Cleburne Water Quality: What’s in Your Water, Where It Comes From, and What to Do About It

Section 1: Why Cleburne and Johnson County Water Has a Specific Profile

If you live in Cleburne or the surrounding Johnson County area, your tap water comes from one of two distinct public water systems — and which one serves your home depends entirely on your address. These two utilities have genuinely different water sources, different treatment methods, and different chemistry signatures. Understanding which system serves you is the first step toward knowing what’s actually in your water.

City of Cleburne Water Utilities (PWS ID: TX1260003), operated by City of Cleburne Public Works, Water and Wastewater Services, supplies approximately 30,573 residents inside the Cleburne city limits. The city draws from a blend of surface and groundwater sources: Lake Pat Cleburne, Lake Aquilla in Hill County, and Trinity Aquifer wells in the Twin Mountain–Travis Peak formation. The city uses chloramine as its primary year-round disinfection method, with an annual free-chlorine conversion period for system flushing.

Johnson County Special Utility District (JCSUD, PWS ID: TX1260018) serves a much larger territory — approximately 65,427 people across roughly 324 square miles spanning Johnson, Hill, Tarrant, and Ellis counties. JCSUD covers rural Johnson County, the city of Joshua, north Cleburne exurbs, and portions of Keene, Godley, Rio Vista, and Grandview. JCSUD blends 70% purchased surface water (from Lake Granbury and the City of Mansfield, which in turn purchases from Tarrant Regional Water District reservoirs) with 30% Trinity Aquifer groundwater.

Both utilities fully meet all federal Safe Drinking Water Act standards and are regulated by the Texas Commission on Environmental Quality (TCEQ).

Circle T Plumbing & Water Quality is the only plumbing company serving Cleburne and Johnson County leading with combined plumbing and water quality expertise. Our Texas Responsible Master Plumber (License #M45785, issued by the Texas State Board of Plumbing Examiners) tests and treats both City of Cleburne and JCSUD water profiles every week. We wrote this guide because accurate, locally specific water information for this area has simply not existed in one place — until now.

Section 2: City of Cleburne Water Utilities — Sources and Treatment

City of Cleburne Water Utilities (PWS TX1260003) is operated by City of Cleburne Public Works, Water and Wastewater Services. The utility serves the Cleburne city limits and draws from three named source waters.

Lake Pat Cleburne is a surface reservoir named after the city itself. It is shallower and biologically more productive than the large reservoirs serving Fort Worth — characteristics that contribute to higher dissolved organic carbon in the raw water. That organic carbon load is relevant to the disinfection byproduct profile discussed in Section 4.

Lake Aquilla, located in Hill County, serves as a supplementary surface water source. It provides additional supply capacity, particularly during periods when Lake Pat Cleburne’s levels or water quality require supplementation.

Trinity Aquifer wells in the Twin Mountain–Travis Peak formation provide groundwater supplementation. This blend of surface and groundwater is a meaningful distinction from Fort Worth’s water supply, which is 100% surface water from seven reservoirs. The groundwater contribution introduces different mineral characteristics — particularly hardness — that the surface-only Fort Worth profile does not carry in the same way.

Primary disinfection: chloramine. The City of Cleburne uses chloramine (a bond of chlorine and ammonia) as its year-round disinfection method. Chloramine is more stable in distribution systems than free chlorine alone, which is why many utilities of this size use it. For homeowners, the practical implication is filter selection: chloraminated water requires catalytic activated carbon for effective removal — standard granular activated carbon (GAC) does not break the chlorine-ammonia bond effectively.

Annual free-chlorine conversion. Once per year — typically in the fall — the City of Cleburne converts its distribution system from chloramine to free chlorine for a period of approximately three to six weeks. This practice reduces nitrification and clears biofilm from the distribution system. It is confirmed by City of Cleburne public notice (November 2020) and referenced in City Council Regular Meeting Minutes (March 12, 2024). Homeowners sometimes notice a change in their water’s taste or smell during this window. It is a planned operational procedure — not an indication of a water quality problem. Homeowners on whole-home catalytic carbon systems will continue to perform well during the conversion period; those relying on standard GAC pitcher or faucet filters may notice temporarily improved performance during free-chlorine weeks before reverting to inadequate performance once chloramination resumes.

City of Cleburne Water Utilities is in compliance with all federal drinking water standards, with the most recent EPA assessment covering April through June 2024.

Section 3: Cleburne Water Hardness — What It Means for Your Home

Hard water is water that contains elevated concentrations of dissolved calcium and magnesium minerals. Hardness is measured in milligrams per liter (mg/L) or parts per million (ppm) as calcium carbonate (CaCO₃), or in grains per gallon (gpg), where 1 gpg is approximately 17.1 ppm.

The Water Quality Association classifies hardness as follows: 0–60 mg/L (soft), 61–120 mg/L (moderately hard), 121–180 mg/L (hard), and above 180 mg/L (very hard). In gpg terms: 0–3.5 gpg is soft, 3.5–7 gpg is moderately hard, 7–10.5 gpg is hard, and above 10.5 gpg is very hard.

City of Cleburne water draws from Trinity Aquifer wells in addition to surface reservoirs. Regional water in this part of North Texas is consistently hard. Trinity Aquifer–influenced systems typically test in the 8–12 gpg range, classified as hard to very hard. Confirming the exact number for your specific address requires either (a) the most recent City of Cleburne Consumer Confidence Report or (b) an on-site water test — because the actual hardness at your tap can vary from utility-level averages depending on which source the city is drawing from at any given time and the mineral pickup along your distribution line.

Hard water is not a health concern. This is important to state clearly. Calcium and magnesium are naturally occurring minerals with no established health risk at the levels found in municipal water. The consequences of hard water are entirely practical: scale buildup on faucets, showerheads, and tile; white film on dishes and glassware; reduced soap lathering; scale accumulation inside water heaters that reduces heating efficiency and can shorten equipment life; and accelerated wear on dishwashers, washing machines, and ice makers.

The testing-to-treatment connection is straightforward. A water test confirms the actual hardness level in grains per gallon at your tap. That number is what a water softener installer uses to size a system correctly — a softener sized for 8 gpg will not regenerate efficiently if your water is actually 12 gpg. Sizing matters for both performance and salt consumption. Circle T Plumbing & Water Quality diagnoses your actual hardness before recommending any equipment.

Section 4: Disinfection Byproducts — Cleburne’s Profile Differs from Fort Worth’s

Disinfection byproducts (DBPs) are compounds that form when chlorine or chloramine reacts with naturally occurring organic matter in source water. The two regulated families are total trihalomethanes (TTHMs) and haloacetic acids (HAAs). Both are formed whenever a utility disinfects water that contains dissolved organic carbon — a characteristic of all surface water supplies.

The U.S. EPA has established Maximum Contaminant Levels (MCLs): TTHMs at 80 ppb and HAA5 at 60 ppb. Both City of Cleburne and City of Fort Worth are well below these federal limits.

Cleburne’s documented DBP levels (EWG Tap Water Database, PWS TX1260003):

• TTHMs: 31.5 ppb (federal MCL: 80 ppb)
• HAA5: 24.3 ppb (federal MCL: 60 ppb)
• HAA9: 53.4 ppb (no federal limit applies to HAA9)

Fort Worth’s documented DBP levels for comparison (PWS TX2200012):

• TTHMs: 13.9 ppb
• HAA5: 7.98 ppb

Cleburne’s DBP levels are roughly twice Fort Worth’s, despite both systems using chloramine as their primary disinfection method. Three factors explain this difference. First, City of Cleburne is a smaller system with less robust pre-treatment capacity for organic carbon reduction than the Fort Worth Water Department’s large-scale infrastructure. Second, Lake Pat Cleburne is shallower and warmer than Fort Worth’s reservoirs, which supports more dissolved organic carbon in the raw water before treatment begins. Third, the annual free-chlorine conversion period produces short-term spikes in DBP formation.

All DBPs in Cleburne water remain below federal MCL standards. The Environmental Working Group (EWG) publishes voluntary health guidelines that are substantially more conservative than federal limits — Cleburne’s TTHMs (31.5 ppb) exceed the EWG voluntary guideline of 0.15 ppb, and HAA5 (24.3 ppb) exceeds the EWG guideline of 0.1 ppb. Some homeowners use the EWG comparison as a reason to install additional point-of-use filtration even when their utility is fully compliant with federal standards. We present both numbers and let you evaluate what matters for your household — we do not editorialize the gap.

For homeowners who want to reduce DBP exposure at the drinking water tap, reverse osmosis is the most effective consumer technology available for this purpose.

Section 5: Johnson County SUD — A Different Water System for Rural Cleburne and Joshua

Johnson County Special Utility District (JCSUD, PWS TX1260018) is a distinct utility with a meaningfully different water chemistry profile from the City of Cleburne system. Understanding JCSUD is essential for Circle T Plumbing & Water Quality’s rural ICP customers — the homeowning families in Joshua, Keene, Godley, Rio Vista, Grandview, and the north Cleburne exurbs who are often lumped into generic “Cleburne water” content that doesn’t actually describe their water at all.

System overview. JCSUD serves approximately 65,427 people across roughly 324 square miles in Johnson, Hill, Tarrant, and Ellis counties. The district is headquartered at 2849 Highway 171 South, Cleburne, TX 76033 (phone: 817-760-5200; website: jcsud.com). Service territory includes rural Johnson County, the city of Joshua, north Cleburne exurbs, and portions of Keene, Godley, Rio Vista, and Grandview.

Source water blend. JCSUD’s water comes from two fundamentally different origins: approximately 70% purchased surface water (from Lake Granbury and the City of Mansfield, which in turn draws from Tarrant Regional Water District reservoirs) blended with approximately 30% Trinity Aquifer groundwater from the Twin Mountain–Travis Peak formation. This hybrid is genuinely different from either city-only system. Rural Johnson County homes on JCSUD water have a chemistry profile that reflects both groundwater mineral pickup and surface water disinfection byproduct formation.

Disinfection. JCSUD uses free chlorine (rather than chloramine) as its primary disinfection method — consistent with the DBP profile and typical practice for blended systems at this scale. For homeowners selecting water filtration, standard activated carbon is likely adequate for free-chlorine systems (unlike chloramine systems, which require catalytic carbon).

Naturally occurring trace contaminants. The Trinity Aquifer groundwater portion of JCSUD’s supply introduces naturally occurring trace compounds that are characteristic of the geology of this formation. Both are below federal limits and both exceed the more conservative EWG voluntary guidelines:

• Arsenic: detected at 0.130 ppb (federal MCL: 10 ppb; EWG voluntary guideline: 0.004 ppb)
• Radium (combined): detected at 0.15 pCi/L (federal MCL: 5 pCi/L; EWG voluntary guideline: 0.05 pCi/L)

JCSUD meets all federal Safe Drinking Water Act standards. These are characteristics of Trinity Aquifer geology — natural occurrence from mineral-bearing rock formations, not contamination from human activity. That distinction matters: your utility has not failed to treat your water; the geology of the aquifer introduces these minerals at trace levels.

For JCSUD homeowners who want to reduce arsenic and radium at the drinking water tap, reverse osmosis is the only consumer technology that reliably reduces both. Carbon filtration and water softeners do not address either compound. This single fact often reframes the conversation for rural Johnson County and Joshua homeowners: the question isn’t whether to filter — it’s which technology matches what’s actually in their water.

Section 6: What a Cleburne Water Test Reveals

Utility-level data — the numbers in this guide — describes what the public water system delivers on average across the distribution network. Your home’s tap water may vary from those utility averages for several reasons: older pipes and plumbing materials, distribution distance from treatment facilities, seasonal variation in source blending, and the specific plumbing characteristics inside your home. An on-site water test tells you what’s actually at your tap — not what’s average across the system.

What Circle T Plumbing & Water Quality tests for in Cleburne and Johnson County homes:

For City of Cleburne addresses: chloramine presence (or free chlorine during the annual conversion window), mineral hardness in grains per gallon, total dissolved solids (TDS), pH, and disinfection byproduct indicators. For JCSUD-served addresses, the panel expands to include baseline testing for naturally occurring concerns where appropriate.

Why seasonal testing matters for City of Cleburne homes. The annual free-chlorine conversion — typically in the fall — is a real-world reason to test in different seasons if you’ve noticed taste or odor changes in your water. Water that tastes slightly different in October or November than it does in July is not a malfunction; it reflects the operational switch from chloramine to free chlorine. A test taken during the conversion window will show a different disinfectant residual than a test taken in July. If you’ve noticed seasonal variation, a test during that period is the most informative one you can run.

Why baseline testing is particularly valuable for JCSUD addresses. For newer construction in Joshua, Godley, or the rural north Cleburne exurbs, the homeowner often has no prior water quality comparison point. A baseline test establishes what’s normal for that address — which makes future variation detectable and gives you a factual foundation for any treatment decisions.

Testing at Circle T follows the Quality Beyond Compare Method: we test, explain what we find in plain English, and present honest options. You decide. Schedule a Cleburne water quality assessment through our Cleburne territory service.

Section 7: Water Quality Solutions for Cleburne and Johnson County Homes

The water chemistry documented in this guide points toward specific treatment technologies for specific problems. Here is how Circle T Plumbing & Water Quality maps the Cleburne and JCSUD water profiles to the five water quality services we provide.

Water Quality Testing

Testing is the diagnostic entry point for every water quality conversation. For Cleburne and JCSUD addresses alike, an on-site test confirms the actual hardness in grains per gallon at your tap, documents the disinfectant residual type and level, establishes a pH and TDS baseline, and — for JCSUD-served addresses — provides a starting reference for naturally occurring compound levels. Water quality testing is included as the first step on every filtration, softener, or reverse osmosis service visit. Without a test, equipment sizing and technology selection are guesswork — so we start with a Cleburne water quality assessment, explain results in plain English, and present honest options. No pressure.

Water Filtration

City of Cleburne water uses chloramine as its primary disinfection method year-round. For chloramine systems, catalytic activated carbon is the appropriate filter media — not standard granular activated carbon (GAC). Standard GAC cartridges found in retail pitcher filters and basic faucet filters adsorb free chlorine effectively but do not break the chlorine-ammonia bond in chloramine. Homeowners on Cleburne city water who have purchased over-the-counter filtration and still notice a chemical taste or odor are frequently experiencing exactly this mismatch: the filter is the wrong technology for the disinfectant. Circle T Plumbing & Water Quality, an authorized Charger Water Products installer, installs catalytic carbon whole-home filtration systems appropriate for chloramine water — a distinction that matters. For Cleburne territory service, see our Cleburne city service page for filtration recommendations specific to your address.

Water Softener Installation

Both City of Cleburne and JCSUD water are influenced by Trinity Aquifer geology, and regional Trinity Aquifer–influenced systems consistently test in the hard range. Scale on faucets, showerheads, and tile, white deposits on dishes, and accelerated water heater wear are the visible signs. Correct water softener sizing requires an on-site grain demand calculation — a softener sized too small will not protect your home’s plumbing; one sized too large wastes salt and water during regeneration. Circle T Plumbing & Water Quality, as an authorized Charger Water Products installer, sizes and installs whole-home softening systems based on your actual test results. For Cleburne territory service, see our Cleburne city service page for softener recommendations matched to your address.

Reverse Osmosis

Reverse osmosis is the highest-level point-of-use drinking water treatment available for residential homes. For City of Cleburne addresses, an RO system addresses the elevated DBP profile — TTHMs at 31.5 ppb and HAA5 at 24.3 ppb are well within federal limits, but some homeowners prefer to reduce them further at the drinking water tap. For JCSUD-served addresses, RO is the only consumer technology that reliably reduces both arsenic and radium — carbon filtration and water softeners do not address either. A properly sized under-sink RO system eliminates bottled water dependence and provides filtered water on demand. Circle T installs Charger Water Products RO systems sized for residential applications. For Cleburne territory service, see our Cleburne city service page for RO recommendations specific to your address. License #M45785.

Commercial Water Treatment

The same water chemistry expertise we apply to Cleburne and Johnson County residential homes extends to commercial accounts — restaurants, healthcare facilities, office buildings, and light industrial operations in the area. Water quality requirements for commercial applications vary by use, regulatory context, and process needs. Commercial water treatment is available throughout Circle T Plumbing & Water Quality’s Cleburne service territory.

Section 8: Cleburne Water Quality by Service Area — City vs. Rural Coverage

The city/rural utility split in Cleburne’s service area is something most water quality content ignores. It matters for treatment recommendations.

Inside Cleburne city limits: City of Cleburne Water Utilities (PWS TX1260003). Source: Lake Pat Cleburne + Lake Aquilla + Trinity Aquifer wells. Disinfection: chloramine year-round, with annual free-chlorine conversion (typically fall). Key characteristics: elevated DBP profile vs. Fort Worth, regionally typical hardness, catalytic carbon required for effective chloramine filtration.

Outside Cleburne city limits — Joshua, north exurbs, Keene, Godley, Rio Vista, Grandview, rural Johnson County: Johnson County Special Utility District (PWS TX1260018). Source: 70% purchased surface water (Lake Granbury + City of Mansfield) + 30% Trinity Aquifer wells. Disinfection: free chlorine. Key characteristics: naturally occurring arsenic (0.130 ppb) and radium (0.15 pCi/L) from Trinity Aquifer geology — both below federal MCL, both above EWG voluntary guidelines.

If you’re not sure which utility serves your address, check your water bill (the utility name is listed) or call City of Cleburne Public Works at 817-645-0946 or JCSUD at 817-760-5200. Some addresses near the city/rural boundary may fall on either system depending on when the neighborhood was developed and which utility extended service first.

Cleburne vs. Fort Worth. Fort Worth water comes from a different system entirely — 100% surface water drawn from seven reservoirs managed by the Fort Worth Water Department and supplied in part by Tarrant Regional Water District. Both Fort Worth and Cleburne use chloramine as their primary disinfection method, but the source profiles, hardness levels, DBP concentrations, and operational practices (including Cleburne’s annual free-chlorine burn) differ meaningfully. For Fort Worth-area water quality information, see the Fort Worth Water Quality Guide.

For Cleburne territory service, Circle T Plumbing & Water Quality serves both City of Cleburne and JCSUD customers across Johnson County. Our Cleburne city service page addresses the specific chemistry of both utilities — filtration, softener, and reverse osmosis recommendations matched to your address and water profile.
