HOUSTON (AP) — A Texas city that lost its drinking water system to Harvey struggled Saturday to restore service, and firefighters kept monitoring a crippled chemical plant that has twice been the scene of explosions and fires since the storm roared ashore and stalled over Texas more than a week ago. Officials in Beaumont, population almost 120,000, worked to repair their water treatment plant, which failed after the swollen Neches River inundated the main intake system and backup pumps failed.
