The 8th BANGKOK WATER SUPPLY Improvement Project
Client : The Metropolitan Waterworks Authority (MWA) Administered by : TEAM Consulting Engineering and Management Co., Ltd The MWA is undertaking construction of water supply facilities under the scope of the Eighth Bangkok Water Supply Improvement Project. This addresses the production system; the water transmission system; and the water distribution system. After project implementation, the total water production capacity at the four water treatment plants – Bangkhen, Mahasawat, Samsen and Thonburi – will be upgraded to 6.32 million m³ per day. The main objective is to increase water supply production capacity at the Bangkhen Water Treatment Plant to 400,000 m³ per day and to install additional pumps and related facilities at various pump and distribution stations. Thus, the MWA will be able to extend the water supply service area by another 200 km². The additional capacity will contribute to sufficient water supply capacity up to 2017. TEAM Consulting Engineering and Management Co., Ltd. is engaging in construction supervision and bid evaluation by providing overall guidance for project implementation including pre- and post-qualification of contractors, evaluation of bids, recommendation for contract awards etc.
Metropolitan Water Productivity Enhancement
Client : Metropolitan Waterworks Authority (MWA) Services : Construction Supervision To meet the ever-increasing demand for water supply and water services in Bangkok, Nonthaburi and Samut Prakan, the MWA decided to expand its productivity and transmission tunnel network. TEAM GROUP has been involved in the development of Maha Sawat Water Treatment Plant in Nonthaburi since 1995 and was entrusted, in 2009, with the design of phase 4 and its accompanying transmission conduit. A scheme to increase its productivity was divided into eight phases, each of which was planned to increase daily production capacity by 400,000 cu.m. Upon its completion of phase 4, the plant will be able to produce 1.6 million cu.m./day of water for Bangkok’s Thon Buri side and for Nonthaburi. When all eight phases are finished in 2017, the total production capacity will amount to 3.2 million cu.m./day. TEAM GROUP also supervised the installation of 300 cu.m./minute pump engines at the Pumping Station 3, Bang Khen Water Treatment Plant, a large water plant with a water production capacity of 3.6 million cu.m./day supplying most areas of Bangkok. The installation will enhance the MWA’s water productivity and distribution and help it to meet increasing demand. In the eastern area of Bangkok, we designed and supervised the construction of a 3,200 mm-diameter transmission tunnel from the Highway No. 351 Intersection, running beneath Kanchanaphisek (East portion) Road, to merge with the existing tunnel around Thap Chang Intersection. Water will be distributed through this 13-km long tunnel to those communities which currently rely on groundwater, a cause of land subsidence. The tunnel will also increase water supply for the Lat Krabang and Bang Phli pumping stations and so help to accommodate growth in industrial zones in the vicinity of Suvarnabhumi Airport.
Expansion of Provincial Water Supply, Koh Samui Branch, Phase 1, Part 2
Client : Provincial Waterworks Authority (PWA) Service : Construction Supervision To solve the water supply problem in Koh Samui, the Provincial Waterworks Authority (PWA) decided to expand its provincial water supply service for Koh Samui Branch, Phase 1, Part 2 by installing submarine raw water pipe from Ban Din Daeng Samakkhi, Pak Phraek Sub-district, Don Sak District, Surat Thani Province to Ban Phang Ka in Koh Samui. The project included the installation of high-yield strength steel pipe of 700 mm diameter on Surat Thani main land at the length of 34 km; the installation of submarine PN 10 HDPE pipe of 800 mm diameter at the length of 20 km; and the construction of landfalls of HDPE pipe connecting to the high-yield strength steel pipe at the Phang Ka Bay. The project also covered the design for future connecting points with on-shore pipes, and electrical and controlling systems. TEAM GROUP was assigned as the Project’s construction supervision consultant.
Drainage Tunnel from Saen Saep and Lat Phrao Canals to the Chao Phraya River
Client : IN Joint Venture Co., Ltd. Service : Construction Supervision TEAM GROUP provided quality control services for the construction of the drainage tunnel from Saen Saep and Lat Phrao canals to the Chao Phraya River, by means of which the BMA plans to lessen the ongoing problem of annual flooding in the eastern Bangkok area. This drainage tunnel can rapidly discharge a large volume of flood water and so alleviate flood problems in the 150 km² area of Bang Kapi, Wang Thonglang, Huai Khwang, Din Daeng, Phaya Thai, Saphan Sung, Lat Phrao, Bueng Kum, Khan Na Yao, Lat Krabang and Min Buri. With a total length of 5.11 kilometers, this 5-meter diameter drainage tunnel is at present the longest in Thailand. Starting from the Rama IX swamp and running along Saen Saep Canal, Soi Sukhumvit 71, Sukhumvit Road and Phra Khanong Canal, water is rapidly drained into the Chao Phraya River by the 60 cu.m./second pumping facility installed at the end of the tunnel, which, to avoid impacts on an MRT subway tunnel and on the foundations of surrounding buildings, is at a depth of 27 meters.
