Most cities do not have sewage water tank facilities

Kakinada: National Institute of Hydrology Scientist "G" and Head Dr. Y.R. Satyaji Rao said that most of the cities and town do not have sewage water tank and treatment facilities. National Institute of Hydrology and Ministry of Jal Shakti organised one-day workshop on 'Impact of untreated sewage water on ground water quality and its remedies' at Seminal Hall in Kakinada on Thursday.

Canada Research chair Tier-1, University in Water Security Dr. McBean participated as chief guest on the occasion. Bean said that the main purpose of the workshop is to create awareness on the water pollution. He said that due to the high density of population the density of septic tanks is also increasing. Wherever the groundwater is shallow, the construction of septic tanks should be done with utmost care as per the designs of BIS.

He said that there should not be any type of leakage from the septic tank. The distance between bore well and septic tank should be minimum 5 to 10 meters and it also depends on soil and depth of groundwater levels and quantity of the groundwater.

Satyaji Rao said that if any leakage from septic tanks reaches groundwater, the nitrate contamination will occur and it would lead to health problems. The recommended maximum limit of nitrate by BIS drinking water standard is 45 liter, he said. Scientist T Vijay, Swacha Bharat Mission Consultant Ch. Apparao, United Nation Consultant Ravi Shankar and others were present.
