The water and wastewater facility construction loans are made through the State Revolving Fund, and can be used to finance planning, design and construction of water and wastewater facilities. The loans are administered through TDEC's Division of Community Assistance, which determines project funding through a need-based priority list. TDEC administers the State Revolving Fund program in conjunction with the Tennessee Local Development Authority.
