Sister Larraine Lauter OSU serves as co-founder and current executive director of Water With Blessings, an ecumenical US-based 501(c)(3) with a mission of "clean water for God's thirsty children", and a flagship program in which mothers have been equipped, empowered and entrusted to serve their communities as "Water Women" since 2008. This program combines Sawyer PointOne hollow fiber technology with an award-winning service program (PAHO Foundation 2014 Award of Excellence) which solves the most persistent challenges of sustainability, uptake and scale in a way that yields remarkable impact (virtually total, long-range elimination of childhood diarrhea) as verified by GIS data. The program is especially noteworthy for long-term sustainability and impact in the most remote communities, where ensuring that every household has access to clean water means immediate improvements in community health outcomes.  The Water Women movement has grown exponentially since the first 10 Honduran mothers in 2008, to over 145,000 to date in 48 countries. By including the original Honduran recipients and local leaders in the program design process, Sister Larraine arrived at a service-model program which draws on the great untapped resource for sustainable development: mothers.

Sister Larraine's previous service experience includes the fields of education and pastoral ministry, as well as music.
