Find your watering rules
Choose your city and tell me whether your street address ends in an even or odd number. I'll show your assigned sprinkler days, the hours rule, and — the important one — how your foundation watering fits. Everything here reflects each city's permanent year-round schedule as of June 2026; always confirm the current drought stage with your city, since higher stages tighten the lawn schedule.
What can I water, and when?
Two quick choices. Your result updates instantly.
Non-residential properties (apartments, businesses, parks) typically water Tuesday & Friday. Don't see your city? The same Tarrant County framework applies region-wide — confirm your exact days on your city's water page.
All six cities at a glance
Every community in our service area is a Tarrant Regional Water District customer and runs the same permanent twice-a-week framework. Here's the whole picture in one table.
| City | Even addresses | Odd addresses | No watering | Foundation / drip |
|---|---|---|---|---|
| North Richland Hills | Wed & Sat | Thu & Sun | 10a–6p; Mondays (sprinklers) | Any day |
| Hurst | Wed & Sat | Thu & Sun | 10a–6p | Any day (~2 hrs) |
| Watauga | Wed & Sat | Thu & Sun | 10a–6p | Any day, up to 2 hrs |
| Haltom City | Wed & Sat | Thu & Sun | 10a–6p | Any day, up to 2 hrs |
| Keller | Wed & Sat | Thu & Sun | 10a–6p | Any day, up to 2 hrs |
| Southlake | Wed & Sat | Thu & Sun | 10a–6p | Any day |
Days shown are each city's permanent year-round assignment (the regional Tarrant County standard). Drought stages can change the lawn schedule — always confirm the current stage and your exact days on your city's official water page before relying on them.
Why drip and soaker watering gets a pass
It's not a loophole — it's the point of the rule. The twice-a-week schedule targets spray sprinklers, which apply water far faster than North Texas clay can absorb. On clay soil a spray head throws water roughly ten to twenty times faster than the ground takes it in, so a big share runs into the street. Limiting that to two days a week, outside the hottest hours, saves a lot of water.
Drip and soaker systems are the opposite. They release water slowly, low to the ground, right where it's needed, with almost nothing lost to runoff or evaporation. Because they're efficient, the ordinances treat them separately and allow them any day — and several explicitly call out foundations and high-value trees as exactly the reason for the allowance. North Richland Hills' ordinance puts it plainly: landscaping may be watered any day by drip or soaker hose to allow for the protection of structural foundations, trees, and other high-value landscape materials.
How drought stages change things
Tarrant Regional Water District sets the regional drought stage based on how full its reservoirs are. The cities adopt it. The permanent year-round rules above are the baseline; as reservoirs drop, stages tighten the sprinkler schedule — but the foundation and drip allowance is the consistent through-line designed to protect your home even in a drought.
Stages move with reservoir levels and can change during the summer. This page reflects the permanent baseline as of June 2026. Before you rely on a specific day, check your city's water page (linked in the tool above) for the current stage — and if you'd rather not track it, a properly programmed system keeps you both protected and compliant.
What this means for your foundation
Here's the practical upshot, and it's good news. The thing your foundation needs most — steady, consistent soil moisture, day in and day out — is exactly the thing the rules let you do without restriction. Your lawn is capped at two days a week; your foundation drip zone is not. That's why a dedicated foundation system isn't just effective on our clay, it's the watering you're always allowed to keep doing.
If you're weighing whether a foundation watering system is right for your home in the first place — what it does, what it doesn't, and whether you even need one — start with the full guide: Foundation drip irrigation: everything a North Texas homeowner needs to know. And if you want your system set up so it protects your slab and stays compliant with your city's current stage, that's part of what I confirm on every install.
