In developing countries, like India, the population within sewered areas in prime metros have always been unaware of the importance of underground drainage maintenance. These conduits (sewers) beneath the streets, that can carry away the untreated waste water to the point of treatment and disposal, undoubtedly have done more to improve the quality of life in a community than any other social or technological advance. But since this investment is hidden beneath the ground, it is out of sight and tends to be neglected. It is only when a severe problem arises that people realize drainage maintenance is an important environmental issue which if not attended to, causes widespread diseases, contamination of drinking water and in certain cases, death !. Due to the present awareness levels, the maintenance authorities at the BMC have now discarded the age-old inhuman method of using manual labour for cleaning drains and adopt the more effective ‘preventive’ approach using mechanized methods of sewer cleaning. These methods are in line with practices adopted worldwide.
