caption_attribution_description: English: Ventilator shaft I believe this is the south west terminal ventilator shaft to the Esholt sewage tunnel running under north east Bradford. The centre co-ordinates of the tunnel portal at Esholt Sewage works and this shaft form a straight line that misses the co-ordinates of the shaft in SE1636 and the shaft in SE1737 by less than one metre. Its location is right next to the (now filled in) canal just off Canal Road.
context_page_description: Esholt is a village between Shipley and Guiseley, in the metropolitan district of the City of Bradford, West Yorkshire, England. It is situated 4 miles east of Shipley, 4 miles south-west of Guiseley, 5 miles north of Bradford, and 12 miles north-west of Leeds.
  The name "Esholt" indicates that the village was first established in a heavily wooded area of ash trees.
context_section_description: As Bradford's population and the textile industry grew in the early 19th century most human waste and industrial effluent drained into Bradford Beck, to the canal basin and on to the River Aire flowing past Esholt.
  In 1862 a sewage system was begun in Bradford but Bradford Beck was still polluted. In 1869 William Stansfield of Esholt Hall obtained an injunction requiring Bradford Corporation to improve the sewage system so as not to pollute the beck.
  Bradford Corporation built a treatment works at Frizinghall to treat sewage before the water was put in the river.
  When Frizinghall works could not cope with the waste the Esholt estate was acquired for more than £239,000 as the site for a new sewage works. A three-mile long tunnel between Frizinghall and Esholt to connect the sites was completed in the 1920s.
  Frizinghall works closed in 1926.
  The tunnel has ventilation shafts in Frizinghall, Wrose
  and Idle.
  In the site's Sludge Disposal Building later known as the Press House, 128 steam filter presses compressed sludge to recover grease (lanolin) which could be used for a variety of applications, and the press residue was sold as fertiliser to meet the cost of operating the plant.
  After Bradford's woollen textile industry declined, the Press House became roofless and derelict.
