A Minority owned, Woman owned, Veteran owned California based Limited Liability Company


WaterFunder, LLC accelerates the development of water infrastructure projects with project finance advisory and grant writing and management services.  

The benefits of water equity and water security are attainable for communities and companies.  


We craft strategic alliances and co-development partnerships that connect funding and financing solutions for small, rural, tribal and economically challenged communities specifically to accelerate the rebuild of resilient water infrastructure. Our alliance and partnership network allows us to easily customize corporate water stewardship and sustainability programs that satisfy declared ESG goals.

We pursue activities and relationships that get quick wins for a slow industry.


WaterFunder engagements support the financing needs of broadly defined water, sewer, storm, source water and green infrastructure projects.  We build alliances with investors and work with the stakeholders to accelerate the development process. We have assembled an experienced team of project finance, capital planning, asset management and development experts with experience in wastewater, drinking water, stormwater, source water and renewables. 

We focus on vulnerable communities and companies, and the ecosystems that supports them.


Small, rural, tribal, and economically disadvantaged communities are the most vulnerable to water inequities. Many US companies face extreme valuation losses from exposures to water insecurity risks. WaterFunder helps communities and companies implement innovative solutions that meet their aligned priorities.
