World Water Day India 2020: Top Positive Urban Stories

The theme for World Water Day 2020 is ‘Water and Climate Change’. Indeed the changing climate has been altering the earth weather system including disrupting the water cycle.

Urban areas in India are facing increasingly severe water crisis due to mismanagement of available resources, urban flooding due to blockage and encroachments of drainage channels, pollution of water sources on account of increasing solid and liquid waste. However, there are individual, civil society group and government efforts which have been helping ameliorate the situation with rain water harvesting, pond revival, wells restoration among others. Here is a compilation of positive urban water stories from for World Water Day 2020.

DRP NB 6 May 2019: Delhi HC takes Suo moto action on RWH in Delhi

On April 16, 2019, Delhi High Court bench decided to initiate a Public Interest Litigation based on a newspaper report that not much rainwater harvesting or groundwater recharge is happening in spite of years of talk that seems to have remained empty. This is a welcome move and one hopes HC takes the issue to its logical conclusion.

DRP News Bulletin 16 April 2018: HOW Citizens can use mobile app to monitor Rivers

MOBILE APP FOR RIVER MONITORING: HUGE POTENTIAL FOR CITIZENS IN INDIA? If you added up the length of all the streams around the world, the total would be at least 89 million kilometers [Downing et al., 2012]. More than half of the global stream channel network is likely intermittent (i.e., the streams do not have flow year-round [Datry et al., 2014]), yet most streamflow monitoring stations are located on perennial streams.

WORLD WATER DAY 2018: INDIA’S POSITIVE WATER STORIES

On occasion of World Water Day 2018, SANDRP put together reports of remarkable water conservation work done by individuals, villager community and organizations across the country.

Good that UN report this WWD says[i]: “The efforts by local communities in India to improve water availability have been lauded in a UN report that highlights the importance of finding nature-based solutions to meet global water challenges…. The report notes that reservoirs, irrigation canals and water treatment plants are not the only water management instruments at disposal. It also cited the example of China’s Sponge City which aims to recycle 70 per cent of rainwater.”

But the UN report[ii] does not mention that local options should be the top priority and should be exhausted before going for large projects. Unfortunately, Indian water resources establishment’s priority is Large dams and river linking. The UN report also does not say that local systems are bound to be neglected and destroyed in the shadow of large projects and where the governance is top down, unaccountable, non transparent and non participatory.

DRP News Bulletin 19 February 2018 (How Are We Treating Our Urban Rivers?)

In this comprehensive article Mumbai-based author Vaishnavi Chandrashekhar throws the light on the plight of Uraban Rivers. “Rivers and streams have borne the brunt of the recent urban explosion in India, a nation whose population has nearly doubled in the last 40 years to 1.35 billion. Unplanned growth has led to the use of water bodies as dumping grounds for sewage and industrial effluent. According to CPCB, 63 % of the urban sewage flowing into rivers (some 62 billion liters a day) is untreated.

In addition, riverbanks, wetlands, and floodplains have been claimed over time by infrastructure, slums, offices, and housing developments – all of which has narrowed natural river channels and distorted flow, greatly reducing the ability of India’s rivers to buffer flooding. It also has taken a toll on biodiversity. http://e360.yale.edu/features/dying-waters-india-struggles-to-clean-up-its-polluted-urban-rivers (Yale Environment 360, 15 Feb. 2018)

Maharashtra Farm Ponds: accelerating groundwater exploitation, rather than harvesting rain?

Farm ponds dotting the agricultural fields immediately grab your attention as you enter Hiwargaon Pawasa – a small village of about 1500 population in Sangamner Taluka of Ahmadnagar District. The village is located just off NH-50, the national highway connecting Pune and Nashik. Farm ponds start to appear as soon as you turn east from NH-50 (which broadly runs North South) to head towards Hiwargaon. Nearly every farm, small or big, has a plastic lined farm pond. Hiwargaon Pawasa village alone has some 300 odd farm ponds.

I am here to see how these small scale irrigation facilities now set to be implemented on massive scale through the country are performing on ground. Continue reading “Maharashtra Farm Ponds: accelerating groundwater exploitation, rather than harvesting rain?”

IMD estimates rainwater harvesting potential of Maharashtra

India Meteorological Department of Pune (IMD) functioning under Ministry of Earth Sciences has recently (Nov 2016) published a study titled “Rain water harvesting potential for different locations in state of Maharashtra”.[i] The study was undertaken to assess the potential of roof top rain water harvesting based on mean annual rainfall. The need for the study was prompted by requests from a number of NGOs for information on how much rain can be harvested in Maharashtra during a good rainfall.[ii] The study basically estimates volume of rainwater (in liters) that could be harvested per sqft of roof area at 326 locations across Maharashtra where IMD stations are located.

Though this study is an important step, there are a number of ways in which such a study, which IMD plans to eventually conduct for other states as well, can be improved, in addition to a number of limitations that the study has, as elaborated subsequently.

Groundwater of Pune: An Over-exploited and ungoverned lifeline

While more than allocated and more than enough water supply from Khadakwasla Project Complex steals the water supply show in Pune, water below the ground remains pretty much out of sight and out of mind for Pune Municipal Corporation (PMC) and everyone else. Roughly estimated use close to one thousand million cubic feet (TMC) remains not just ungoverned but completely unacknowledged. Though groundwater use forms an important component of non-potable water use in the city total quantity of the groundwater extracted remains unassessed. Drilling of borewells has been going on unregulated and groundwater level has been falling at the rate of quarter of a meter per annum. Neither PMC nor any other State agencies like Maharashtra Water Resources Regulatory Authority (MWRRA functioning as State Groundwater Authority) or Groundwater Survey and Development Agency (GSDA) is governing the resource and have taken any concrete steps for its conservation.

Smart Urban Water options: Harvest rainwater, Protect water bodies

Municipal water supply systems in India are struggling to meet the demands of the burgeoning population in cities. Rapid urbanisation is increasing the freshwater demand for different purposes. Ground water being used to meet water shortages has fallen to dangerously low levels. The solution to the urban water crisis lies in harvesting rainwater and reviving local water bodies and wetlands which can store the water and help replenish ground water. It is also imperative that water is used judiciously and leakages in the distribution system are plugged.

Scarcity in water supply: Municipal agencies are struggling to supply water as water levels in reservoirs are plummeting because of the deficit rainfall in 2015. For instance, as of Jan 2016, the Navi Mumbai Municipal Corporation (NMMC) has suspended accepting applications for new supply connections until the onset of monsoon. To tide over the water shortage, the NMMC has disconnected many illegal connections, many in slum areas. It is also taking measures to prevent theft and plug leakages to bring down distribution losses which are currently 19% of the water supplied.

Respected Chief Minister,

At the outset we congratulate you for leading some progressive changes in the Water Resources Department of the State. These include decisions about continuing only with those dam projects which are more than 75% complete[1], appointment of independent people with a clean image like Shri. H.T. Mendhegiri as CADA Chief Secretary, changing norms of Economic Survey Report[2], stating that only hoarding water will not be counted towards increase in irrigation potential, etc. Continue reading “Water Smart Mumbai is possible without river links and big dams!
