Based on the recommendations of the qualified wastewater engineer, said city or town may approve, modify, or reject the contractors proposed plans and specifications. Any contract awarded pursuant to this act shall provide that, in the event that said city or town does not approve the contractor’s proposed plans and specifications pursuant to this section, said city or town or the contractor may terminate the contract under the terms and conditions of such contract.
