Water
Water is essential to manufacturers – whether for powering complex steam processes or use in simple domestic purposes. It is also a resource that has come under increasing risk in recent years, making it more imperative to reduce water waste. Recognizing this, more manufacturers are expanding their sustainability efforts to include water efficiency and conservation.
There are many challenges to implementing water efficiency measures at a manufacturing facility, such as poor ROIs on water efficiency projects and insufficient data on water use within the facility. However, understanding the true costs of water and assessing water efficiency opportunities can lead to substantial water and energy savings. Starting with basic good housekeeping practices and progressing to more advanced conservation strategies can help to establish a robust water management program.
Top Water Efficiency Measures
- Conduct a water balance
- Identify and fix leaks
- Consider water efficiency in the design and procurement of new systems
- Review equipment specifications and adjust water use accordingly
- Eliminate once-through-uses where possible, such as for cooling or cleaning

HARBEC’s Water Retention Pond is a key project supporting the company’s goal to be water neutral, which the company defines as eliminating the use of municipally supplied water for all purposes except drinking and hand washing. This goal will be achieved through a series of water efficiency measures, as well as utilization of the pond, which captures and stores rainwater for use in plant operations.
Nissan: Recylcing Water Using Advanced Filter Strategies
Since the start of production in 1983, Nissan’s Smyrna Vehicle Assembly Plant in Tennessee has built more than 11.5 million vehicles. The Smyrna plant’s paint engineers were searching for ways to reduce water consumption, which is a key part of the manufacturing process. Nissan ultimately invested in water filtration upgrades for four manufacturing systems.
United Technologies Corporation: Global Water Conservation Guidance Document
Water use has long been an important part of United Technology Corporation's (UTC’s) sustainability goals. The company is currently working toward a global target to reduce water use by 40% by end of 2015 and is in the process of setting a new water reduction goal out to 2020. To help meet its ambitious goals, UTC developed a comprehensive internal guidance document that details the company’s global water scarcity assessment, best practices in managing water at individual sites, and water saving case studies.
