WATER
We ensure that an essential asset remains accessible and usable
The growing demand for clean water poses new challenges for communities and companies: how do facilities and conveyance systems keep pace? Our services for the water industry include water supply, water treatment and water distribution. Earth Tech provides a complete range of services to small, intermediate and large water suppliers, from source development, water treatment, storage and distribution, to operation and administrative services.
Water Supply
Clean water is the lifeblood of a community, but, according to the Water Partners International, more than 1.5 billion people do not have access to a safe and adequate water supply. Less than 1% of the world's fresh water (or about 0.007% of all water on earth) is readily accessible for direct human uses. This number could increase to 2.3 billion people by 2025.
Because the world’s fresh water supply is shrinking at an alarming rate, Earth Tech’s engineers and scientists are continually striving to develop technologies and products that will ensure a safe and reliable water supply for the world’s population. Desalinating seawater, for example, is thought to present one solution to the world's current and future water problems. At Earth Tech, we share the concern that the demand for water continues to exceed the available supply.
Understanding the various characteristics of the water source is key to determining how best to use this precious natural resource. The underlying principles we apply to water source development include promoting environmental responsibility, ensuring the development and maintenance of renewable water sources, locating sources with adequate quantity to meet user demands and providing a supply that meets or exceeds regulatory requirements.
Earth Tech evaluates each water source, and its impact on treatment, distribution and operations, providing a well-founded understanding of:
- Watershed and groundwater protection
- Watershed and well field capacity analysis
