Technical Tours


Tour #1 - Pilsner Urquell Brewery

One may ask a basic question - how is the production of famous Pilsner Urquell related to urban drainage? This relationship is surprisingly positive as you will hear from the Chief Technologist of the Pilsen municipal WWTP, which is thanks to the brewery wastewater, one of few plants with a positive energy balance. During the Pilsner Urquell Brewery Tour you will also learn how water is transformed into the most famous Czech beer. You will see a model of the brewery from the 19th century, the brew house from the 1930s, and the historical cellars, where Pilsner Urquell beer is still produced today using the same traditional method as during the era of the first brew master. Of course the unique method of brewing Pilsner Urquell beer, which is identical to the method introduced in 1842 by Josef Groll, will be explained. You will also have the opportunity to visit the new bottling facility, which can handle 120,000 bottles per hour, and the “heart of the brewery”, a modern brewing facility from 2004. Finally, in the Pilsner brewery you will have a unique opportunity to test “source controls” and compare them to the traditional “end-of-pipe” approach.

Be prepared for cold environment (8 degree Celsius) when visiting old storage cellars. Bring with you a suitable clothing.

Tour #2 - Prague's Flood Protection Measures

In 2002, Prague experienced severe flooding with total damage of 1 billion EUR. This event was recognized as one of the most expensive weather-related disasters in the history of the city, with heavy damages of the infrastructure, housing and environment. Therefore, a modern and complex flood protection system was implemented by the Prague municipality.

Updated detailed description of the tour:
Thanks to the City of Prague and Povodi Vltavy (Vltava catchment management company) we will have a great opportunity to watch year-to-year live operational test of largest flood pumping station in the region of city of Prague at Rokytka creek during our Flood tour (First figure: The facility in operation during flooding in 2013). Therefore we had to make small changes in the tour programme. The tour takes us to Liben district where Rokytka creek enters Vltava River. The facility protects Liben district against backflow and pumps water from urbanized creek Rokytka to Vltava River during river flooding. Maximum design flow rate is Qmax = 20 m3/s and maximal differential head is Hmax = 9.4 m. At this location we also see live demonstration of installation of flood protection walls which are applied all along the river in the city of Prague. After the demonstration you will see the oral presentation about the whole concept of Prague’s flood protection measures.

Tour #3 - Prague Central Wastewater Treatment Plant

Updated detailed description of the tour:
The Prague Central Wastewater Treatment Plant (PCWWTP) is a principal wastewater treatment facility of the Czech capital, Prague. In time of its construction (1966) it was one of the largest and most modern wastewater treatment plants in Europe. Over the years, PCWWTP has been enlarged and modernised several times (1980, 1995, 2011). To meet the current environmental standards given by the EU directive, a “New Water Line” is being built as a supplement of the existing PCWWTP. Therefore, during this tour you will have a great opportunity to see, and learn about, one of the biggest construction sites of municipal WWTPs in Europe. During this visit, one can also learn the design and technology details of this new facility. In September 2017 the project will be in the final phase and we will have great opportunity to visit construction site. During the tour, you will also see the whole complex of wastewater treatment technologies of the existing mechanical-chemical-biological WWTP, including a highly effective sludge treatment enabling almost 90% energy self-sufficiency.

We ask to bring your boots for construction site visit. Be prepare for dirty environment.

Tour #4 - Old Prague's Wastewater Treatment Plant

Prague is one the European cities where the excellent work of father and son Lindleys, the renowned British engineers, left for us an amazing historical wastewater infrastructure. The old wastewater treatment plant in Prague was built between 1901 and 1906 based on the design of William Heerlein Lindley, the son. Most of Prague´s wastewaters were treated here until 1967. Today the building is a part of the European Route of Industrial Heritage, serving as an anchor point. During the tour you will see the original interior of one of the first wastewater treatment plants in Europe with many pieces of the original machinery. The tour will also include a walk through an original main sewer, no longer in use. Copies of the original design drawings and historical photographs from the construction of the plant are on display and you can watch a short documentary film about the plant from 1943.

Be prepared for cold environment. Bring with you a suitable clothing.

Tour #5 - Restoration of Prague's Urban Creeks and Polders

In the city of Prague we can find about 100 creeks with a total length of 357 kilometers. In many of them the water quality, aquatic habitat, public access and stream health are significantly degraded due to channelization and burial serving flood control, stormwater discharges and combined sewer overflows, highway runoff, and illicit litter and garbage disposal.

Updated detailed description of the tour:
Since 2005, the City of Prague is running a restoration project “Creeks for Life”, with focus on re-naturalization of urbanized creeks (for details see and download pdf in English "Projects Completed from 2005 to 2015"). The guided field trip will introduce you to the project itself and several interesting sites with completed or on-going restoration. In particular we will visit Rokytka stream and locations  "Under Smetanka" and sections upstream and downstream from "Hořejší pond" (for details see and download pdf in English "Revitalization of Rokytka Stream"). Tour will be quided by Richard Benes from Lesy hl.m. Prahy (operating company) and biologist Dana Kominkova for Czech University of Life Sciences.

The tour is approximately 6 km long, so be prepared and suitably dressed.

Tour #6 - The Spirit of Old Town Sewers

A recent urban drainage concept of the inner city of Prague is based on the original work of William Heerlein Lindley, the renowned British engineer, who designed the combined sewer network of Prague more than 100 years ago. Why this British engineer was invited to Prague at the end of the 19th century and won this prestigious job? The Prague council received two competitive proposals for a new urban drainage system from groups of German and Czech engineers. To select the winner, the council had hired W.H. Lindley, who reported that both proposals were poor and surprisingly, he came up with his own design and won the competition.

Updated detailed description of the tour:
During the tour of the sewer system under the Old Town you can admire Lindley’s genial engineering skills. The system has been operating more than 100 years. In the bus you will hear short historical overview  about the work of W.H. Lindley in Prague. In the city we will than visit three locations under the supervision of technicians from PVK a.s. (Prague Sewage Company, Veolia CZ). We will start at Old town square in juntion chamber on collector "A" just beneath the famous Astronomical clocks. Than we will visit junction chamber downstream from inverted syphon under Vltava river at the begining of tunnel under Letna hill which is approachin WWTP. Beautiful structure. We will finish in Stromovka park at the end of this tunnel with one the most luxury entrance to sewer network you have ever seen. Why? The entrance was designed for opening inspection of VIPs, namely Franz Josef I, Emperor of Austria.

Be prepared for dirty environment and suitably dressed. We will provide you helmets, latex gloves and medical veil. Overalls not needed. However, we cannot provide you protection in form of Wesley Snipes in Blade II movie who spent hours and hours in Prague sewer network figthing the vamps.

Technical Tour 6 - Old Town Sewers Introduction

Tour #7 - Water Supply and Architecture

Not far from the Prague Congress Centre (PCC), the visitors of Prague can find on the right bank of the Vltava River one of the architectural dominant of the southern part of Prague. It is not a palace, but a drinking water treatment plant built in the monumental neoclassicism style by Czech architect Antonín Engel (1897 - 1958) in the mid-twenties of the 20th century. Antonin Engel was also professor at the Czech Technical University (CTU) and designed the first part of the more recently completed CTU campus in Prague’s district of Dejvice.

For decades, Podoli treatment plant was a main source of drinking water for the City of Prague, withdrawing water from the Vltava River. Today the plant serves only as an emergency source of water supply, which is in operation once a year.

However, in this tour the main point of interest is the architecture and history. Therefore, the tour will be guided by prof. arch. Arnost Navratil from CTU, who worked on the team of architects Navratil - Pav – Frydecky on restoration of the treatment plant in the 1990s. Thanks to their work, we can see ‘genius loci’ of that place again.

History of water supply of the City of Prague can be studied in the museum located in the Podoli treatment plant and the history of Czech governance will be presented during the walking tour from PCC to the treatment plant, passing through a nearby castle Vysehrad (45 min walk). This place served as the first headquarters of Czech princes in the Prague region founded in about the 7th century. The visitors of the Vysehrad castle can also visit the Slavin cemetery, which is a resting place of many greats of the Czech culture, including Bedrich Smetana, Antonín Dvorak, Alfons Mucha, Karel Capek and many others.

At the beginning we will create two groups. First group goes directly by bus to Water treatment plant, the second one will start with Vysehrad guided tour (walk around 40-45 minutes) with the end in Podoli treatment plant. On the way back we will change the roles.
