Phnom Penh Water Supply Authority (PPWSA)

What Phnom Penh Water Supply Authority (PPWSA) does

Phnom Penh Water Supply Authority (PPWSA) is a Cambodian state-owned water utility, established in 1999 and operating under the Royal Government of Cambodia, that provides potable water production, treatment, distribution, and customer-billing services across Phnom Penh and surrounding areas. The company is publicly listed on the Cambodia Securities Exchange under ticker PPWSA, distributes annual dividends (330 KHR per share for FY2025), and is governed by a Board of Directors chaired by Deputy Prime Minister Ek Sarun. PPWSA serves over two million residents through three core operational pillars: water production systems (intake, treatment, and processing), a pipe-network distribution system with SCADA-based monitoring, and customer-facing service modules including metering, billing, house connections, and e-payment. The utility also runs subsidized programs for low-income households and engages in community development.

PPWSA generates revenue primarily through regulated water tariffs billed on consumption volume, household connection fees, and related service charges, producing FY2025 revenue of 373.28 billion KHR (up 7.36% year-over-year) and operating profit of 130.71 billion KHR, an operating margin of roughly 35%. The business is capital-intensive and reliant on concessional development financing: the Bakheng Water Supply Project Phase 3 alone has attracted approximately €198 million from AFD (€100M), EIB (€85M), and the EU (€13M), with French engineering and construction partners including Safege/Suez, Vinci Construction Grands Projets, Saint-Gobain, and Bayard delivering the infrastructure. Customer segments are horizontal — residential households, commercial and industrial users, and a subsidized low-income population — with no individual customer concentration risk due to the household-by-household distribution model.

Core offering

PPWSA provides end-to-end municipal potable water services — abstraction, treatment, quality management, and distribution through pipe networks — to residential, commercial, and industrial customers in Phnom Penh and surrounding areas, supported by household connections, metering, billing, and customer service operations.

Product overview

PPWSA operates a unified water utility infrastructure providing end-to-end water supply services. The core portfolio consists of water production systems (intake, treatment, processing), water distribution networks, and quality management, supplemented by customer-facing service modules including billing, meter management, house connections, and e-payment options. The organization also operates social programs for low-income communities and provides training services. The product architecture is a single integrated utility system rather than a modular software platform, with water purification systems also donated to external organizations as part of corporate social responsibility.

Direct peers

• Manila Water Company: Philippine-listed water utility operating the Metropolitan Waterworks and Sewerage System concession for the eastern Metro Manila zone. Highly comparable to PPWSA: both are publicly listed, regulated urban water utilities in Southeast Asia serving millions of residential customers via metered distribution networks, with similar concession-based business models.
• SAJ Holdings (Ranhill SAJ): Malaysian state-owned water treatment and distribution company operating in Johor. Closest structural peer to PPWSA: state-linked, ASEAN-based, regulated municipal water utility serving a defined geographic concession area with a mix of residential, commercial, and industrial customers.

Broad incumbents

• Suez SA: Global French water and waste management utility that operates municipal water concessions worldwide and serves as the parent of Safege Consulting, an active technical partner of PPWSA on the Bakheng project. Comparable in that both operate regulated water supply and treatment infrastructure, though Suez operates at vastly greater scale and geographic breadth.
• American Water Works Company: Largest publicly traded US water and wastewater utility, serving over 14 million people across 14 states through regulated rate-based operations. Comparable to PPWSA in business model (regulated utility providing water service via owned networks) though materially larger and operating in a developed-market regulatory framework.
• Beijing Enterprises Water Group: Hong Kong-listed water and environmental services company with extensive water supply, sewage treatment, and construction operations across China and internationally. Comparable as a large-scale water utility with integrated treatment, distribution, and project execution capabilities similar to what PPWSA is developing in Cambodia.
• Veolia Environnement: One of the world's largest water and environmental services groups, operating municipal water concessions across multiple continents. Veolia is comparable to PPWSA as a regulated water utility operator with a focus on treatment, distribution, and customer service for residential and industrial users.

Emerging players

• Essential Utilities Inc. US natural gas and water utility serving customers across multiple states, with a regulated water segment covering treatment and distribution. Comparable as a publicly listed water utility with regulated rate structures and recurring metered revenue, though operating at much larger scale and in a developed-market environment.
• Ranhill Utilities Berhad: Malaysian water treatment and power group with operations in Johor and broader Southeast Asia. Comparable to PPWSA as an ASEAN water utility with both treatment operations and broader infrastructure interests, though Ranhill operates a smaller customer base and more diversified service portfolio.
• Guangdong Investment Limited: Hong Kong-listed company whose principal subsidiary operates the Dongshen Water Supply System supplying raw and treated water to Hong Kong and Guangdong. Comparable to PPWSA as a large-scale regional water supplier with cross-border water infrastructure serving dense urban populations.

Regional players

• Cay Saign (Saigon Water): Saigon Water Supply Corporation (SAWACO), the state-owned water utility serving Ho Chi Minh City, Vietnam. Closely comparable to PPWSA in structure: Southeast Asian state-owned, publicly listed, urban water utility providing potable water to millions of metropolitan customers under government oversight.
