Flooding, water logging, and storm water drainage problems in Hyderabad are deep rooted in historical development that disregarded the natural setting. Problems were aggravated by unplanned expansion of the urban areas and could not be resolved properly because of uncoordinated efforts, in spite of several repeated attempts in the past; all in the absence of a fully integrated urban development plan.

 

Flooding, water logging and storm water drainage problems together with defective water supply, sewerage and solid waste disposal has become more intricate and addressed in isolation led to a vicious cycle. The problem is a lot more complex than realized so far. Incomplete, inefficient storm water drainage chocked by garbage in the absence of proper solid waste disposal system added to flooding and water logging; damaging the under ground water supply and sewerage networks, which resulted in enormous leakages further adding to water logging and rise of water table. The causes can be summarized as:

  • The absence of proper functional storm water drainage system.
  • Leakages from water supply and sewerage system and its associated effect on groundwater table rise in Latifabad and other areas.
  • Absence of effective solid waste disposal system.

The available data indicates that about 21% of the area has ground water table at 0-5 feet below surface, 38% of area has water table in range of 5-10 feet while water table deeper than 10 below surface feet is in eastern and western extremities of the area. Latifabad had been reported to have water table 0-5 feet below surface.

Historically, the groundwater table reported to be 17.50 feet below surface in 1972 suddenly raised up to 7.0 feet below surface in 1973. This was because of leaking of badly damaged sewerage system and sinking of manholes which was later on confirmed by geotechnical investigation in 1977. Actually it is the leakage of water and sewage system which is the main cause of rise in water table.

Of late, the sewerage system in Hyderabad had totally collapsed to the great detriment of the people of Hyderabad who not only faced the menace of choking sewerage lines and overflowing gutters but also suffered from contamination of drinking water by a faulty and leaking sewerage system. There are some generic suggestions to overcome the issue are:

  • All the old and newly constructed drains, main drains or sub-drains, full of settled particles and solid waste must be thoroughly and regularly cleaned and maintained.
  • A proper system of solid waste disposal should be designed and developed.
  • The water supply and sewerage system be improved and leakage be stopped particularly in Latifabad and Rajputana Hospital areas.

To solve this serious issue, a huge expenditure has been made to streamline the entire sewerage system by current District Government. Large dia lines have been laid while the pumping capacity has been enhanced to five times over the previous capacity. Four new sewerage treatement plants are being constructed to eliminate the discharge of untreated sewerage into the canals and Indus River that was a grave health hazard to the downstream communities. Solid waste management system has been improved and mechanized to greater extent. Uninterrupted operation of the pumping stations has been ensured during power failure and standby power Generators of 50 KVA to 1200 KVA capacity have been installed. Now Hyderabad has a much upgraded, safe sewerage system which has greatly improved the health and sanitary conditions in the city.
