    Bengaluru's original sewerage system was built in 1922, a time when the city was much smaller than it is today; the original system served only the heart of the city. In 1950, with the city greatly expanding, a project was initiated to greatly expand the sewerage system. After the Bengaluru Water Supply and Sewerage Board (BWS&SB) was formed in the 1960s, programs were again implemented to expand the system to unsewered areas. Bengaluru‟s growth has been phenomenal. During the last two decades the city of Bengaluru has been experiencing unprecedented growth in the field of Industrial, Commercial and Institutional sectors. This phenomenal growth has resulted in unplanned urban activities surrounding Bengaluru and increase in population and construction activities. As per the census the population of Bengaluru city was 4.08 million in 1991, 5.8 million in 2001, 8.5 million in 2011 and increased to 11.5 million in 2016. This fast growth in population is posing tremendous pressure on infrastructure especially on water supply and underground drainage system. Bengaluru‟s rapid urbanization has also meant growing mountains of waste – solid and liquid. It is estimated that roughly 1,400 MLD of wastewater flows through its three valleys– the Vrishabhavathi , the Koramangala - Challaghatta, and the Hebbal. Sewerage flow in the city follows the regional topography and flow down along the three principal valleys and five minor valleys ensuring free flow of sewerage without any major pumping requirement. BWSSB is now proposed to construct 6 new treatment plants of total capacity of 520 MLD for treating the additional wastewater generated. The total cost of the scheme is Rs.1373.42 Crores. Tender was invited through Government Of Karnataka e-Procurement by the Chief Engineer (WWM), Bengaluru Water Supply and Sewerage Board, Kempegowda Road, Bengaluru-560 009, Karnataka, on behalf of the Chairman, BWSSB, Bengaluru, for the Construction and consultancy services for the Construction of 40 MLD Capacity Sewerage Treatment Plant at Doddabele, Bengaluru during the year 2016-17.
