Regional Plan 2021 National Capital Region Planning Board Views & Suggestions on Chapter 8 on Water Public Health Engineering Department, Rajasthan

Rajasthan Sub Region Tehsils All 1 2 Tehsils of Alwar District Area 8380 S q.km. Composition 80% - Rural Area, 20% Urban Area Main Urban Alwar, Bhiwadi, Behror, Centres Khairthal Rajgarh and Tijara Rural 1 954 No Main NCR - Habitations Habitations Rajasthan S ub Region (6576) 4622 No Other Habitations

Water Resources The average annual rainfall in the sub region is 61 6 mm. The rainfall during the S outh West Monsoon constitutes nearly 90% of annual rainfall. Surface Water  There is no perennial river in sub region Rivers  S ome of Major S easonal rivers are :  S ahibi, Ruparel, Chuhar S idh  There is no Major Natural Lake in S Lakes & Tanks ub Region  Major Artificial Lakes and Tanks are:  J ai S amand, S iliserh, Balota Kund, Mansarovar, Vijaysagar, Kuduki Ground Water  There are 1 4 groundwater blocks in the sub region namely  Umrain, Ramgarh, Rajgarh, Thanagazi, Kishangarh Bas, Laxmangarh, Raini, Kathumar, Behror, Nimrana, Kotkasim, Mundawar, Tijara and Bansur  All the ground water blocks are in Category Over Exploited

Norms for Water Supply Towns with Towns with Rural Areas Population >= 1 Lakh Population < 1 Lakh Regional Plan 2021 200 1 35 70 CPHEEO 1 50 1 35 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 21 2 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 41 7 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 61 6 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  S tudies 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  W ater allocation to Rajasthan is 1 .1 1 9 BCM from Yamuna river.  Off- take points for taking Yamuna water are Tajewala head work and Okhala  For Alwar District, 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
