City of Plano Water Company

The City of Plano is committed to providing residents with safe, high-quality municipal water that meets the strictest regulatory standards. Our water system proudly maintains a "Superior" rating from the Texas Commission on Environmental Quality (TCEQ), exceeding both state and federal requirements. We acknowledge the North Texas Municipal Water District (NTMWD) for their excellence in water production.

This report provides essential information about your municipal water and our ongoing efforts to ensure its safety. It summarizes the quality of water we deliver to our customers, using data from the most recent EPA-mandated testing.

Where does our water come from?
The City of Plano purchases surface water from the North Texas Municipal Water District (NTMWD), which serves over 1.3 million people across numerous communities in 10 counties. NTMWD obtains raw water primarily from Lavon Lake and processes it at the Wylie Water Treatment Plant. Additional water sources include:

• Lake Texoma on the Texas-Oklahoma border
• East Fork Water Reuse Project along the Trinity River
• Jim Chapman Lake (formerly Cooper Lake)
• Lake Tawakoni

NTMWD manages six water treatment facilities, 576 miles of transmission pipelines, and 14 pump stations. To meet future demand, they're constructing the Lower Bois d'Arc Creek Reservoir in Fannin County, which will provide 120,500 acre-feet of water annually.

Potential Contaminants in Water Sources
All water sources (tap and bottled) may contain some level of contaminants. Their presence doesn't necessarily indicate a health risk. For information about contaminants and potential health effects, call the EPA Safe Drinking Water Hotline at 800-426-4791.

Source water may contain:

• Microbial contaminants from sewage treatment, septic systems, agricultural operations, and wildlife
• Inorganic contaminants like salts and metals, which may occur naturally or result from urban runoff, wastewater discharges, or farming
• Pesticides and herbicides from agriculture, urban runoff, and residential use
• Organic chemical contaminants from industrial processes, petroleum production, gas stations, and septic systems
• Radioactive contaminants that may occur naturally or result from oil/gas production and mining

Secondary Constituents
Elements like calcium, sodium, or iron can affect taste, color, or odor but are regulated by Texas rather than the EPA. These aesthetic issues don't necessarily indicate health concerns.

Cryptosporidium Testing
NTMWD has tested both lake water and treated water for Cryptosporidium for several years, finding it absent in all samples. This protozoan affects digestive systems and is present in water contaminated with sewage or animal waste. While no specific effective treatment exists, people with healthy immune systems typically recover.

2. Does City of Plano test its tap water?
   Yes. Like every public water system, City of Plano must test its water under the federal Safe Drinking Water Act and publish an annual water quality report (Consumer Confidence Report). Ask the utility for the latest report or look for it on its website.

4. Does City of Plano water contain lead?
   Water usually leaves the treatment plant without lead. Lead can enter tap water from older service lines, solder and brass fixtures inside homes, especially when water sits in the pipes. Run the tap before drinking if water has been sitting, and ask the utility about lead testing and service line records.
5. Is City of Plano water hard?
   Hardness depends on the source and changes over time. The annual water quality report lists hardness, or you can test it at home. If it is above about 7 grains per gallon, a water softener sized to your measured hardness will stop scale and spotting.
