Location
TX, FORT BEND
Narrative
At 3:54pm centerpoint energy was notified of a housefire at 15818 camino del sol. Centerpoint arrived at 4:04pm. Based on signs of previous construction activity in the rear easement, it is believed that improper construction practices by unknown/unidentified parties resulted in loss of support under the 1 1/4 inch poly main. This loss of support placed stress at a socket fusion coupling on the main, allowing gas to escape and migrate through the soil into structure, resulting in fire/explosion by unknown/undetermined ignition source.
