Your Local Water Profile

Here are the facts about Suisun's municipal water supply:

  • Water Hardness: 5.7 GPG (97.5 PPM)
  • Classification: Moderately Hard
  • Primary Source: Municipal supply, calculated from calcium and magnesium content.

This hardness level is slightly above the U.S. average of roughly 5 GPG. A single grain per gallon (GPG) is equivalent to one grain (about the weight of a paperclip) of dissolved rock dissolved in one gallon of water. For Suisun residents, that means your water carries almost six times that amount.

The Real Cost of Moderate Hardness

Even moderate hardness takes a toll on your home. Over a year, an average Suisun household will see 1.4 lbs of calcium carbonate scale build up inside pipes and appliances. This rock-like deposit is a hidden tax on your budget.

  • Gas & Electric Water Heaters: Scale acts as an insulator, forcing your heater to work harder to heat water. This inefficiency can increase your Pacific Gas & Electric Co bill. The lifespan of a water heater, normally 12-15 years, is reduced to just over 12 years in these conditions.
  • Dishwashers & Washing Machines: Hard water minerals bind with soaps and detergents, reducing their effectiveness. You may need up to 30% more detergent to get clothes and dishes clean, and hard water residue leaves spots on glassware.
  • Kettles & Coffee Makers: The white, chalky scale you see in your electric kettle is a direct visual of what's happening inside your larger, more expensive appliances.

How Hard Water Affects Your Family

While municipal water in Suisun is safe to drink, its mineral content impacts daily life. Hard water minerals react with soap to form a film, rather than a rich lather. This residue can lead to:

  • Dry, itchy skin and scalp
  • Dull, brittle hair that's difficult to manage
  • A feeling of residue on your skin after showering

For families with infants, preparing baby formula with hard water can be a concern due to the mineral concentration, though it is not considered a direct health hazard.

Filtration That Makes Sense for Suisun

With moderately hard water at 5.7 GPG, a full-scale whole-house water softener isn't always a cost-effective first step. The economics are clear: a whole-house softener (~$1,500 installed) pays for itself in a staggering 23.8 years through savings of only $63/year. For most households, more targeted solutions are practical.

  • Best for Drinking Water: A quality pitcher filter (like Brita or PUR) or a faucet-mount filter will effectively remove the taste associated with minerals and reduce contaminants.
  • Best for Budget: Start with a pitcher filter. It addresses the most common complaint—taste—without a major investment.
  • Whole-House Option: If you're committed to protecting all your appliances, a salt-free water conditioner can reduce scale buildup without the expense and maintenance of a traditional softener.

Consider that many families spend $600-$900 annually on bottled water. An under-sink reverse osmosis (RO) system can eliminate that cost entirely while providing premium drinking water.

Frequently Asked Questions

Is 5.7 GPG water considered 'bad' for Suisun City?

No, it's not bad from a health perspective. It's safe to drink. However, 5.7 GPG is 'moderately hard,' which means it will cause noticeable scale buildup on appliances, soap scum in showers, and can affect skin and hair over time.

Do I really need an expensive whole-house system for moderately hard water?

For most Suisun homes, no. The data shows a payback period of nearly 24 years for a traditional softener, which isn't practical. A high-quality pitcher or faucet-mount filter is usually sufficient to improve taste and reduce mineral-related issues for drinking and cooking.

Why does my PG&E bill go up with hard water?

Hard water creates mineral scale inside your water heater. This scale forces the heating element (electric) or gas burner to run longer to heat the same amount of water, consuming more energy and increasing your utility bill from Pacific Gas & Electric Co.
