ACTION PLAN FOR REJUVENATION OF POLLUTED RIVER STRETCHES

PRIORITY III/IV/V IN NAGALAND 

PREPARED BY:RIVER REJUVENATION COMMITTEE 

 

ACTION PLAN FOR REJUVENATION OF POLLUTED RIVER STRETCHES PRIORITY III/IV/V IN NAGALAND

 Introduction

  • River Chathe Originates from areas near Medziphema / Chumukedima areas of Dimapur and flows into Dhansiri River Chathe is monitored at two points at mid stream below Medziphema and below Referral Hospital. Water analysis report shows that it falls under Priority IV. The main reason of pollution is due to inflow of domestic sewage from Medziphema and Chumukedima areas.
  • Dzuna Stream (Priority III), Dzucha Stream (Priority V), Dzu stream (Priority IV) and Sano Ru Stream (Priority V) are small streams originates from Kohima district and flows through the capital city Kohima.

Biological Oxygen Demand (BOD) is one of the most common measures of pollutant organic material in water. BOD indicates the amount of permissible organic matter present in water.  There are no major industries that discharge effluents in large quantity to cause such serious contamination. Therefore, the main source of pollution is due to domestic waste and municipal solid waste which is being dumped into the nullahs & river.

The details of the five identified rivers/streams are as follows:

Name of the rivers/streams Details Identified polluted stretches Priority wise
Chathe It originates from areas near Medziphema  and flows through Dimapur and connects River Dhansiri in Assam Below Medziphema and Chumukedima IV
Dzuna Dzuna is a small river and a natural drain flowing in a west to east direction before meeting River Dzu Below Kohima Municipal Council Dumping Site III
Dzucha Dzucha is also a small river which flows in a south eastern direction and joins River Dzu Below Kohima Municipal Council Dumping Site V
Dzu Rivers Dzu is formed after the confluence of River Dzuna and Dzucha Ru River Below Kohima Municipal Council Dumping Site IV
Sano It is a small stream located at Kohima Below Kohima Town V

 

2. Objective of the Action Plan:

It is an important aspect for revival of these rivers and streams in context of its utility as it is perennial River. The ultimate goal for beneficial use of water bodies will determine the level of actions to be taken for maintaining the water quality. The requirement of river water quality for wild life and fish propagation also requires more stringent conditions and river water quality has to maintain adequate Dissolved Oxygen (DO) content so as to support survival of fish and other aquatic life.

3. The Basis of Proposed Action Plan for rejuvenation of polluted river stretches- River Chathe, Dzuna, Dzucha, Dzu & Sano Ru (Priority III/IV/V) in Nagaland.

  • Analysis reports of Nagaland Pollution Control Board & Central Pollution Control Board.
  • Hon’ble NGT order dated 03.08.2018 in the Matter of Paryavaran Samiti and Anr. V/s Union of India Ors. (OA. 593 of 2017, WP (C) 375 of 2012.
  • Order of the Hon’ble NGT (PB) New Delhi, titled “More river stretches are now critically polluted”: CPCB (OA. 673/ 2018 in the matter of news item publish in the Hindu authored Shri. Jacob Koshy.

4. Components of Action Plan:

The proposed action plan covers following components:

Source control

Source control includes industrial pollution and disposal of domestic sewage as detailed below:

a. Industrial Pollution Control

  • Inventorization of industries
  • Treatment of effluents, compliance with standards and mode of disposal of effluents

b. Channelization, treatment, utilization and disposal of treated domestic sewage.

  • Identification of towns and villages in the catchment of river/stream and estimation of quantity of sewage generation.
  • Storm water drains now carrying sewage and sullage joining river/stream and interception and diversion of sewage to STPs
  • Treatment and disposal of septage and controlling open defecation.
  • Identification of towns and villages for installing sewerage system and sewage treatment plants.

c. Flood Plain Zone.

  • Regulating activities in river/drains banks to avoid clogging.
  • Management of Municipal, Plastic, Hazardous, Bio-medical and Electronic wastes.
  • Afforestation in the catchment areas along the riverside and aesthetic plantation programs.
  • Improve irrigation practices.

d. Ecological/Environmental Flow (E-Flow).

  • Issues relating to E-Flow.
  • Irrigation practices.

5. Treatment of sewage: 

  • Department of Water Resources would undertake measurement of flow of the drains formulate Detailed Project Report (DPR) for each drain and corresponding town.
  • The flow in each drain should exclude monsoon flow. Further, any drain if receiving fresh water from any escape channel etc, should be examined for its diversion rather than mixing with sewage.
  • Sewage treatment plants for each town and related drains should be properly designed with the interception and diversion plan.
  • Sewage treatment plant (STP) and its design should be based on its full utilization capacity and ensuring simultaneous house connections to sewers as applicable to each drain and town.
  • Sewage treatment plan should also consider treatment and disposal of sewage from Villages including discharges from toilets constructed under Swachh Bharat Abhiyan.
  • Hotels/Restaurants particularly located on road-side should not dispose untreated sewage and solid waste into nearby public drain or rivers. Such establishments should be properly regulated and levied with fines in case of any violation.

6. Flood Plan Zone (FPZ)

Department of Water Resources should identify /demarcate Flood Plain Zone and regulate the activities. Such regulations would also cover

  • Plantation in Flood Plain Zone (FPZ) –By Department of Environment, Forests & Climate Change.
  • Checking encroachments-By District/Local administration.
  • Prohibition of disposal of municipal and bio-medical waste particularly in drains-By District administration/Dimapur Municipal Council.
  • Department of Water Resources, Government of Nagaland may notify FPZ – within one year.
