the river; Batu Dam and Klang Gates Dam, which provide water supply to the people of Klang Valley and mitigate floods. Privatisation The maintenance of the Klang River was privatised. Under 30-year concessions, three firms were to manage a river each and ensure cleanliness. Flood control Historically, Kuala Lumpur has often suffered from severe flooding from the river water overflowing the banks. In 1926, a particularly severe flood hit Kuala Lumpur, and work on the river then began in an attempt to reduce the risk of flooding. Part of the Klang River below the Gombak-Klang confluence was straightened, a channel (part of which runs beside the present Jalan Syed Putra) with flood retention banks was dug to divert the river. This project was completed in 1932. Kuala Lumpur Flood Mitigation Efforts in controlling flood water is continuing process. Kuala Lumpur Flood Mitigation is a project to mitigate flash floods affecting Kuala Lumpur. In include diverting flood water from the Gombak River into a few stormwater ponds located in Batu, Jinjang and Kepong. SMART Tunnel The SMART Tunnel (Stormwater Management and Road Tunnel) is part of Kuala Lumpur Flood Mitigation Project and functions to reduce both traffic congestion and flooding. It is a submerged tunnel which can carry both vehicular traffic as well as storm runoff on a lower level. When regular drainage infrastructure is overwhelmed, vehicles are evacuated from the tunnel and the entire tube is used as a gigantic storm drain to prevent Kuala Lumpur from flooding. It diverts water flow from the Kampung Berembang Lake, near the Klang River, to Taman Desa Lake, which is near the Kerayong River (one of the Klang River's tributaries). Water flow can also go the opposite direction, from the Kerayong River to the Klang River. SMART opened in May 2007. Clean up efforts In 2010 Selangor has a stimulus bill that included money to help rehabilitate it. The river's condition has been described as "between critical and bad" by Gareth Jones of Wessex Water, a UK-based company that is participating in the project. Kamal Zaharin, the project mastermind, states that the plans include river cleaning, new source of drinking water, environmental protection, flood mitigation, commercial, tourism and land development activities. Gareth Jones also stated that they plan on tapping groundwater in order to have a source of water that is not the sea. The project has been estimated to require 15 years
