The present population of Nanded Municipal Corporation is about 4 Lacs and the estimated sewerage discharge will be about 30 MLD, which is three times more than system designed in 1971.

The Manmad- Nizamabad rail line has divided Nanded City into two parts. i.e North Nanded and South Nanded. The south portion is the old city area and all the important government offices are located in this area. This area is thickly populated and heavily congested. Godavari River flows through this area and hence the ground dips from North to south i.e. towards the riverbank.

Area south of Railway line

The south area is in the old part of the city and is thickly populated. The street sewer lines are new but the main sewers A, B, C, D, E which carry sewerage from both the north and the south region are old. The strata is black cotton soil and the maximum depth of sewers is about 26 “ (8 M) below the road level. The main sewers are R.C pipes.

The sewerage load has increased to three times the designed load to 30 MLD and the sewers a re totally inadequate to carry this flow. The sewers are running full and hence the thickness of the sewerage at top is nearly reduced to 30%. Moreover the roadside open drains are also connected to the sewers hence causing the storm water to flow through the sewers, which is far beyond the capacity. As a result the sewers are leaking and the surrounding areas get water logged due to the insufficient drainage/ drying capacity.

Existing open drains along the road are joined to the existing sewerage system thereby damaging the main sewers by clogging choking and overflowing. The intermingled sewer lines and the drainage lines are emptied into the Godavari River thus polluting the River. Approach for maintenance& repairs are difficult as the lines are covered by permanent structure.

Area North of Railway Line

The development in the area is new and better planned with proper roads, educational institutes etc. However only 30 % of the area is covered under the sewerage scheme as the main sewers and street lines are not laid yet. Moreover the sewers are leading to the south area where the sewers cannot carry their load.

The existing houses (70% of the total) are connected to temporary arrangements i.e. septic tanks. It will be necessary to design a new system for 70% of the balance area. The sewerage shall be collected near Data Mandir and directly pumped to the sewerage treatment plant.

Villages under the NWMC:

The villages merged with the NWMC recently do not have the proper infrastructure facilities available. Each village area will have to be studied and provision of an under ground sewerage system or individual septic tanks can be analyzed.

General:

The sewer lines in the area south of Nanded are old and are running to its fullest capacity. The sewers are not accessible at many areas where structures are constructed over the sewer lines. The north area requires new network.

 

Proposed Developments in the Sewerage and Sanitation Sector

 • The entire sewerage system requires to be studied properly in light with the increased population and sewerage load and anticipated growth in future.
 • The existing sewers laid in the south area will not be replaced due to site conditions. Since the street lines in these areas are in working condition, only main sewer lines shall be designed and laid separately.
 • The open drains by the roadside shall be properly built and joined to a new storm water drain to isolate sewerage system.
 • North area sewerage scheme shall be implemented. But the sewerage selection from the north section shall be segregated from the south and pumped separately to sewerage treatment plants.
 • Gurdwara Area requires resurvey of the system and augment the same by laying additional sewer line, constructing manholes/chambers and constructing the new storm water drainage system
 • Temporary sewage disposal system shall be designed and implemented at the temporary accommodation camps.
 • The drains leading to the river shall be trained suitably through box type permanent R.C drains along the river course to avoid pollution.
 • Mobile toilet vans shall be provided at all the major camps.
 • Sulabh Sauchalays for pilgrims shall be constructed at all the camps and city locations.

Sector Focus

The main developments in the sector could be concised as:

 • Laying of new sewers in South portion of Nanded
 • Laying of new sewer mains and in north portion of Nanded
 • New underground sewerage system have to be planned for new villages in NWMC
 • Storm water drains of the city will be rebuilt for training properly towards the river.
 • Treatment of the open drainage to avoid the contamination of the river water.
 • Additional sewerage treatment plant will be constructed.
