All new construction and substantial improvements shall be constructed using methods and practices that minimize flood damage.
C. 
Utilities.
(1) 
All new and replacement water supply systems shall be designed to minimize or eliminate the infiltration of floodwaters into the systems;
(2) 
New and replacement sanitary sewage systems shall be designed to minimize or eliminate the infiltration of floodwaters into the systems and discharge from the systems into floodwaters;
(3) 
On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding; and

Manufactured homes.
(1) 
Manufactured homes shall be anchored in accordance with § 222-16A(2).
