The Authority shall not entertain any application from any residential
or industrial waste discharger that seeks to construct sanitary sewer
improvements which will connect or discharge into the Authority's
collection system unless the Authority receives with said application
a letter from the Delanco Township Tax Collector certifying that the
real property taxes for the property in question are current at the
time said application is made. Furthermore, no application will be
accepted by the Authority until all escrow payments established by
the Authority's Secretary/Treasurer and consulting engineer have
been established and paid on account for said residential or industrial
waste applicant.
