DRP News Bulletin 12 February 2018 (With Innovative Ideas Hyderabad, Chennai & Delhi Are Reviving Its Wetlands)

This week there are exemplary and encouraging wetlands revival stories from three metro cities of Chennai, Hyderabad and Delhi.  In the first example from Hyderabad, meticulously chosen plant species such as tulsi, aswagandha, citronella and hibiscus have been used to create an artificial island to clean Neknampur Lake. The treatment islands are composed of four layers of which the bamboo base keeps the entire structure afloat. Based on soil-less hydroponics, these floating treatment wetlands absorb excess nitrates, thereby reducing the chemical content of the lake water. Microorganisms present in the wetland break down organic matter while the root systems filter out pollutants and sediments. https://www.thenewsminute.com/article/3500-saplings-floating-islands-help-rejuvenate-hyd-neknampur-lake-75819 (The News Minute, 3 Feb. 2018)

Similarly, Chennai-based Care Earth Trust along with the public works department (PWD) and the civic body has managed to restore three urban lakes. While many of the smaller wetlands have vanished over time, many mid-sized wetlands seem to have shrunk by almost 65 percent. Thanks to their joint effort, invasive hyacinth was removed from the Narayanapuram Lake in Pallikaranai, while sewer lines, which emptied into the Perungalathur Lake, have now been plugged. A detailed restoration proposal has been forwarded to the PWD regarding the Korattur-Madhavaram-Ambattur lakes. https://timesofindia.indiatimes.com/city/chennai/hyacinth-out-sewer-line-plugged-three-water-bodies-restored/articleshow/62748110.cms (The Times of India, 2 Feb. 2018)

Meanwhile, Delhi Jal Board (DJB) has taken up interesting new project of creating an artificial lake in Dwarka. The project will supply water in sub-city and improve ground water level too. DJB has approved Rs. 56 crore for the project which will be completed in next seven months.  This would the first model project wherein a lake will be used to augment water supply. The special lake is being created next to the Dwarka water treatment plant (WTP) will have a sand bed to allow maximum percolation of water into the ground. It will have a capacity of 10 million gallons (MGD). The project is expected to add supply of 5-6 million gallons water to Dwarka every day.

Happy Waste Free Yamuna!

In new year 2016, State Government of Uttarakhand must act against burgeoning amount of solid and liquid waste being put in Yamuna River in its home land.

River Yamuna appears flowing pollution and waste free in Himalayan stretch. But close observations go against this popular notion and paints grim picture of huge amount of waste finding its way in the river on a daily basis.  This account highlights the issue in detail and urges State Govt. of Uttarakhand (UK) to take remedial actions before it is too late to reverse the degradation of the River. 

Yamnotri is famous shrine and thousands of pilgrims and tourists frequent the place during Char-Dham Yatra held every year. These visitors, in absence of better options or for hygienic reasons prefer using bottled water, packaged foods (biscuits, snacks) and plastic disposals as food servings. As a result solid waste in massive amount is generated through the pilgrimage season which ultimately goes into the holy river. It’s worrying that this has become a norm for past many years.

Srinagar of my thought A recent trip to Srinagar, Pauri Garhwal was educative and eventful. Myself belonging to border areas of Pauri District, I had heard village people often talking of Srinagar in casual conversation. During summer vacation, I would think of travelling to native village via Srinagar but could never explore the route. Watching snaps of Pauri and Almora towns, I imagined of Srinagar town on similar lines as a cascade cluster of modern buildings. In June 2013, the town was in news since an infuriated Alaknanda River waters had engulfed it. Continue reading “Why the Srinagar Hydro Electric Project continues to remain a threat”
