Local Private Sector Involvement in Public–Private Partnerships for Sustainable Water and Sanitation in Asia

Abstract

Public-private partnerships (PPPs) are vital in water and sanitation sector projects, bridging the financial gap and addressing inefficiencies in public service provision. • PPP is a method, not a purpose itself. They should only operate if the local context is sufficiently prepared and if they are guaranteed to improve service delivery. • Success varies; not all local or municipal governments are equipped or interested in water and sanitation PPP projects, even in Japan. • Projects in developing Asia show the need for effective private sector collaboration and criteria development, given challenges such as inadequate regulatory frameworks and operating environments that impede long-term private investment. • This policy brief highlights the defining features of PPPs as an alternative to traditional public infrastructure procurement, improving the provision of local water and sanitation services across Asia.
