Sewllkwe is the Secwepemc word for water. Secwepemc is the indigenous language of founder Trever Andrew, a member of the Adam’s Lake Indian Band in British Columbia, Canada.  He has experienced first-hand how vital access to water quality data can be. 


As a water and wastewater operator, Trever also understands the hurdles and difficulties businesses and organizations face in recording, storing, managing, and communicating this information.  He has combined this knowledge and passion to provide meaningful and practical solutions that will benefit all.


Water management concerns everyone, whether they think about it every day or not. Proper water management ensures food security, prevents health-related issues, protects vital ecosystems, and ensures individuals, communities, cities, and regions can meet personal, household, and production needs.
