Water Restrictions

While water supplies and pressure are sufficient to meet current needs, Mayor Johnny Isbell has announced that the City of Pasadena has now implemented Stage II water conservation measures as a precautionary move to help minimize the chance of tighter water restrictions down the road.

Water Plant

Acting upon the recommendation of Public Works Director Robin Green, Isbell is harmonizing Pasadena’s water conservation measures with those of the region, as a record-breaking drought devastates just about all of Texas. The balance was tipped when Houston acknowledged pressure issues in their system which feeds our community’s supply, much of that due to water main leaks and breaks. At the same time, Houston announced it was tapping into Lake Conroe to try to make up for the lower volume they are experiencing with their normal water sources, such as Lake Houston.

“Pasadena residents responded recently when we first asked for voluntary conservation,” Isbell said. “We had hoped to avoid a further tightening, but with no sustained rainfall since that time, it’s prudent to bring our efforts in line with our neighbors, and so I’ve just announced the Stage II level of conservation.”

Water Demand Watch

Stage II is known as Water Demand Watch, and is triggered when total water use from all sources exceeds 90% of current capacity for five consecutive days. While Pasadena's use is just short of that metric, it was decided to move forward with the tighter restrictions now as a proactive move. Its goal is a 15% reduction in overall water demand, with an emphasis on across the board elimination of wasteful water use rather than limiting normal household (excluding outdoor use) and necessary commercial consumption.

The complete Stage II conservation information (PDF) is available, but there are priority actions you should be aware of immediately. Please keep in mind there are some suggested measures that would be very helpful to the community if followed, but are marked as voluntary compliance. Those activities designated as mandatory, on the other hand, must be complied with immediately to avoid the possibility of incurring a fine for any infraction. 


As you look these restrictions over, you’ll find they leave the greatest latitude for use in health, public safely and other high-priority needs. Where do the reductions come from?

  • Watering with sprinklers-for either landscaping or vegetable gardens-is restricted to the hours of 7 p.m. to 8 a.m. twice every seven days (Mandatory)
  • Outdoor water restrictions in effect: 
    • Customers with even numbered addresses may water on Sundays and Thursdays between the hours of 7 p.m. until 8 a.m. of the following day. 
    • Customers with odd number addresses may water on Saturdays and Wednesdays between the hours of 7 p.m. until 8 a.m. of the following day. 
    • Hose attachments are exempt if handheld, but sprinkler and other dispersal heads that are hose attachments left to run unattended are restricted to the same schedule as in-ground automatic systems.
  • New pools, hot tubs and similar amenities may not be filled or topped up.
  • Aesthetic uses such as in fountains and other purely ornamental functions may only be done with reused water.
  • The washing of impervious surface that causes water runoff is prohibited, except for immediate human health, safety and welfare.
  • Non-commercial washing of vehicles, trailers, boats and the like is permitted twice every seven days and is restricted to the hours of 7 p.m. to 8 a.m. on designated days (Mandatory).
  • Vehicle water restrictions in effect: 
    • Even number addresses may wash on Tuesday from 7 p.m. until Wednesday at 8 a.m. 
    • Odd number addresses may wash on Wednesday from 7 p.m. until Thursday at 8 a.m.
  • Restaurants may only serve water when specifically requested by a patron.
  • Sewer line and fire hydrant flushing is prohibited, except for emergencies.

Complaint Actions

The City has provided a number of ways that you may remain in lawful compliance while still managing to keep your favorite shrubs alive until rain does return, or enjoying other personal preferences:

  • You may water with hand-held hoses, buckets or drip systems.
  • You may irrigate at any time if reused water is employed.
  • You may fill and top up existing pools, hot tubs and similar amenities.

Sustainable Water Usage

There are more details you can look over in the longer document, but if you want the short version, here it is: Water resources across the state are beginning to reach stressed levels even in our large cities. It's a good time to recall that water is a precious resource that we've had in abundance in the past but now must rethink old patterns of use if we want sustainable water resources into the future. The Stage II conservation measures just implemented are a way for Pasadena residents and businesses to easily contribute to slowing unnecessary use until steady rainfall begins to recharge our water sources across the state.

Now that you know the challenges we face, take a few moments to look around your home or workplace and see if there examples of water waste you can correct. Most likely, you'll see there's a lot of room to improve water use efficiency while still enjoying the many benefits water brings into our lives.
