Bolivia's Viacha municipality in La Paz department will invest US$3mn to build a wastewater treatment plant, newspaper El Diario reported.
The World Bank will finance the project.
The plant will treat sewage that is currently being disposed of untreated into the Cohana bay which then leads to the Titicaca lake.
Viacha generates 5% of the wastewater that enters Cohana bay.
Construction is scheduled to begin in 1Q10.
Construction of the wastewater treatment plant in Puchukollo is slowly moving forward, local paper El Diario reported.
The plant will treat sewage from the city of El Alto, located northwest of capital La Paz, and will reduce the contamination in the Katari river and Titicaca lake.
The initiative requires an investment of approximately 53.0mn bolivianos (US$7.55mn), which is being financed by the national government (88%) and by El Alto's local government (12%), according to the country's environment and water ministry Minagua.
The Puchukollo plant will directly benefit 630,000 people.
The town of San José de Chiquitos in Santa Cruz department inaugurated a new water pumping system which will guarantee supply 24 hours a day, news website El Deber Digital reported.
Due to climate change, the local Sutó river has been drying up causing problems with water supply, the report said.
The Pororó system gets water from underground sources and was installed 21 km from San José. The system is providing 800,000l/day.
However, San José's mayor Germaín Caballero said that due to the growing population, the system is only a partial solution.
"The definitive solution to the water problem is the construction of a reservoir near San José," Caballero said.
