Water Hardness Levels
Plough Row, Deeping St Nicholas, Spalding, South Holland, Lincolnshire
PE11 3EW South Holland District
Understanding water hardness and quality in your area
Curious about the water hardness levels in PE11 3EW area? Learn what the mineral content means for your home and appliances. Find out how it could impact your daily life and what you can do to manage it effectively.
Water hardness in the PE11 3EW postcode area has been recorded as having:
Moderately Hard to Hard Water
Observations
151-200 ppm: Moderately Hard - You'll see more limescale in kettles, showers, and taps. Cleaning becomes more of a chore, and you might want to consider using water softeners.
201-275 ppm: Hard Water – Expect limescale to build up quickly. This can damage appliances over time and make cleaning a real hassle. Water softening solutions are recommended.
What does this mean?
*Water hardness is measured in milligrams per litre (mg/L) or parts per million (ppm) of calcium carbonate (CaCO2). This tells you how much calcium and magnesium is present in the water.
In the UK, you'll often see water hardness expressed in degrees:
Degrees Clarke (°Cl)
This is a British measure where one degree Clarke is equivalent to 1 part of calcium carbonate per 70,000 parts of water.
These measures give you an idea of how "hard" or "soft" the water is, with higher numbers indicating harder water, which means more calcium and magnesium. If you ever get your water hardness tested, the results will likely be in one of these units.
Hardness/Softness Levels
Moderately Hard Water
Impact
At this level, limescale build-up is more pronounced. It can start affecting the efficiency and lifespan of appliances like washing machines, boilers, and dishwashers. Soap and detergent usage increases, and cleaning becomes more time-consuming.
What to Know
Households should regularly descale appliances and may benefit from installing a water softener. Businesses might face higher operational costs due to increased maintenance needs and should consider water treatment solutions to mitigate these effects.
Hard Water
Impact
Hard water causes significant limescale deposits, leading to frequent appliance breakdowns and reduced efficiency. For households, this means more cleaning and higher energy bills as appliances work harder. For businesses, particularly those in food service or healthcare, hard water can impact the quality of services, requiring frequent maintenance.
What to Know
Installing a water softener becomes highly advisable to protect plumbing and appliances. Regular descaling and maintenance are essential to avoid costly repairs and replacements.

How to reduce water hardness in your home
Understanding water hardness/softness levels helps you manage the impact of water on your home or business and choose the right water treatment solutions if necessary.
Reducing water hardness in your home can significantly improve the lifespan of appliances, reduce energy costs, and make cleaning easier. One of the most effective ways to manage hard water is by installing a water softener. These systems work by exchanging calcium and magnesium ions, which cause hardness, with sodium ions, effectively "softening" the water before it enters your home's plumbing.
For those looking for a less permanent solution, water conditioners can really help. These devices don’t remove the minerals but alter their structure, preventing them from forming limescale. Alternatively, you can add water softening tablets or salt to your washing machine to help protect clothes and your machine from the effects of hard water.
For smaller appliances, like kettles and coffee machines, regular descaling with vinegar, citric acid, or a commercial descaler can prevent limescale build-up in the long run.
