Little Lever Water Hardness & Quality Report (2026)

United Utilities supplies Little Lever, the Borough of Bolton village between Farnworth and Radcliffe on the Irwell river plain — a small but long-established community on the edge of the Bolton and Bury industrial corridor, with a village centre, local schools, and a residential character that contrasts with the heavier industrial heritage of the surrounding communities — from Pennine upland reservoirs on Carboniferous Millstone Grit moorland in the south Bolton–Radcliffe supply zone, treated at Franklaw Water Treatment Works near Preston. At 63 mg/L (4.4°Clark), Little Lever's water is soft — consistent with the impermeable Carboniferous Millstone Grit (Namurian) and peat moorland of the south Lancashire Pennine upland that contributes very little calcium to the reservoir supply.

Little Lever lies in the south Bolton Irwell valley plain where United Utilities delivers supply from Pennine upland reservoirs on the Millstone Grit moorland above Bolton and Bury. The impermeable gritstone and peat moorland catchment yields low mineralisation water, producing 63 mg/L with TDS 140.7 mg/L — soft water with a moderate TDS/hardness ratio (2.23) characteristic of the United Utilities south Bolton–Radcliffe distribution zone, comparable to Farnworth and Radcliffe in the same upland reservoir supply corridor.

At 63 mg/L, limescale is a minimal household concern in Little Lever. Kettle descaling every two to three months is typically all that is required. The combi-boiler has very low scaling risk. Washing-up liquid lathers readily with small quantities. Taps and shower heads accumulate very little limescale; a quarterly wipe keeps fixtures clean. Little Lever's soft supply reflects the Millstone Grit moorland character of the south Lancashire Pennines — clean, soft water from the gritstone upland above Bolton delivering low-mineralisation supply to households in this quietly residential village on the Irwell plain.
