Tegucigalpa, the capital city of Honduras, is located in a central mountainous region having a tropical climate within the Choluteca River Basin. Major rivers supplying the capital city are the Choluteca and Guacerique rivers which then fill the Concepción and Laureles storage reservoirs. With an urban population of approximately 900,000 and another 400,000 living in the surrounding neighborhoods, Tegucigalpa is being confronted with an array of imposing integrated urban water management (IUWM) challenges. Potable water coverage is poor with around 40% of the city's residents without access to piped water supply thus relying on more costly water trucks and bottled water.
