Utility Conservation


Houston’s water and wastewater systems are experiencing low pressure. To help maintain water pressure in the system during this winter weather event, please use water only for essential tasks and help conserve water by not running washing machines, dishwashers, or watering outdoors.

Once temperatures rise above freezing and power is restored, these are the best ways to thaw frozen water pipes:

  • Open cabinet doors to circulate heat
  • Use hair dryers, heat lamps or portable space heaters
  • DO NOT USE open flames and/or propane torches (fire hazard)

Continue to conserve water after pipes have thawed.


Houstonians among with all of Texas are experiencing power outages. Houston OEM is urging everyone to conserve as much energy as possible. Power outages are expected to continue throughout Monday and Tuesday.

Conserve energy by:

  • Turn off and unplug non-essential lights and appliances; and avoid using large appliances (e.g. ovens, washing machines, etc.).
  • Turn down thermostats to 68 degrees or lower
  • Open blinds and shades to take advantage of the sun's natural heat during the day
  • Close shades and blinds at night to reduce the amount of heat lost through windows.

We urge all residents to conserve resources such as electricity and water.

During ERCOT rotating outages this is what you can expect:

  • Depending on the severity of the power generation shortfall, rotating outages may impact customers more than once.
  • CenterPoint Energy will continue these rotating outages until it receives direction from ERCOT that the electric supply in Texas has stabilized and can resume normal operations.

Staying Warm When the Power is Out

Safely Use Space Heaters

Heating devices cause more than 100 fires in the City of Houston each year, resulting in numerous injuries and possible death. Citizens should always keep in mind that: Space Heaters Need Space!

The Houston Fire Department recommends the following safety tips when using supplemental heating sources:

  • Make sure you have a working smoke alarm.
  • Never leave children unattended in a room with a space heater – Children knock over space heaters, especially if they are placed on top of wobbly tables or stools and near where the children play. Children may also stick paper or toys in the grates of the space heaters especially gas space heaters. The city had two reported fires in 2004 caused by children playing with space heaters.
  • Keep all combustible materials, including yourself, at least three feet from the heater.
  • Open face heaters should have a screen.
  • Provide ventilation to prevent carbon monoxide poisoning.

Electric Heaters Tips

  • Never overload outlets or breakers.
  • Don’t use extension cords for the heater. If the cord is hot to the touch, turn off the heater and unplug it!
  • Electric heaters permanently installed in the wall or ceiling should have lint and dust removed regularly. Lint and dust will burn!

Avoid Carbon Monoxide Poisoning

Carbon monoxide (CO) is an odorless, colorless gas that kills without warning. It claims the lives of hundreds of people every year and makes thousands more ill. Many household items including gas- and oil-burning furnaces, portable generators, and charcoal grills produce this poison gas. Following these important steps can keep your family safe.

CO Detectors

  • Install battery-operated or battery back-up CO detectors near every sleeping area in your home.
  • Check CO detectors regularly to be sure they are functioning properly.

Oil & Gas Furnaces

  • Have your furnace inspected every year.

Portable Generators

  • Never use a generator inside your home or garage, even if doors and
    windows are open.
  • Only use generators outside, more than 20 feet away from your home, doors, and windows.

Visit CDC's webiste for more information on Carbon Monoxide.

Protective Measures

The 4 Winter Weather P’s


  • People should wear layers of clothing to stay warm. Gloves and a hat will help prevent losing your body heat. 
  • Stay inside and off the roads as much as possible when temperatures drop.  
  • Check on family, friends, and neighbors who may be susceptible to this week’s cold weather and/or not have access to housing and heating, including the elderly and those with access and functional needs. 
  • Avoid overexertion, as cold weather puts added strain on your body. 
  • The Coalition for the Homeless coordinates information for partner agencies and the general public and maintains an updated list of those resources for individuals who may be experiencing homelessness: 


  • Pets should be brought indoors and provided with a warm place to sleep. 
  • Pets, like humans, are vulnerable to cold temperatures. If not taken care of properly, they can succumb to frostbite and even hypothermia.  
  • Normal water supplies will likely freeze over including stock ponds and lakes. 
  • If your pet looks like it has any symptoms resembling frostbite or hypothermia, call your vet. 


  • Pipes that run outside or under a house should be wrapped in pipe insulation to avoid cracks due to water freezing in them. 
  • Pipes that are in areas that do not have proper insulation, such as basements or attics, may need extra insulation to keep from freezing. 
  • You can also cover your pipes with towels, duct tape or another adhesive strip as long as they are wrapped tightly. 
  • Do NOT drip your faucets, this will cause low water pressure to our City. Instead, you can open cabinet doors under sinks to make sure they stay warm.  
  • In some cases, the best course of action may be to shut off water to a structure and drain pipes overnight when water usage is low to avoid pipes freezing and bursting. 


  • Plants may need to be covered or brought inside to avoid frost damage. 
  • When wrapping outdoor plants, use a breathable material such as a cloth, blanket, or old sheet.  
  • Be sure to group plants that are in containers together, and near your home if moving them inside is not an option.  
  • Remember that soil in containers can get just as cold as the air temperature and cause the roots to freeze.
