The Water Purification Industry in Vietnam: A Sustainable Future

Updated: Oct 19

Water is a precious resource and access to clean water is crucial for the health and well-being of people and the environment. Vietnam, like many other countries, faces challenges related to water quality and access. The country has made progress in increasing access to clean water, but there are still millions of households without access to safe drinking water. The water purification industry in Vietnam has an important role to play in addressing these challenges and ensuring a sustainable future.

Market Overview

According to a report by VietnamNet Bridge, the water purification market in Vietnam is estimated to reach US$9.3 billion by 2020. This growth is driven by the increasing awareness of the importance of clean water and the rising demand for water purification solutions. The market is highly competitive, with both domestic and foreign players vying for a share of the market.

The market can be segmented into residential, commercial, and industrial sectors. The residential sector is the largest segment, accounting for over 60% of the market. The commercial sector, which includes offices, hotels, and restaurants, is the second-largest segment, while the industrial sector is the smallest segment.

The water purification technologies used in Vietnam include Reverse Osmosis (RO), Ultrafiltration (UF), and Ion Exchange (IX). RO is the most common technology used, accounting for over 50% of the market. UF and IX are also used, but their market share is much smaller.

Market Problems

Despite the growth of the water purification market in Vietnam, there are still challenges that need to be addressed. The following are some of the key problems faced by the industry:

Water Quality

According to the Vietnam Environment Administration, only 38% of the country’s surface water sources meet the standards for domestic use. The rest are heavily polluted, making it difficult to obtain clean water for households and businesses. This poses a significant challenge for the water purification industry, which must rely on polluted water sources to produce clean water.

Water Waste

RO technology is widely used in Vietnam, but it generates a significant amount of water waste. According to the Ministry of Construction, only 50% to 70% of the water treated by RO can be used, while the rest is discharged as wastewater. This is not only wasteful but also poses environmental risks.

High Cost

The cost of water purification systems can be high, especially for larger systems used in the commercial and industrial sectors. This limits access to clean water for households and businesses with limited financial resources.

Low Penetration

Despite the growth of the water purification market, there are still millions of households without access to clean water. According to the General Statistics Office, only 52% of households in Vietnam have access to clean water. This highlights the need for more affordable and accessible water purification solutions.

Sustainable Solutions

The water purification industry in Vietnam has an important role to play in addressing the challenges related to water quality and access. Sustainable solutions are needed to ensure a long-term and environmentally friendly approach to water purification. The following are some examples of sustainable solutions being implemented in Vietnam:

Rainwater Harvesting

With a high amount of rainfall in Vietnam, rainwater harvesting is a sustainable solution for meeting water needs. It involves the collection and storage of rainwater for later use. It is a low-cost solution that can be implemented in both urban and rural areas. In Vietnam, the government is promoting the use of rainwater harvesting in rural areas to improve access to clean water.

Water Conservation

Water conservation is a sustainable solution that involves the efficient use and management of water resources. It includes measures such as fixing leaks, using water-efficient appliances and fixtures and practicing water-wise habits. The government of Vietnam is promoting water conservation as a way to reduce water waste and ensure that water resources are used efficiently.

CDI Technology

Capacitive Deionization (CDI) technology is a sustainable and cost-effective alternative to RO technology. CDI uses electrodes to remove impurities from water, resulting in a higher level of mineral maintenance and water recovery. CDI also generates less wastewater than RO, making it an environmentally friendly solution.

Vietdream, a company in Vietnam, is pioneering CDI technology and using it in their water purification systems. The company’s CDI filters have a high level of durability and can last up to 5 years. This makes them a more sustainable and cost-effective option for households and businesses.


The water purification industry in Vietnam is experiencing significant growth, driven by the increasing demand for clean water and the need for sustainable solutions to address the challenges related to water quality and access. The adoption of new technologies, such as CDI water purification technology, rainwater harvesting, and wastewater treatment and reuse, is contributing to the development of sustainable solutions that are more efficient and environmentally friendly.

Moreover, the trend towards environmentally friendly products is gaining momentum in the industry, reflecting the growing awareness and concern for the environment among consumers. As the industry continues to grow and evolve, there is a need for collaboration and innovation to ensure access to safe and clean water for all in a sustainable way.

Vietdream is a sustainable technology company in Vietnam that specializes in the development and production of CDI water purification technology. The company’s mission is to create products that are beneficial to human health and environmentally friendly while contributing to the development of science and technology in Vietnam. Vietdream’s products include general water purifiers, industrial water purifiers, and home-use water purifiers that have high levels of mineral maintenance, water recovery, and durability. The company aims to be the leading company in CDI water purification technology in Vietnam and to bring the best value to the health and life of the community.
