Draft Detailed Project Report

Technology Centre Systems Program – Draft DPR for New TC at Rohtak
► The septic tanks will have adequate manholes for cleaning and maintenance purpose and will
also have gas vents rising above the highest level of the buildings to avoid foul smell.
► Overflow outlets of the septic tanks will be connected to secondary treatment achieved
through properly designed constructed wet land system with sub-surface flow.
► The constructed wetland will consist of locally available species of wetland trees, bushes and
shrubs.
► Collection tank of adequate capacity will be provided on the upstream of the constructed
wetland to take care of incidental heavy flows.
► The constructed wetland will be located suitably in the premises allowing adequate sunlight
for growth of plants throughout the day.
► Provision will be made to allow rejection and regeneration discharge from water treatment
plant by dissolving high TDS water suitably.
► Necessary de-odouring and chemical dosing will be provided at the end of wetland before the
water obtained is reused.
► All equipment used and the design, arrangement will be in compliance with applicable rules
and regulations as laid down by town planning authority, central pollution control board and
other local authorities.
Ventilation system
a) Internal buildings
► The TC premises will have provision for sufficient ventilation. This will be done keeping in
view the amount of space in the TC, number of people expected to occupy the space, type
and amount of machines/equipment, and overall size of the space. The designing will be done
keeping in view proper distribution of air for ventilation throughout all occupied spaces
across the TC.
► Natural ventilation - The premises will have adequate openings, such as doors, windows
and/or vent opening to clean environment. Roof vents would be placed wherever applicable
to reduce the reliance on air conditioning systems and also reduce CO2 emission in the
building.
► Mechanical ventilation – Mechanical parts would be installed to provide air to building
occupants at a comfortable temperature and humidity that would be free of harmful
concentrations of air pollutants.
► Provision for adequate supply of outdoor air in the indoor environment will be provided to
dilute pollutants released by equipment, building materials, furnishings, products, and
people. The building’s ventilation system will be properly installed with filters to trap such
particles.
► Air input, smoke exhaust will also be installed and maintained for proper ventilation.
