Proposal of a low-cost water supply solution for Northern mountainous area of Vietnam

Abstract

Clean water scarcity is an increasingly urgent issue amid the escalating global climate change. This challenge is particularly prevalent in remote and mountainous regions, as well as island territories. Access to clean water in the Northern Mountainous Region of Vietnam has been steadily diminishing in recent years due to both challenging natural conditions and deteriorating water supply infrastructure. Therefore, this study conducted a survey on water supply demand and proposed low-cost water supply and sanitation solutions for mountainous areas in Vietnam. The two potential water sources were from rainwater harvesting and water from air condensation, which have provided enough drinking water for students in the studied school in Ha Giang province.

Keywords: Water scarcity; climate change; Northern mountainous areas; low-cost solutions.
