Malaysia has greatly improved its basic water and sanitation infrastructure over the past few decades. Nearly 100% of Malaysia’s rural and urban populations have at least some access to basic sanitation services. Much of this growth has been prompted by quick economic growth and an expanding tourism industry. But, Malaysia’s WASH systems are not without flaws. Industrialization and climate change have increased water pollution and threatened vital utility infrastructure, making it difficult for some residents to routinely obtain clean water and sanitation services. Additionally, members of marginalized groups like the indigenous Orang Asli face discrimination from officials, leaving accessibility gaps for vulnerable groups who try to obtain WASH services.
