Technical Site Visit (14th September 2017, Half Day Tour)

Proposed Tour Venues

1. Stormwater Management and Road Tunnel (SMART)

The Stormwater Management And Road Tunnel (SMART Tunnel), E38, is a storm drainage and road structure in Kuala Lumpur, Malaysia, and a major national project in the country. The 9.7 km (6.0 mi) tunnel is the longest stormwater tunnel in South East Asia and second longest in Asia.

The main objective of this tunnel is to solve the problem of flash floods in Kuala Lumpur and also to reduce traffic jams along Jalan Sungai Besi and Loke Yew flyover at Pudu during rush hour. There are two components of this tunnel, the stormwater tunnel and motorway tunnel. It is the longest multi-purpose tunnel in the world.

In 2011, the SMART tunnel received the UN Habitat Scroll of Honour Award for its innovative and unique management of storm water and peak hour traffic.

Stormwater tunnel

  • Construction cost: RM1,887 million (US$514.6 million)
  • Stormwater tunnel length: 9.7 km (6.0 mi)
  • Diameter: 13.2 m (43.3 ft) (outer diameter)
  • Tunnelling method: Tunnel Boring Machine (TBM)
  • TBM type: Slurry shield

2. Pantai 2 Sewage Treatment Plant

The Pantai Catchment is the largest of eight catchments within the city of Kuala Lumpur. The catchment covers an area of over 6,700 ha, which include the central and south-western parts of Kuala Lumpur.

Within the Pantai catchment are Bandar Baru Sentul, the proposed Sentul Raya Development, Central Business District, and popular recreational areas such as Bukit Kiara and Botanical Gardens.

The existing Pantai CSTP consists of large Aerated lagoons and recently constructed mechanize plant (which are separated by the New Pantai Expressway, NPE) has a total capacity for 877,000 PE, whereas the Pantai CSTP is presently serving a connected PE of 1.18 million. Thus, the Pantai CSTP is highly overloaded and has to be upgraded immediately. The new STP (Pantai 2 STP) is to be constructed at an ultimate capacity of 1.423 million PE.

It is proposed that the large aerated lagoons to be upgraded to a mechanized Pantai 2 STP to alleviate the current situation. The new centralized waste water treatment facility will generate standard A effluent in accordance with the Environmental Quality (Sewage) Regulation 2009.

A compact treatment facility using Advanced A2O process together with sludge treatment and dewatering facilities will be constructed. This is to replace the existing aerated lagoons, which will incorporate anaerobic digestion with solid dewatering.

A 1.423 million PE sludge management facility will be constructed to treat and manage the waste biological sludge, with the provision of bio gas power generation facility.

The Pantai 2 STP will be developed as an underground facility with ground/area above the STP developed as a leisure park with sports, recreational, administration building and community facilities for the local residents.

3. Sungai Selangor Phase 2 (SSP 2) WTP

Washwater Recovery Tanks & Sludge Pumphouse, Sg. Selangor Phase 2 The second concession, a Construction Cum Operation Agreement (CCOA) was awarded on 22 March 1995 to finance, design, construct, operate, manage and maintain a new 950 MLD WTP at Bukit Badongunder the Selangor State Government’s “Sg. Selangor Water Supply Scheme Phase 2 Project” (SSP2).

This mammoth project cost at the total of RM1.2 billion (USD 0.33 billion) and was developed in two (2) stages.

  • The Stage 1 of the Project with a capacity of 475 MLD was commissioned in July 1998, five (5) months ahead of its original schedule during the height of the water crisis that hit Selangor and Kuala Lumpur.
  • The Stage 2 of the Works for another 475 MLD was completed on 31 December 2000 – one year ahead of original schedule.

4. 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 there 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 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, a 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.

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.

5. Hartalega NGC Sdn Bhd

Hartalega started as a single-line operation back in 1988, and now have evolved to a company that has singlehandedly revolutionised glove-making. It bacame the inventor of the world’s first lightweight Nitrile glove in 2005, which caused a demand shift from latex to nitrile gloves all over the globe. Needless to say, Hartalega are now the largest producer of nitrile gloves in the world, capable of manufacturing 27 billion gloves a year and will progressively expand to 42 billion gloves in 2020.

Yet all this would not have been possible without our deep-rooted commitment towards innovation, which has incepted advanced, proprietary manufacturing technologies that is unrivalled to this day.

Hartalega’s continued technological innovations help ensure our gloves are manufactured with equal emphasis on efficiency and quality; a key reason why we are trusted as the OEM manufacturer for some of the world’s biggest brands.

The purpose of the visit is to learn more about the management of water supply, the use of ground water, water recycling, wastewater treatment, water consumption, etc. and to have a first-hand view of the equipment used and technologies involved.
