Lewisville, Texas Water Quality and Treatment Guide
Residents of Lewisville, TX, are served primarily by two public water systems, the largest being the City of Lewisville system which supplies water to approximately 140,880 people. This water is drawn mainly from surface water sources including lakes, rivers, and reservoirs. Those living outside the coverage of these public utilities often rely on private wells. Understanding the characteristics of Lewisville’s water is key to ensuring it is safe, clean, and pleasant to use for your household needs.
Understanding Lewisville’s Water Hardness and Quality
Lewisville’s water is classified as very hard, frequently measuring between 11 and 25+ grains per gallon. The hardness comes primarily from dissolved minerals, a common feature in Texas due to limestone aquifers. Very hard water can lead to scale buildup in pipes and appliances, reducing efficiency and lifespan. It also affects soap performance and leaves mineral deposits on fixtures and dishes.
Since the City of Lewisville predominantly uses surface water, the supply is disinfected with chlorine or chloramine to ensure safety from microbial contamination. However, these disinfectants can sometimes create an off taste or odor and lead to the presence of disinfection by-products (DBPs). Seasonal changes may introduce sediment and increase turbidity (cloudiness), which affects water clarity and palatability.
Water Treatment Solutions for Lewisville Homes
To combat the high hardness and improve water quality, installing a water softener is highly recommended. A water softener exchanges hardness minerals like calcium and magnesium with sodium or potassium ions, preventing scale buildup and improving water feel. For Lewisville, a top pick is the DROP Smart Water Softener, known for its efficiency and advanced technology that can adapt to your household’s specific water usage and hardness levels.
Because of the surface water source and the use of chlorination, a carbon and sediment filter is also beneficial. These filters remove chlorine taste and odor, sediment, and reduce DBPs, bringing clearer, better-tasting water into your home. This stage is particularly helpful if seasonal turbidity affects your supply.
For tap water dedicated to drinking and cooking, a reverse osmosis (RO) system offers an additional layer of purification. RO systems remove dissolved solids and many contaminants to provide crisp, clean drinking water. Under-sink RO units are compact and highly effective for households concerned about water quality at the point of consumption.
Additional Considerations
If you rely on a private well, the water quality may vary greatly depending on the local aquifer and well construction. Testing your water annually is recommended to identify hardness levels, any microbial contamination, and other possible impurities.

FAQ: Water in Lewisville, TX
Q1: How hard is Lewisville’s water, and why does that matter?Lewisville’s water is very hard, often exceeding 11 grains per gallon. This hardness means mineral buildup in pipes and appliances, which can reduce efficiency and cause damage over time. Installing a water softener is the best way to prevent scaling and extend the life of your plumbing.
Q2: Are there any taste or clarity issues with Lewisville’s water?Yes, because Lewisville’s water is surface-supplied and disinfected with chlorine or chloramine, it may have a noticeable taste or odor. Additionally, seasonal sediment and turbidity can affect clarity. A carbon and sediment filter improves both taste and appearance significantly.
Q3: Should I consider reverse osmosis for my drinking water?An under-sink reverse osmosis system is a great choice if you want the cleanest possible drinking and cooking water. RO removes dissolved solids and many contaminants that a softener or carbon filter alone cannot. WaterSoftenerPlus ships directly to Lewisville, TX, so you can easily get these systems delivered and installed.
