(Microsoft Access database) Lists 145 items which remain underground or lie in private hands. The list is far from complete, but it gives an flavour of the type of existing relics relating to HDUM Ltd.

Sealing Alyn TEXT (Part 1):  

(PDF file) An unpublished report by HDUM dated 1938 entitled "An Attempt at Sealing Natural Water Holes or 'Swallows' in the River Alyn": Describes extensive work carried out by HDUM to reduce the water entering the Milwr Tunnel via natural fissures. Re-typed, but the text & layout formats reflect the original. The original report includes many pages of supporting (but fairly boring) information which are not included in the file below, although the main area plans showing individual swallows are attached as a seperate file below as "Sealing Alyn PLANS".  The original document is held at Flintshire Record Office, Hawarden.


Sealing Alyn PLANS (Part 2):  

(PDF file) Three specific areas of the Alyn Gorge showing the work carried out in the 1930s, but now (Oct 2009) with a fourth plan of the entire Alyn Gorge showing all the gauging weirs, diversions and areas of worst leakage. All four have been re-drawn from the originals for clarity.
