EXPERIECNES OF AQUIFER MAPPING AND GROUNDWATER MONITORING IN URBAN AREAS CASE STUDY OF BHUJ CITY PRESENTATION BY Dr. YOGESH JADEJA ARID COMMUNITIES AND TECHNOLOGIES Bhuj - Kachchh
INTRODUCTION THIS PRESENTATION HIGHLIGHTS Bhuj City and Lake System Importance & site condition of the lakes – Hydro Hydro-geological geological Aspects Water balance analysis and Contribution of Lake and its catchments in Domestic Water supply Problems & issues Planning Citizen’s Movement Implementation p
INTRODUCTION Aim Self reliant and sustainable decentralized water resource management planning for urban areas Obj i Objectives •Understand geo‐hydrological characteristics •Understand U d t d water t resource potential t ti l •Lakes and Urban Watershed •Groundwater Groundwater potential •Identify issues •Prepare water management plan •Understand demand supply scenario
BHUJ – A HISTORIC CITY HAMIRSAR LAKE • Became capital of Kutch in 1549 • Fort walls built in 1723 • Growth beyond fort walls from 1960s onwards • Population in Urban Agglomeration - 1,60,000
Water Management History of City – CLASSICAL EXAMPLE HAMIRSAR LAKE HAMIRSAR LAKE HAMIRSAR LAKE • The lake originally existed as a small pond • It is believed that the lake is named after Rabari Hamirji, who used it for his animals • About 450 years before, a well designed system was made to collect water into the central reservoir of Hamirsar Hamirsar lake was identified as an important source of water for the city • The Th system t worked k d as recently tl as 40 years ago • After the development of the bore wells in 1968 the system disintegrated completely

PROBLEM- THE HAMIRSAR CATCHMENT SYSTEM Total storage capacity of the the three lakes – 3.65 mcm Water Balance Analysis shows that the original catchments could fill the lakes with 600 mm of rainfall. Present functional catchment However, H if th the presentt system t works properly, Hamirsar will overflow in only 135mm rainfall, which is assured 80% of the years Presently, only 20% of the system is functional. functional

PLANNING - VISION Revival of Lakes and Their Catchments – Urban Watersheds Decentralized Drinking Water Schemes Groundwater Recharge Storm Water Existing Well / Bore well Recharge Campus Water Harvesting DEWATS
Revival of Lakes and Their Catchments - Urban watersheds PLANNING APPROACHES Catchment areas of all Major as well as Minor lakes Should be Developed as watershed Development Total 43 Lakes are within Urban Periphery Inflow channels passing through city area should be treated as green belts All reservoirs located in catchment areas of above lakes should be consider as part of single watershed and managed by single watershed management authority Area wise decentralized planning GROUNDWATER RECHARGE
PLANNING – MICRO WATERSHED PLANNING Entire Catchment has divided into eight sub-project areas 1a Tapka Catchment 1b Haripar Canal area 2 Hamidrai Catchment 3 Dhunaraja Catchment 4a Lakki Catchment 4b Mundra Road Talav 5 Badami Chhela Catchment 6a Mangalam area 6b Mirzapar Catchment 6c Mochirai Rakhal Catchment 7 Pragsar Talav Catchment 8 The Three lakes

DECENTRALIZED DRINKING WATER SCHEMES All areas of the city should be developed their own decentralized drinking water systems
DECENTRALIZED DRINKING WATER SCHEMES
GROUNDWATER RECHARGE All wells and bore wells should be recharged by rainwater Location of Storm should identified and converted into recharge locations by making recharge pit cum bore well
