Regarding the City of Houston’s water and sewer service, I have found this, posted today:

As of Monday, September 15, 2008 we are diligently working with CenterPoint Energy to restore power to sanitary sewer pumping stations that carry waste water to our treatment plants. Currently PWE crews are performing physical inspections and evaluating the condition of wastewater lift stations and treatment plants throughout the city. Only 10 of the 40 wastewater facilities and 15 out of 400 lift stations scattered throughout the city, are fully operational. We have prioritized repairs to the remaining facilities starting with the ones that service the largest populations. Crew will be working vigorously to get the remaining repairs completed as soon as possible. We are aware of the inconvenience caused by Hurricane Ike and encourage the public to call 3-1-1 to report sewage problems within their neighborhoods. These problems are directly related to high flood storm water that invaded our sanitary sewer systems. As the floodwaters decrease all across our communities, the sanitary sewer problems will diminish.

According to the latest information available on Ch. 13 (broadcast, no link yet), the boil advisory has been lifted, except for east of 288, south of Hwy 90, out to Beltway 8.
