Tap water delivered throughout Upland by the City of Upland Water Division and the San Antonio Water Company meets all state and federal primary drinking water standards, but it carries a significant mineral load. Water drawn from the local Chino Basin groundwater aquifer and blended with state water project imports contains high concentrations of dissolved calcium, magnesium, and chlorine disinfectant byproducts, resulting in water hardness between 180 and 280 PPM (10 to 16 grains per gallon). This hard water creates chalky white scale on shower glass, crusts faucet aerators, and shortens the lifespan of water heaters and dishwashers. Our plumbers install high-capacity whole-home filtration and water conditioning systems tailored to local water chemistry.
According to published annual Consumer Confidence Reports, Upland tap water is classified as 'hard' to 'very hard'. As water percolates through regional limestone bedrock and alluvial soil, it dissolves mineral salts. When this water is heated inside your home's water heater or evaporates on fixtures, the minerals precipitate out as stubborn calcium carbonate crust. Additionally, residual chlorine added for municipal disinfection leaves a chemical taste and drying sensation on skin and hair.
We offer layered water treatment strategies based on your family's priorities. Whole-house carbon filtration and ion-exchange softening treat all water entering your home at the main point of entry, protecting every pipe, shower, and appliance. For kitchen cooking and drinking, we install multi-stage reverse osmosis (RO) systems under the sink that remove up to 99% of dissolved solids, heavy metals, and micro-contaminants.
Installing a whole-house filtration or softening system requires cutting into your primary domestic supply line before it splits to interior fixtures. Our technicians install the equipment in your garage or utility space, configure full-port three-valve bypass manifolds for effortless servicing, run dedicated drain lines with air gaps, and ensure outdoor garden irrigation lines remain unsoftened to preserve landscaping and save salt.
Unaddressed plumbing wear damages building materials, increases water waste, and risks sudden structural failures.
We install durable, commercial-grade materials designed for long-term reliability in the Cucamonga Valley.
Yes. Upland tap water averages between 180 and 280 parts per million (PPM) of total hardness, which equates to 10 to 16 grains per gallon. Anything above 7 grains per gallon is classified as hard water by the Water Quality Association.
