Each of us needs a heart, this source of emotions and feelings, and at the same time the most vital part of our body, pumping blood to make our organism function. For Warsaw, similar role is played by the system of waterworks and sewerage, respectfully called “Warsaw Water Filters.” This vast, green area with underground infrastructure is the constantly beating heart of the city.
In their 130-year-old history, Warsaw Water Filters underwent many changes, they were subjected to innovative ideas and inspired great plans of great people. Owing to their knowledge and determination, the visionaries of their time, Henryk Marconi, Alfons Grotowski, William Lindley and Sokrates Starynkiewicz, created advanced waterworks and sewerage system for the capital. In this way, they shaped the course of future progress of the city. Lindley had pictured the 20th-century Warsaw as a multi-million agglomeration and already provided for its need during the construction of waterworks in the 19th century. Lindley's plans are still being realized by Miejskie Przedsiębiorstwo Wodociągów i Kanalizacji w m.st. Warszawie S.A. (Municipal Enterprise for Waterworks and Sewerage in Warsaw, plc). This enterprise has nine specialized plants, where sewage is treated, and water is tested and purified.
Warsaw Filters' facilities left their glorious imprint on the pages of history of the city and history of industry. An English engineer, William Lindley, accepted the invitation of the acting Mayor of Warsaw, Sokrates Starynkiewicz, and came to modernize the city by constructing a vast network of waterworks and sewers. It was a grand project, for which not only technical plans had to be made; detailed cartographic work was required and the maps which were created then are still admired today as Lindley's Maps.
A special drainage system extracts water from under the bed of Vistula River. Then, water it is pumped by five pipes to the Filter Station, thirty-six meters above the level of the river. Firstly, it goes through the processes of coagulation and sedimentation inside so-called pulsators. After that, water passes through rapid sand filters. The next step is purifying with ozone and filtering with active carbon. This process takes place in a new plant, dedicated to ozone-purification, which is located in the south-western part of the Filters.
In the last stage, water is directed to slow sand filter tanks (the original ones, designed by Lindley), which occupy a vast space. There, water slowly seeps through layers of active carbon and sand in gigantic containers. Finally, it is disinfected with chlorine dioxide, after which it is ready to go to underground tanks for pure water. From there, water is pumped around the entire city, ready to be used. In the 19th century, such complex systems of waterworks, filters and sewerage as the one created in Warsaw were operating in only a few most modern cities in Europe. Warsaw Filters are the only original system of that time that remained until today.
The grandiose of the project, exemplary quality and precision of construction are comparable with contemporary astronautic procedures; the efficient technology of the past has become an artwork of enginery and construction. In 2012, the Filters were given the status of Historic Monument, confirming their symbolic value for Warsaw inhabitants.

In the summer of 2016, the descendant of William Lindley, William V, visited Warsaw Filters and admired the work of his great-great-great grandfather
