If you’ve lived in Austin for a while, you already know how different Texas landscapes can be from one region to the next. Up here in Central Texas, we’re used to dealing with hard water, seasonal algae blooms on Lake Travis, and the occasional boil-water notice. But if you also own property along the Gulf Coastor you’ve been keeping an eye on statewide water issues you may have heard more folks talking about saltwater intrusion.
Saltwater intrusion sounds dramatic, almost like something you’d see in a disaster movie, but it’s simply what happens when salty ocean water pushes into freshwater sources. It’s been an ongoing concern in several Texas coastal communities, especially those relying on shallow aquifers or wells near estuaries. And here’s the part that hits home for Austinites: water challenges across the state affect us more than most realize.
So today, I want to walk you through what saltwater intrusion means for coastal homes, plus what homeowners in Austin can do to protect their own water, whether it’s your primary residence here in Central Texas or a second home on the coast.
Saltwater Intrusion 101And Why Texans Should Pay Attention
Along the Gulf Coast from areas around Galveston Bay to parts of Brazoria and Matagorda Counties, freshwater aquifers sit close to the coastline. When drought, over-pumping, or rising sea levels reduce the amount of freshwater keeping saltwater at bay, that saltwater begins creeping inland.
For coastal homeowners, this can show up as:
- Water that tastes noticeably salty
- Damage to plumbing fixtures
- Corrosion on appliances and water heaters
- Mineral and salt buildup around faucets
- Dry, irritated skin and brittle hair
If you’ve ever spent time in Katy, Bellaire, or coastal neighborhoods south of Houston, you may have heard folks mention their water suddenly tasting “briny” or appliances wearing out early. That’s usually a sign of saltwater encroaching into local groundwater sources.
Now, Austin isn’t dealing with saltwater intrusionour water issues are completely different. But many Austin homeowners also have coastal properties. And even if you don’t, it’s helpful to understand how statewide water systems work, especially as Texas continues to grow.
What’s Actually in Austin Water? (And Why It Matters)
Here in Austin, our water comes mainly from the Colorado River and area reservoirs. While we’re safe from ocean salt, we’re certainly not strangers to our own set of water challenges. The most common issues I see in Austin homes include:
1. Hard Water Minerals
Austin sits on limestone-rich geology, so our water is loaded with calcium and magnesium.
Hard water causes:
- Chalky white buildup on sinks, fixtures, and shower doors
- Stiff laundry
- Dry skin and hair
- Shorter lifespan for water heaters, dishwashers, and coffee makers
If you’ve scrubbed cloudy spots off your dishes more times than you’d like to admit, you’re definitely feeling the effects of Austin’s hard water.
2. Chlorine and Treatment Byproducts
Austin Water disinfects municipal supply with chlorine. It keeps water safe, but many homeowners dislike the taste and smell.
3. Sediment
Seasonal weather eventsespecially heavy rain after long dry spellscan stir up sediment and organic material in our water sources. This can cause cloudy water or earthy taste.
4. PFAS and Emerging Contaminants
While Austin’s tap water is regularly monitored, PFAS (“forever chemicals”) are a growing concern nationwide. Many residents look for extra filtration simply for peace of mind.
Even though these aren’t coastal, they impact our homes in real, everyday waysplumbing, appliances, and personal comfort.
Recognizing Water Problems in Your Home
Whether it’s a beachfront house in Galveston or a condo in South Austin, water quality issues usually leave clues. Here are signs to watch for:
Signs of Saltwater Intrusion (Coastal Homes)
- Tap water tastes salty or metallic
- Corrosion on fixtures
- Appliances wearing out faster than expected
- Rust or mineral buildup around plumbing
- Dry, irritated skin after showers
Signs of Hard Water or Local Austin Issues
- White, chalky deposits around faucets
- Soap not lathering well
- Clothes feeling stiff after washing
- Smelly or odd-tasting tap water
- Cloudy ice cubes
- Coffee makers and kettles developing flaky buildup
A simple at-home test (taste, smell, residue on fixtures) can tell you a lot, but for a clear picture, a professional water test is the way to go. That’s where local companies like Aquapure make the process pretty painlessthey handle testing, installation, and long-term support with certified technicians.
Protecting Your Coastal Home from Saltwater Intrusion
If you’re one of the many Austinites who own or plan to own property near the Gulf Coast, here’s what you can do to safeguard your home’s water supply:
1. Install a Whole-Home Water Filtration System
A high-quality filtration setup can remove sediment, minerals, chlorine, and salts depending on the configuration. For coastal homes facing saltwater creep, reverse osmosis components are often recommended.
If you want to explore options, Aquapure offers customized solutions here:

2. Use a Water Softener to Protect Plumbing
Softening isn’t just for Austin’s hard waterit also helps reduce scale and mineral buildup in coastal homes.
Aquapure installs systems with free technician support and easy financing:

3. Monitor Your Water Regularly
Salt levels can change quickly with rainfall, drought, or well usage. Regular tests help you catch changes early before serious damage happens.
4. Protect Appliances
Dishwashers, water heaters, and washing machines are especially vulnerable to salt-related corrosion. Filtration and softening significantly extend their lifespan.
5. Consider a Point-of-Use Reverse Osmosis System
For drinking water, RO units are highly effective in coastal settings and can be paired with whole-home systems for full protection.
How Austin Homeowners Can Improve Their Water at Home
Even though we’re far from the coast, Austin water still benefits from some care. Here’s what improves water quality for most homes:
1. Water Softening
This is practically a must in Austin. It prevents scale, protects appliances, and helps bathrooms and kitchens stay cleaner with less scrubbing. Many homeowners notice softer skin and easier-to-manage hair almost immediately.
2. Whole-Home Filtration
This tackles chlorine, sediment, discoloration, and odd tastes or odors. It’s especially helpful during those occasional high-sediment periods after storms.
3. Under-Sink Reverse Osmosis for Drinking Water
If you’re worried about PFAS or want bottled-water taste straight from your tap, RO is a great solution.
4. Routine Testing
A quick annual test helps make sure your system stays dialed in, especially if you have a mix of softening and filtration.
Aquapure, being Texas-owned and family-operated for over a decade, specializes in tailoring these setups to your propertywhether it’s your main home in Austin or your beach house on the Gulf.

A Neighborly Tip: Home Water Systems Aren’t One-Size-Fits-All
Austin’s hard water requires a very different setup than a home in Surfside Beach dealing with saltwater creep. That’s why customized systems make such a difference. A technician can test your water and design a system around exactly what’s coming out of your tap.
Local FAQ: Austin Homeowners Ask All the Time
