The to pumping stations or Sewage treated waste water is discharged in Treatment Plants via conveyance Mula River. Total area served is about lines. Pumping stations pump the 15 sq. kms. The cost of the project was sewage to Sewage Treatment Rs. 5.69 crores and the plant is Plants where primary & biological functioning since June 2003. secondary treatment is given to 18 MLD sewage water before discharging into any natural water course. Pune Scenario STP The very first sewerage system for Pune city was designed Coarse Screen in1928. The collected sewage was given preliminary treatment At Naidu Hospital Removes large such as screening and grit removal at Bhairoba Nala and it was size garbage used for irrigation purpose by pumping to 17 1/2 Nalli canal area. The plant is located near Naidu This system was designed for 31.8 MLD to cater to the ultimate Hospital. Its present capacity is 90 design capacity for population of 0.26 million in the year 1951. MLD. The sewage generated from the central part of the city is collected In the year 1981, a complete collection and disposal system was at Kasba pumping station & then planned taking into account the adjoining areas where population treated in this STP. The process Pumping Station was expected to increase. A 90 MLD Sewage Treatment Plant used in this plant is activated sludge Collects sewage was constructed at Dr. Naidu I. D. Hospital. The treated sewage is process followed by anaerobic & pumps to STP let off into the Mula-Mutha river. There is an intermediate pumping digestion. The new plant of 115 station at Kasba Peth of 90 MLD capacity from where sewage is MLD is proposed in the same pumped to the sewage treatment plant at Dr. Naidu Hospital. premises . Up to year 1997 the total main sewer length in all of the zones was 90 MLD Inlet Chamber at approximately 146.83 Km, in old Pune city limit. Dr. Naidu STP Sewage Treatment Plant with full-fledged primary & secondary Proposed STP's sewage treatment facility, was treating 90 MLD sewage and Work for 32 MLD STP at Vitthalwadi Bhairoba Nala sewage treatment plant with primary sewage & a 115 MLD STP at Dr. Naidu treatment facility was treating 32 MLD sewage. Hospital is in progress along with their respective pumping stations. Considering the fast growing population of the city additional projects are planned at Mundhawa, Kharadi & Baner, besides the Gravity Main Rising Main existing projects will ultimately have the capacity to treat the total waste water generated in Pune City.

The process Pune City in to the Corporation Limits. The 146 Sq. Km. of area used in this plant is modified activated within old Pune Municipal Corporation limits has increased to 430 sludge process followed by aerobic Sq. Km.. There has been sudden increase of about 40% population digestion. Aeration with the help of load on the available municipal services like water and sanitation. diffusers & settling with the help of Pune Municipal Corporation anticipated this situation prior to the inclined tube settlers are the salient extension of Pune Municipal Corporation Limits and initiated Laboratory features of this plant. The sewage from formulation of the Master Plan up to year 2025 of Water Supply and Erandwana, Kothrud, Warje, Sewerage services for entire 430 Sq. Km. area. After that 15 for daily analyses Karvenagar, Paud Road, Karve Road & quality control villages were excluded from the merger and now the area under the of the process etc. area is treated in this plant. Total area Pune Municipal Corporation’s jurisdiction is around 243 Sq. Kms. served is about 26.15 sq. kms. The cost Due to this, the project report prepared in 1999 was revised in of the project was Rs. 11.12 crores and February 2000. The execution of the master plan for Sewerage the plant is functioning since Dec Project completed in year 2005. 2004. 50 MLD Sludge Total 451 MLD of sewage is generated in Pune Municipal withdrawal Corporation limit, out of that 305 MLD (i.e. 68%) is treated by these Digested sludge STP five plants and the treated effluent is discharged into Mula Mutha ready for use At Bhairoba Nala rivers. as manure To prevent the pollution of the rivers, Pune Municipal Corporation The plant is located at Koregaon park has constructed 4 new sewage treatment plants, along with existing Centrifuge and its capacity is 130 MLD. The treatment plant at Naidu Hospital. For treatment of remaining 146 Digested sludge process used in this plant is activated MLD sewage generated, two treatment plants are proposed. One in is converted into sludge process followed by anaerobic the premises of existing Naidu treatment plant, of 115 MLD dry cake digestion. The gas generated in the capacity & the other at Vitthalwadi near Rajaram Bridge of 32 MLD digester is useful for power generation capacity. The work of these plants is in progress. & the treated water is presently used for irrigation. Sewage generated from Conveyance lines Anaerobic Kondhwa, Vanawadi, Kalyaninagar, For the collection of sewage generated in Pune City conveyance sludge digester Dhanori, Vimannagar, Kalas, lines are laid down along the river and main Nallas for transporting Vishrantwadi and Ghorapadi etc. area the sewage to STP through 300 mm to 1800 mmdia. R.C.C. NP 2 is treated in this plant. Total area served and NP 3 pipelines. 95% work of this project is completed by the is about 82.00 sq. kms. The cost of the year 2005. Total length of laid lines is about 227 Km. 130 MLD project was Rs. 37.50 crores and the plant is functioning since July 2003. Sewage collection For the newly merged villages there was no sewage network to OR convey the waste water, therefore Pune Municipal Corporation has Aerobic STP designed and laid sewerage network in this added area of the Pune sludge digester city to improve Public Sanitation in this area. Total length of sewer lines of the city is about 1500 kms. The diameter varies from 250 At Tanajiwadi mm to 600 mm. The sewage network covers about 95% of the developed area of the newly added villages. The capacity of this plant is of 17 MLD. Two stage biological process is used in this plant, i.e. Bio towers and aeration tank with diffused aeration system. The sewage generated from Model Colony, Shivajinagar, Janwadi, Gokhale Nagar Sludge and Ganesh Khind area is treated in this plant. Total area served is about 18 sq. OR kms. The cost of the project was Rs. 7.43 Extended Aeration Aeration Tank Secondary Clarifier Sludge Thickener crores and the plant is functioning Oxidation of organic matter With defused aeration Activated sludge is withdrawn & Sludge from primary & secondary clarifier treated water proceeds for discharge since April 2004.
