Free Water for India

Since the inception of? EnviroChem Services (OPC) Pvt. Ltd. ?we have been seeking the possibility of providing?#Freewater?in?Tier 1 Cities in #india.?Currently, the following cities come under the Tier 1 classification of India.

1. #ahmedabad
2. #bengaluru
3. #chennai
4. #delhi
5. #hyderabad
6. #kolkata
7. #mumbai
8. #pune

These said eight cities are considered?#metro cities and #developed cities of India. The benefit of living in a #metrocity in India is the eligibility for?House Rent Allowance (HRA) #taxexemption.?For the metro cities, the HRA is computed as 50% of the sum of?Basic Salary?&?Dearness Allowance (DA).?Hence, a person employed in a metro city is eligible for a Tax exemption of 50% of the salary, enabling them to expence more on #lifestyle. These characteristics can be beneficial for the proposed model.

Considering the available population data of these eight cities and the suggested benchmark of?135 liters per capita per day (lpcd)?for urban water supply by the? Ministry of Housing and Urban Affairs (#mohua),?the #water demand along with the current #watertreatmentplant and #sewagetreatmentplant capacities of the metro cities is as follows.

1. Ahmedabad -?63,52,254 Metropolitan (Census 2011) - 82,54,560 Metropolitan (Projected 2022)?- 1,115 MLD Water Demand
2. Bengaluru -?84,99,399 Metropolitan (Census 2011) - 1,27,42,580 Metropolitan (Projected 2022)?- 1,725 MLD Water Demand
3. Chennai -?1,63,14,838 Metropolitan (Census 2011) - 1,12,27,585 Metropolitan (Projected 2022)?- 1,520 MLD Water Demand
4. Delhi -?1,63,14,838 Metropolitan (Census 2011) - 3,11,31,509 Metropolitan (Projected 2022)?- 4,200 MLD Water Demand
5. Hyderabad -?77,49,334 Metropolitan (Census 2011) - 1,02,22,490 Metropolitan (Projected 2022)?- 1,385 MLD Water Demand
6. Kolkata -?1,41,12,536 Metropolitan (Census 2011) - 1,49,90,216 Metropolitan (Projected 2022)?- 2,025 MLD Water Demand
7. Mumbai -?1,84,14,288 Metropolitan (Census 2011) - 2,06,56,390 Metropolitan (Projected 2022)?- 2,790 MLD Water Demand
8. Pune -?50,49,968 Metropolitan (Census 2011) - 68,05,950 Metropolitan (Projected 2022) -?920 MLD Water Demand

Further, the?National Institution for Transforming India (NITI) Aayog?has developed the?Composite Water Management Index (CWMI)?to enable effective water management in Indian states. Based on the CWMI of Indian states, nearly all the metro cities are in the better performing states, having CWMI of more than 50, except Delhi and Kolkata (No Data Available).

1. Ahmedabad - #gujarat - CWMI 2.0 - 75
2. Bengaluru - #karnataka - CWMI 2.0 - 59
3. Chennai - #tamilnadu - CWMI 2.0 - 58
4. Delhi - #National #Capital Territory - CWMI 2.0 - 20
5. Hyderabad - #telangana - CWMI 2.0 - 50
6. Kolkata - #westbengal - CWMI 2.0 - No Data Available
7. Mumbai - #maharastra - CWMI 2.0 - 56
8. Pune - Maharastra - CWMI 2.0 - 56

For the computation of the CWMI, #nitiaayog has considered the following?nine themes.

1. Source Augmentation and Restoration of Waterbodies - 5% (Weightage)
2. Source Augmentation (Groundwater) - 15%
3. Major and Medium #irrigation - Supply Side Management - 15%
4. #watershed Development - Supply Side Management - 10%
5. Participatory Irrigation Practices - Demand Side Management - 10%
6. Sustainable on-farm Water Use Practices - Demand Side Management - 10%
7. #rural #drinkingwater - 10%
8. #Urban #watersupply & #sanitation - 10%
9. #policy and #governance - 15%

The said nine themes had further subdivided into?28 indicators?for the computation of CWMI. For our proposed model, the following indicators shall ensure the quantification of the proposed model implementation in the metro cities.

1. Indicator 22: Urban Population Supplied with Drinking Water
2. Indicator 23: Capacity installed to Treat Urban Wastewater
3. Indicator 24: Percentage of Wastewater Treated

Further, Indicator 27: The percentage of #households being provided Water Supply and Charged for Water in the Urban Areas justifies the implementation of the proposed model in the metro cities, as the?State of?#goa has already achieved a 100% score.

Our proposed model is partially coinciding with the?One Water Approach.?For the current #watermanagement scenario, implementing the?One Water Approach,?where all the water systems, regardless of their source, are interlinked and managed to give?equal worth?to water, seems to be the best sustainable solution.

The One Water Approach ensures that the water is recycled and reused several times. The utilization of stormwater for groundwater recharge and natural vegetation, and the implementation of?#hybrid systems,?the combination of grey and green infrastructures, further ensure valuable resources to fight against water scarcity.?For implementation operation and maintenance of such hybrid systems, the need for active collaborations with all stakeholders, including communities, further ensures the implementation of the One Water Approach. Further, the proposed model will aid in solving Rural-Urban Water Disputes and constrain the Water Disputes between States of India.

Moreover, the recent NITI Aayog's draft report examining the proposed role of the?Water Regulation Authority (WRA)?in water trading of?690 Billion cubic meters (bcm)?of?surface water?and?433 bcm?of?groundwater?shall be beneficial in the implementation of the proposed model. The water #trading between the metro cities and nearby rural areas will ensure a #positivecashflow for the proposed model.

Any comments and suggestions will be appreciated.
