The ruling on water in the street that comes out of houses

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling on the water that is in the street, which comes out of the houses, considering that sometimes it may have been mixed with something from the sanitary sewage overflowing from the septic tanks?

Answer:
The default ruling for it is purity, my brother, and do not go to extremes unless you know that it is impure. If you know that it is impure, avoid it and wash whatever it has touched. But if you do not know, the default ruling for it is purity. The mud of the street and the water of the street, the default ruling for them is purity unless you know that it is impure. Do not be severe with yourself or with people. The Prophet (peace and blessings be upon him) forbade being severe. The default ruling is purity, and praise be to Allah. Yes.
And when a man in the company of 'Umar asked about water that had come out of a house, he said: "O owner of the house, ask him about the water for us." 'Umar said to him: "Do not tell him, we were not commanded to do this," or as he said (may Allah be pleased with him).
