We look at the challenges of water management in 12 towns from four corners of the Himalayan region that are facing challenges of changing water budgets, increasing water demand, and water scarcity. We map future challenges that these towns will face in a “business-as-usual” scenario. These cases draw from primary research and fill an important knowledge gap about the status of water resources and water supply in Himalayan towns. We highlight the concerns around unplanned and haphazard development in the region, which is leading to problems of inequity in water supply and unequal developmental outcomes. We also identify areas for future research and action on urban issues in the region.

Given the limited capacity of drainage systems in South Asian cities, urban flooding and waterlogging is expected to intensify. The problem gets worse with unplanned urban growth in low-lying areas and inadequate solid waste management. Using hydraulic models for two South Asian cities, Sylhet (Bangladesh) and Bharatpur (Nepal), we find that 22.3% of the land area in Sylhet and 12.7% in Bharatpur is under flooding risk. The flood risk area can be reduced to 3.6% in Sylhet and 5.5% in Bharatpur with structural interventions in the drainage system. However, this could increase to 18.5% in Sylhet and 7.6% in Bharatpur in five years without proper solid waste management, suggesting that the structural solution alone is almost ineffective in reducing long-term flooding risk.

In Tansen and Damauli municipalities in Nepal, the presence of user groups has indicated that proper management of water can help people avert critical water shortages. However, performances of these user groups vary. This paper delves into the community-managed water systems in the two cities and how the performance varies across them. In Tansen, infrastructural constraints and operational hazards associated with the supply systems present challenges. Moreover, there is large-scale corruption, allowing low-grade vendors to operate in place of readily available efficient institutions. In Damauli, the systems have been rather perfectly managed, except for minor, periodic glitches. Funding has been good and community bonding has paid off.
