Nagpur 24×7 And Continues Water Supply

Vishvaraj Infrastructure sees itself as entrepreneurs in the Water, Waste Water and Transport industry; the sectors in which we have built our name are closely interwoven with the lives of the citizens. As business, apart from value creation for share holders they also impact happiness quotient of the people, thus offering massive satisfaction to us for our life transforming work. The rapidly urbanizing Indian population is expected to reach a figure close to 600 million urban people by 2031. This massive transition is creating serious challenges for urban planners and ULBs especially that of ensuring quality water supply to these citizens. Indian cities have for long lived with irregular water supply systems riddled with a variety of troubles ranging from high levels of NRW to contamination issues.

Water supply to be explained in beginner’s terms is the provision of water by public utilities, commercial organizations, community endeavors or by individuals, usually via a system of pumps and pipes. Irrigation is covered separately. Mr. Arun Lakhani had a vision for Vishvaraj Infrastructure Limited (VIL) as he considered Water Supply is a project that needs to be worked on and developed for a billion+ people in India.

Technology And Vishvarj Infrastructure Limited (VIL)

The Chairman & Managing Director of Vishvaraj Infrastructure Limited (VIL) Mr. Arun Lakhani says investing in technology is just a stepping stones to urbanized and modern India. At Vishvaraj Infra (VIL India) we consider in creating value for every stakeholder by removing inefficiencies. We deem ourselves as social entrepreneurs since Water, Waste Water and Transport; the sectors in which we have built our status are closely interwoven with the lives of people. As business, apart from value creation for share holders they also impact happiness quotient of the people, thus offering enormous satisfaction to us for our life transforming work.

Here is what Mr. Arun Lakhani has to say the entire integrated water management project for Nagpur began with a simple concept that we want to have a continuous water supply supporting Nagpur that means 24×7 water supply has to be provide to all the individual citizens. It was decided to improve the efficiency and bring in the new technology, a private sector expertise & to ensure that equitable water distribution this entire concept of 24×7 water supply or continuous water supply was brought in.

24×7 Water Supply A Dream Come True – Arun Lakhani

India receives total annual rainfall of about 4,000 billion cubic metres (BCM). After loss through evaporation etc., the total water availability is about 1,869 BCM. When you further discount topographical characteristics and hydrological constraints, the quantity of usable water is 1,123 BCM. The total availability is limited and is decreasing in direct proportion to the increase in population. According to UN data, From 5,177 cubic metres in 1951, when India’s population was 361 million, it is likely to fall to 1,140 cubic metres in 2050, when the population is projected to be 1,640 million. There is a water scarcity crisis that looms over us as we scrutinize the specifics and figures.

Out of 100 percent of usable water 80% is allocated for agricultural purpose remaining 12% and 8% proportionately shared between industrial and regular households consumption. The 20% water clearly does not look sufficient to meet the requirements of the industry and households. However, a closer look at the ground situation explains that the issue is not of scarcity but poor management and distribution of water. In the housing segment, a large portion of water is wasted because of sheer leakage in the existing water pipeline and only 70% of the total supply reaches household. The scarcity is further supplemented by low density of metering in the country leading to further limitation of funds required for basic infrastructure.

Similarly, on the industry front, it has been observed that the sector is drawing potable / ground water from rivers and other water bodies leading to further depletion of ground water levels. Providing safe drinking water, sanitation and good hygienic conditions are essential for human survival, health and dignity. Adequate and reliable water supplies and sanitation services are critical for coping with everyday urban life. Lack of access to adequate safe drinking water and sanitation causes severe health problems. Water-borne diseases –  such as dysentery, cholera and typhoid, caused by contaminated water; water-washed diseases such as skin and eye infections caused by insufficient water for personal hygiene and water-based or other water-related diseases such as malaria, bilharzias, elephantiasis and river blindness, related to exposure to unsafe water situations. Technology alone is not able to counter the water scarcity and contamination issue due to lack of skewed demography, knowledge and implementation.  It is now time to adopt the global best practices and deploy the latest technology to make the dream of 24×7 water supplies a reality.

Vishvaraj Infrastructure Ltd (VIL India) , a pioneer in Water management and recycling made it a reality in Nagpur though India’s first pilot project making it possible for the residents of the city to avail 24×7 water supply. There are few pockets in India where the aspect of 24×7 running water facility management is implemented under the PPP model and is running successfully. The most heralded project under the 24×7 running water management in India has been at Nagpur city in Maharashtra.

Nagpur 200 MLD By Vishvaraj Infra (VIL INDIA)

Nagpur 200 MLD STP Treatment-Vishvaraj-Infra

Globally water companies are developing technologies and management systems to deal with challenges faced with water scarcity and sewage water treatment. Vishvaraj Infra (VIL INDIA) however understands that the Indian context is different and it needs solutions which are local, competitive and socially acceptable. We develop implementation strategies keeping local situation in viewpoint as water is a very sensitive subject in our country. For us, driving innovations, creating sustainability, technological advancements, environmental friendliness and people’s involvement are the key drivers for the company in this sector.

Vishvaraj Infrastructure Ltd saw this as a community requirement and a industry break. In contrast the demand for fresh water is growing rapidly, estimated to go from 813 BCM today to 1,447 BCM by 2050, whereas the resource base remains constrained at 1,122 BCM. The industrial sector, which is one of the major users of fresh water, mostly puts fresh water to non-potable. Wastewater treated up to secondary level can easily be utilized for this purpose freeing up huge amounts of freshwater for domestic consumers. This can easily be achieved by improving the municipal wastewater collection, treatment and reuse thus not only recycling wastewater which is otherwise lost but also save the downstream water bodies from pollution. This is the win-win proposition of VIL’s model for the all the stakeholders, a unique example of creating value from waste whilst contributing positively to environmental sustainability.

Amongst the challenges thrown up by increased urbanization in India one of the bigger ones is massive increase in wastewater generation. The Central Pollution Control Board (CPCB) estimates that about 80 percent of the water supplied for domestic use is discharged as wastewater. This pollutes the downstream areas as it enters untreated into these water bodies. Around 38,250 MLD of wastewater is generated by class I and class II cities in India, which is estimated to grow 3.5 times to 132,250 MLD by 2050. The current wastewater treatment capacity can handle only 30 percent of the total generation, out of which only 55 percent is operational. This translates to an investment gap of over USD 7 Billion for class I and class II cities by 2016-17. Nagpur 200 MLD STP Treatment and Reuse on PPP basis. Nagpur is 10th largest Indian city with 2.5 Mn populations; Population is expected to grow to 5 Mn in the next 25 years and 3rd largest and most industrialized city after Mumbai and Pune in Maharashtra. The Objective is
Providing Sewage Treatment for 200 MLD and possible reuse by potential Customers in Nagpur. Features include: Option to sale the treated water with revenue share with Client, 100% capital investment by Operator and Annuity based payment post construction period.

Nagpur 24×7 – Orange City Water Project (OCW)

Nagpur 24x7-Orange City Water ProjectNagpur’s smart water management is an example for other cities across India. The first city to take the lead is Nagpur, Maharashtra. Now included in the smart cities list, it has inhabitants of over 2.5 million people and is the first city of its size in the nation to outsource water supply to a private operator under the PPP model for 25 years. Under the scheme the main objective was to provide 24-hour 100% safe drinking water to 100% population including slum dwellers within five years. The second objective was to reduce non-revenue water (50% water supplied to towns which is untraceable, not recorded and not paid for) to below 25% in 10 years. The project included management of the entire water cycle from production, treatment, transport, storage and delivery to the customer’s tap. It involved replacement of over three lakh house service connections, rehabilitation of treatment facilities, service reservoirs and pipelines.

“Now every household has a tap and a meter irrespective of whether it is a slum, a flat or a bungalow. There is accountability for every drop of water supplied the first time,” says Arun Lakhani, chairman and managing director, Vishvaraj Infrastructure Ltd (VIL India), which executed the Nagpur Orange City Water Project (OCW).

The aim of the project Nagpur 24×7 was to address problems of water that was being wasted and not getting billed. The city was supplying 575 million litres per day (mld) of treated water of which only 175 mld was getting billed and paid for. Most meters were either non-existent or non functional. Also, the city was receiving water supply for eight to 10 hours or on alternate days. The tanker mafia added to the problem. On the sewage side, the city was generating 550 mld of sewage and had the capacity to treat only 100 mld.

The remaining untreated sewage was polluting water bodies that supplied water to the city. For this project, the private company invested 30% of the estimated project cost, 70% grants came from the JNNURM scheme, shared by both the state and the Central government. The project was initiated by the Nagpur Municipal Corporation. This project has showcased as the model case study for other cities at the launch of Atal Mission for Rejuvenation and Urban Transformation (AMRUT) and Smart City initiative. The company also undertook a waste water reuse project for Nagpur city under which National Thermal Power Corporation (NTPC) will be reusing 200 mld of treated water from the STP for its Mauda plant. By doing so, the city will get an additional 200 million litres per day of water, which is enough for 200 lakh people.

Waste Water Reuse And VIL India

Waste Water Reuse-VIL India

India has vast prerequisite of Infrastructure building and improvement. The PPP route wasestablished in last decade also saw some lean time. With New government initiative the PPP has again come with better risk sharing matrix between private and public. Vishvaraj Infrastructure Limited (VIL) has been a proponent of PPP model, and has reputable track record in water, waste water reuse, road and highways sector.  With Urban Infrastructure foray in Water, it is today the only Indian Utility with ongoing projects in Water distribution as well as Waste water treatment and Reuse. With Water scarcity hitting the country in a big way, with sustainability point of view, VIL’s example of Total Integrated water management at Nagpur is being followed by the whole nation. Treating Sewage as Water Source and reuse for commercial/industrial purpose is key to releasing fresh water used by Industry for drinking, without augmenting fresh sources.

Waste Water Reuse – A Civic Necessity and a Business Opportunity. In contrast the demand for fresh water is growing rapidly, estimated to go from 813 BCM today to 1,447 BCM by 2050, whereas the resource base remains constrained at 1,122 BCM. The industrial sector, which is one of the major users of fresh water, mostly puts fresh water to non-potable.

VIL India Recycled Water Is A Must

Waste Water Reuse -VIL IndiaThere has to be a necessity for pushing forward innovative solutions, especially when you take into account the ecological cost and direct investments required for any augmentation of surface water reservoirs. A thought clearly mirrored by Arun Lakhani, chairman and managing director, Vishvaraj Infrastructure Ltd.

Many states have to face water scarcity issues due to the uneven distribution of water resources. The urban and domestic consumption of water has the largest scale of inefficiencies. Plus when you consider Non Revenue Water (NRW) in urban towns is more than 50% and going as high as 70-75%, it is troubling.

The urban domestic water consumption also brings out sewage of 40,000 million liters per day (MLD), which is 80% of the total water consumed. The current wastewater treatment capacity can handle only 30 percent of the total generation, out of which only 55% is operational, translating to an investment gap of over USD 7 Billion for class I and class II cities by 2016-17.

It is the responsibility of the Urban Local body (ULB) – Municipality to treat it but with the budget constraints of ULB, it automatically goes down the priority list.

VIL India  provides global solutions that contribute to sustainable development in the water sector through innovation in the design, construction and operation of drinking water treatment plants, distribution system reforms, etc. The Company has executed or in execution projects worth approximately Rs 27,500 million across the three sectors primarily through PPP contracting and few through EPC route.
