timeframe for completion of the project.

vi. Status of management of Septage/Faecal Sludge.

There are no conventional septage /Faecal sludge management as yet. However, a

DRDO Bio -digester are being introduced in Aizawl as a safe fecal management

option in a pilot basis. Attempt is being made to expand the project in larger areas

of Aizawl and even in rural areas as well.

1.4 Restoration of polluted river stretches

Mizoram has 9 (nine) identified polluted river stretches:

i) 1 river (Tiau) - Priority III

ii) 3 rivers (Tlawng, Tuipui and Tuivawl) - Priority IV

iii) 5 rivers (Chite, Mat, Saikah, Tuikual and Tuirial)- Priority V

6

Action Plan for the 9 rivers prepared and submitted to CPCB. Performance

Guarantee amounting to Rupees 10 Crore was submitted CPCB on 22.11.2019.

Implementation of the Action Plan initiated to meet the dateline of 31.03.2021. A

detail of implementation of Action Plan submitted to CPCB as per the format for

state-wise Review of compliance.

i. Actions taken on starting in-situ bio-remediation / phyto-remediation of sewage carrying

drains particularly for those drains joining the rivers.

Mizoram is industrially backward and there are no significant water polluting industries in the

catchment areas of the identified polluted rivers. Sewage carried by the connecting drains or

tributaries into the rivers are mostly of domestic effluents. Major portion of the courses of the

rivers pass through rural settlements and as such the Action Plan focuses mainly on the

management of Greywater which constitutes more than 90% of the total waste water generated

in the area. It is, therefore, proposed to set up Onsite Liquid Waste Treatment for generated

greywater at household level in rural villages such that zero or minimum community waste water

is generated which is considered economically viable and most appropriate for the areas under

discussion. Necessary actions have been initiated for the proposed activity and assessment being

carried out for the same.

ii. Demarcation of Flood Plain Zone (FPZ) and not encroachment in FPZ

Not applicable for Mizoram as it has no Flood Plain Zone.

iii. Good initiatives on river cleaning/beautification of ghats, sensitizing citizens to maintain

cleanliness

The Action Plan for the rejuvenation of 9 rivers in Mizoram includes mass awareness campaign

among the citizens, especially in the catchment areas through Information Education and

Community (IEC) and Capacity Building focusing on building preservation of river catchment,

clean environment and overall health, hygienic habits on use of toilets, safe disposal of wastes

etc. Actions have been initiated for this; awareness campaigns organized at community level

through participations with villagers, school children, local NGO and Govt. functionaries in

7

various forms such as cleanliness drives and mass plantation along the river courses, publications

of booklets/posters/pamphlets, campaigns through social media, local Tv and newspaper etc.

The importance of conservation of rivers through environmental education has been much

propagated in the state through school and college eco-club children. About 2000 eco clubs are

functioning in the state working towards environmental protection. Through collaborative efforts

of govt. departments and local NGO (YMA), many of the streams/rivers in the state have been

protected as reserved area which help a lot in the conservation of rivers

1.5 Air Quality Management:

Mizoram has no non- attainment cities

i. Progress on implementation of action plan as approved by CPCB - Not applicable

ii. Status on use of public grievance portal like „Sameer‟ developed by CPCB - Not applicable

iii. Status on prohibition on burning of waste:

Though the State of Mizoram has no non- attainment cities, the State Government, in

compliance with the direction of the Hon‟ble NGT in the matter of O.A No. 199/2014

has notified prohibition of open burning of wastes on lands including at landfills on

14.06.2018 with effect from 01.12.2018

One Highway construction Company at Sihmui, Sairang was fined under this Notification

iv. Actions taken on suppression of dust from various sources, etc.

Spraying of water is advocated to compress dust

SWACHH BHARAT MISSION (URBAN)

BIATE TOWN

INTRODUCTION:

Biate is one of the 23 urban towns situated in Khawzawl District of Mizoram, and

is a home to a population of more than 2500. The community of Biate has taken a

great initiative in the field of cleanliness and sanitation with the involvement of public

across the length and breadth of the town. Much before the Swachh Bharat Mission

was launched in India, Biate Town was leading by example on how to achieve

cleanliness through community participation. The principles of cleanliness is what the

elders in the community had preached and practised long before this issue has

entered the mainstream Indian consciousness. Biate has been practising community

cleaning and has remained a clean paradise since 1956. The small town of Biate has

been Malaria and Dengue Free Town since the last six years and has set a pace for

the rest of India to conform to the Swachh Bharat Mission in a meticulous manner. It

has also been declared as Open Defecation Free (ODF) Town in 2016 by the Quality

Council of India under the initiative of Ministry of Housing & Urban Affairs. It is worth

mentioning that Biate Town has won the title of ‘Mizoram Cleanest Town’ for three

years straight (2017-2019) among all the 23 Urban Towns of Mizoram. It may also be

mentioned that the first ever Indian Film Festival Mizoram jointly organised by

Government of Mizoram and Innovations India as a part of the ambitious Swachh

Bharat Mission campaign has its focus on this small town- BIATE.

PERFORMANCE IN SWACHH SURVEKSHAN

With the launch of Swachh Bharat

Mission, Cleanliness and Sanitation as an

environmental issue has been addressed

and mainstreamed throughout India.

Mizoram being one of the key players for this

Mission amongst the North Eastern States, it

has been awarded a few times in Swachh

Survekshan, a nation-wide cleanliness

survey and Biate has been the pride of

Mizoram. In Swachh Survekshan 2018, among the 4041 ULBs participants, Biate Town

was awarded ‘Best City in Innovations in the North East Zone’ and had secured 2nd

Rank in the North East Zone with a score point of 2217.

INNOVATIVE ACTIVITIES

Like any other town in Mizoram, Biate

has also been a large consumer of

plastic items and polythene bags. To

divert these plastic wastes from ending

up in dumping ground and to raise

awareness on the harmful effects of

plastic items, Biate Town has placed

separate bin for plastic waste in 14

localities within the town. These

collected plastic wastes are recycled

as far as possible and the remaining

waste are sold to recycling agencies. E-Waste Collection Centre has been set up

within the town and both e-waste and hazardous waste are collected once in a

week. Biate Town has shown an exemplary record in innovative ways of re-using

plastic bottles and other non-biodegradable waste. Such waste are re-used for

beautification of the town in the most colourful and attractive manner adding

aesthetic elements to the town.

CLEANLINESS AND SANITATION INITIATIVE

Under ‘The Mizoram Urban Sanitation and Solid Waste Management

Policy,2011’ , Biate Town Sanitation Task Force was established on the 19th of July, 2018

with the concerned Nodal Officer as its Chairman with other functionaries and NGO

representatives as its Members. Under this, ‘Biate Faina Committee’- Biate Town

Sanitation Committee was set up and all 14 localities of the town has their own Area

Sanitation Committee to carry out the task and plan formulated by the higher

committee and to further execute the work in their own areas. Regular mass cleaning

drive has become a routine for the community and the spirit of community

participation is what makes Biate stands out from the rest of the towns. Unlike other

cities and towns, the ‘dirty work’ of ensuring the town remains clean is not assigned to

members of poor and marginalised communities, but a collective responsibility. The

VC also paid attention to maintaining side drains to ensure hygiene of the whole town.

Funds collected from the residents and VC allowed locals to construct and maintain

their side drains. It is all because of the efforts put in by the community and town

leaders that Biate Town is a vector-borne disease free town.

WASTE MANAGEMENT INITIATIVE

In Biate town, segregation of waste at source has been submissively practiced.

Residents segregate their waste into wet and dry. Dry wastes are collected separately

and are either re-use or sent to recycling agency, while the rest is dumped into an

open ground 2 km from the town. Meanwhile, the wet waste is taken to a vermi-

compost plant, which functions under the supervision of certified personnel in Vermi

composting. 100% Door-to-door collection of waste has been practiced in all

households with a monthly charge of Rs. 50/-. Regarding waste management, local

community takes the ownership to manage their own waste and ensure that

functional sanitation systems are put in place.

With that being said, it is safe to say that Biate Town is a living example of what

selfless contribution can attain in accomplishing a cleaner and healthier community.

A. Control of Illegal Ground Water Abstraction : Not applicable as there is no illegal ground

water abstraction in the catchment areas.

B. River catchment/ Basin Management : For river catchment/basin management

several action plans have been formulated

such as, Plantation, Siltation and Soil

Erosion Control by various schemes such as,

Runoff retardation, Gully Control, River

bank erosion control, Silt Retention and

Landslide Control and ground water

charging through rainwater harvesting.

Plantation and Rainwater harvesting have

been started.

DPR for Siltation and Soil Erosion

Control under preparation.

C. Flood Plain Zone Protection : Not applicable in Mizoram as there is no

flood plain zone in Mizoram

D. E Flow maintenance & Watershed Management : It is proposed to increase the volume and

maintain flow of the rivers by rain water

harvesting and by protection of existing tree

coverage/natural vegetation within the

Riverine Reserved Forests and plantation

drives.

E. Ground water recharge/ Rain water harvesting : Rain water harvesting program has been

initiated in the catchment areas:

Completed:

i) Bungtlang, Denlung Villages (Mat river)

ii) S.Kanghmun (Tlawng river)

iii) E.Lungdar village (Tuipui River)
