This is my second entry for May (by assuming i was right, i think soooo..). haha Okay, let me share about our trip to KL recently. The trip was held by our beloved storm-water class lecturer.
Oh now everyone must be wondering why a construction management student like me got to do with hydrology class????? That is because, we’re allowed to choose a few free elective classes for every semester (and i try my best to stay away from management related classes except for core subjects, which i cannot run away from it!).
Lets get back to the topic,
We went for the KL-trip from 28th to 30th April with a group of 11 persons (excluded bus drivers hehe). Our accommodation was partially sponsored by one of the group member (we called him Ayah) and the rest we paid. We started off from JB to our first location opposite to Carcosa Seri Negara around 230pm. It was a good experience to come and learn especially when you see the real looks of green roofing, detention pond (where u can see fish inside), rainwater harvesting system, retrofit parking system, garden, bio-retention pond and etc.
The next day, we went to the upstream of Klang River (i forgot the name of that river in fact) and surprisingly the water quality at upstream section was excellent (class 1) but once the water travels to the downstream, the water quality tremendously changed to the colour of teh ais. So, MPS, MPAJ and DBKL planned to treat this problem by implementing a river water treatment plant at a few locations to cater the needs of rejuvenating our Klang River (historically, Klang River wasnt that bad where during that time people can picnic and swims happily). The technology adopted is the first ever river water treatment plant in Malaysia which adopt the latest technology from Japan/Korea (either one, i forgot again because i was distracted by mosquitoes throughout the briefing session in the jungle). This technology encompass three phase which namely are; river cleaning, river treatment and beautification and river development. Each treatment plants were design uniquely according to the conditions and needs. One of them located at Sg Kemensang (if i’m not mistaken, sorry i kept forgetting all the river names haha) consists of 2 types of operating components that plays significant roles for water treatment purpose which are; solar aerated and diffusers. The project is still ongoing and some treatment plants have operates as told.
Next, we continue our trip to SMART tunnel (this place is the one of the should be visited place in Malaysia due to its technology). The system serves as multipurpose tunnel for motorway and storm-water management in KL. As we know, impermeable surfaces in KL are high thus generates higher storm-water runoffs. That’s why KL areas experienced intense flash floods formerly. Currently, the agency is upgrading the system by developing diversion routes for runoffs and flows generated from Sg Gombak tributaries. SMART tunnel operates during storm duration and the system is capable to cater for 3mil cumec water. Therefore, during this storm hour, SMART tunnel will be closed for vehicles.
Actually, i would like to attach some photos but the internet made me wait soooo long. So, ill update this entry with photos next time okay.
