HB2098 county water augmentation authorities; bond

Expands the powers of county water augmentation authorities by broadening the definition of authorized projects to include water conservation, water acquisition, and loans of bond proceeds to operating units. Authorizes an authority to issue revenue bonds to finance projects, establishes detailed bonding, security, and lien provisions, and exempts the bonds and bond income from state and local taxation. Requires advance notification to the Attorney General before bond issuance and bars legal challenges after 30 days once issuance is authorized. Authorizes an authority to construct or improve wastewater and drinking water facilities using loans or forgivable financial assistance from the Water Infrastructure Finance Authority of Arizona and to enter into loan repayment agreements funded by authorized revenues.
