Dhaka WASA signs a contract with TEDAGUA to upgrade the drinking water systems in the Minpur area

The joint venture formed by Cobra Instalaciones y Servicios and TEDAGUA has been awarded the contract for the rehabilitation of the water conduits with the DWASA (Dhaka Water Supply & Sewerage Authority) in Dhaka, the capital of Bangladesh and the most densely populated city in the world. This project forms part of the comprehensive overhaul and upgrade of the existing network in the Bengali capital.

The ceremony for the signing of the contract was presided by the General Manager of DWASA, Engr. Taqsem A Kahn and was held on 27 September, with the Honourable Secretary of LGD Mr. Abu Alam Mohammad Shahid Khan, the Spanish Ambassador in Dhaka Mr. Luis Tejada Chacon and the Chairman of the Board of DWASA, Mr. Rahmatullah, in attendance.

With an estimated completion time of 28 months, the project will improve the drinking water supply in 10 districts of the Mirpur zone, to the northeast of the Dhaka. The project has a budget of 32.3 million USD (approximately 24.2 million euros) and will be financed by the World Bank and the Asian Development Bank.

The project consists of the preparation of the construction and execution project for a total of 509 km of pipes with diameters ranging from 90 to 600 mm made of high-density polyethylene (348 km) and PVC (161 km), with more than 2,100 valves to be installed throughout the network. Although most of these conduits will be installed in trenches, 161 km will be installed using “trenchless” methods: 127 km with the pipe bursting system, and 34 km using horizontal directional drilling. In addition, 49 wells that supply the capital will be upgraded and modernized and some 35,000 homes will be connected to the supply network. These actions will guarantee the drinking water supply for an estimated population of 350,000 inhabitants.

Tedagua plans to maintain a technical office with more than 35 workers on staff and estimates that the total labour for the project will exceed 450 workers.
