National estimates suggest that the share of urban population with access to a sewage collection network increased from 48% to 56% over 2006-11. Coverage rates are highest in the South-east region (79% of the urban population) and lagging in the North (12%) and North-east (28%) (MCid, 2014). The countiywide share of urban population with sewage treatment (through a network or local treatment) is even lower: 35% in 2011, up from 30% in 2006 (Figure 1.17). There is a wide disparity between urban and rural areas.
