Mandatory Water Conservation measures in effect for the City of Houston.  Basically it states to stop watering your grass and quit wasting water.

Ways to conserve water:

• Keep showers under five minutes
• Turn water off while brushing your teeth
• Wash only full loads of dishes or clothes
• Replace older model showerheads and faucet aerators with new low-flow models and install low water use toilets
• Inspect toilets for silent leaks by putting food coloring in the toilet tank. If colored water leaks into the toilet bowl before flushing, water is being lost due to a worn flapper
• Refrain from washing any vehicle or motorbike unless the dirt poses a driving hazard
• Refrain from washing down any sidewalk, walkway, driveway, parking lot or any other hard-surfaced area
• Refrain from filling, refilling or adding water to any indoor or outdoor swimming pool, spa or whirlpool.
