Flood Control.

§ 18-29-716.1 Flood control devices.

Flood control devices in any house drain shall be vented and sized in accordance with this chapter. The total fixture units and any continuous or semicontinuous flow shall determine the size of the vent. No vent shall be less than 2 inches (50 mm) in diameter.

§ 18-29-716.2 Flood control systems.

Flood control systems may be installed as necessary with the approval of the commissioner of sewers. Ground floor plumbing fixtures may discharge into the building sewage ejector, in areas experiencing sewer backup only when all downspouts or other storm drainage is discharging downstream of the backwater valve or when the downspouts are not connected to the sewer system.
