A bill to authorize the International Boundary and Water Commission to accept funds for activities relating to wastewater treatment and flood control works, and for other purposes.

This bill (S 2034) authorizes the International Boundary and Water Commission (IBWC) to accept funds from federal or non-federal entities - like grants or agreements - for specific projects. It allows the IBWC to use these funds to study, design, construct, operate, or maintain wastewater treatment facilities, water conservation projects, or flood control works along the U.S.-Mexico border. Key limits include a $5 million annual cap on reimbursements to non-federal entities and restrictions on accepting funds from foreign entities designated as "of concern" or with agreements with such entities. The funds must be deposited into a specific Treasury account and reported annually to relevant congressional committees.
