If you’re in the construction game, then what you need to know when you’re laying your foundations is all about on-site detention tanks. These tanks are for storing refuse; they’re for storing an overflow of water from the site. This is not only a very clever solution to help deal with an unexpected influx of rainwater or flooding, but it’s also mandatory to install in new developments for some councils – you’ll need to check when building in the area with the relevant council to see what the rules are.
Onsite detention tanks store stormwater that’s generated during extended periods of rain, unexpected downpours, and wild storms. This dirty water has the chance to turn into flooding, should the existing drain infrastructure in the street or suburb become full and inundated with water during the surge. Flood waters can cause extensive damage not only to property but to building foundations and infrastructure. This is why adding in additional onsite detention tanks to help accommodate an influx of water is highly desirable when building. You are also able to add onsite detention tanks to existing sites, to enhance their current capabilities.
So, why are these onsite detention tasks so crucial? Well, as you would know from living in Sydney, we experience some of the wildest storms around the country. While northern WA and QLD experience tropical cyclones, we have storms roll across the city any time of year, with varying ferocity. There are plenty of pictures floating around the interest showing these crazy storms come in and over the city. It’s just how the environment is over here. The storms are difficult to predict and do varying amounts of damage. There may be heavy damage and flooding, or we might get away with just a light battering. It really is up to mother nature how these things play out!
However, as fierce as Sydney storms can be, the better equipped each property is to deal with the deluge, the better off everyone will be. With weather protected properties, this ensures that everyone remains as safe as possible and that insurance premiums are kept down too! That’s why onsite detention tanks are mandatory in some areas – it just makes common sense, given the unpredictability of the weather.
The good news is that onsite detention tanks come in a large variety of shapes and sizes. While they are typically below ground tanks, you can get above ground tanks too. These tanks have a range of different shapes from wide, long and deep, to wide, short and deep, so you’re able to fit them onsite no matter what underground space you have to play with – particularly if there is rock beneath the surface of the ground.
For larger properties, you can install multiple different tanks across the property to cover all the different catchment areas. This may prove to be a more effective solution than guiding run off all to the one area on site. If you aren’t sure which is the best option for your property, then make sure to talk with an onsite detention tank specialist to see what they think about your particular situation. You should be able to get a more informed opinion, as they have experience in dealing with these types of problems.
Onsite rainwater detention tanks are not only a clever decision for properties in Sydney, but they are also darn near essential. Consider the cost to clean up after flooding on site (multiple times) and then weigh up the cost of installing an onsite detention tank, and you’ll soon see that it’s a far better solution to install tanks up front.
