AQUARIUS – Where Smart Water Data Meets the SMART Tunnel

There has been a lot of talk recently about the difference between “smart data” and big data.

Big data involves collecting copious amounts of information; smart data involves processing the data collected to create actionable data that empowers decisions. When it comes to water, the Aquatics Informatics AQUARIUS suite is the mission-critical software trusted by hundreds of customers around the world to turn big data into smart data.

Let’s travel to Malaysia, where smart data meets the SMART Tunnel.

The “Stormwater Management And Road Tunnel” (SMART Tunnel), has been featured in many news stories and television shows such as Extreme Engineering on the Discovery Channel, Build It Bigger on the Science Channel, Megastructures on the National Geographic Channel, and Man Made Marvels on the Science Channel. The reason the Kuala Lumpur tunnel is so amazing starts with its length: it is the second longest storm drainage tunnel in Asia at 9.7 km (6.0 mi). The truly amazing aspect of the SMART tunnel is that it’s the first dual-use storm drainage and road structure in the world. The tunnel is mainly used to ease traffic congestion in Kuala Lumpur, but there is a storm drainage system under the two decks of cars. Essentially, the tunnel acts as a reservoir to decrease the peak of water flows of the Klang river and therefore mitigate the severity of floods. However, that’s not all. In the event of a bad flood, the road decks can also be used to drain the storm water away from the city. That’s right. The car levels can be completely filled with water as well!

If that sounds complicated, it’s because it is extremely complicated.

How do you manage the road traffic and the water drainage for this .5 Billion dollar project? The answer is real-time water time series stored and analysed using Aquatic Informatics AQUARIUS Time-Series and modelled in AQUARIUS Forecast.

Since 2012, the SMART Stormwater Control Center has used AQUARIUS for processing, storing, and building simulations of environmental data. AQUARIUS Time-Series collects data from 28 river flow and rainfall sites. This data is modelled in AQUARIUS Forecast to forecast two hours ahead. Once the models indicate that a flood will occur, notifications trigger audio alarms and other types of updates at 20 operational sites. The decision to close the tunnel is, of course, then made by a manager and Kuala Lumpur is protected from Klang river floods.

Another interesting aspect of this engineering triumph is that the tunnel can also be filled while there are cars still inside; a section of the tunnel is blocked off and the cars can still be leaving as the water enters the opposite end.

The SMART Tunnel is an excellent example of the exciting projects AQUARIUS customers are launching around the world.

“The SMART (Stormwater Management and Road Tunnel) Tunnel stretches 9.7 km beneath Malaysia’s capital. TBM technology was employed in the construction of this dual purpose tunnel, which supports the transportation infrastructure of Kuala Lumpur with a double-deck road and functions as a stormwater line during times of heavy rain when the Klang river floods downtown Kuala Lumpur, diverting the flood water into a basin away from the city. The construction began in 2003 and the tunnel was opened to service in 2007.”
