NKUSIP (Package II – Belgaum)Tranche II Sub-projects in BadamiTMCInitial Environment Examination (IEE)34. c) Roads and Drainage: All the declared slums are well connected with roads. Themain roads and the internal roads are of cement concrete. SSM and RCC precast drainsare provided on either side of the roads in slum. Under this programme, it is proposedto provide WBM with Asphalt and concrete to existing roads, to provide new concreteroad and RCC drains wherever required.2.7 Proposed Improvements for Program Components of Badami TMC2.7.1 Urban Drainage System35. The proposal for this project includes improvement of the natural nallahs and secondarydrains. If it is found necessary, the drains will be covered with slabs to avoid thepossibility of dumping of garbage and other solids largely. The drainage proposal forBadami TMC is presented in Table 2.7.Table 2.7: Proposed Improvement of Drainage SystemSl.NoDescription of worksLengthin Mts1. a) De-silting, removal of debris and vegetation of Nallah no.1 (Avg. nallah width 14 mts) 3000b) Nallah no.1 side protection with construction of un-coursed rubble stone masonry inCC 1:4 including exposed surface pointing etc. (2.0m width & 1.75 m height)2. a) De-silting, removal of debris and vegetation of Nallah no.2.

The drainage network is along the existing roads. No additional drainage line isproposed, as existing lines will be used. No further difficulties in terrain and majorcrossings are found along the drainage lines.6261470881KUIDFC 19 SPAN
