Lucknow City lacks in proper drainage system; City frequently faces urban flooding
Drainage systems are the major source of conducting waste water and also rain water. But, due to sedimentation, siltation and poor management, these systems fail. Therefore, in the monsoon period, drainage system overflows and the surrounding areas become flooded. The severe flooding in Lucknow city is believed to originate from insufficient drainage capacity and blockages of the drainage system due to huge volumes of garbage and polyethylene bags. Out of the 28 drains about 20 drains are choked and silted. Many of old drains and waterbodies have been turned into urbanized area. All these factors trigger the problem of flooding in the city.
The severe flooding in monsoon period in Lucknow city is believed to originate from insufficient drainage capacity and blockages of the drainage system due to huge volumes of garbage and polyethylene bags. Inadequate maintenance of existing natural and man-made drains due to lack of comprehensive and planned maintenance program, equipments, adequate budget, staffing, proper monitoring program and institutional set up to effectively operate and maintain the drainage network. Poor solid waste management is the main problem to maintain the rain water drainage. Drainage systems turn into most unpleasant condition when many other factors correlate with it. These factors are categorised as follows-
Improper Drainage System with low-lying topography
Blockage in Canal System
Blockage in existing drainage system
No drainage system
Open field and no drainage system, and disposal of wastage
Overflow in the Nala
Railway bridge underpass area with no drainage
The first sewerage network was established in different parts of the city over a century ago. The network has not been augmented from time to time to keep in pace with development of the city. About 70-80% of population in old-Lucknow is covered by sewer lines, but a major portion of it is choked and virtually broken, leading over flow of sewage into storm water drains.
