Engineering Support and Plan Review

The Department of Environmental Conservation is working on updating our file structure for onsite wastewater systems. Paper records from Wasilla and Juneau are being sent out for digital scanning. Files are still available, but retrieval of needed records may take up to two weeks. For more information, please contact Terri Lomax at 907-269-7635 or terri.lomax@alaska.gov.

Onsite Disposal Systems

Onsite disposal systems (OSDS), called septic systems, are widely used in Alaska. Proper installation and care of these onsite systems by homeowners and contractors is essential to maintaining the health of the system, public health and Alaska's environment. This program provides training for proper installation of conventional OSDS.

In areas with difficult site conditions, poor soil or high groundwater conditions that can't support a conventional system an alternative OSDS may be needed. In some instances a waiver may be required. These systems must be designed by an engineer and plans must be reviewed and approved by the Alaska Department of Environmental Conservation prior to construction.
