India’s Economy

• India has grown at an average of 8% GDP on an annual basisin the last decade.

• India is poised to be the 3rd largest economy by year 2030 andthe largest by 2050 in the world according to InternationalMonetary Fund and World Bank reports.

• India will be a fully developed country by the Year 2030resulting in huge infrastructure projects.

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 millionby 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 growthacceleration in the past decade & by 2030 the urban sector willbe contributing 70% to 75% to the country's GDP.

• By 2030 - 6 mega cities with >10 million population, 13 citieswith >4 million people each and 68 cities with population ofover 1 million each.- McKinsey Report

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 nonagricultural pursuits.

• Urban Agglomeration – Continuous urban sprawl abutting a town

• Out Growths – A village or hamlet near a statutory town possessing urbanfeatures like pucca roads tapped water drainage and amenities etc.

Massive UrbanizationSmarter Ways to Manage Utility Infrastructure

• By the year 2050, the number of people living in Indian citieswill touch 843 million.

• To accommodate this massive urbanization, India needs to putin place synergizing master plans with utility infrastructure.

• Advancing utility infrastructure by finding smarter ways andusing technology to manage complexities, reduce expenses,increase efficiency and improve the quality of life.

Introduction - Hassan City Hassan City District Headquarters of Hassan District in Karnataka and boasts one

CDP Conurbation Area = 67.19 Sq kmPopulation Projected for 2021= 4.0 Lakh Souls

CMC Area = 26.50 Sq km

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 beone among the Economic Hubs for Industrialization, & AgricultureProduce, and Processing, Major Research and Educational Sector,Major Industrial Development, Heritage center, Transport andConnectivity Employment Front

• Hassan has Prestigious Indian Satellite Master Control Facility andAnthariksh Nagar within CDP Limits

• Recognising the potential of Hassan GOI sanctioned Industrial GrowthCentre 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 anSpecial Economic Zone ( SEZ) in 591 Ha abutting the Hassan City.

• Special Airport has been sanctioned to handle Cargo and the Airport isfalling within the CDP Boundary.

• Capital city Bangalore has been recently connected by upgrading to 4 laneHighway and by rail route.

Population Projection and Water Demand After Analysing the Last Decade Population Census it is evident that Hassan is poised for explosive growth due to economic Activity

Water Supply Master Planning 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.

Unique Features of the Smart Utility

100% reliable source of water as the jack well is proposed on thedownstream of the Hemavati Dam.

Entire feeder main network (83.92 km) and distribution network(707.75 km) is designed to work on gravity and hydraulicallybalanced, using automatic hydraulically actuated valves, like flowcontrol valves, pressure relief valve, pressure management valve,level control valve, surge protection valves, pump managementvalves 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 supervisorycontrol and data acquisition with automation and instrumentationand software (SCADA).

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.

Entire network reporting, CRM, customer billing generation, e-commerce, payment receipts, HR ERP, account management etc.
