Photographed looking NE. Site contains old steam driven pumping station and water softening plant, plus modern electric pumps for raising water from the chalk aquifer.
I'm a little confused by the comment on SU4924 : Twyford Waterworks that the pumping station "until 1969 applied lime to soften the water" - as lime would tend to have the opposite effect of hardening the water. Anyone know better or have any more details ?
