What are the best Water and Utilities ETFs?

Looking to invest in the water and utilities sector? This article explores some of the top Water and Utilities Exchange-Traded Funds (ETFs) available in the market. Discover the potential investment opportunities in this sector and gain insights into the best ETFs for those interested in sustainable water and utility investments.

Water and Utilities ETFs: A Closer Look

Water and utilities are essential sectors in the global economy, providing vital services and resources to individuals, businesses, and communities. As an investor, you may be interested in gaining exposure to these sectors through exchange-traded funds (ETFs). ETFs offer a convenient and diversified way to invest in a specific industry or theme. In the case of water and utilities, several ETFs focus on companies involved in water supply, treatment, infrastructure development, and utility services.

One notable ETF in this space is the Invesco Water Resources ETF (PHO). This ETF seeks to track the performance of the NASDAQ OMX US Water Index, which includes companies involved in the water industry, such as water equipment and technology providers, utilities, and water infrastructure companies. PHO has a diversified portfolio of holdings, offering exposure to both large-cap and small-cap companies in the water sector.

Comparing PHO to other similar ETFs, the Invesco S&P Global Water Index ETF (CGW) is worth mentioning. CGW tracks the performance of the S&P Global Water Index and invests in companies from around the world that are involved in water-related businesses. While both PHO and CGW provide exposure to the water sector, their underlying indexes and holdings may differ, leading to variations in performance and portfolio composition.

Investing in Water and Utilities ETFs: Considerations

When evaluating water and utilities ETFs or any investment, it's important to consider a few key factors. First, assess the ETF's expense ratio, which represents the annual fee charged by the fund. Lower expense ratios are generally more favorable for investors, as they result in lower costs and higher potential returns.

Additionally, examine the ETF's liquidity and trading volume. Higher liquidity ensures that you can easily buy or sell shares without significantly impacting the market price. Look for ETFs with adequate trading volume and tight bid-ask spreads to avoid unnecessary costs and delays.

Furthermore, review the ETF's holdings and diversification. A well-diversified ETF will spread its investments across multiple companies, reducing the impact of individual stock price movements on the overall portfolio. Consider the composition of the ETF's holdings, including the allocation to large-cap versus small-cap companies and the geographic distribution.

Factors Driving the Water and Utilities Sector

Several factors contribute to the growth and development of the water and utilities sector. Increasing global population, urbanization, and industrialization create a rising demand for clean water and efficient utility services. Additionally, the need for infrastructure improvements and investments in water treatment and distribution systems further drive the sector's growth potential.

Moreover, increasing environmental awareness and sustainability concerns propel the adoption of innovative technologies and solutions in the water industry. Companies involved in water purification, wastewater management, and sustainable water infrastructure may benefit from these trends.

The Future Outlook for Water and Utilities ETFs

Water and utilities are expected to remain crucial sectors for long-term economic and social development. As governments and societies prioritize water resource management and infrastructure upgrades, investments in water and utility companies may present opportunities for growth and potential returns.

However, it's important to note that investing in ETFs involves market risks, including the possibility of loss of capital. It's advisable to conduct thorough research, assess your risk tolerance, and consult with a financial advisor before making any investment decisions.


Investing in water and utilities ETFs allows you to gain exposure to the vital sectors that provide essential resources and services. The Invesco Water Resources ETF (PHO) is one example of an ETF focused on the water sector, while the Invesco S&P Global Water Index ETF (CGW) provides exposure to water-related businesses worldwide. As with any investment, carefully consider factors such as expense ratios, liquidity, diversification, and the drivers behind the water and utilities sector. Always conduct thorough research and consider seeking professional advice before making any investment decisions.
