What Makes Lytham St Annes's Water Unique?

Local geology and source profile

Source: MixedTDS: 187.2 mg/LpH: 7.4

Lytham St Annes, the seaside resort town on the Fylde coast in Lancashire between Blackpool and the Ribble estuary, is supplied by United Utilities from the Thirlmere Lake District aqueduct and the River Wyre catchment. The Thirlmere aqueduct delivers very soft water from the Borrowdale Volcanic catchment of the central Lake District — one of the softest water supplies in England — and the Wyre from Stocks Reservoir in the Forest of Bowland drains the Carboniferous Millstone Grit moorland of the Bowland Fells, also producing soft water. United Utilities distributes through the Fylde coast supply network, serving Lytham St Annes with this consistently soft north Lancashire supply. The Fylde coast receives very limited hard groundwater blending and is served primarily by soft upland aqueduct supply.

Lytham St Annes's soft water — 76.5 mg/L (5.4°Clark) — reflects the Thirlmere Lake District aqueduct and Bowland Fells River Wyre supply dominant on the Lancashire Fylde coast. The Drinking Water Inspectorate (DWI) classifies this supply as soft.

Limescale is very minor in Lytham St Annes. At 76.5 mg/L, limescale builds slowly — kettles need descaling every two to three months. Combi-boiler heat exchangers accumulate minimal deposits; annual servicing is routine. Showerheads and taps remain largely clear. Washing-up liquid lathers very well with the soft Fylde coast supply. Limescale is not a significant domestic concern for Lytham St Annes households on the United Utilities Thirlmere and Wyre supply.

Geology & Source: Supplied by United Utilities from Thirlmere Lake District aqueduct and River Wyre — Lytham St Annes's Fylde coast position south of Blackpool draws on United Utilities' very soft Thirlmere-dominant Fylde coast supply, producing soft water at 76.5 mg/L (5.4°Clark).
