'Sewerage system of the city is very poor. The city as a whole does not have a sewerage system. Wherever exists, it is not an exclusive sewerage system. It is a combined waste water and storm water collection system. The collection system is neither complete nor efficient. It exists only in the central core of Allahabad city.'
These are the findings of Feedback Ventures given recently in its draft related to city's development under Jawahar Nehru Urban Renewal Mission.
Referring to the present scenario of sewerage and sanitation condition the draft states that most of the existing sewers are old brick sewers which have outlived their life and design as well. The structural condition of sewers in most stretches is poor. Hydraulic capacities are insufficient even for the present flows. All existing lines have heavy silt depositions and sewers are severely choked due to ingress of solid waste.
"All sewer lines have large variations in slopes. Due to inadequacies of the existing system, as described above, most of the city's waste water ends up in surface drains which carry it to Ganga and Yamuna rivers" said the report.
It further states that unlined drains are found choked by garbage and solid wastes like polythene, papers, wrappers etc. Waste water flowing through the unlined drains is producing foul smell in the city due to putrefaction of the organic matter and is polluting the environment. Since the waste water remains stagnant in the drains for 24 hours, it is good place for breading of mosquitoes, flies and harmful bacteria and viruses. This may cause unhygienic condition to the extent of epidemic in the city. Condition of the existing system is also poor.

{{/usCountry}}It notes that during the reconnaissance survey of the city, most of the sewerage system was found choked by silt and garbage.
Solid materials lying in the sewerage lines restrict the flow. Cleaning and maintenance of sewer lines is not proper. Due to silting of the solids in the line, the carrying capacity gets drastically reduced and there develop chances of overflow during the peak flows due to reduced section and carrying capacity of the system. During the rainy season, situation in certain areas becomes serious for these get flooded, said the report.
NN administrator Amrit Abhijat has invited suggestions from public in this regard.
