All customers of properties using reclaimed water as an auxiliary source of water
supply shall install an appropriate backflow preventer, as listed in Section 32-154(c) on the potable water service connection, immediately adjacent to the water meter
serving the property. Existing customers must effect this installation before December

appropriate backflow preventer, as listed in Section 32-154(c), as a condition to permitting, issuance of a certificate of occupancy, and installation
of a water meter. The Department shall set forth specific limitations and requirements,
in accordance with all rules and regulations promulgated by State agencies, in each
customer agreement for use of reclaimed water. No reclaimed water shall be provided
by the Department except under terms of an agreement with the customer.
