CHAPTER 1

INTRODUCTION

Tirur River begins in the Tirur taluk, Athavanad village in Malappuram district of the

Kerala state in south India and flows south-west to Thirunavaya and then north-west to

Elamkulam where it turns south-west, joining the Bharathapuzha River, which flows into the

Arabian Sea near the coastal town of Ponnani. It is known for its beautiful mangroves and its

many varieties of fishes and birds.

Tirur River, in Malappuram district is navigable and forms part of west coast water

transport system. The river now faces significant challenges for its survival. The main objective of

the study was the assessment of the water quality of the Tirur River and identified polluted river

stretch.

The water Quality Assessment of Tirur River has provided information on the status and

magnitude of pollution with respect to desired water quality. The long term trends of water quality

assessment have formed the basis for identification of Tirur river as polluted in its entire length.

1.1 Municipal sewage generation and treatment

The water quality deterioration was caused by the discharge of various industries like service

stations,auditorium,hospitals,hotels, markets etc.situated in the Tirur municipal area along the river

stretch. The effluent discharges from vegetable and fish market, bus stand and comfort station of

Tirur municipality is also discharged into this drain.The residences located on the banks of the

river also contributing their part to aggravate the situation. The various organic matters

accumulated in the river caused in tremendous reduction of dissolved oxygen. But as per

WP(C)27528/2012 of NGT almost all the Industries,hospitals and auditorium have provided

ETP/STP .At present the main source of pollution is the kaithodu,the public drain passes through

tirur Municipality and leads to Tirur River.

12

1.2 Watershed

The main watershed area in Tirur river are Mangalam ,Purathur,Thripangode and

Thalakkad.

1.3 Land use

Broadly, four types of land use can be seen in the district. A large part of the area,

especially the coastal tract and the midland areas come under arable land, used for cultivation of

different crops, both irrigated and non-irrigated. The coastal tracts are densely inhabited. Forests

are seen along the east and north, forming part of tropical evergreen forest supporting a variety of

plant and animal life. Cashew and rubber are the main commercial crops of the area. The thick

laterite ‘duricrust’ capping the hillocks generally does not support any vegetation, hence such areas

are demarcated as wasteland.

1.4 Soil type

On the basis of morphological and physico-chemical properties, the Soil Survey Division

of Department of Agriculture, Govt. of Kerala has classified the soils of the district into the

following types:

Soils of the low lands (Alluvial soil)

Those are mainly seen along the coastal plains and valleys. The soils range from

exclusively drained to moderately/well drained sand to sandy clay in nature.

Soils of Mid/Up lands (Lateritic soil)

These are mostly lateritic soil, and is seen along the mid land portion of the district. These

are deep to very deep, well drained, and gravelly to clayey.

Soils of Central Sahyadri (Hydromorphic soil)

These are deep moderate, well drained and clayey soils with high gravel content. Erosion

is moderate to severe. Hard laterites with rock out crops are present.

Soils of eastern part of Malappuram (Forest loamy soil)

1,698,645 • Metro

Population

(2011)

• City

These soils are deep or very deep and well drained with loamy to clayey textures and having

fairly high gravel content.

1.5 Human Population

1.6 Rainfall and Climate

The district has more or less the same climatic conditions prevalent elsewhere in the State

viz. dry season from December to February and hot Season from March to May, The south-West

monsoon from June to September and the North-East monsoon from October to December. The

normal rainfall 0f the district is 2793 '3 mm' out of this major rainfall contribution is from south

West monsoon followed by the North East monsoon. The south west monsoon is usually very

heavy and nearly 73-5% of the rainfall is received dung this Season. North East monsoon

contributes nearly l6'4% and March to May summer rain contributes nearly 9.9% at d the balance

0'2oh ts accounted for during January and February months.'

1.7 Activities

Agriculture and fishing are the main activities in Tirur River. At present there are no

industries along the banks of river directly discharging the effluent into the river The River

falls under priority IV category as per CPCB categorisation based on BOD values.

18

2.3 Results of river water quality

As per the order, the stretch to be studied is Naduvilangadi to Thalakadathur .

There are five sampling points in Tirur river as per NWMP. They are koolulpalam, ezhur,

thalakadathur ,thazhepalam and mangatiri from upstream to downstream..We have taken one

sample from Naduvilangadi for analysis. .Naduvilangadi is located in between Thalakadathur and

Thazepalam .The drainage from Tirur river joins at Thazhepalam..

19

In both upstream and downstream areas, field surveys were conducted. Water samples collecting sites were selected on the basis

this preliminary studies and its impact on ecosystem. An interaction with local people living in the surrounding of the sampling sites were

also done and gathered information regarding agriculture, water availability, water quality and socio-economic status. The water quality

parameters namely pH, conductivity, total hardness, dissolved oxygen, biochemical oxygen demand (BOD),COD ,Sodium and total

coliform were analyzed as per standard methods .

The water quality of the Tirur River is better during rainy season due to high river flow compared to the summer season .Results of

the physicochemical parameters indicated that water in Tirur river is contaminated and not safe for drinking and it is also unhealthy for

the aquatic life. The microbiological examination of river water in respect of Total Coliform/100 ml has confirmed that the river water is

unfit for direct consumption, bathing or any other domestic use.

` The water analysis result of tirur river (past 2 years and recent) is attached to this report.

2.4 Results and Conclusion

The parameters shows seasonal fluctuations and the pollution was more in summer compared to the rainy season. Temperature of

environment and river affects the physico-chemical parameters of water. The increase in water temperature leads to the speeding up of

chemical reactions in water, reduces the solubility of gases and amplifies the taste and odour. Temperature of Tirur river water ranged

from 28.5°C to 32.6°C. The pH range suitable for the existence of most biological life is quite narrow and critical, and is typically 6-9.

The pH value of the water varied from 6.4 to 7.5. pH range between 6.5 and 9.5 has been found to be suitable for fish production

. The pH values of all the sites during the sampling period were within the prescribed limits (6.5-8.5) as per standards.

25

The conductivity values in the water samples ranged from 68 to 31000 μS/cm. According

to BIS standards, the desired limit of electrical conductivity of river water is 50 to3000 μS/cm.

From the result of the present study, it is noticed that Electrical conductivity of the water samples

at various sites of Tirur river are exceeding the desired limit.

Total hardness in the river vary from 10mg/L to 3200 mg/L. Total hardness of surface

water varied according to seasons. The analysis revealed that the total hardness of water exceeded

the desirable limit during summer season (as per BIS, desirable limit is 200mg/L and permissible

limit is 600mg/L. The increase in hardness may be due to the domestic activities like washing of

clothes, animals, vehicles etc. in the river. oxygen concentration ranged from 2.1 to 7 mg/L in the

study. The low levels of DO concentration in the fresh water aquatic systems is an indication of

high levels of organic pollution . During summer, dissolved oxygen concentration is low in this

stretch. From this it is clear that Tirur River water is unfit for the survival of aquatic life in summer

season.

As per the analysis report BOD values ranges from 0.2-4.4mg/l. The highest value 4.4

mg/L is obtained in May and October 2018 at THALAKADATHUR

Total Coliform value ranges from 12 to 280 TC/100ml in 2018 .E.coli in fresh water can

indicate the presence of pathogens from animal or human feces. The higher value of coliform

bacteria and organic pollution is mainly due to discharge of septic waste and wastewater directly

through small drains into the river.

Survey conducted in the study area revealed that the main problem in Tirur river is due to

the dumping of garbage and solid waste (including poultry waste), direct sewage discharge (from

houses, hotels and markets) and discharge from small industries are the main reason for Tirur river

pollution. Transformation of paddy lands for various purposes, and filling up of ponds, natural

streams and canals in between the dry lands also affected water quality and the flow of Tirur River.

Constructed encroachments of urbanization (especially in and around Tirurtown) and

encroachments by villagers within river corridors and floodplains are frequent in the river bank.

The channel of Tirur River is shrinking and vacated land is getting available for human

settlements, which are mostly unplanned, and therefore, obstructing the original path of rivers

leading to high risk. Encroachment increases impervious cover adjacent to rivers and thereby

26

increasing the rate and volume of runoff, loading of sediment and other pollutants, and temperature

of the receiving water .

From the analysis report the Minimum,Maximum and Average values of the parameters are shown

in the table.

The identified polluted river stretch in Tirur river is from Naduvilangadi (at poroor, 2 km

away from Naduvilangadi junction) to Thalakkadathur. This stretch is a part of Tirur-Ponnani

river flowing across Malappuram district. The total length of the polluted stretch is 4 to 5 km. No

tributaries are joining at this stretch. The total length of the Tirur-Ponnani river is about 48 km.

Tirur river joins Bharathapuzha at ponnani and finally reaches Lakshadweep.

KSPCB is regularly monitoring at 5 points viz., Koloopalam, Ezhur, Thazhepalam,

Thalakkadathur and Mangattiri under NWMP/SWMP. The analysis result for the past 4 months

at these points is attached as Table.1.

CHAPTER 4

ACTION PLAN FOR TIRUR RIVER

As per the order G.O(MS)No.12/2019/WRD dated 30.04.2019, District level Technical

Committee has been formed and the first meeting was conducted on 18.05.2019 at KSPCB, DO,

Malappuram chaired by the Chief Environmental Engineer, KSPCB, Regional Office,

Kozhikode. The minutes of the meeting is attached as Annexure 2. In the meeting, it was

decided to conduct a joint inspection at the polluted stretch. The team comprising of the

following officers conducted joint inspection on 20.05.2019

1. Assistant Executive Engineer, Assistant Engineers from Irrigation department, Tirur

2. Program Officer, Suchitwa Mission, Malappuram

3. Secretary, Tirur Municipality

4. Environmental Engineer, Assistant Engineer, Assistant Scientist, Kerala State Pollution

Control Board, District office, Malappuram. The team inspected the following sites

1.Thalakkadathur Bridge

No huge dumping of wastes was seen at the area during inspection. But some plastic

covers (waste) were seen deposited on the banks and in the river stretch. Irrigation department

informed that it will consume a good amount of time for conducting desilting activities and

hence as an immediate measure, the municipality was instructed to initiate action to hand pick

wastes in boats by workers. In order to avoid further dumping, cameras are to be installed and

metal fencing to be provided on either side of the bridge. One side comes under the municipal

area and the other side under Cheriyamundam grama panchayath. KSPCB has already assessed

the waste water treatment systems provided at the nearby industrial units, viz., A.M Motors,

Kadeeja Auditorium, Safiya Auditorium, Al Noor Hospital located at Thalakkadathur near banks

of the river/near the bridge. A show cause notice has already been issued to M/s Al Noor hospital

39

on account of non-functioning of STP in the unit. KSPCB shall monitor the progress. No open

discharge was seen at these points.

2.Old Ponnani thodu (North Annara)

It is also known as old ponnani thodu, comes under Tirur municipal area. During

inspection, about 3.8m length stretch of the thodu was seen stagnated with plastic bottles,

covers, coconut husk etc. and also the width of the thodu was seen reduced. Irrigation department

should take action to preserve the width and the municipality is liable to take action for cleaning

this portion. Irrigation department agreed to provide a shutter at the point to avoid further reach

of wastes at the old ponnani thodu . No open/direct discharge was seen at this point from any

unit.

3.Thazhepalam Railway Byepass road

A drain containing waste water from the waste water treatment of Kerala Water

Authority plant is seen joined at Thazhepalam. Notice issued to KWA by KSPCB. At the area

plastic bottles, covers, coconut husk were also seen scattered which is to be cleaned by the Tirur

municipality.

4.Vanchichal(behind Tirur Railway station)

Vanchichal (behind Tirur Railway station) is identified as the most polluted area in the

stretch. Due to the accumulation of waste slurry and silting, water was seen stagnant and

infiltration of the same polluted water was found to reach the Titur River stretch. The major

pollution source at this point is from Tirur Railway station. No effective liquid/solid waste

treatment system has been provided at the station. KSPCB issued Notice to Tirur Railway

station.

5.Tirur Municipality Fish Market

With the great effort of municipality, the issue prevailing before has been solved for the

time being. At present the waste water is contained at the market itself and no waste water

reaches at the stretch. Effluent Treatment Plant already provided at the market need revamping

and it is progressing. At present no discharge was seen flowing outside from the market.

40

6.Mangattiri bridge

Thalakkad grama panchayath provided net at both sides of the bridge to avoid the reach

of solid wastes near the bridge. At present no wastes are seen dumped there.

7.Ettirikkadavu

A drain (storm water) was previously present at this area and the BOD value was

analysed and measured as 4.1 mg/l. But the team visited the site and at present, there was no

direct discharge seen at the point and no visible drains.

8.Panampalam (in Cheriyamundam Panchayath) Bridge

Solid wastes are seen dumped at the site near the Masjid. Camera need to be provided by

the Cheriyamundam Panchayath as the area is under their jurisdiction.
