„Challenges and Solutions of Municipal Water Supply System in Dresden/Germany“

 

 

 

Dr. Christian Korndoerfer, Dresden

 

 

 

According to the principle of subsidiarity in German constitution the supply of the citizen and enterprises with potable water is one of the public services the municipalities have to provide. The transformation of the state operated water supply of socialist time before 1990 to a municipal one was a big challenge for the City of Dresden. Now the water supply is managed in high quality by municipal company DREWAG. The transformation concerned not only the takeover of the pre-existing facilities for water extraction, collection and distribution but the design and realization of a water supply system that can fulfil the ecological and hygienic standards now and in future with an acceptable water price. The system is based on three columns: ground water, river bank filtrate and import of surface water from basins. Due to contamination by former careless industrial use of hazardous substances the city administration has started ambitious remediation program of soil and aquifer. It took more than 2 decades to achieve  good quality of raw water again. In the late eighties the water consumption exceeded natural water regeneration. This gap was closed rapidly, mainly by the water saving effect of metering and prizing water consumption and by reduction of non-revenue water losses. The ongoing climate change more frequently will provoke drought periods and flood events, both affecting water extraction and water quality. The response on this challenges is the establishment of complete redundancy in case of failure of one of the three waterworks, the planning and safeguarding of an additional protection zone for the extraction of bank filtrate and the steady improvement of water cleaning techniques. The increasing deficit in precipitation observed for the last four years is calling for further development of water saving and water storing techniques. The responsible experts of DREWAG and water authority are interested in steady exchange of experiences, knowledge and ideas according to Habitat-3-Agreement to fulfil the sustainable development goals.

Dr. Majid Sartaj is a Professor of the Civil Engineering Department, University of Ottawa. He obtained his Ph.D. in Environmental Engineering from in 2001. After graduation he worked in consulting industry, where he was Project Engineer for the development of the first Engineered Landfill for the Caribbean nation of St. Lucia. He was then became a faculty member of Isfahan University of Technology, Iran, before joining University of Ottawa in 2011.
Dr. Sartaj’s research has been directed towards developing and optimizing sustainable solid waste management (SWM) technologies, with the main focus on Bioreactor Landfilling, Anaerobic Digestion and Biogas/Renewable energy production. Bioremediation of contaminated soils and reduction and removal of contaminants released by different industries and agricultural activities such heavy metals, cyanide and nitrate and modeling their fate and transport in the environment are among his other research topics of interest. He is actively collaborating with industry and many of his research projects are funded by industrial partners.
Dr. Sartaj is the author or co-author of numerous research publications in peer-reviewed journals and conferences, and one book chapter. He has supervised or co-supervised more than 50 graduate students (HQPs). Dr. Sartaj has been an active participant and organizer of several national and international conferences.

The Status of Covid-19 in Urban Areas via Monitoring Municipal Wastewater




Majid Sartaj, PhD, Peng,
Professor, University of Ottawa, Ottawa, Canada



The Severe Acute Respiratory Syndrome-Coronavirus Outbreak 2019 (COVID-19) has caused worldwide concern and has affected all aspects of human life. Many urban regions have struggled to keep up with testing individuals for Covid-19. One potential alternative employed by many communities is to collect and analyze samples from municipal wastewater to assess and track the spread and occurrence of Covid-19, and potentially identify regions where disease incidences is increasing. This could help decision-makers to plan accordingly. Recent research findings on monitoring and surveillance of Covid-19 through sampling and analysis of municipal wastewater are reviewed and presented here.
