PORTLAND — The Environmental Protection Agency is issuing tips to Maine homeowners on how to avoid septic system problems during the holiday season.

Maine has the second highest percentage of septic ownership in the country, with nearly half of all homes using individual septic systems.

The EPA says many of those systems become overwhelmed during the holiday season with parties, get-togethers and out-of-town guests.

The agency says homeowners should maintain their systems, make clear to guests what should not be flushed and make sure cars and heavy equipment are kept off drainage fields.

More information can be found on the EPA’s web site.
