Hackney plumbing

Humm, not sure which is worse, contaminating all of the soil which might be hard to scrape off along with all of the landscaping, or pumping out the basement, whose hard surfaces probably could be sanitized. Neither choice seems ideal! Glad I've never lived in a place where that was a regular event. For our sewers to back up from an overflowing main, would be almost impossible as we're about 40' above the road where the sewer line runs, and near a high point for the roadway as well.
Its better to have it overflowing OUTSIDE.
