Hello, we have had a lagoon for probably 50 years at this house. When we built on to our house 10 years ago we had a bigger lagoon built. We have had smells come through the sink for probably 5 years and cannot get rid of it. 1 year ago we had a man come in, clean it out and re dig another hole. It still smells. What is wrong. Everyone we talk to has no idea! Help
