At the end of March 2009 The Warsaw Surveying Company WPG S.A. took place an important exhibition about Warsaw „Hoppe, Lindley, WPG, Warsaw Cartography 1641-2009”. The exhibition was organized by The Warsaw Surveying Company WPG in cooperation with the State Archive of City of Warsaw (APW).
Author of the exhibtion was Paweł Weszpiński, member of Board of our Societas
Lindleiana, which administers and takes care of the so called Lindley plans in
the archive. The exhibition was
dedicated to the 150 anniversary of birth of Josepha Lindley, the younest of
three Lindley brothers.
The exhibition reminded Young generation that the waterworks and sewage systems as well as modern surveying of the city is to thank family of English civil engineers, father William Lindley (1808-1900), and sons Sir William Heerlein Lindley (1853-1917), Robert Searls (1854 – 1925) and Joseph (1859-1906).

The Warsaw City Archive Has a largest

see the colour plan of 1897 r., renovated in 2009 r. thanks to financial
support of the Ministry of Culture and national Heritage:
Of the three water suppliers in Warsaw, the Central Department of Water (Zakład Wodociągu Centralnego, or ZWC) is the oldest and largest. Built between 1883 and 1886, it has supplied water to the inhabitants of Warsaw since that time and continues to meet 50% of the capital’s water needs. Its technology today remains largely faithful to the original, and was first designed by William Lindley and his son William Lindley Heerleina; this design was enriched and improved in 1933 by the Department of Rapid Water Filters. The second wave of technology was launched in 1972, in which specially fired, moisture-resistant bricks were used.
The outbreak of WWII brutally interrupted the successful distribution of water
in the city, with the bombing of September 1939 and the Warsaw Uprising in 1944
causing massive damage, as the main buildings and their networks suffered a
direct attack. On September 22, 1944 Warsaw's water supply was completely cut
off, and was not restored again until May 29, 1945. The damage was worsened by
the fact that much of the water filtering machinery was stolen by the
retreating Germans, and so both reconstruction and replacement of equipment
took several years.
Currently, the ZWC uses an ultra-modern, fully equipped laboratory to test the
water at all stages of its treatment and supply. In addition to water quality
control continuously being performed by the laboratory, selected parameters are
constantly monitored by an on-line measuring device.
Hidden beauty of the clean water tanks
The filtering station has open days in July and August, and invites visitors to see the historic technology that has functioned for over 120 years. Visits must be pre-arranged, and are by invitation only; the booking office begins accepting requests in the last week of June, at which time ZWC security issues as many invitations as possible, based on one's preferred date, time and number of guests.
