New Port Richey Watering Days: When Can You Water Your Lawn?

If you live in New Port Richey, you can water your lawn one or two days a week, on days assigned by your address — and never between 10 a.m. and 4 p.m. Those rules come from the Southwest Florida Water Management District (SWFWMD), which covers all of Pasco County.

Here’s the problem I run into constantly: most sprinkler timers in New Port Richey are still running the schedule the builder set when the house was new. That schedule usually ignores current restrictions — which means you might be watering on the wrong days, wasting water, and risking a code notice without knowing it.

How your watering days are assigned

SWFWMD and Pasco County set watering days by your house address, typically split odd and even, one or two days a week depending on the time of year. The schedule tightens during dry season and can shift, so the honest answer is: look up your specific address on the current SWFWMD schedule rather than trust a number you heard once.

Two rules hold no matter what your days are:

• No watering 10 a.m.–4 p.m. — that’s peak evaporation, so most of it never reaches the roots.
• Early morning is best — watering before the sun is high gives the grass time to absorb it and dry before nightfall, which also helps prevent fungus.

Why your timer is probably wrong

When I get an irrigation call, the first thing I do — before touching a single sprinkler head — is check your assigned watering days and reset the controller to match. I’d say the majority of systems I open are still on a factory or installer default that doesn’t line up with current rules.

A wrong schedule costs you two ways:

1. Compliance risk — watering on a non-assigned day can get you a notice.
2. Money — an overwatering schedule, or a zone running mid-day, quietly runs up your water bill for months.

You can see how I handle timer setup and repairs on the irrigation and sprinkler page.

Watering the right amount, not just the right day

Getting the days right is half of it. The other half is watering deeply but less often. St. Augustine and Bahia lawns in our sandy soil do better with a longer soak on your assigned days than a light daily sprinkle — deep watering pushes roots down, which makes the lawn tougher through the dry months.

A few signs you’re watering wrong:

• Fungus or soggy low spots — usually too much, too often, or watering at night.
• Dry patches that never green up — often a coverage gap, a clogged head, or a broken zone, not a watering-frequency problem.
• A water bill that jumped for no clear reason — worth checking for a stuck valve or a hidden leak.

New sod and plants get a temporary pass

If you’ve just had new sod or plantings installed, you usually qualify for a temporary establishment-watering exemption — more frequent watering for a set window while roots take hold, then back to normal restrictions. When I install sod or new beds, I tell you the exact establishment schedule before I leave so you don’t lose the lawn or break the rules.

The bottom line

Water one or two days a week on your assigned days, never midday, and deep rather than daily. Then go check what your sprinkler timer is actually set to — it’s very likely wrong.

If you’d rather have someone set the timer correctly and fix whatever’s broken in the same visit, request a quote and I’ll check your coverage, your schedule, and your water-wasting zones all at once.
