Many new smart cities came up with the idea of installing a rainwater harvesting system for combating Mumbai’s water woes and deliver a sufficient amount of water for its residents. And now the Brihanmumbai Municipal Corporation (BMC) has come up with the regulation to make rainwater harvesting mandatory for buildings with areas between 300 sq meters to 500 square meters.
It’s been a decade since BMC made it mandatory for new buildings in the city to have their own rainwater harvesting system. Ever since only one-third has managed to install the system in their buildings.
Taking the failure of installing the system into consideration, the BMC has come up with a new chapter in Draft Development Control Regulation which enlists the provision of mandatorily installing the rainwater harvesting system in the buildings. BMC released the chapter on its website and citizens have been given one week to submit their suggestions and objections.
Some of the listed things in chapter 12 are:
- For area larger than 500 sq meters, Rainwater harvesting is mandatory to be installed
- Solar water heating compulsorily to be installed in Hotels and Hospitals and in other buildings as well if possible
- Voluntary provision of the gray water system and sewage treatment plant
Provision for waste segregation and composting of wet waste
- If trees are cut, twice the number of trees has to be planted
- Definition of the high rise to be beyond 32 meters
The Draft Development Control Regulation by BMC seems strict this time stating that the owner or society shall be held responsible to ensure proper functioning of the system. Also, BMC has a provision of providing a 5% rebate to green buildings, which would implement the rainwater harvesting system properly. It means societies having rainwater harvesting systems, waste segregation, grey-water recycling, and other eco-friendly mechanisms will be eligible for the rebate.
The buildings that have successfully installed and implemented the eco-friendly measures to save water, treat sewage waste, and install solar power, shall be awarded points. These points will thereby determine the rebate on property tax.
The important features considered for buildings and housing societies are rainwater harvesting, grey water recycling plants, solid water management, segregation of organic and non-organic waste, creating manure from waste etc.
These incentives by BMC are expected to encourage the builders and residents to take the green initiative. BMC must spread awareness amongst the citizens in order to save the citizens from water crisis during peak times.
Lodha Palava- the emerging smart city located in the center of Mumbai understands the value of going green and thus has taken every step to create a sustainable city in the middle of this Metro city. Lodha Palava did it by installing water harvesting systems, sewage treatment plant, solar-powered heating systems etc. Also, leaving the major area green for nature walks and planting ample of trees inside the city creates a healthy and livable environment for its resident. Water scarcity is common in the city of Mumbai and Lodha Palava is transforming the way people are living in the cities.
