The General Manager may utilize all reasonable means to identify properties with cross connections and may determine whether installation of backflow prevention devices is practicable and necessary in order to prevent the introduction of pollutants or contaminants to the Potable Water System.
In the event the General Manager determines that it is practicable and necessary to install backflow preventers, the General Manager shall give the Owner of the property identified written notification that the following will be required:
An Owner identified in a notice issued pursuant to § 5403.2 may petition the General Manager, in writing, for additional time to install the number and type of backflow preventers required by a notice issued pursuant to § 5403.2. This petition must be delivered to WASA no later than fifteen (15) days after the date of notice issued pursuant to § 5403.2. The General Manger may grant the request only upon a finding of good cause shown and shall advise the petitioning Owner of his or her decision in writing.
An Owner identified in a notice issued pursuant to § 5403.2 may also submit an alternative proposal to eliminate existing or potential cross connections. The Owner's proposal shall be in writing, certified by a professional engineer, registered with the District of Columbia, and must be delivered to WASA no later than fifteen (15) days after the date of the notice issued pursuant to § 5403.2.
The General Manager shall review the Owner's proposal made pursuant to § 5403.4, and after consideration of generally accepted engineering practices, in his or her sole discretion, either approve or deny, in whole or in part, the Owner's proposal in writing.
If the Owner's proposal made pursuant to § 5403.4 is approved in whole or in part, the General Manager shall notify the Owner to:
If the Owner's proposal made pursuant to § 5403.4 is denied, in whole or in part, the Owner shall install the devices required in the § 5403.2 notice within thirty (30) days from the date of the General Manager's denial.
An Owner, whose proposal made pursuant to § 5403.4 is denied in whole or in part, may also petition the General Manager for additional time to install the required devices. This petition must be delivered to WASA no later than fifteen (15) days after the date of the General Manager's notice of denial. The General Manger may grant or deny the Owner's request within the General Manager's sole discretion and shall advise the petitioning Owner of his or her decision in writing.
