This minimum separation distances table is published in the State of Alaska’s 2017 Interim Guidance to Onsite Wastewater Systems Installation Manual and is the best table to depict all minimum separation distances in one location.
The Revised Total Coliform Rule requires that seasonal systems inspect, clean and sanitize their drinking water system prior to seasonally serving drinking water. A seasonal start-up inspection form is available at the Drinking Water Program website, and must be submitted within 10 days of serving water to the public.
We strongly recommend that you coordinate with your Environmental Program Specialist (EPS) at the Drinking Water Program prior to system startup. They will really appreciate a heads-up call.
As a courtesy, we are providing you a direct link to System Startup Forms, current as of March 2023
While this checklist was developed by EPA Region 8, rather than our Region 10, it is a very useful document for understanding the federal expectations for system described by the Revised Total Coliform Rule.
Disinfection Guidance
Even if your groundwater supplied Public Water System is not required to routinely add chlorine or otherwise disinfect your water, there are various times that you will either want to or be required to disinfect a portion, or all of your system.
The Drinking Water Program has provided some useful guidance documents for disinfecting small water systems
Performing Sanitary Surveys of Public Drinking Water Systems is a major component of Taiga Engineering’s business activities. A Sanitary Survey is required of federally defined Public Water Systems every 3 or 5 years. The survey consists of examining 8 components as outlined by the EPA
This is a useful mapping site maintained by the Drinking Water Program for identifying potential sources of contamination near your water source and just in general for getting aerial imagery of your site.
A wealth of information can be found by selecting a nearby SnoTel site on the map, and expanding the Data Reports tab to select the Site Page.
Operation of our water systems are very influenced by snowpack and snowmelt characteristics. Our easiest resource for seeing current and historical snow pack and snowmelt trends are the SnoTel site Snow Water Equivalent graphs maintained by the Natural Resources Conservation Service. 3 sites relevant for the Fairbanks Area include:
