Phnom Penh Water Supply Authority

Phnom Penh Water Supply Authority (PPWSA)

Phnom Penh Water Supply Authority (PPWSA) is the public water utility responsible for providing potable water to the residents of Phnom Penh, the capital city of Cambodia. The authority is known for its significant improvements in water supply services and infrastructure over the past few decades.

History

The Phnom Penh Water Supply Authority was established in 1959. During the Khmer Rouge regime from 1975 to 1979, the water supply infrastructure was severely damaged. After the fall of the Khmer Rouge, the PPWSA faced numerous challenges in rebuilding and modernizing the water supply system.

In the 1990s, under the leadership of Ek Sonn Chan, the PPWSA underwent major reforms. These reforms included reducing water losses, improving billing systems, and expanding the water supply network. The authority's efforts have been recognized internationally, and it has received several awards for its achievements.

Operations

The PPWSA operates several water treatment plants and an extensive distribution network. The main sources of water are the Mekong River and the Tonle Sap River. The authority ensures that the water meets national and international quality standards before it is distributed to consumers.

Water Treatment

The water treatment process involves several stages, including coagulation, sedimentation, filtration, and disinfection. The PPWSA uses modern technology and equipment to ensure the efficiency and effectiveness of the treatment process.

Distribution Network

The distribution network of the PPWSA covers the entire city of Phnom Penh and its surrounding areas. The network includes a combination of pipelines, pumping stations, and storage reservoirs. The authority continuously monitors and maintains the network to prevent leaks and ensure a reliable water supply.

Achievements

The PPWSA has been recognized for its successful turnaround and efficient management. Some of its notable achievements include:

• Reducing non-revenue water from over 70% in the 1990s to less than 10% in recent years.
• Expanding access to clean water to over 90% of Phnom Penh's population.
• Implementing a computerized billing system to improve revenue collection.

Challenges

Despite its successes, the PPWSA faces ongoing challenges, including:

• Meeting the growing demand for water due to rapid urbanization.
• Ensuring the sustainability of water resources in the face of climate change.
• Continuing to improve infrastructure and services to maintain high standards.

Future Plans

The PPWSA has outlined several future plans to address these challenges, including:

• Expanding the water treatment capacity by constructing new treatment plants.
• Upgrading the existing distribution network to reduce water losses further.
• Implementing advanced technologies for better water management and conservation.
