Projects aim to improve water efficiency and conservation in agriculture, business, and more
July 24, 2025
Michiganders know careful stewardship is crucial to sustaining water – our most precious natural resource.
Even in a water-rich state like ours, water efficiency and conservation are essential to protecting rivers, lakes, streams, and underground aquifers. They reduce demand for water withdrawals – lowering customers’ water bills and saving energy consumption and greenhouse gas emissions required to transport water long distances – and limit runoff that can pollute local water bodies.
Healthy waterways support thriving fish and wildlife, supply safe drinking water for communities, and fuel Michigan’s water-based blue economy.
Among water conservation and efficiency efforts underway in Michigan are a project through the nonprofit Alliance for Water Efficiency (AWE) to explore water conservation best practices and another focused on helping agricultural growers adapt to climate change.
Water-saving best practices
The Office of the Great Lakes in Michigan’s Department of Environment, Great Lakes, and Energy (EGLE) awarded AWE a grant of $89,648 to identify innovations and technological advancements in water conservation practices.
This project will summarize sectors’ existing processes and best management practices, or BMPs, with a focus on business and industry. The team will also collect information and research water sectors implementing innovative and advanced water conservation BMPs across the region and broader U.S. to inform Michigan’s WCEP.
Throughout 2024 and early 2025, AWE conducted interviews and convened a work group to understand commercial and industrial water conservation in Michigan. A final report is expected this year.
Water conservation in agriculture
Michigan has one of the nation’s most diverse agriculture economies with available fresh water and is one of Michigan’s largest water users. Several efforts support sustainable water use in agriculture and agribusiness.
The sector is significant as both a user of water and an implementer of new water efficiency technology and management practices.
A partnership among the Michigan Plant Coalition, the Michigan Department of Agriculture and Rural Development (MDARD), and Michigan State University (MSU) is helping agricultural growers adapt to climate change while protecting and efficiently using state water resources.
The Agricultural Climate Resiliency Program was established with a one-time $5 million investment for a competitive grants program and $1 million a year through the MDARD budget to support six new faculty positions and two MSU Extension educators. It’s administered by MSU Extension and MSU AgBioResearch.
MSU Extension also hired two agriculture water use efficiency and irrigation educators through a contract with EGLE and MDARD. The goal is to provide local and statewide leadership and teach efficient irrigation management for crop production as well as efficient water management for raising animals.
Irrigation schedules and sensors
Several collaborations underway with MSU Irrigation Lab and agricultural industry partners, including commodity organizations, involve field days, demonstration projects, and research. Most of the irrigation projects focus on improving water use efficiency through scheduling methods and sensor technology.
Field tests for automated smart irrigation systems and upgraded sprinkler packages on center-pivot irrigation systems show significant efficiency improvements. One MSU irrigation lab demonstration study in a commercial corn and soybean field found that smart irrigation sensor technology saved water while maintaining the same and/or higher yield as before.
While 1.9 inches of water saved in the cornfield and two inches saved in the soybean field may sound modest, scaling up the technology across Michigan’s irrigated corn and soybean acreage could save up to 29 billion gallons of fresh water.
