2. India’s Economy
• India has grown at an average of 8% GDP on an annual basis
in the last decade.
• India is poised to be the 3rd largest economy by year 2030 and
the largest by 2050 in the world according to International
Monetary Fund and World Bank reports.
• India will be a fully developed country by the Year 2030
resulting in huge infrastructure projects.
3. Urban Challenges & Opportunities
• Rapid Urbanisation.
• Urban population grown from 286 million in 2001 to 377
million in 2011, constituting 31.16% of the population.
• India is on the "brink of an urban revolution" with its
population in towns and cities expected to reach 600 million
by 2031 or 40 percent of the population of 2031.
• India's urban sector presently constitutes 63% of India's GDP
(up from 45% in 1990) and has been its key engine of growth
acceleration in the past decade & by 2030 the urban sector will
be contributing 70% to 75% to the country's GDP.
• By 2030 - 6 mega cities with >10 million population, 13 cities
with >4 million people each and 68 cities with population of
over 1 million each.- McKinsey Report
4. No of Towns / Cities
• Census Town – Minimum population 75000 with Density of 400/sq. km.
and having at least 75% of the male working population engadged in non
agricultural pursuits.
• Urban Agglomeration – Continuous urban sprawl abutting a town
• Out Growths – A village or hamlet near a statutory town possessing urban
features like pucca roads tapped water drainage and amenities etc.

5. Massive Urbanization
Smarter Ways to Manage Utility Infrastructure
• By the year 2050, the number of people living in Indian cities
will touch 843 million.
• To accommodate this massive urbanization, India needs to put
in place synergizing master plans with utility infrastructure.
• Advancing utility infrastructure by finding smarter ways and
using technology to manage complexities, reduce expenses,
increase efficiency and improve the quality of life.

7. Importance of Hassan City
• Hassan City is experiencing and achieved tremendous growth
(about 30%) in the last decade and has created a potential for itself to be
one among the Economic Hubs for Industrialization, & Agriculture
Produce, and Processing, Major Research and Educational Sector,
Major Industrial Development, Heritage center, Transport and
Connectivity Employment Front
• Hassan has Prestigious Indian Satellite Master Control Facility and
Anthariksh Nagar within CDP Limits
• Recognising the potential of Hassan GOI sanctioned Industrial Growth
Centre in Hassan in an area of 2000 acres, abutting the Hassan CMC.
Many major large industries have come up
• Karnataka Industrial Area Developed Board has taken up to set up an
Special Economic Zone ( SEZ) in 591 Ha abutting the Hassan City.
• Special Airport has been sanctioned to handle Cargo and the Airport is
falling within the CDP Boundary.
• Capital city Bangalore has been recently connected by upgrading to 4 lane
Highway and by rail route.

CMC Area = 26.50 sqkm.
Population Projection 531208 (30 years and ultimate year 2046)
Master Plan Prepared CDP Conurbation Area = 67.19 sqkm.
Population density mapping was done and classified areas were
classified as densely, moderately, and sparsely populated.
According to population density and CDP Land use Population was
distributed in the entire conurbation area.
Population @ 100 per ha. was distributed on undeveloped area
Water Demand was considered at 135 LPCD for domestic purpose
Institutional as per actual survey and Fire Demands were
considered as per CPHEEO to make the water supply scheme
viable by considering Demand for Airport, and Dairy Industry etc.
Ring feeder main with loop design concept was planned to cater to
any demand created in undeveloped area.

12. Unique Features of the Smart Utility
100% reliable source of water as the jack well is proposed on the
downstream of the Hemavati Dam.
Entire feeder main network (83.92 km) and distribution network
(707.75 km) is designed to work on gravity and hydraulically
balanced, using automatic hydraulically actuated valves, like flow
control valves, pressure relief valve, pressure management valve,
level control valve, surge protection valves, pump management
valves etc.
In distribution the minimum pressure at nodes is 10 m (10-22m=64
%, 22-30m=30%, >30=6%).
Entire system from source up to consumer end is on supervisory
control and data acquisition with automation and instrumentation
and software (SCADA).
13. Unique Features of the Smart Utility
Real time monitoring of pumping machinery, like health of pumps
with energy and water audit capabilities.
Real time leak detection on pressure mains including pinpointing
location of the leak.
Statistical modelling for leak detection for feeder main and
distribution network, and within consumer end.
Consumer water meters used are automated meter reader with data
transfer on fixed system delivering meter readings in real time, with
capability to sound alarm for leakages, and unaccounted for water at
consumer end.
IT with GIS enabled monitoring of the scheme with demand supply
management, operation & maintenance, mobile application, with
unique capability of deriving real time water rate per kilo litre.
