Question: Why is water flooding into the basement?
Answer: During the attack on the compound while the baby is being delivered one of the creatures breaks a water pipe and it begins flooding into the basement.
Answer: That's essentially what the family is trying to do. They come up for supplies and to use the radio to try and reach the outside world. They built the basement area and used what supplies they had for soundproofing.
