Builders’ Workshop was organized to sensitize the builders about the importance of incorporating rain-water harvesting structures and sewage treatment plants in the societies, in order to make them self-sufficient and discharge-free.

Location: HSIIDC

Time: 9:30 am to 4:00 pm

Guests: Divisional Commissioner Mr. Ashok Sangwan & Deputy Commissioner Mr. Amit Khatri

Experts: Vandana Menon (Senior Design Architect), Sushmita Sengupta (CSE), Rashmi Verma (CSE), & Rajnish Sareen (CSE)

OBJECTIVES Creating awareness about :

  1. Zero waste discharge
  2. Rain-water harvesting
  3. Retrofitting
  4. By-laws & regulations
  5. Case studies


Water Positive Society – Anupriya Aeron :

  • Video depicting water utilized (in litre) per society per day
  • Rainwater harvesting system for premises more than 100 sq.m.
  • Illegal borewells and number of borewells allowed based on area
  • Utilization of run-off from sidewalks, roof-top, drains
  • Zero discharge policy
  • Sewage treatment plants
  • Uses of treated waste-water (flushing, horticulture, gardening, & irrigation)
  • Dual piping system

Rainwater harvesting in buildings and at colony level – Sushmita Sengupta CSE :

  • Reuse of water saved from rainwater harvesting; DWWT
  • Fiscal incentives to promote structures
  • Storing rainwater and recharging aquifers – quality of water being used to recharge is very important
  • Examples quoted: Baolis, North-East, Ahmedabad (tanka system), Sikkim
  • Model projects: East Nizamuddin Colony (hand-held), Cygnus Microsystems Hyderabad, Tex Corp, & Hero Honda
  • Case study : Story of a school with a rainwater system that was able to provide water to the school as it was percolating to lower areas as a result of being built on a mountain

Rashmi Verma, CSE :

  • Quality of waste-water in terms of organic, pathogenic & nutrient load
  • How composition of water determines its treatment standards
  • Difference between grey water and black water (more organic content due to faecal matter)
  • Decentralized sewage treatment plants & effluent treatment plants – low maintenance
  • Desludging frequency to prevent the settler from overflowing
  • Grey water easier to treat as compared to black water
  • Population growth aspect for the next 20 years should be considered

Ashok Sangwan, Divisional Commissioner :

  • There is no substitute for water
  • Act similar to Motor Vehicle Act
  • Enforcement drives
  • Loop-holes in the current system – need for stick mechanism
  • Ways to improve the quality of water
  • Anticipated outcomes of misuse of water

RS Bhatt, DTP Gurugram :

  • Effective ecological planning
  • Data & policies

Environment Meets Economics – Rajneesh Sareen CSE :

  • World Research Institute
  • Construction ban
  • Litigation
  • Save electricity save water
  • Circular economy
  • Vortex
  • Which plants to plant
  • Singapore guidelines
  • Microclimate
  • BREEAM rating
  • Leak detection system
  • Science is becoming complicated
  • Town planning-zero discharge township
  • Liveability index report
  • Cluster planning
  • Drastic increment in fine and its relation to lack of implementation efficiency
  • Group housing in Gurugram
  • Rain water harvesting policies

Vandana Menon – Senior Design Architect :

  • Brick, tile, cement, mosaic etc.
  • Kinds of drains, perforated covers, cleaning needs to happen before monsoon
  • Unpaved bottom
  • Bio-filter
  • Using water as a single resource
  • Dual flush
  • RO unit concealed, candle filters, not everyone needs RO – it depends on TDS, secondary container to save water draining from RO
  • Retrofitting
  • Drip-irrigation
  • Benefits of adding storage to recharge
  • Optimum use of rainwater harvesting structures – not overloaded
  • Prepaid electricity
  • Pressure reducing valve, volume dispensing tap
  • Solar energy + rain water harvesting = Self-sufficient unit
  • Staff comes 2 hrs late because they have to stand in line to get water
  • Budget for air, water, & soil?
  • Niti Ayog
  • TDS & BOD
  • Water is everyone’s right
  • Floating & migratory population
  • Correlation between efforts to get water, its accessibility, and its use
  • Water utilized in production of aerated/carbonated drinks
  • Utilization of water used to wash dal and chawal before cooking

ADP Surekha Yadav :

  • Water management is like time management
  • Importance of staying connected and informed
