Leaf matter that collects in the damp gutters is the perfect breeding ground for mosquitos, as is the still body of water in your tank. Therefore, in the interest of preventing insect infestation, it is doubly important that you keep your gutters clean and flowing smoothly.

A big cause of excess dust and dirt in the tank is the nature of rain fall. In Australia, we do not receive constant rainfall throughout the year. In fact, in autumn and winter we have patchy rain, and summer is dry as a bone. Imagine how your parched roof would look when the first rains of autumn come. The dust that has built up for an entire season, as well as acidic bird droppings and who knows what else, all mix together with water to form an awful concoction. There is no doubt that this is not the water we want in our tank.

A first flush system cleans the roof just before the next collection to ensure you collect the pure and untainted water you want. If you would like some help in identifying your Ideal Rainwater Tanks Catchment in Adelaide, then visit the Taylor Made Tanks website.
