WAPCOS for conducting traffic studies for proposed waterway in 2005–06. Current traffic There is no significant traffic in the waterway except for movement of country boats which carry local produce. The main reason for lack of IWT movement is the absence of other infrastructure facilities and coordinated effort for improvements. Potential traffic NW-4 has been divided into four major cargo belts, namely Kakinada belt, Krishna belt, South Andhra Pradesh belt, and Chennai belt. Based on the survey conducted by WAPCOS, the 11 million tonnes of cargo is expected to be transported through NW-4 every year. Types of cargo include coal, rice, foodgrains, cement, fertilisers, forest products, salt, and other bulk cargo. The Godavari river system flows through the Bhadrachalam forests and coal deposits. The Krishna River flows through limestone deposits and cement industries at Jaggayyapeta. Krishna river (Wazirabad – Vijayawada) Guntur has abundant resources of limestone which are of use in cement and steel industries. Main consumers of limestone are nearby situated cement and steel industries like ACC, Andhra Cement, Parthasarathy Cements & Industries Ltd and Gauthami Cements as well as Visakhapatnam Steel Plant. Godavari River (Bhadrachalam – Rajahmundry ) The coal is a substantially available commodity in this stretch due to its nearness to Singareni Collieries (SCCL) mines. Coal fields are located in Kothagudem, Manuguru and Yellandu. Rice has a huge traffic potential in this downstream route up to Rajahmundry. In the upstream direction, traffic potential will be gained by transportation of forest products, wood pulp to Bhadrachalam where major paper mills like ITC Bhadrachalam and Andhra Pradesh paper mills (APPML) are located. Apart from this, many small paper mills are located in the East and West Godavari districts. Kakinada Canal Main cargo to be transported in downstream direction from kakinada to rajahmundry are coal, fertilizer, salt and rock Phosphate. In the upstream direction, rice bran extractions, cement clinker and fertilizers will be the main cargos for transportation. Eluru Canal Rice and other food grains, rice bran extractions, coal, fertilizer and other general cargo are the substantive commodities which can boost the IWT in this stretch. Commanur Canal The stretch from Vijayawada to Peddaganjam (Ongole) is a vital trade link connecting Kakinada belt with south A.P and Tamil Nadu. The major towns in the vicinity capable of promoting IWT are Vijayawada, Guntur Tenali and Ongole. Main traffic in the downward direction are rice and food grains. Forest products will
