Wessex Water: water quality and hardness

Wessex Water supplies drinking water and provides wastewater services in the South West. Check which service it provides at your property: the name on a wastewater bill may differ from your drinking-water supplier.

An independent WaterGrade guide. Local readings vary by source area and date.

Restrictions: Check the current hosepipe ban status for Wessex Water

How Wessex Water reports on your water

Its postcode results show hardness in several appliance units and link to a fuller quality PDF. The PDF can contain qualified results and historical exceedance information that is not visible in the short website summary.

Keep the full PDF’s quality year separate from any undated hardness summary. We retain those publications separately and do not infer hardness where the PDF omits it.

These count our verified records, including historical areas. They are not the company’s current total zones, population coverage or a quality score.

Four full 2025 quality PDFs are verified: Monkswood, Batheaston, Salisbury and Maundown Central. Other retained area summaries have more limited detail. This source requires browser review.

Is the water hard or soft?

Check the figure for your supply zone. A company can deliver water from different sources, so a single average can give the wrong appliance setting for your home. Hardness describes dissolved minerals; it is not a safety rating.

Our local cards use mg/l as calcium carbonate (CaCO₃). Keep the original unit and reporting period when comparing results. Supplier labels can use different hardness bands.

What do the quality results tell you?

Read each parameter with its units, sample count, range and reporting period. A mean below a reference limit does not establish that every sample complied. A “less than” result is not an exact concentration.

Company-wide performance, local zone results and water at an individual tap are different levels of information. Historical exceedances need the supplier’s investigation context; they are not automatically a current incident.

Has the water changed over time?

Compare the same named area, metric, units and kind of reporting period. A new download date is not a new sample. Renamed zones or overlapping rolling windows need extra care before drawing a trend.

We do not yet hold a comparable annual hardness series for this supplier. We do not draw a trend from a single edition or overlapping rolling reports.

Open a local report and choose “Save on this browser” to return later. Saved reports can be checked for revised published details; this is not an emergency-alert service.
