Where Should I Drain My Pool Water To?
For most Tucson homeowners, discharging pool water through a private-property sewer cleanout is the preferred option. You can also use the drain water on your own landscaping, as long as it is absorbed without causing damage or leaving the property. However, off-site drainage, including storm drains, may not be the best way to drain pool water for everyone.
How you drain a swimming pool matters just as much as where. There are specific rules and regulations regarding sanitary sewer discharge, landscape irrigation, off-site surface drainage, and filter backwash treatment in Tucson.
So, where should I drain my pool water to? Keep reading this practical guide to find out.
Can I Drain My Swimming Pool Water into the Sewer in Tucson?
You can drain your pool water into the sanitary sewer system. In fact, it’s the preferred method. Here's how to do it right:
Locate the access cap of the private-property sewer cleanout before you start. It's typically a black cap set into the ground somewhere between the house and the property line.
Once you've found the cleanout, run a hose from the pool to that cap and connect it there. Tucson recommends discharging during lower-use hours, such as the afternoon or late at night, when the sewer system isn't already handling peak household flow.
Use a small-volume pump, and keep the discharge controlled so the water doesn't spill or overwhelm the line.
Pima County's system treats the water that comes through, and some of that treated water eventually gets reclaimed for irrigation. Draining this way means the water can be efficiently put back to use.
Can You Drain Your Pool Water onto Your Yard in Tucson?
Often, yes. The City says it's wise to use pool drainage water for landscape irrigation on your own property whenever possible.
Before you run a garden hose out to the yard, though, think through the following three things:
Can the soil outside soak up the volume you're sending its way?
Will the water stay entirely on your property, or is it likely to cross a fence line?
Could it damage plants or cause erosion along the way?
Desert ground doesn't always absorb water quickly, and a large volume released at once can lead to pooling, flooding, or erosion.
There's also salt to consider. Tucson provides guidance on salt-tolerant versus salt-sensitive plants, and that’s an important point to note. It’s best to spread the discharge across a suitable area instead of saturating one small section, and move the hose as you go.
What If You Don't Have a Sewer Cleanout?
If you don’t have a sewer cleanout, you can consider off-site surface drainage. But don’t open a public manhole, connect to public sewer infrastructure, or run a hose wherever the ground happens to slope downhill. That kind of neglect can lead to erosion, flooding, or a system failure you didn't see coming.
Off-site surface drainage is possible, but only under specific conditions. If you're unsure which route applies to your situation, consult a pool professional for advice before you drain. They can also explain what month is best to set up a pool.
When Can You Drain a Pool to a Street, Storm Drain, or Wash?
While this shouldn’t be the first-choice method for draining pool water, it’s available for homeowners who don’t have much of a choice. Off-site surface drainage to a street, storm drain, or wash is allowed only when every condition on the list below is met:
You don’t have access to a private sewer cleanout.
The pool must remain untreated for at least 72 hours after the last chlorine addition.
The water should not only be dechlorinated, but its pH should fall between 7 and 8.
The water needs to be clean, not cloudy or discharged while discolored, and free of algae or other pollutants.
When conditions line up, Tucson's guidance contemplates directing the flow through a temporary flexible hose toward an appropriate drainage route. The flow should be controlled enough so that it doesn't cause erosion or carry sediment. It should never run onto a neighbor's property, cross a sidewalk, or block street access, and it should stay clear of creeks and anywhere wildlife might be affected.
What Changes If You Have a Saltwater Pool?
Saltwater pool discharge is handled much differently from draining a freshwater pool. Since it contains higher total dissolved solids (TDS), it can affect your landscape. High TDS levels can be hard on salt-sensitive plants exposed to Tucson's intense sun, and unlike a pool liner, desert soil doesn’t hold up well when exposed to it.
Pool Water vs. Filter Backwash: Don't Treat Them the Same
Draining a pool and backwashing a filter aren't the same thing. Pool drainage is a large volume released all at once when you're partially or fully emptying the pool. On the other hand, backwashing a filter involves washing the filter, which can have elevated chlorine levels, pathogens, and other contaminants despite the smaller volume.
Backwash water should generally soak into your own property or go to the sanitary sewer, the same as other pollutant-bearing pool water. Move the backwash hose regularly so one spot isn't repeatedly saturated. Left to sit in one place, water like this can pool and attract mosquitoes. Also, make sure it doesn't flow on the street or onto your neighbor's property.
What About an Acid-Washed Pool?
Acid-washed pool water should not be discharged off-site. The acid-wash process leaves the water more aggressive than ordinary pool water. Plus, it’s mixed with other chemicals that make it genuinely harmful to whatever it touches on its way out.
Don't assume the standard 72-hour wait fixes this. That waiting period applies to treated water clearing chlorine. If your pool has been acid washed, talk to a professional about how to dispose of it properly.
Before You Turn On the Pump: Tucson Pool-Draining Checklist
Run through the following checklist before you drain your pool:
Identify your disposal destination first.
Locate the private sewer cleanout if you're using the main drain route to the sewer.
Test pH.
Check chlorine and disinfection status.
Confirm the water is clean, clear, and free of algae or contaminants.
Determine whether the pool was acid washed.
Verify landscaping water will stay on your property.
Inspect the discharge route for potential erosion and make sure the water won’t cross sidewalks, streets, or neighboring property.
Keep the flow controlled from start to finish, rather than walking away.
