Water conservation and management is becoming a worldwide survival issue due to accelerating water shortages, property development and population growth, aging infrastructures, growing agricultural demands, a general warming trend, and the ever-increasing cost of and demand for natural water resources.

RMS brings a commonsense, cost-effective approach to addressing the escalating issue of water conservation and management through its innovative rainwater harvesting system designs and its experienced, knowledgeable staff. The expertise of the staff encompasses industries directly impacted by water management issues.

David Crawford, CEO and founder of RMS, worked in the health field for years and knew that large commercial laundries could use 50,000 gallons or more of water daily to clean hospital linens. Observing this and other examples of the growing use of drinking water in commercial and residential sectors, Dave became a strong advocate of water conservation and management. His advocacy led him to begin researching methods for conserving drinking water and utilizing the availability of rainwater. Thus was formed the concept of a business that would focus on rainwater harvesting and sustainable water management practices.

Using empty laundry soap barrels, Dave created a prototype rain barrel for rainwater collection. After 50 or more tries, he succeeded in creating a system that worked. He advertised the system at a home show and as a result, sold several residential home systems.

In 2001, David's brother, Ed, joined the company as Vice President of Operations. Ed Crawford has been a public safety advocate for over 21 years, eight of which were spent lobbying on public safety issues at the federal and state level.

RMS has since evolved from the rain barrel days to the company it is today. RMS provides professional services to organizations and individuals who are involved in water conservation, sustainable water management and green building standards in their projects.

RMS executives are lecturers at universities and colleges, encouraging architecture and engineering graduates to transition from theory to application and design of effective rainwater systems. RMS also sponsors workshops and programs that award LEED Continuing Education Units.
