Bielefeld University (Germany) partners visit at Water Research laboratory

At the beginning of March, partners from Bielefield Univeristy, Faculty of Physics (Germany) came to Riga, to Water Research Laboratory, to meet Prof.Talis Juhna and Asoc.Prof.Jānis Rubulis. Thus partners from Germany (physics of supermolecular systems and surfaces) introduced more closely with plans about developing a new material for forwarding osmosis applications. They were shown laboratory and introduced with us. Also partners discuss about possible cooperation in the future, in the field of carbon nanomembranes.  

New Doctor in Water Research Laboratory

We are proud to announce that Sandis Dejus, a researcher at our Water Research Laboratory, successfully defended his doctoral thesis “Online Monitoring of Drinking Water Quality”.  Within the framework of the doctoral thesis, analysis of drinking water quality monitoring requirements and systems was performed and a new solution for drinking water quality online monitoring was developed.

And on 25th of February at the meeting of the Senate of the Riga Technical University (RTU) our new Sandis Dejus received his diploma!


The International Education fair “Skola 2019”

The 25th International Education fair “Skola” (From 1 to 3 March, Ķīpsala ) – the most important event for thousands of young people in Latvia to offer the broadest and quality coverage of study opportunities in Latvia and abroad. Also, Senior researcher Jānis Rubulis and Sandis Dejus from Water Research Laboratory, one from the more than 140 participants, took a part in this fair by introducing with the workshop “Drinking water miracle” to help visitors raise interest to water science and, probably, to become one of us!

Special issue “Drinking Water Treatment and Removal of Natural Organic Matter”

Prof. Dr. Talis Juhna took a part in the Special issue “Drinking Water Treatment and Removal of Natural Organic Matter”

iWatermap experts participation in Cleantech Latvia General Meeting

On January 31, RTU iWatermap ( experts Jānis Rubulis and Dāvids Štēbelis where involved in Cleantech Latvia General Meeting of Members. David presented some of the most important observations from the company interviews conducted in the iWatermap project and presented publicly available funding for collaboration with universities in the near future.

RTU experts together with RTU Design Factory ( Project Manager Liene Briede did presentations about iWatermap project concept, financial opportunities for Industry – Academia cooperation.

After the main event participants look around premises of RTU Design Factory and were introduced with technical opportunities and prototypes build for water industry.

Visit to Cēsu alus

At the end of the year 2018, WRL staff Janis Rubulis and Sandis Dejus visited JSC Cēsu alus. The purpose of the visit was to evaluate and analyze the risks of drinking water abstraction and water supply system at JSC Cēsu alus. JSC Cēsu alus was chosen as one of the pilot sites for testing the concept of Water Safety Plans in Latvia.


NOAH kick-off meeting in Tallin, 28-29.01.2019.

January 28-29, Tallinn University of Technology, Faculty of Construction and Architecture hosted a NOAH project kick-off meeting.

All partners gave a brief presentation of their experiences, challenges, and competencies.

Both “Jūrmala Water” Ltd and Liepaja City Municipality “Communal Authority”  also presented potential pilot sites where the project will be carried out by testing of key ideas – modeling of precipitation loads in prepared and combined sewerage systems. The Ogre Municipality, on the other hand, presented the section of the Ogre River, which will simulate the flood hazards of populated areas caused by precipitation as well as the winter period.

In these pilot sites, water quality testing is planned for two years with the aim of determining the pollution load on the Baltic Sea, extreme weather conditions, as well as the impact on the environment from decentralized wastewater facilities.

Interesting experiences in the context of the use of online devices in infrastructure and modeling of different scenarios during the flood were presented by Gdansk University of Technology and Slupsk Water Supply. In turn, the municipality of Ogre, in the context of the floods caused by the river, will learn from the experience of the city of Pori.

At the meeting, RTU was represented by a senior researcher of Water Research Laboratory Jānis Rubulis and Associate Professor of Geodesy Department Maris Kalinka.

Presentation at LifeSciences Baltics 2018

From 25th to 27th September WRL senior researcher Linda Mezule participated in LifeSciences Baltics 2018 event ( that is the only international forum in the Baltics for world-class biotechnology, pharmaceutical and medical devices experts from all around the world. Linda presented a poster that describes all WRL competences in the field of fluorescent imaging and new microbial identification tools.

NOAH – a new INTERREG Project on reducing urban stormwater

On 20th of September the results of the 3rd call for INTERREG Baltic Sea region ( Projects were announced. One of the Projects to be funded will be NOAH lead by Department of Civil Engineering and Architecture from Tallinn University of Technology in Estonia (

The project will tackle the challenge of reducing urban stormwater runoff and the spillages of untreated wastewater into the receiving waters caused by extreme weather such as heavy rains and floods. NOAH develops a new layer for extreme weather events to be used in computer based modelling of drainage. By combining this modelling with traditional city planning techniques municipal planning shifts from fragmented individual site based planning to a holistic approach covering the entire urban catchment.

In the NOAH project RTU will be represented by Water Research Laboratory and Spatial and Regional Development Research laboratory both from Faculty of Civil Engineering. RTU team will be complemented by Department of Modelling and Simulation in the Faculty of Computer Science and Information Technology.

Three municipal enterprises from Latvia will be involved in the NOAH Project: Jurmalas udens Ltd (, Liepaja municipal authority “Komunālā pārvalde” ( and Ogre municipality (


NOAH Project will begin in 01.01.2019.

iWatermap project Partner meeting

From 24th to 28th of September the staff members of Water Research Laboratory Jānis Rubulis, Dāvids Štēbelis, Tālis Juhna and Jānis Zviedris (representing as well company Inducont and CleanTech Latvia) visited Leeuwarden (Netherlands). In these days were official kick-off meeting of the iWatermap project (

The meeting was dedicated for exchange of information regarding the critical mass in the water sector in all partner countries/regions.

The meeting was attended by several Latvian stakeholders. From RTU Engineering High School ( joined chemistry teacher Laura Fjodorova, from CleanTech Latvia (  Evija Pudāne and Andrey Belogorsky (also representing company Karme Filtrs

Within the framework of the iWatermap project, cooperation between the Latvian water industry stakeholders will be strengthened taking into account experience of the iWatermap consortium leader Wetsus (

The iWatermap project has activated the collaboration of the Water Research Laboratory with CleanTechLatvia, which focuses on the development of research topics defined by the original equipment manufacturers. Also, better targeted cooperation with the RTU Engineering High School is expected for high school students to test their talent in research related to the water sector.

Within the framework of the project, the issue of lifelong learning in the water sector will be activated, which is critical for municipal companies in the context of the aging of employees, as shown by data collected by the State Employment Agency (

The iWatermap meeting was held at the same time as the European Water Tech Week (EWTW 2018), which brought together hundreds of stakeholders and during event sixth global water technology innovation hubs signed agreement of cooperation:
