NAG RIVER : WASTE WATER MANAGEMENT
• Strom water discharges• Hotel and Offices• Agricultural runoff• Landfill leachates• Industrial wastewater• Shopping Mall dumping site
• Odor problems • Mosquito nuisance and breeding of insects• E-coli and other pathogenic micro-organisms can
contaminate drinking water sources• Spreading of communicable diseases like cholera,
dengue, malaria, etc• Impact on bathing quality of rivers,etc. • Ground water pollution• Contamination of water of Gosikhurd National Project
SOURCES
IMPACT
Avoid contaminations in river water
Decentralize approach for treatment
Recycle and Reuse of Waste Water
URGENT NEED
REMEDIAL MEASURES
Remove Encroachment
Disconnect of sewage lines
Recycle - Reuse
Adequate STP
Regular monitoring IEC activities
Protection of Origin
Solid waste managementPhyto-remedation
Mitigation Techniques: Phytoremediation
TOLERANCE MECHANISMS FOR INORGANIC AND ORGANIC POLLUTANTS IN PLANT CELLS.
DETOXIFICATION GENERALLY INVOLVES CONJUGATION FOLLOWED BY ACTIVE SEQUESTRATION IN THE VACUOLE AND APOPLAST, WHERE THE POLLUTANT CAN DO THE LEAST HARM. CHELATORS SHOWN ARE
GSH: glutathione,
Glu: glucose,
MT: metallothioneins,
NA: nicotianamine,
OA: organic acids,
PC: phytochelatins.
Active transporters are shown as boxes with arrows.

Phytoremediation : Plants & Performance
NEERI Nagpur: Proposed design of Phytorid
Estimated land area required: 2563 m2
For a plant capacity of 1000 m3/day
Entire length of the plant: 267mFor a plant capacity of 1000 m3/day
Length of the Phytorid bed: 184 mDimension: 1.5m depth X 184m length X 8m width
Project completion period: 12 months
ADVANTAGE: Economic
Operation and maintenance expenses are negligible.
Minimum electricity requirement
Smaller footprint (Retention time: Typically less than 24 hrs.)
Facilitates recycle and reuse of water
No foul odor and No Mosquito Nuisance.
Tolerates fluctuations in operating conditions such as flow, temp, and pH
CONCLUSION • The Nag river - Pill river water is severely polluted.
• It is urgent need to take various effort to rejuvenation the Nag river as well as water of Gosikhurd National Project.
• Regular Monitoring is needed to check water quality of river.
• Adequate number of STP, decentralise systems, phyto-remedation are required.
• Removal of encroachment to maintain the flow of river.
• Awareness campaign/IEC for the protection of Nag river.
