The modified action plan is given below. Tirur-Ponnani river is about 48 km length. Tirur river joins Bharathapuzha at ponnani and finally reaches Lakshadweep. The identified polluted river stretch of the 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. Nine drains were identified as joining this polluted stretch. The pollution load in terms of BOD were assessed.. The map showing the drains and BOD load is given below.

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. 11 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.
