If you have a fairly new septic system that’s in good condition, a city sewer hook-up might not bring you many benefits right now. But if your septic system is in need of extensive repairs or replacement, it might be time to reevaluate your situation. Keeping a septic system means you will have to maintain it, and you may be liable for any problems it could cause, such as groundwater contamination. If these things worry you, a city sewer hook-up may be worth considering.
