Asia Pacific PPP Models In Water Infrastructure

Introduction

Asia Pacific’s water sector is seeing increased participation from private players through Public Private Partnership (PPP) models. As urban populations grow and government budgets tighten, PPP-led water supply and wastewater projects are being used to close funding gaps, introduce new technologies, and improve operational efficiency.

Countries including India, Indonesia, the Philippines, and Vietnam are now offering PPP frameworks for bulk water supply, desalination plants, STPs, and distribution upgrades. Several of these projects are backed by multilateral development banks and supported by climate financing.

Private Sector Involvement Is Expanding Across Multiple Water Segments

The PPP share in Asia’s water infrastructure spending is projected to grow at a CAGR of 8.1% from 2026 to 2035. India’s success with hybrid annuity models for STPs under the Namami Gange and AMRUT 2.0 programs has led to replication in Tier 2 cities.

The Philippine government's approval of the 10-year extension for Maynilad and Manila Water highlights the growing private sector involvement in water services, ensuring long-term investment and enhanced water security. Indonesia and Vietnam are now encouraging design-build-operate (DBO) and performance-linked contracts for new wastewater infrastructure.

Water treatment PPPs are gaining traction, as demonstrated by:

• SUEZ’s 2024 projects in Singapore, China, and the Philippines, focusing on desalination, water reuse, and digital solutions.
• In July 2024, Almar Water Solutions expands in the Asia-Pacific region through a partnership with Moya Indonesia.

Private players such as SUEZ, Veolia, VA Tech Wabag, Manila Water, and local EPCs are active across project stages from design and finance to long-term operations. Multilateral funding from ADB, World Bank, and climate finance mechanisms are further supporting viability gap funding and blended finance structures.
