The special fund is set apart for the payment of the refunding bonds and cannot be used for any other purpose. All sums collected from such special assessments shall be placed in the special fund and shall be used for no other purpose than payment of the principal of and interest on the refunding bonds.

For the assessment or reassessment, collection and payment of the special assessments, the full faith and diligence of the city or town are irrevocably pledged.
