It is estimated that Delhi generates around 4,000 tonnes of construction waste daily, the Delhi Metro Rail Corporation being one of the major contributors to this waste. But, unlike other organisations who hardly take the onus of managing such waste, DMRC has found a novel way to tackle the problem and in the course setting an example for others to follow.
Prakriti – Metro Park is one of a kind park oriented towards creating greener public spaces in the capital by using construction waste. Spread over an area of over 10 acres, the park has a host of recreational as well as artistic attractions. Facilities such as an auditorium, amphitheatre, meditation alcove, playground for children and gymnasium have been provided for the visitors. A lake with fountain along with a rain forest has also been created in the park.
The main highlights of the park are the artistic installations created from waste materials generated from the Delhi Metro’s construction sites. Artists from across the country have come together to create these beautiful installations, all of which carry pertinent messages on a range of issues. Almost one third of the materials used in the park are salvaged materials.
Delhi Metro’s care for the environment has also been depicted both in the design as well as the eventual construction of the park. An environmental gallery has been created which has paintings about the importance of environmental protection. Utilisation of top soil from various underground station sites, plantation of nature, medicinal and pollution absorbing plants, bird attracting species, creation of a ‘Rain forest’ etc. are some of the other green attractions of the park.
Because of these features, the park has also received a Platinum rating from the Indian Green Building Council (IGBC). The water required for horticultural use will be provided by the Sewerage Water Treatment Plant (STP) in the vicinity and 20 kW of power requirements will be met by solar power generation making it a net positive energy park.
For irrigation purposes also, treated water is being used. Arrangements for rainwater harvesting has been done for 100 percent runoff water from the site. Almost 97 percent of plant species are native enabling water use reduction. Nearly, 90 percent of construction materials used are also local materials. During the construction work, no construction waste was sent to landfills, instead waste materials from other DMRC sites was reused. The organic waste generated at the park is also being treated.
Another highlight of the park is the Trellis Court which has eight pillars of progressively increasing height in the centre which depicts the evolution of Delhi Metro from a nascent organisation, which took up the challenge of encompassing Delhi with metro network to a confident and evolved organisation which is now in the process of completing many new lines.
