A bit disappointed that there is no reference to the history of this technology.Where was it first developed?I believe that some of the first slow sand filters in the world were put into service by a town on the River Aire (Yorkshire, England) in the 1830's but can find no reference? #### —Preceding unsigned comment added by 86.157.106.74 (talk) 19:22, 6 June 2010 (UTC)Reply
