In 2025 the community of Tunshi San Javier (545 inhabitants, 69 children) still does not have sewarage. Connections are missing. The current solution for wastewater disposal consists of the use of septic tanks - per house and financed by each household. Each time a septic tank is full, family members empty it themselves or rent a tractor with their own means to dig a new space, or sporadically the municipality intervenes to empty the tank. Most households have the drain from the septic tanks connected to the roadside, which poses a growing health hazard to residents (including the children who cross the road to the local school every day). There is a treatment tank (built between 2021-2023, installed but not operational) which, once put into operation, will process the wastewater before sending it to the river.
