ADEC – Classifying Water and Wastewater Systems

When designing a new water treatment / distribution or wastewater treatment / collection system it is important to understand the certification level the operator will need to have to operate the system. The Alaska Department of Environmental Conservation (ADEC) has but together a few worksheets to help engineers determine the classification level of the system they are designing. It is recommended to reach out to ADEC to review the filled out worksheets and confirm the official system classification.

ADEC – Sewage Lagoon Closure Plan Requirements

When planning for the future closure of a Sewage Lagoon it is important to review the Alaska Department of Environmental Conservation’s (ADEC) requirements.

ADEC – Lagoon Construction Guidelines

In 2009 the Alaska Department of Environmental Conservation (ADEC) released “Lagoon Construction Guidelines”. These guidelines were developed to provide an avenue for consistency Lagoon Construction & design reviews. The ADEC realizes that these construction guidelines may not work in every situation so “if a plan uses alternative methods to determine the basis of design for a lagoon, a thorough explanation of the supporting data will be required”
