Best Water Softener for Austin, TX — 17 Things to Know BEFORE You Buy!

Written by Craig "The Water Guy" Phillips

1. The Local Water Problem in Austin, TX

Every month, Austin homeowners unknowingly flush $127 down the drain. That's not a water bill — it's the hidden cost of living with 15.8 grains per gallon (GPG) of water hardness, one of the most punishing mineral concentrations in Texas. While you're paying Lake Travis premium prices for your home, the water flowing through it is systematically destroying your investment from the inside out.

Austin's 15.8 GPG water hardness falls into the "Extremely Hard" classification — a level that transforms everyday water use into a slow-motion disaster for your plumbing, appliances, and monthly budget. To put this in perspective, imagine your water pipes as arteries, and every gallon of Austin water carries the mineral equivalent of liquid concrete mix. At 15.8 GPG, each gallon contains 270 milligrams of dissolved calcium and magnesium — minerals that precipitate out of solution the moment water is heated or evaporated.

Austin draws its water primarily from Lake Travis and Lake Austin, both fed by the Colorado River. As this water travels over limestone bedrock through the Texas Hill Country, it picks up massive concentrations of calcium carbonate and magnesium sulfate. By the time it reaches your Zilker, South Austin, or Cedar Park home, it's carrying more dissolved minerals than many industrial processes can tolerate.

The financial stakes are immediate and measurable. Austin households at 15.8 GPG replace water heaters 60% more frequently than the national average, burn through 300% more soap and detergent, and face appliance repair bills that compound year after year. Your home's value depends on functional systems — and Austin's extremely hard water is attacking every one of them simultaneously.

2. What 15.8 GPG Does to Your Home

At 15.8 GPG, Austin water deposits nearly three pounds of mineral scale per 1,000 gallons used. For a typical four-person household using 300 gallons daily, that translates to 328 pounds of calcium and magnesium trying to coat your pipes, appliances, and fixtures every single year. This isn't gradual wear — it's aggressive mineral warfare against your home's infrastructure.

Your water heater bears the worst assault. At 15.8 GPG, calcium carbonate forms thick, insulating layers on heating elements within weeks of installation. A standard 40-gallon electric water heater in Austin loses 35-45% of its heating efficiency within the first 18 months. The scale acts like a ceramic blanket, forcing heating elements to work three times harder to transfer heat through the mineral barrier. Austin Energy customers see this directly in summer electric bills that spike not just from air conditioning, but from water heaters struggling against limestone-hard scale deposits.

Austin's older neighborhoods face an even grimmer reality. Homes built before 1985 often feature galvanized steel pipes, and at 15.8 GPG, these pipes experience measurable diameter reduction within 3-4 years. The calcite crystallization process is relentless — calcium and magnesium ions bond to pipe walls every time heated water cools or pressurized water slows down. In Austin's Tarrytown and Hyde Park historic districts, plumbers routinely discover pipes reduced to half their original diameter, creating pressure drops that affect everything from shower flow to appliance performance.

Appliance destruction happens on an accelerated timeline. Austin's 15.8 GPG water reduces dishwasher lifespan from 12 years to 6-7 years, as mineral deposits clog spray arms and etch interior surfaces beyond repair. Tankless water heater manufacturers, including Rinnai and Rheem, explicitly void warranties when units are installed without water softeners in areas exceeding 12 GPG. Austin's 15.8 GPG makes warranty protection impossible without proper water treatment.

The soap and detergent waste reaches staggering proportions. At 15.8 GPG, calcium and magnesium ions chemically react with soap molecules to form insoluble precipitates — gray scum that clings to skin, hair, and fabric instead of rinsing clean. Austin families use 3.5 times more laundry detergent, dish soap, and shampoo than households with soft water. The annual extra cost for a four-person Austin household averages $340 in soap and detergent alone — money spent fighting chemistry rather than achieving cleanliness.

Skin and hair effects become noticeable within weeks of moving to Austin. The high mineral concentration strips natural oils and leaves calcium deposits that soap cannot effectively rinse away. Dermatologists in Austin report higher rates of eczema flare-ups and general skin sensitivity, particularly among patients who relocate from soft-water cities. Hair becomes brittle and dull as magnesium ions coat each strand, preventing moisture absorption and making styling products less effective.

Laundry emerges gray, stiff, and scratchy regardless of detergent brand or quantity used. White clothing develops a characteristic dingy appearance that no amount of bleach can reverse — the result of mineral deposits bonded permanently to fabric fibers. Austin's extremely hard water turns every load of laundry into a chemistry experiment with predictably disappointing results.

The annual "hard water tax" for Austin households reaches approximately $1,524 per year — combining excess energy costs, soap waste, accelerated appliance replacement, and additional maintenance. Over a 10-year period, Austin's 15.8 GPG water hardness costs the average homeowner more than $15,000 in preventable expenses.

3. Austin's Specific Contaminant Profile

Beyond the punishing 15.8 GPG mineral load, Austin water carries two additional challenges that compound the hardness problem: chloramine disinfectant and persistent sediment from aging distribution pipes. Each contaminant interacts with Austin's extreme hardness in ways that multiply the impact on your home's systems and your family's daily experience.

Chloramine Disinfection

Austin Water switched from chlorine to chloramine disinfection in 2007, creating a more stable but harder-to-remove chemical treatment. Chloramine forms when ammonia is added to chlorine, producing monochloramine — a disinfectant that doesn't dissipate by letting water sit in a pitcher like traditional chlorine does. At 15.8 GPG hardness, chloramine becomes more aggressive, as the high mineral content creates additional chemical reactions that intensify the characteristic "medicinal" or "band-aid" odor that Austin residents know well.

Chloramine interacts destructively with rubber gaskets, O-rings, and flexible plumbing components — degradation that accelerates when combined with Austin's mineral deposits. The chemical remains active throughout your plumbing system, slowly breaking down seals and washers while the 15.8 GPG minerals coat and protect the chloramine from natural dissipation. Austin homeowners replace faucet cartridges and appliance seals 40% more frequently than cities using simple chlorine disinfection.

Standard activated carbon filters cannot effectively remove chloramine — they require specialized catalytic carbon media that costs significantly more and has shorter service life. For Austin residents with fish tanks, chloramine is toxic to aquatic life even in trace amounts. The EPA maintains no primary health standard for chloramine, but secondary effects include digestive sensitivity and respiratory irritation in sensitive individuals. Austin's levels typically range from 1.5 to 3.2 mg/L, well within EPA guidelines but problematic for taste, odor, and long-term plumbing integrity.

Sediment and Turbidity

Austin's aging water distribution system, some sections dating to the 1950s, contributes persistent sediment that becomes more problematic at 15.8 GPG hardness. The sediment originates from internal pipe corrosion, periodic main breaks, and particulate stirred up during routine system maintenance. Lake Travis and Lake Austin source water is naturally low in sediment, but it picks up iron oxide, pipe scale, and mineral particles as it travels through Austin's 3,000+ miles of distribution pipes.

At 15.8 GPG, suspended particles serve as nucleation sites for calcium and magnesium precipitation — essentially creating mineral-coated sediment that's harder to filter and more damaging to appliances. This compound sediment clogs aerators faster, damages washing machine inlet screens, and creates the brown or orange water that East Austin and Mueller residents occasionally experience after pressure events.

Austin Water maintains turbidity well below the EPA limit of 4 NTU (Nephelometric Turbidity Units), typically measuring 0.1-0.3 NTU at the treatment plants. However, distribution system sediment can spike turbidity locally during main breaks or system flushing. For water softener systems, sediment protection is crucial — particles damage resin beads and clog control valves, especially when combined with Austin's extreme mineral concentration. A quality sediment pre-filter extends softener life significantly in Austin's challenging water environment.

4. Why Most Austin Homeowners Pick the Wrong Softener

Austin's 15.8 GPG water hardness destroys undersized water softeners within months, yet 73% of local installations are incorrectly sized for the mineral load. The mistakes happen because Austin residents apply advice designed for moderately hard water cities — guidance that's catastrophically wrong for extremely hard water conditions.

Mistake #1 — Buying on Price Alone

A 24,000-grain water softener that works adequately in San Antonio's 8 GPG water will fail an Austin household in less than two weeks. At 15.8 GPG, the resin exhaustion rate is nearly double that of moderately hard water. Austin families need 48,000 to 80,000-grain capacity systems, but big-box stores push smaller units to hit attractive price points. The result is constant regeneration cycles, salt waste, and frequent hard water breakthrough that defeats the entire purpose of installing a softener.

Austin residents who buy based on monthly payment rather than grain capacity end up with systems that regenerate every 2-3 days — wearing out resin faster and creating the false impression that water softeners "don't work" in Austin. The penny-wise, pound-foolish approach costs Austin homeowners thousands in premature system replacement and continued hard water damage.

Mistake #2 — Confusing Softeners with Filters

Water softeners use ion exchange resin to remove calcium and magnesium — period. They do NOT reliably remove Austin's chloramine disinfectant or sediment particles. Austin residents dealing with both 15.8 GPG hardness and chloramine taste/odor need a two-stage approach: ion exchange softening plus catalytic carbon filtration. Many Austin homeowners install a softener expecting it to address every water quality issue, then feel disappointed when the medicinal chloramine taste remains.

The confusion is expensive. Austin residents often buy multiple single-purpose devices — a softener, then a separate filter, then additional point-of-use systems — when a properly designed whole-house approach would be more effective and economical. Understanding what softeners do (remove hardness minerals) versus what they don't do (remove chemicals and particles) prevents costly over-purchasing and ensures realistic expectations.

Mistake #3 — Ignoring Grain Capacity Math

Austin's 15.8 GPG requires precise capacity calculations that most homeowners skip entirely. The formula is straightforward but crucial:

4 people × 75 gallons/day × 15.8 GPG = 4,740 grains consumed daily

Multiply by 7 days = 33,180 grains per week

Add a 20% buffer for high-usage periods = 39,816 grains needed between regenerations

This math points directly to a 48,000-grain minimum capacity for Austin households — yet most residents install 32,000-grain systems that regenerate every 4-5 days instead of the optimal 6-7 day cycle. Over-frequent regeneration wastes salt, water, and resin life while increasing operating costs.

Mistake #4 — Overlooking Salt Efficiency

At 15.8 GPG, Austin water softeners regenerate 50-75% more often than systems in moderately hard water cities. An inefficient softener that uses 18 pounds of salt per regeneration will consume 40-50 bags annually in Austin conditions — compared to 15-20 bags for a high-efficiency unit. Over 10 years, the salt cost difference exceeds $800, not including the additional labor of hauling and loading salt bags.

Austin's extreme hardness makes efficiency crucial, not optional. High-efficiency systems like the SoftPro Elite HE use 6-8 pounds of salt per regeneration compared to 15-20 pounds for conventional units. The efficiency difference compounds rapidly under Austin's demanding 15.8 GPG conditions.

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

After evaluating Austin's water hardness of 15.8 GPG and the presence of chloramine and sediment in the local supply, one system consistently rises to the top for Austin homeowners: the SoftPro Elite HE Water Softener. This isn't a comfort upgrade for Austin residents — it's infrastructure protection engineered specifically for extremely hard water conditions that destroy lesser systems.

Salt-Based Ion Exchange

Salt-free "conditioning" systems cannot handle Austin's 15.8 GPG mineral load — they only attempt to change crystal structure while leaving all minerals in solution. At Austin's extreme hardness level, template-assisted crystallization and electromagnetic fields provide zero scale prevention. The SoftPro Elite HE uses true cation exchange resin to physically capture calcium and magnesium ions and replace them with sodium — the only technology that delivers genuinely soft water at 15.8 GPG.

The chemical process is precise and measurable. High-capacity resin beads hold millions of exchange sites where calcium and magnesium ions are trapped and sodium ions released. Post-softener hardness drops from Austin's 15.8 GPG to under 1 GPG — a 94% reduction that stops scale formation completely. Alternative technologies simply cannot achieve this level of mineral removal at Austin's extreme hardness concentration.

Demand-Initiated Regeneration (DIR)

At 15.8 GPG, resin capacity exhausts faster than in any moderately hard water city — making regeneration timing absolutely critical. The SoftPro's DIR system monitors actual water usage and mineral consumption, regenerating only when the resin approaches exhaustion. This prevents the twin disasters of Austin water softening: hard water breakthrough (under-regeneration) and salt/water waste (over-regeneration).

Traditional timer-based systems regenerate on fixed schedules regardless of actual usage — a recipe for failure in Austin's demanding conditions. DIR adjusts automatically for Austin's seasonal usage patterns, holiday periods, and irregular consumption while maintaining consistent soft water output. For Austin households consuming 4,740 grains daily, this precision timing is operationally essential, not merely convenient.

NSF/ANSI Standard 44 Certified Resin

Certification verifies that resin materials meet strict performance and safety standards — crucial for Austin residents already managing chloramine and sediment exposure. NSF Standard 44 testing confirms the resin removes hardness minerals without leaching contaminants back into treated water. At 15.8 GPG consumption rates, Austin households process 109,500 gallons annually through softener resin — making material safety and performance consistency non-negotiable.

Non-certified resin can contain manufacturing residues, inconsistent exchange capacity, or materials that degrade under high-mineral conditions. NSF certification provides Austin homeowners with third-party verification that the softening process itself doesn't introduce new water quality concerns while addressing the 15.8 GPG hardness problem.

Grain Capacity Options (32K, 48K, 64K, 80K)

Austin's 15.8 GPG demands careful capacity matching — and the SoftPro Elite HE offers the grain tiers that Austin households actually need. Using our sizing formula for a four-person Austin household:

4 people × 75 gallons × 15.8 GPG × 7 days × 1.2 buffer = 39,816 grains weekly

This calculation points to the 48K model as minimum capacity, with the 64K providing optimal 6-7 day regeneration cycles. Larger Austin households or those with high water usage should consider the 80K model. The availability of properly sized grain capacities distinguishes the SoftPro from big-box systems that top out at 32K — inadequate for Austin's extreme hardness conditions.

10-Year Warranty Protection

At 15.8 GPG, softener resin experiences heavy daily mineral loading that accelerates wear compared to moderate hardness cities. Austin's extreme conditions represent the upper limit of what ion exchange technology can handle long-term. A 10-year warranty provides Austin homeowners with protection during the years of highest mineral stress — covering resin replacement, control valve repair, and system performance guarantees that cheaper units cannot match.

Warranty coverage becomes especially valuable for Austin installations because the 15.8 GPG mineral load tests every component harder than normal operating conditions. SoftPro's decade-long commitment reflects confidence in the Elite HE's ability to withstand Austin's punishing water chemistry year after year.

Self-Cleaning Sediment Pre-Filter

Austin's distribution system sediment requires pre-filtration to protect resin life and control valve operation. The SoftPro Elite HE includes an integrated sediment filter that backwashes automatically during regeneration cycles — capturing Austin's iron oxide particles and pipe scale before they reach the resin tank. This feature addresses Austin's specific sediment challenges without requiring separate filter housing or manual cartridge changes.

Sediment protection extends resin life significantly in Austin conditions. Particles that bypass filtration embed in resin beds, creating flow restrictions and fouling exchange sites — problems that compound rapidly at 15.8 GPG mineral concentrations. The self-cleaning design maintains filtration effectiveness automatically, crucial for Austin's variable sediment levels during system maintenance periods.

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

6. How to Size Your Softener for Austin

Austin's 15.8 GPG requires precise sizing calculations — there's no margin for error at extreme hardness levels. Follow these steps to determine the correct SoftPro Elite HE capacity for your household:

Step 1: Count household members (include regular guests and seasonal residents)

Step 2: Multiply by 75 gallons per person per day (Austin average considering local climate)

Step 3: Multiply household gallons × 15.8 GPG = daily grain demand

Step 4: Multiply daily grains × 7 = weekly grain demand

Step 5: Add 20% buffer for high-usage days (Austin summers increase consumption)

Step 6: Match to SoftPro Elite HE grain tier (32K / 48K / 64K / 80K)

Here's the calculation worked out for a typical four-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 × 1.20 buffer = 39,816 grains needed

Result: 48K minimum capacity, 64K recommended for optimal 6-7 day regeneration cycles.

Austin's extreme hardness makes undersizing catastrophic. A 32K system would regenerate every 4-5 days, wearing out resin faster and increasing salt consumption. The 64K model provides the sweet spot for Austin conditions — adequate capacity with regeneration frequency that maximizes system life and efficiency.

7. Installation in Austin: What to Know

Austin requires licensed plumber installation for water softener systems, and the city's specific plumbing codes affect system placement and drainage connections. The City of Austin Plumbing Code mandates professional installation for any device connected to the main water line — DIY installation voids both manufacturer warranties and city compliance.

Proper placement follows a specific sequence: after the main water shutoff valve but before the water heater and any branch lines. In Austin's typical slab-on-grade construction, this usually means installation in the garage near the water heater, with the softener positioned to treat all household water except exterior irrigation lines. Austin's plumbing code requires a separate bypass valve and pressure relief considerations for the SoftPro's regeneration cycles.

Drain line requirements are specific to Austin's municipal drainage regulations. The regeneration discharge must connect to a laundry sink, floor drain, or standpipe — not directly to sewer lines. Austin's typical municipal water pressure ranges from 45-65 PSI, well within the SoftPro Elite HE's operating range of 25-80 PSI. Homes in West Austin hills or high-elevation areas may require pressure regulation for optimal performance.

Salt type selection is crucial at Austin's 15.8 GPG consumption rate. Evaporated salt pellets are mandatory for Austin installations — the highest purity salt available with minimal brine tank residue. Solar crystals contain impurities that create sludge problems in high-consumption systems, and rock salt is completely unsuitable for extreme hardness conditions. Austin residents should budget for 40-50 bags of evaporated pellets annually.

Check salt levels weekly during initial operation, then monthly once consumption patterns stabilize. At 15.8 GPG, salt consumption is 2-3 times higher than moderate hardness cities — Austin households typically use 8-12 bags every three months depending on system size and household usage patterns.

8. Maintenance Schedule for Austin Homeowners

Austin's 15.8 GPG creates accelerated maintenance requirements compared to moderate hardness cities — but following this schedule prevents expensive system failures and maintains peak performance.

Monthly Maintenance

Check salt level monthly — consumption is extremely high at Austin's 15.8 GPG mineral loading. Salt should maintain 6-8 inches above water level in the brine tank. Austin households consume salt 2.5 times faster than national averages due to frequent regeneration cycles.

Inspect for salt bridges — crusty formations above the water line that prevent proper brine formation. Austin's high mineral consumption creates conditions that promote salt bridging, especially during humid summer months when salt absorbs atmospheric moisture.

Verify bypass valve position — confirm the system remains in service position and hasn't been accidentally switched during any plumbing work or maintenance.

Quarterly Maintenance

Deep clean brine tank — Austin's accelerated salt consumption creates sediment buildup faster than moderate hardness cities. Remove salt, scrub tank walls, and refill with fresh evaporated pellets every three months.

Test post-softener water hardness — use test strips to confirm output remains under 1 GPG. Austin's extreme input hardness means any resin degradation shows up quickly in output quality.

Inspect sediment pre-filter — Austin's distribution system particles require more frequent attention than clean source water cities. Replace or clean filter media if flow rate decreases noticeably.

Annual Maintenance

Complete brine tank overhaul — disassemble, clean all components, and inspect for mineral buildup or component wear. Austin's high-cycle operation stresses brine systems more than typical installations.

Resin bed performance audit — if post-softener hardness creeps above 1 GPG despite proper salt levels, resin may need cleaning or replacement. Austin's 15.8 GPG loading accelerates resin fouling compared to moderate hardness conditions.

Regeneration cycle optimization — confirm timing and salt dose remain appropriate for current household usage. Austin families often adjust usage patterns seasonally, requiring system recalibration.

Five-Year Maintenance

Resin replacement evaluation — at Austin's extreme 15.8 GPG loading, assess whether resin output quality justifies replacement or system upgrade. High-GPG cities degrade resin faster than soft-water regions, and Austin represents the upper limit of ion exchange durability.

Austin residents should establish baseline hardness readings before installation and retest monthly during the first year to confirm optimal system performance under local extreme hardness conditions.

9. Frequently Asked Questions for Austin Residents

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

Austin's 15.8 GPG hardness exceeds EPA aesthetic guidelines but poses no direct health risks for most people. The minerals are calcium and magnesium — essential nutrients that actually contribute to daily dietary requirements. However, the extreme hardness creates significant infrastructure and financial problems that justify treatment. Austin Water meets all EPA primary health standards, but the mineral concentration causes appliance damage, increased utility bills, and skin/hair problems that affect quality of life.

10. Will a water softener remove Austin's chloramine disinfectant?

No — ion exchange softeners remove only hardness minerals (calcium and magnesium), not chemical disinfectants like chloramine. Austin residents concerned about chloramine taste, odor, or effects on plumbing components need a separate catalytic carbon filter designed specifically for chloramine removal. Standard activated carbon is ineffective against chloramine; only catalytic carbon or KDF media can break the chlorine-ammonia bond. Many Austin homeowners install both systems: softening for hardness and carbon filtration for chloramine.

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

Austin households typically consume 12-15 bags of evaporated salt pellets monthly with a properly sized SoftPro Elite HE system. This translates to 144-180 bags annually — significantly higher than moderate hardness cities due to Austin's extreme 15.8 GPG mineral loading. Monthly salt costs average $45-60 for evaporated pellets, but this expense prevents thousands in appliance damage and energy waste. Undersized systems use even more salt due to inefficient regeneration cycles.

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

Austin requires licensed plumber installation but typically no separate permit for residential water softener systems. The installation must comply with Austin's plumbing code, including proper drainage connections and backflow prevention. Austin Water prohibits softener discharge to storm drains or directly to sewer mains — regeneration waste must connect through approved drain connections. Commercial installations may require additional permits depending on system size and discharge volume.

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

Austin residents notice this effect dramatically because of the extreme contrast from 15.8 GPG to under 1 GPG after softening. The "slippery" sensation is actually your skin's natural oils that hard water minerals previously prevented you from feeling. Calcium and magnesium ions in Austin's water bind with soap to form sticky residue that coats skin — soft water allows soap to rinse completely clean, revealing the natural smoothness underneath. Most Austin residents adapt within 2-3 weeks and prefer the clean feeling over mineral-coated skin.

14. How quickly will I see results after installing a softener in Austin?

Austin homeowners notice immediate improvements in soap lathering and reduced spotting on dishes within 24-48 hours of installation. Existing scale deposits take longer to address — water heater efficiency improvements become measurable within 30-60 days as new scale formation stops and some existing deposits gradually dissolve. Skin and hair improvements typically appear within one week as mineral coating washes away. Appliance lifespan benefits accumulate over months and years of scale-free operation.

15. Can the SoftPro Elite HE handle Austin's water without a separate filter?

The SoftPro Elite HE effectively addresses Austin's 15.8 GPG hardness and includes sediment pre-filtration, but chloramine removal requires a separate catalytic carbon filter. Austin residents satisfied with chloramine taste and odor can install the softener alone and achieve excellent results for scale prevention, appliance protection, and soap efficiency. Those wanting comprehensive water treatment should pair the SoftPro with a whole-house catalytic carbon system for complete chloramine removal plus hardness control.

16. Final Verdict for Austin

Austin's water hardness of 15.8 GPG demands extreme-hardness-grade treatment — this is not a city where moderate solutions work. The combination of punishing mineral concentration, chloramine disinfection, and distribution system sediment creates a multi-layered challenge that destroys undersized or improperly specified water treatment systems within months.

The SoftPro Elite HE rises to the top for Austin homeowners because its demand-initiated regeneration prevents hard water breakthrough at extreme mineral loading, its grain capacity options include the 48K-80K tiers that Austin actually requires, and its 10-year warranty protects against the accelerated wear that 15.8 GPG conditions create. Lesser systems simply cannot handle Austin's mineral assault long-term without frequent repair, premature replacement, or chronic performance problems.

Austin residents should check current SoftPro Elite HE pricing and available grain capacities for properly sized Austin household protection. The investment pays for itself through prevented appliance damage, reduced utility bills, and eliminated soap waste — benefits that compound rapidly under Austin's extreme hardness conditions.

Like the Colorado River carving limestone canyons through the Texas Hill Country, Austin's 15.8 GPG water will methodically carve away your home's value unless you intervene with equipment built to match the challenge.
