Non-conventional systems, such as mounds and treatment units, must have engineered plans submitted to the ADEC by an engineer (P.E.) licensed in Alaska and must be approved before construction, modification or installation. Any system that receives non-domestic waste must complete plan review process also. Written approval is not required for an emergency repair or routine maintenance, however, contact with the ADEC must be made prior to emergency repair. Upon completion of construction, modification, installation or emergency repair, record drawings must be submitted to ADEC by a licensed engineer.
The review, construction and approval process is as follows:
- Step One - obtain Approval to Construct from ADEC for system installation, modification or repair
Engineer is hired by property owner to design and prepare plan submittal. Plans are then submitted for review by ADEC engineer for compliance with ADEC 18 AAC 72 wastewater regulations. Approval to Construct is granted once plan review is completed. The Approval to Construct will include conditions for approval and typically grants a two year time period to complete construction.
- Step Two - system is constructed
The system is constructed according to plans reviewed and approved by ADEC. During the construction, the designing engineer will inspect and document the installation. The use of a certified installer is not required but is recommended.
- Step Three - obtain Approval to Operate
Following construction, the designing engineer will submit the Certification of Construction form, record drawings if required, any condition verifications and, if required, a copy of the maintenance agreement between property owner and a qualified service company. The submittal is then reviewed for compliance with ADEC wastewater regulations and Approval to Operate from ADEC is issued for the new or modified system.
