Best Water Softener for Austin, TX — 15 Things to Know BEFORE You Buy!

Written by Craig "The Water Guy" Phillips

1. Austin's Extreme Water Hardness Crisis

Austin homeowners are unknowingly destroying their plumbing systems every single day. The city's water supply clocks in at a staggering 15.8 grains per gallon (GPG) — officially classified as "extremely hard" and ranking among the hardest municipal water supplies in Texas. To put this in perspective, every gallon flowing through your pipes contains enough dissolved limestone to coat a penny with visible mineral buildup.

Austin's water originates primarily from the Colorado River and Lake Travis, flowing through limestone-rich geological formations for millions of years. As water percolates through these calcium carbonate deposits, it becomes saturated with dissolved minerals. By the time it reaches your Zilker, South Austin, or Cedar Park home, each gallon carries 15.8 grains of dissolved rock — equivalent to about 270 milligrams of calcium and magnesium per liter.

At 15.8 GPG, Austin's water hardness functions like liquid sandpaper coursing through your home's infrastructure. Think of it as compound interest working against you: every shower, every load of laundry, every cup of coffee deposits microscopic mineral layers throughout your plumbing system. A typical Austin household circulates over 100,000 gallons annually, meaning nearly 40 pounds of dissolved limestone passes through your pipes each year.

The financial implications are immediate and measurable. Austin homeowners spend an estimated $1,800 to $2,400 annually on what water quality experts call the "hard water tax" — premature appliance replacement, excessive soap and detergent usage, increased energy bills from scale-clogged systems, and accelerated plumbing repairs. This doesn't account for the hidden costs: reduced home value from mineral-stained fixtures, higher dry cleaning bills from damaged clothing, and the daily frustration of battling white spotting on every surface water touches.

2. What 15.8 GPG Does to Your Austin Home

At 15.8 GPG, calcium carbonate doesn't just accumulate — it actively transforms your plumbing into a mineral museum. When Austin's extremely hard water is heated in your water heater, dissolved calcium and magnesium precipitate out of solution, forming crystalline deposits that coat heating elements like barnacles on a ship's hull. Within 12 to 18 months, a standard 40-gallon electric water heater can lose 35% to 45% of its heating efficiency due to scale buildup.

The scale formation process in Austin homes follows a predictable timeline. At 15.8 GPG, heating elements begin showing visible mineral coating within 90 days of installation. By month six, the bottom heating element in electric units develops a quarter-inch crusty layer that acts as thermal insulation, forcing the system to work exponentially harder. Gas water heaters suffer similar fate — scale accumulates on heat exchanger surfaces, creating hot spots that can crack the tank liner. Austin homeowners typically see their first water heater failure between years 4 and 6, compared to the manufacturer's projected 8 to 12-year lifespan in soft water regions.

Austin's older neighborhoods face compounded pipe damage from 15.8 GPG water hardness. In homes built before 1990, galvanized steel pipes are particularly vulnerable. The extreme mineral content creates concentric rings of calcite deposits that narrow pipe diameter by 20% to 30% over a decade. Tarrytown and Hyde Park residents frequently report diminished water pressure as scale accumulates in branch lines. Copper pipes, common in 1990s Austin construction, develop internal scaling that reduces flow rates and creates pressure differential issues throughout multi-story homes.

Appliance destruction accelerates dramatically at Austin's 15.8 GPG hardness level. Dishwashers typically survive 4 to 5 years before mineral buildup clogs spray arms and damages pump seals — half their expected lifespan. Washing machines face similar challenges as calcium deposits interfere with valve operation and clog internal screens. Tankless water heaters, popular in newer Austin developments, are especially vulnerable; manufacturers like Rinnai and Rheem often void warranties for installations without water softening in areas exceeding 7 GPG.

The soap and detergent waste at 15.8 GPG becomes a monthly budget line item. Calcium and magnesium ions chemically react with soap molecules to form insoluble precipitates — the gray scum that coats your shower walls. Austin households typically use 3 to 4 times more laundry detergent, dish soap, and shampoo than families in soft water cities. A typical Austin family of four spends an additional $400 to $600 annually on cleaning products that would be unnecessary with properly softened water.

Austin's extreme hardness creates measurable impacts on skin and hair health. At 15.8 GPG, calcium ions strip natural moisture from skin, leaving a mineral film that clogs pores and exacerbates conditions like eczema. Hair becomes coated with microscopic mineral deposits that make it feel coarse, look dull, and resist styling products. Many Austin residents report improved skin texture and hair manageability within days of installing a proper water softening system.

The annual "hard water tax" for Austin homeowners ranges from $2,200 to $3,100 per household. This includes accelerated appliance depreciation ($800-1,200), increased energy costs from scale buildup ($300-500), excessive soap and detergent purchases ($400-600), and premature plumbing repairs ($700-800). Over a 10-year period, Austin's 15.8 GPG water hardness costs the average homeowner between $22,000 and $31,000 in preventable expenses.

3. Austin's Specific Contaminant Profile Beyond Hardness

Austin's water profile presents a layered challenge: beyond the 15.8 GPG hardness baseline, residents are also contending with chloramine, fluoride, and sediment — each of which interacts with water hardness in its own way.

Chloramine in Austin's Water Supply

Austin Water switches from chlorine to chloramine disinfection during summer months when algae blooms in Lake Travis require more stable antimicrobial treatment. Chloramine is a compound of chlorine and ammonia that provides longer-lasting disinfection as water travels through Austin's extensive distribution system to outlying areas like Pflugerville and Round Rock. Unlike chlorine, which dissipates quickly, chloramine maintains its chemical structure throughout the pipe network.

At 15.8 GPG hardness, chloramine interacts with mineral scale deposits to create persistent taste and odor issues. The compound becomes trapped within calcium carbonate layers, releasing a characteristic "medicinal" or "band-aid" smell when hot water dissolves scale particles. Austin residents frequently notice this odor intensifying during summer months when chloramine concentrations are highest.

Chloramine presents unique removal challenges that standard carbon filtration cannot address. While regular activated carbon removes chlorine effectively, chloramine requires catalytic carbon media for proper reduction. The EPA secondary standard for chloramine is 4.0 mg/L, and Austin typically maintains levels between 1.5 and 3.0 mg/L — well within safety guidelines but noticeable to sensitive individuals.

The SoftPro Elite HE water softener does not remove chloramine. Austin homeowners dealing with both extreme hardness and chloramine taste/odor concerns should consider a catalytic carbon whole-house filter upstream of the softener system.

Fluoride Addition in Austin

Austin Water adds fluoride to the municipal supply at the CDC-recommended level of 0.7 mg/L for dental health benefits. This intentional addition occurs at the treatment plant and remains stable throughout distribution. Fluoride does not interact chemically with Austin's 15.8 GPG hardness, but its presence concerns some residents seeking comprehensive water treatment.

Water softeners do not remove fluoride from Austin's water supply. The ion exchange resin in softening systems targets calcium and magnesium ions specifically, leaving fluoride molecules unchanged. Austin residents who prefer fluoride-free drinking water require a reverse osmosis system at kitchen taps, which can operate effectively downstream of a whole-house softener.

Austin maintains fluoride levels well below the EPA's maximum contaminant level of 4.0 mg/L. Regular testing confirms concentrations remain stable around the target 0.7 mg/L throughout the distribution system.

Sediment and Turbidity Issues

Austin's aging water infrastructure occasionally releases sediment particles into residential lines, particularly during main breaks or system maintenance. The city's rapid growth has stressed distribution systems installed in the 1970s and 1980s, leading to periodic turbidity events that leave tap water cloudy or discolored.

Sediment becomes especially problematic when combined with Austin's 15.8 GPG hardness. Suspended particles provide nucleation sites for mineral crystallization, accelerating scale formation inside water heaters and appliances. Additionally, sediment can clog and damage water softener resin over time, reducing system efficiency and requiring more frequent maintenance.

Austin residents should expect occasional "boil water" notices following infrastructure repairs. These events, while temporary, highlight the importance of sediment pre-filtration for any whole-house water treatment system. The SoftPro Elite HE includes integrated sediment pre-filtration specifically designed to protect the softening resin from particulate damage.

4. Why Most Austin Homeowners Pick the Wrong Softener

Austin's extreme 15.8 GPG hardness exposes every shortcut and mistake in water softener selection. After consulting with hundreds of frustrated homeowners across Travis County, four critical errors emerge repeatedly — mistakes that cost Austin families thousands in wasted money and continued hard water damage.

Mistake 1: Buying on Price Alone

A $400 box store softener marketed as "adequate for most homes" will fail spectacularly in Austin's 15.8 GPG environment. These undersized units typically contain 24,000 to 32,000 grains of resin — sufficient for moderately hard water cities but completely overwhelmed by Austin's mineral load. At 15.8 GPG, a family of four exhausts a 32,000-grain system in 2 to 3 days, forcing near-constant regeneration that wastes salt and water while still allowing hard water breakthrough during peak usage periods.

The resin quality in budget softeners deteriorates rapidly under Austin's extreme conditions. Cheap plastic beads crack and fragment when subjected to high mineral concentrations, creating channels that allow untreated hard water to bypass the softening process. Within 18 months, many Austin homeowners discover their "bargain" softener is delivering water testing 8 to 12 GPG — still extremely hard and still damaging their plumbing.

Mistake 2: Confusing Softeners with Filters

Austin residents often expect a single water softener to solve every water quality issue in their home. Softeners use ion exchange resin to remove calcium and magnesium minerals — period. They do not reliably remove chloramine, fluoride, or sediment from Austin's water supply. Homeowners who install a softener expecting chlorine-free, fluoride-free, and perfectly clear water will be disappointed and may incorrectly assume their system is malfunctioning.

Austin's multiple contaminant profile requires a systems approach. The SoftPro Elite HE addresses mineral hardness completely, but residents concerned about chloramine taste or fluoride ingestion need companion filtration systems designed for those specific contaminants.

Mistake 3: Ignoring Grain Capacity Math

Austin's 15.8 GPG demands precise grain capacity calculation to avoid system overload. The formula is straightforward: household members × 75 gallons per day × 15.8 GPG = daily grain demand. A family of four needs 4,740 grains of capacity daily — meaning a 32,000-grain system should regenerate every 6 to 7 days for optimal efficiency. Many Austin homeowners purchase undersized systems that regenerate every 2 to 3 days, wasting salt and reducing resin lifespan.

Peak usage days in Austin can double normal grain demand. Pool parties, houseguests, and landscape irrigation can push a household from 300 gallons daily to 600 gallons. Without adequate grain capacity reserve, hard water breakthrough occurs during these high-demand periods, allowing scale formation even in homes with softening systems.

Mistake 4: Overlooking Salt Efficiency

At Austin's 15.8 GPG, an inefficient softener becomes a salt-consuming monster. Older single-tank systems or poorly designed units can use 15 to 20 pounds of salt per regeneration cycle. With regeneration occurring weekly or more frequently, Austin homeowners may find themselves hauling 80 to 100 bags of salt annually — a back-breaking and expensive routine that compounds over years.

High-efficiency systems like the SoftPro Elite HE use demand-initiated regeneration and optimized brine cycles to minimize salt consumption. Over 10 years of operation in Austin's extreme conditions, the salt savings between an efficient and inefficient system can exceed $2,000 while reducing the physical burden of constant salt bag purchases.

5. What Austin Homeowners Should Check Before Buying

Test your current water hardness using a reliable TDS meter or professional lab analysis. While Austin Water reports system-wide averages of 15.8 GPG, individual neighborhoods can vary by 1 to 3 grains depending on distribution routing and seasonal factors. Homes in Northwest Austin near Lake Travis may test slightly lower, while East Austin properties might show higher concentrations due to pipe scaling in older infrastructure.

Verify your home's daily water usage by reading your meter for one week. Austin's tiered water pricing structure means you already have detailed consumption data on your monthly bill. Look for the "gallons used" figure and divide by days in the billing period. Most Austin households use 200 to 400 gallons daily, but large families or homes with pools and irrigation can exceed 600 gallons during summer months.

Inspect your current water heater for scale damage before softener installation. Remove the access panel and examine heating elements or heat exchanger surfaces for white, crusty buildup. Heavy scaling indicates your system has already suffered efficiency loss, and you should plan for earlier replacement even after installing a softener. Document the condition with photos for future reference.

Check your home's main water line pressure using a simple gauge from any Austin hardware store. Austin Water maintains system pressure between 50 and 80 PSI in most areas, but individual homes can vary due to elevation, distance from mains, and internal plumbing restrictions. Water softeners require minimum 20 PSI to operate effectively, and optimal performance occurs above 40 PSI.

6. Homeowner Checklist for Austin Water Treatment

Locate your main water shutoff valve and measure the pipe diameter. Most Austin homes built after 1980 have 3/4-inch or 1-inch copper supply lines, which accommodate standard softener connections. Older homes may have 1/2-inch lines that restrict flow rates and require professional evaluation before softener installation.

Identify a suitable installation location with these requirements: level concrete or sturdy flooring, electrical outlet within 6 feet, drain access within 20 feet, and adequate clearance for salt loading. Austin's clay soil can cause foundation shifting, so avoid areas with visible settling or cracking.

Research Austin's plumbing permit requirements for your specific area. While softener installation typically doesn't require permits, some Travis County jurisdictions have specific backflow prevention requirements for systems that discharge regeneration brine. Contact your local authority having jurisdiction before installation.

Plan for salt delivery and storage in Austin's climate. Summer temperatures exceeding 100°F can cause salt bridging in humid conditions. Choose a cool, dry storage location away from direct sunlight, and consider having salt delivered during cooler months to avoid heat-related storage problems.

7. The SoftPro Elite HE: Built for Austin's Water

After evaluating Austin's water hardness of 15.8 GPG and the presence of chloramine, fluoride, and sediment in the local supply, one system consistently rises to the top for Austin homeowners: the SoftPro Elite HE Water Softener.

True salt-based ion exchange provides the only reliable solution for Austin's extreme 15.8 GPG hardness. Salt-free systems marketed as "conditioners" or "descalers" do not actually remove calcium and magnesium minerals — they only attempt to alter crystal structure through electromagnetic fields or template-assisted crystallization. At Austin's mineral concentration, these alternative methods cannot prevent scale formation. The SoftPro Elite HE uses proven cation exchange resin that physically replaces every calcium and magnesium ion with sodium, delivering genuinely soft water that tests below 1 GPG.

Demand-initiated regeneration becomes operationally essential at Austin's 15.8 GPG consumption rate. Traditional timer-based systems regenerate on fixed schedules regardless of actual water usage, leading to either wasteful over-regeneration or dangerous under-regeneration that allows hard water breakthrough. The SoftPro's DIR technology monitors actual grain depletion and initiates regeneration only when resin approaches exhaustion. For Austin households where resin exhausts rapidly due to extreme hardness, this prevents the hard water breakthrough that would otherwise occur during high-usage periods.

NSF/ANSI Standard 44 certification verifies that the SoftPro Elite HE meets rigorous performance and materials safety standards. For Austin residents already managing chloramine and fluoride in their water supply, knowing the softening process itself doesn't introduce additional contaminants provides critical peace of mind. The certification testing includes verification of sodium contribution, structural integrity under pressure cycling, and long-term performance stability.

Multiple grain capacity options (32K, 48K, 64K, 80K) allow precise sizing for Austin's demanding conditions. A typical Austin family of four consuming 300 gallons daily needs 4,740 grains of capacity per day (4 people × 75 gallons × 15.8 GPG). Adding a 20% buffer for high-usage days brings the requirement to 5,688 grains daily, or approximately 39,816 grains weekly. This calculation points to the 48,000-grain SoftPro Elite HE model for optimal 7-day regeneration cycles.

The 10-year warranty provides Austin homeowners with protection during the years of highest mineral stress. At 15.8 GPG, softener resin processes more minerals monthly than systems in soft-water cities handle annually. This accelerated duty cycle can reveal manufacturing defects or premature component wear that might not appear in gentler operating environments. SoftPro's extended warranty coverage acknowledges the demanding service conditions in cities like Austin.

Integrated sediment pre-filtration protects the softening resin from Austin's periodic turbidity events. When main breaks or system maintenance introduce sediment into Austin's distribution network, particulate matter can clog resin beds and create channeling that allows hard water bypass. The SoftPro Elite HE's self-cleaning pre-filter captures sediment before it reaches the resin tank, maintaining consistent softening performance and extending resin life in Austin's challenging environment.

For Austin households dealing with 15.8 GPG of water hardness and the compounding presence of chloramine, fluoride, and sediment, the SoftPro Elite HE is not a comfort upgrade — it is infrastructure protection for your home.

8. How to Size Your Softener for Austin

Austin's extreme 15.8 GPG hardness demands precise capacity calculations to prevent system overload and hard water breakthrough. Follow this step-by-step sizing process to ensure your investment delivers consistent soft water protection:

Step 1: Count household members — Include anyone living in the home full-time, including children and elderly family members who may have different usage patterns.

Step 2: Multiply by 75 gallons per person per day — This figure accounts for drinking, cooking, bathing, laundry, and general household use based on Austin Water's residential consumption data.

Step 3: Multiply household gallons × 15.8 GPG = daily grain demand — This calculation determines how much hardness mineral your softener must remove daily.

Step 4: Multiply daily grain demand × 7 = weekly grain demand — Weekly calculations provide better capacity planning than daily figures for residential systems.

Step 5: Add 20% buffer for high-usage days — Austin summers, pool parties, and houseguests can double normal water consumption unexpectedly.

Step 6: Match to SoftPro Elite HE grain tier — Select the capacity that accommodates your buffered weekly demand without excessive over-sizing.

Here's the calculation worked out for a typical 4-person Austin household:
4 people × 75 gallons = 300 gallons daily
300 gallons × 15.8 GPG = 4,740 grains daily
4,740 grains × 7 days = 33,180 grains weekly
33,180 grains + 20% buffer = 39,816 grains needed
Recommended: SoftPro Elite HE 48,000-grain model

This sizing delivers optimal 5 to 7-day regeneration cycles that maximize salt efficiency while ensuring consistent soft water delivery. Regenerating more frequently than every 5 days wastes salt and water; regenerating less frequently than every 7 days risks resin exhaustion and hard water breakthrough during peak demand periods.

9. Installation in Austin: What to Know

Austin and Travis County generally do not require licensed plumber installation for residential water softeners, but complex situations may warrant professional help. Most homeowners with basic DIY skills can complete installation using standard plumbing fittings and the comprehensive instructions included with the SoftPro Elite HE.

Proper placement follows this sequence: after your main shutoff valve and pressure regulator, before your water heater and any branch lines. This ensures all water entering your home receives softening treatment while maintaining access to bypass the system for maintenance. Austin homes typically have main lines entering through the garage, utility room, or basement area where space permits proper installation.

Plan for regeneration discharge requirements in Austin's clay soil environment. The SoftPro Elite HE discharges approximately 50 gallons of brine solution during each regeneration cycle. This can drain to a utility sink, standpipe, or approved floor drain, but should not discharge directly onto Austin's expansive clay soil, which can shift and crack with repeated wetting and drying cycles.

Austin's municipal water pressure typically ranges from 50 to 80 PSI throughout most residential areas. This pressure range is ideal for the SoftPro Elite HE, which operates optimally between 25 and 80 PSI. Homes in elevated areas like the Hills of Lakeway or high-rise condos downtown may experience lower pressure that requires evaluation before installation.

At Austin's 15.8 GPG consumption rate, use only evaporated salt pellets for optimal performance. The extreme mineral concentration demands the highest purity salt to minimize brine tank residue and prevent bridging in Austin's hot, humid summers. Solar salt crystals, while more economical, contain impurities that can accumulate faster in high-usage systems and create maintenance headaches.

Check salt levels monthly during Austin's peak summer months when regeneration frequency increases. High usage combined with 15.8 GPG hardness can push regeneration to every 4 to 6 days during June through September, requiring more frequent monitoring than systems in moderate climates.

10. Maintenance Schedule for Austin Homeowners

Austin's extreme 15.8 GPG hardness accelerates wear on all softener components, making consistent maintenance essential for long-term performance. This schedule is calibrated specifically for Austin's demanding operating conditions:

Monthly maintenance becomes critical during Austin summers: Check salt level and consumption patterns, as high usage and frequent regeneration can deplete salt supplies faster than expected. Inspect for salt bridges — a hard crust above the water line that prevents proper brine formation. Austin's temperature swings between air-conditioned interiors and 100°F+ outdoor conditions can promote bridging in humid conditions. Verify the bypass valve remains in service position, as vibration from Austin's frequent construction and heavy truck traffic can occasionally shift valve positions.

Every 3 months, perform more detailed system checks: Clean the brine tank to remove any sediment or salt residue that accumulates faster in high-usage systems. Test post-softener water hardness using test strips — properly functioning systems should deliver water below 1 GPG consistently. Inspect and clean the integrated sediment pre-filter, which captures particulate matter from Austin's aging distribution infrastructure.

Annual maintenance prevents costly repairs and ensures continued performance: Conduct thorough brine tank cleaning with complete salt removal and tank sanitization. Perform comprehensive resin bed performance evaluation — if post-softener hardness creeps above 1 GPG despite proper operation, resin may need cleaning or replacement. Austin's mineral load can exhaust resin faster than manufacturer estimates suggest. Audit regeneration cycles to confirm timing and salt dosing remain optimal for your household's actual consumption patterns.

Every 5 years, evaluate major component condition: Assess resin replacement needs based on actual performance testing rather than calendar age. At Austin's 15.8 GPG demand, resin may require replacement 20% to 30% sooner than systems operating in moderate hardness environments. Consider upgrading capacity if household size has increased or if usage patterns have changed significantly since initial installation.

Austin residents should establish baseline performance measurements before installation and retest 30 days later to confirm the system meets expectations. Document these results for future maintenance reference and warranty purposes.

11. Is Austin's water at 15.8 GPG dangerous to drink?

Austin's 15.8 GPG water hardness is not dangerous to drink and actually provides beneficial calcium and magnesium minerals. The EPA does not regulate water hardness as a health concern, and many nutritionists consider moderate mineral intake from water to be advantageous. However, the extreme hardness level creates significant infrastructure and quality-of-life problems that justify treatment for non-health reasons.

12. Will a water softener remove chloramine from Austin's water?

No, the SoftPro Elite HE water softener will not remove chloramine from Austin's municipal supply. Softeners target calcium and magnesium ions specifically through ion exchange resin. Chloramine requires catalytic carbon filtration for effective removal. Austin residents concerned about chloramine taste or odor should install a whole-house catalytic carbon filter upstream of their softener system.

13. How much salt will I use per month in Austin at 15.8 GPG?

A typical Austin family of four will use approximately 80 to 120 pounds of salt monthly with the SoftPro Elite HE system. This estimate assumes 300 gallons daily consumption, weekly regeneration cycles, and the high-efficiency salt dosing that characterizes properly sized systems. During peak summer usage, monthly salt consumption can increase to 140 to 160 pounds as regeneration frequency increases with higher water demand.

14. Does Austin require a permit to install a water softener?

Austin and Travis County generally do not require permits for residential water softener installation. However, some municipal utility districts in the greater Austin area have specific backflow prevention requirements for systems that discharge brine solutions. Contact Austin Water or your local MUD office to verify requirements for your specific address before installation.

15. Why does soft water feel slippery in the shower?

Soft water feels slippery because it allows your skin's natural oils to remain on the surface instead of being stripped away by mineral deposits. Austin residents accustomed to 15.8 GPG water often mistake this natural, healthy skin condition for "soapy" or "slippery" water. The sensation indicates the softener is working properly — your skin is experiencing its natural moisture balance for the first time in years.

Final Verdict for Austin

Austin's hardness of 15.8 GPG demands commercial-grade treatment in a residential package. This isn't moderate hardness that homeowners can ignore or manage with alternative methods — this is extreme mineral concentration that actively destroys plumbing infrastructure, doubles energy costs, and creates thousands of dollars in annual "hard water tax" expenses.

Chloramine, fluoride, and periodic sediment compound the hardness problem by creating taste issues, requiring companion filtration, and accelerating resin fouling. Any water treatment solution for Austin must acknowledge these multiple challenges and provide either integrated or compatible treatment approaches.

The SoftPro Elite HE rises above other options because of its demand-initiated regeneration that prevents hard water breakthrough, its NSF-certified resin that handles extreme mineral loads, and its integrated sediment pre-filtration that protects against Austin's infrastructure challenges. The 10-year warranty provides protection during the demanding service conditions that characterize Austin's water environment.

Check current SoftPro Elite HE pricing and available grain capacities for Austin households. The 48,000-grain model suits most families, while larger households or those with pools should consider 64,000 or 80,000-grain configurations. Professional installation is available, but many Austin homeowners successfully complete DIY installation using the comprehensive instructions provided.

Twenty years from now, when Lake Travis water levels fluctuate and Austin's population doubles again, your SoftPro Elite HE will still be protecting your home's plumbing just like the limestone bluffs have been protecting the Colorado River for millions of years.
