STORM WATER MANAGEMENT AND ROAD TUNNEL (SMART)

 SMART stands for Stormwater Management and Road Tunnel. The 13.2m diameter tunnel consists of a 9.7km storm water bypass tunnel, with a 4km dual-deck motorway within the storm water tunnel. The main purpose of SMART is to solve the problem of flash flooding in Kuala Lumpur from the Sungai Klang and Kerayong rivers and also to reduce traffic jams during the daily rush hour.

The dual-purpose SMART tunnel begins at Kampung Berembang Lake and ends at Taman Desa Lake, diverting floodwaters away from the confluence of the two major rivers that run through the center of Kuala Lumpur. The 4km motorway tunnel incorporated into SMART acts as an efficient alternative route from the Southern Gateway of KL-Seremban Highway, Federal Highway, Besraya and East-West Link from entering and exiting the city centre. For motorists, the tunnel greatly reduces the travel time between the Jalan Istana Interchange and Kampung Pandan – from around 15 minutes down to just four minutes.

The SMART tunnel consist of three sections. The upper two sections are roadways that cater to traffic. Each section allows traffic to travel in one direction only. The third section at the bottom is a storm water tunnel. Under normal condition, when there is low rainfall and no storm, the motorway section is open to motorists and the storm water tunnel is closed. During moderate storm, the SMART system is activated and floodwater is diverted into the bypass tunnel in the lower channel of the motorway tunnel. The upper channel is still open to motorists. During an impending flood, the upper two roadways are closed to traffic and evacuated. Then the entire three sections of the SMART tunnel is ready to carry flood waters.

SMART opened to traffic on 14 May 2007, after four years of construction. The cost of the project was around MYR1.887m (approximately $514m). The tunnel handles 30,000 cars per day and has been used 44 times to divert floodwater.

PUTRAJAYA WETLAND

Covering a total area of 335ha, the wetland environment comprises Taman Wetland (138ha) and the wetland areas (197ha). One of the most popular tourist attractions in Putrajaya, the wetlands consist of 24 wetland cells built along the arms of the Chua and Bisa rivers. Marshes and swamps were developed in the cells by transplanting more than 70 species of wetland plants form the Putrajaya Wetland Nursery. Twenty-four species of indigenous fish were later introduced into the wetland cells to enhance their biological diversity.Parks and gardens feature prominently in this Garden City. One of them, the 85ha Botanical Garden at the northern entrance to the Government Precinct, wills thousands of local plants species and an ornamental garden.

In addition, the 62.4 ha. Taman Putra Perdana acts as the urban green lung while the Perdana Walk, 4.7 ha. Linear Park will link Persiaran Perdana with Dataran Putra. Taman Rimba Alam and Taman Jati which are designed to be sustainable recreational forest parks will have nature trails, cycling paths and camping sites. The following are some of the most attractive parks and gardens in Putrajaya. A good starting point to explore Putrajaya Wetlands is to visit Taman Wetland. As the gateway to the wetlands area, Taman Wetland house a Nature Interpretation Centre and a 25 meter high look-out tower which offers a bird's eye view of Putrajaya. Within the park, there are two marked trails with interpretative boards, a flamingo pond, picnic areas and other public amenities.

Taman Wetland is also a wildlife sanctuary, attracting a wide variety of animals to the combined terrestrial-aquatic wetland environment. Several species of local marshland birds and water birds including the Little Egret, the Little Green Heron and Cinnamon Bittern, and migratory birds form Northern Hemisphere have been spotted there. A pair of binoculars will come in handy for bird watching. In the Nature Interpretation Centre, there is a souvenir shop, a wetland diorama, wetland handicraft displays, an AV room and Wetland Café. The Centre, being the focal point for public education on ecotourism, provides information about the wetland plant bed filtration system, conservation of wetland habitats and also focuses on the uses of wetland products.

Putrajaya Wetlands, believed to be the largest constructed freshwater wetlands in the tropics, is the first one of its kind in Malaysia. Where geology, hydrology and biology have created natural wetlands, the Putrajaya Wetland carved out from rubber and oil palm plantations is the result of human ingenuity and technology.

RIVER OF LIFE PUBLIC OUTREACH PROGRAMME (ROL-POP) KLANG RIVER, MALAYSIA

The River of Life (ROL) is currently biggest river rehabilitation project by Malaysia government with aim to improve the water quality of Klang River (river that flow through our capital city of Kuala Lumpur). The ultimate aim is to transform the Sg. Klang into a vibrant and diverse waterfront with high economic value – with the river water quality to be improved to Class IIB by year 2020.

The project is administered by the Performance Management and Delivery Unit (PEMANDU) of the Prime Minister's Department; as part of a Greater Kuala Lumpur / Klang Valley plan under the Ministry of Federal Territory and Urban Wellbeing. In total there are 3 pillars are under ROL: river clean-up, beautification and development.

The River of Life Public Outreach Programme (ROL-POP) is a programme to foster stakeholder partnerships and to improve attitudes and behaviours of target groups to reduce pollution in the Klang River, Malaysia. It is a component of the ROL initiative mooted by the Department of Irrigation and Drainage Malaysia. This section/component is jointly implemented by ERE consult and Global Environment Centre.

The Project site covers the 10km stretch of Klang River representing about 40.4 km2 catchment area (from Klang Gates Dam to the confluence of Sg. Klang and Sg. Ampang. About 80% of the Project site lies within municipality area of Ampang Jaya Municipal Council while the other 20% lies within the municipality area of Kuala Lumpur City Hall. The land use of the Project site is predominantly urban. Residential land use accounts for 38% of the area while commercial and industrial areas account for 7% and 5% respectively. The main tributaries of Sg. Klang within the Project site are Sg. Kemensah, Sg. Sering and Sg. Gisir. The population within the Project site is estimated to be about 146,000.

RAINWATER HARVESTING SYSTEM (RWHS) IN NATIONAL ZOO

NAHRIM has implemented a Rainwater Harvesting System (RWHS) under Tunku Abdul Rahman Lake Restoration Project at the National Zoo in Hulu Selangor, Selangor.

Tunku Abdul Rahman Lake had a problem with water quality where the red algae exist on the lake’s surface. Centre for Water Resources and Climate Change (WRCC) has been given the responsibility to design and build a Rainwater Harvesting System (RWHS) as an alternative water source to replace the water lost due to evaporation and water infiltration process of the lake.

In line with the main objective of rehabilitation project for water quality of Tunku Abdul Rahman Lake, a Rainwater Harvesting System (RWHS) implemented to supply clean water to the lake as an alternative source of water supply to the existing water resources from the contaminated Sungai Pandang. Preliminary study for RWHS design started by estimating the amount of water required and to identify the suitable rooftops for water catchments areas .

This study area is located in the National Zoo located in Ulu Kelang, Selangor. Tunku Abdul Rahman lake has an area of 1.6 hectares with up to 3 m maximum depth. The estimated total volume of water that can be accommodated by the lake is 16,000 m3.

Visitors can find the information written on the mosaic, 'Store 500,000 liters of rainwater (same capacity of 2 Olympic - size swimming pools!).
Installation of a mosaic on the surface of the RWHS tank is intended to provide brief information about rainwater harvesting and rainwater tank size, which is designed to provide additional water for Tunku Abdul Rahman Lake. It can also promote awareness, especially for the children in water conservation and rainwater use.

NAHRIM has been commissioned to conduct a small-scale pilot research project in Paya Indah Wetlands (PIW) in the Focus Group Meeting held in 2013. This study aims to optimize Rainwater Harvesting System (RWHS) for water features to harness the benefit of excess rainwater more efficiently.

A suitable location has been identified for this project, in the area near Tasik Rusiga, which is able to utilize excess runoff from the car park as a catchment area for rainwater, before being channeled into underground water storage tank with the capacity of 250 m3. This water will then be channeled to another similar underground water storage tank after going through the Membrane Water Treatment System. The processed water will be reused as the source for the water features.

Benefits from this study include reducing dependence on treated water, overcoming flash flood problems, reducing pollution into the lakes, maintaining ecosystems and environmental sustainability and promoting recreational activities in PIW. The outcome from this study will also be used in the Masterplan for City Level Rainwater Resources Management especially in the areas that experience flash floods. This study is a pilot project to prepare rainwater resources management plan for urban areas.
