Statement of Special Interest

There are several other structures associated with the former Glasgow Corporation Water Works Loch Katrine scheme, including similar aqueducts, listed in Aberfoyle parish, and also in Buchanan and Callandar Parishes.

Glasgow's Lord Provost Robert Stewart (1810-66) was the driving force behind the search to find a clean source of water for Glasgow, and so to reduce the rate of illness and death through water-borne diseases. Loch Katrine was identified as a suitable supply, and an Act of Parliament approving the scheme was finally passed in 1855 after two initial rejections, including one from the Admiralty who were worried that the works would result in the silting-up of the Forth.

Work began on the scheme in 1856, under the supervision of John Bateman; the conduit which carries the water between Loch Katrine and Glasgow runs mostly underground and was excavated by hand with the aid of gunpowder; the spoil was brought to the surface through intermittently placed shafts (see separate listing). The scheme was opened by Queen Victoria in 1859.

Further Acts of Parliament in 1882 and 1885 allowed for the construction of a second conduit and the raising of the loch level. This work was not completed until 1901, under engineer James Morrison Gale. A brass plaque on the wall of the intake records a further raising of the loch level between 1919 and 1929.

Upgraded C(S) to A following the thematic review of Loch Katrine water supply system in 2008.

About Listed Buildings

Listing is the way that a building or structure of special architectural or historic interest is recognised by law through the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997.

We list buildings of special architectural or historic interest using the criteria published in the Historic Environment Scotland Policy Statement.

The information in the listed building record gives an indication of the special architectural or historic interest of the listed building(s). It is not a definitive historical account or a complete description of the building(s). The format of the listed building record has changed over time. Earlier records may be brief and some information will not have been recorded.

The only legal part of the listing is the address/name of site. Addresses and building names may have changed since the date of listing and if a number or name is missing from a listing address it may still be listed. Listing covers both the exterior and the interior and any object or structure fixed to the building. Listing can also cover structures not physically attached but which are part of the curtilage of the building, such as boundary walls, gates, gatepiers, ancillary buildings etc. The planning authority is responsible for advising on what is covered by the listing including the curtilage of a listed building. Since 1 October 2015 we have been able to exclude items from a listing. If part of a building is not listed, it will say that it is excluded in the statutory address and in the statement of special interest in the listed building record. The statement will use the word 'excluding' and quote the relevant section of the Historic Environment Scotland Act 2014. Some earlier listed building records may use the word 'excluding', but if the Act is not quoted, the record has not been revised to reflect current legislation.

If you want to alter, extend or demolish a listed building you need to contact your planning authority to see if you need listed building consent. The planning authority advises on the need for listed building consent and they also decide what a listing covers. The planning authority is the main point of contact for all applications for listed building consent.
