The water supply schemes in
Nanded are functioning since 1936, which was further augmented
with supplementary scheme in 1969. The scheme was designed for
the population of 2.7 lakh by 1991. Further improvement to
Nanded Water Supply Scheme was executed and commissioned in 1997
for additional capacity of 60 MLD. Presently the water is lifted
from Godavari river and supplied through ten various reservoirs.

Nanded Distribution System
and 6 Villages Water Supply Scheme at an estimated cost of
Rs.58.40 crores was sanctioned by the Government to
be implemented in 4 stages. The 6 villages included some
of the peri urban areas of Nanded not forming part of
NWCMC.
-
The project component included
-Construction of 13 RCC ESRs
-Construction of 2 MBRs
-Rising Main of 4.2kms, Gravity Main of 14.25kms, and
distribution system of 164.10 kms .The scheme was designed
for water supply at the 135ltrs /pcd for urban population
and 100ltrs /pcd for rural population. Status of the scheme
is as under:
-
Stage I (Rs8.62 cr)
proposed to cover three villages Taroda (Bk), Taroda(Kd)
and Jangamwadi (NWCMC) areas. It included establishing a
transmission line of 3.75 kms (Main and Gravity lines)
from Kabra nagar WTP to Taroda Naka, MBR at Taroda naka
and distribution system of 30.57 kms, Pump House including
pumping machineries at Kabra Nagar.
-
Stage II (Rs.12.64 cr)
covered the Nanded City area. This include establishing
Rising main of 1.4 kms . Construction of ESR at Sundar
Nagar, Degaon Chawl and Fort, distribution system of 37.33
kms and repairs and replacement of Pumping machineries.
Status of work: The project is partly completed as
distribution network of 18.33 kms is yet to be finished
and ESR work at Degaon and Fort is still in progress.
-
Stage III ( Rs. 17.51
cr) : This proposed to establish Transmission lines of
6.25 kms, MBR of 20 lakh liters, ESR of 15 lakh and 20
lakh liters at Nandigram and Sneh Nagar and distribution
system of 24 kms. This stage yet to commence
-
Stage IV : (Rs.19.63
Cr)- The project component include additional
distribution system for Taroda (Bk) and Taroda(Kd). This
part of the scheme is recently sanctioned by the Govt and
the implementation is pending.

Godavari river is the major water supply to the Nanded
City. NWCMC currently draws majority of its water from the
Vishnupuri Dam located in the periphery of the city limits and
about 9 km from the city center. Apart from this, it pumps
water from the Godavari river in the city through Jack wells dug
on the banks of the river Godavari at the New Pump House. The
Corporation has about 91 bore wells at different locations in
the city to service local populace in specific pockets.
The Vishnupuri Dam is essentially
an irrigation facility, which services a vast rural area through
a lift irrigation scheme, apart from supplying water for
drinking purposes to NWCMC and other rural and urban
settlements.
The following table presents a
summary of the sources of water and the quantities currently
being drawn from them.

While the total quantity allocated to NWCMC from the
Vishnupuri dam and the river Godavari is about 60 MLD, the total
quantity of water drawn from various sources is about 54.50 MLD,
resulting in a gross supply level of about 108 lpcd for the
estimated current population of 5,03,897. This indicates a
substantial shortage compared to the gross demand level of 165
lpcd in the city.
There are three treatment plants
in the city, with a total installed capacity of 99 MLD. The
current utilized capacity is about 54.50 MLD, adequate to treat
the total quantity of water drawn from various sources.

The water distribution system in
Nanded is organized into two zones and serviced through 10
elevated storage reservoirs. The total capacity of the
reservoirs is 15.35 ML, equivalent to about 42 percent of the
total water drawn from various sources, which is adequate as per
the norm of about 33 per cent. Table 13 presents a summary of the water storage
reservoirs in the city.

The distribution network totals
to about 526 km laid out at different times since the first
water supply scheme in 1936, as presented in the following

The reach of the distribution
system appears to be substantial given that the total length of
distribution lines is about 125 percent of the total road length
of about 415 km in the city.
In terms of coverage, however,
there are only about 29,850 water connections (house service
connections), including 29,205 residential connections and 645
non-residential connections as against 62,619 property tax
assessments. This indicates a coverage of about 48 percent in
terms of properties covered. In addition to the house service
connections there are 1,472 public stand posts installed at
various locations in the city, primarily in slum and low income
settlements. These public stand posts are estimated to service
about 21,744 households. All, except 77 non-residential
connection are un-metered.
While the reach of the water
supply distribution network appears substantial, its quality and
condition are very poor, with over 60 percent of the pipelines
being over 30 years old. As a result, the system is prone to
substantial leakage. Several pipelines have now been built over
and are not accessible due to the structures over them.
Moreover, the zoning system organized for distribution as part
of the old schemes are no longer relevant and are resulting in
very inefficient supply system.
a.
The water supply system in Nanded has evolved since 1936
when the first water supply scheme was implemented. While
source of water is not a primary issue, its distribution is very
inefficient - today over 60 per cent of the pipeline is over 30
years old, and given that most of the sub-soil in Nanded is
black cotton soil, the pipeline is prone to frequent cracking
and damage.
b.
There is no proper zoning system practiced, as the
originally planned two zones are no more relevant and have been
tampered wit by way of indiscriminate connections and
cross-connections. This has resulted in a very inefficient
distribution system – in terms of leakage, head loss,
contamination and power consumption.
c.
The reach of the water supply system is largely confined
to all of north Nanded, but its coverage in terms number of
house service connections is less than 50 percent of the
property tax assessments and less than 40 percent of the total
residential units in the city.
a.
NWCMC needs to carryout a comprehensive water supply
study, including a thorough diagnosis of the current water
supply system (mapping of the existing system, leak detection
and energy audits) to identify rehabilitation and refurbishment
measures before embarking on a long-term source augmentation and
distribution network plan. A scientific zoning system needs to
be worked out the revised scheme should attempt to salvage as
much as possible of the existing network of over 500 km in an
integrated manner. The plan for water supply should include the
urban fringe areas in order to ensure economies of scale and
sustainability of the system in a long-term.
b.
A comprehensive operations manual needs to be prepared
and the municipal staff to be trained in operating the system in
a scientific manner.
