Rural 1954 No Main NCR - Habitations Habitations Rajasthan Sub Region (6576) 4622 No Other Habitations Water Resources

The average annual rainfall in the sub region is 616 mm. The rainfall during the South West Monsoon constitutes nearly 90% of annual rainfall.

Surface Water Rivers  There is no perennial river in sub region  Some of Major Seasonal rivers are :  Sahibi, Ruparel, Chuhar Sidh Lakes & Tanks  There is no Major Natural Lake in Sub Region  Major Artificial Lakes and Tanks are:  Jai Samand, Siliserh, Balota Kund, Mansarovar, Vijaysagar, Kuduki Ground Water  There are 14 groundwater blocks in the sub region namely  Umrain, Ramgarh, Rajgarh, Thanagazi, Bas, Laxmangarh, Raini, , Behror, Nimrana, , , Tijara and  All the ground water blocks are in Category Over Exploited Water Supply Status

Towns with Towns with Rural Areas Population >= 1 Lakh Population < 1 Lakh Regional Plan 2021 200 135 70 CPHEEO 150 135 70

 Revised Regional Plan 2021 propose to adopt the CPHEEO norms for per capita per day water demand.  Considering acute shortage of fresh water, in Rajasthan, the norms for per capita per day water demand may be reduced to 55 LPCD for rural areas.

 A similar approach of realistic norms is recommended for NCR area with greater focus on service deliverance. This will considerably reduce burden on water resources of the area and will considerably lower financial implications. Greater Stress on Improving Irrigation Efficiencies

 Irrigation is major water consumer.  Projected water demand for Rajasthan for year 2021 includes 201 MCM for Domestic, 80 MCM for Industrial and 4249 MCM for Irrigation, thus accounting for 93.8% of total demand.  A mere 5% saving by adopting efficiency improvement measures in Irrigation sector will spare 212 MCM of water which will double the water availablability for total domestic water requirement.

 Every source for Irrigation be registered and metered. Based on soil type & crops sown, water consumption per unit land area be fixed  The infrastructure for adopting drip or sprinkler irrigation be financed appropriately. Could be cross subsidised through Domestic & Industrial water consumers  Any excess consumption be penalized. Penalties can be effectuated through electric bills. Conjunctive Use of Water

 A large area of Rajasthan sub region of NCR is having saline groundwater. About 417 main habitations and 54 other habitations are affected by saline water (As per Ramky Rural Benchmarking Report)

 For non drinking purposes, efforts shall be made to promote use of saline water, wherever feasible.

 The allocation of freshwater to individual habitation from transmission project shall be made only after consideration of proportionate use of saline water based on salinity concentration in groundwater of respective habitation

 Any excessive use of freshwater be penalized. Ground Water Recharge & Rain Water Harvesting

 The average annual rainfall of Alwar region is 616 mm thus providing adequate potential for rain water harvesting.  The ground water recharge at individual household level need to be reviewed in terms of cost benefit ratio. The rain water harvesting at individual household level shall be planned with objective of reuse only.  The first priority for rain water harvesting shall be of water reuse. Only surplus water be used for groundwater recharge  Studies need to be conducted for identification of catchment areas with good recharge potential and ground water aquifers with good retention and community level projects be developed & implemented.  Regular maintenance & monitoring of existing & new rain water harvesting schemes is a neglected field and need to be reinforced on scientific lines. Water Tariff Reforms

 Existing tariff does not act as deterrent for wasteful consumption of drinking water

 Freshwater being used for gardening, car washing etc

 Tariff rationalization as demand management tool is indispensable in present conditions

 Tariff for economically weaker section can be set on affordability principles Reduction in NRW

 The level of non revenue water is quite high in drinking water distribution networks even upto 50%.  This is mainly due to poor monitoring, old & worn-out pipelines, nearly non-existent metering

 Adoption of Universal & fully functional production & distribution metering  Installation of meters could be contracted out including long term operation & maintenance period. Cost could be recovered in affordable installments through water bill  A phased refurbishment programme for replacement of old & leaky pipelines  All new proposals for distribution networks shall only be approved if based on creation of District Metering Areas Decentralized Wastewater Treatment & Sewer Mining

 A large number of tube wells are pumping out fresh water for watering green spaces in cities.

 Use of freshwater for gardening, watering green spaces be restricted.

 For towns with existing sewerage system, sewers could be mined & treated using treatment plants with smaller footprints. These treatment plants be sited near the end-use locations thereby minimizing infrastructural costs related to pumping & piping requirements.

 This will further effect saving in augmentation works due to improvement of carrying capacity of the sewers mined.

 For towns, in which sewerage system is planned, the sewerage system & treatment plants shall be planned keeping objective of wastewater reuse in mind.

 Wastewater reuse shall be made mandatory for all new wastewater projects sanctioned. Yamuna Water

 Water allocation to Rajasthan is 1.119 BCM from Yamuna river.

 Off- take points for taking Yamuna water are Tajewala head work and Okhala

 For , with all the groundwater blocks over-exploited and no surface source, Yamuna river can be a dependable source

 but this will require settlement of inter-state issues and require Central Government intervention.

 Further, the Yamuna water available at Okhla point is polluted. It will require some immediate treatment at off take point Current Proposals
