Many People Say To

The next question we get asked is "If it rains so much, then why do we have water restrictions?"Another good question and quite a detailed one.It's a good question. Sure we sometimes have dry winters where we get below average rainfalls but even if you were to receive half of the average rainfall it should be enough to keep your tanks full for most of the year, if not all of it. Melbourne also has a fairly consistent rainfall throughout the year which is great for regularly topping up your tank. Superwall slimline modular rainwater tanks can easily fit down the side of the house or against a wall so you don't lose valuable space. Catchment areas direct water that lands on the soil and directs it towards the dam. With a roof harvest area of 200 square metres you would collect around 80,000 litres. This of course depends on the size of your rainwater tank and how much water you use but providing you have a reasonable size tank you should be right.Many people say to me "Why would I buy a water tank when there is no rain?". This kind of storage does have a lot to do with drought and rainfall. If it doesn't rain again for a while then this process repeats itself. That's why it is important to get water tanks so you can take responsibility for your water usage and take pressure of mains supply. When it does rain then the first rain is soaked up in the soil and does not make it into the dams. The thing is that most true droughts occur inland whereas most of the population lives near the coast where it does rain. Often these catchment areas are further inland where drought and low rainfall is more common than the coast.For example, if you live in Melbourne where water restrictions are amongst the most severe the lowest rainfall in recent years was around 400mm. From this figure we can determine that it is enough water to supply HALF of the average homes' water requirements! One small rainwater tank of around 500 litres can save around 25,000 litres of water per year. Obviously a rainwater tank will not help if there is no rain at all.. These tanks are unique to other tanks because they have a completely flat finish which can be painted or rendered to look just like any normal wall. Meanwhile the water is still being consumed and unless decent rain falls then it will simply run out. To put it simply, most of the water we drink is stored in dams and they are should not be the only source of water available to a city. If it doesn't rain for.
