Der Anschluss privater Schmutzwasserleitungen an Regenwasserkanäle und die Verknüpfung der Schmutzwasserkanalisation mit der Regenwasserkanalisation führen zu nennenswerten Stoffeinträgen in die Gewässer. Belastbare Zahlen zu den Größenordnungen von Fehleinleitungen und der daraus resultierenden Ge-wässerbelastung fehlen bislang. Im Rahmen des Forschungsvorhabens DETEK-T der FH Münster und der Dr. Pecher AG wurden Detektionsmöglichkeiten unter-sucht und Strategien zur Beseitigung der Fehlanschlüsse erarbeitet. Aus den bisherigen Ergebnissen wird der Frachteintrag für den Parameter CSB in NRW abgeschätzt.
Biogaserzeugung und -nutzung

For the increasingly important storage of renewably generated electricity, this review explains the construction of a surface and underground pumped storage
power plant. The problems for the construction of an underground pumped storage power plant are further listed. These are geological, environmental and
economic problems as well as a low acceptance by the population. The geological problems are concerns about leaching of minerals and heavy metals as well as the statics of the cavities. Mining companies in Germany are obligated to renaturalize the landscape areas again, which could be realised by a lake. Furthermore, care must be taken to ensure that the mine water does not come into contact with the groundwater. According to a survey by RISP on the subsequent use of the mine areas for an underground pumped
storage power plant, the acceptance of the population is over 70 percent. The economic consideration concludes that the arbitrage profit for a difference between off-peak and peak of 10 €/MWh is about 2.7 M€/a and for 100 €/MWh about 27.3 M€/a. With investment costs of about 630 M€, despite the assumption of 100 €/MWh, more than 20 years are needed for an underground pumped storage power plant to be amortized. The acceptance could be increased by creating a lake as a recreation area as well as being used as an upper storage reservoir. Thus, the cost of renaturation decrease when combined with the creation of the storage basin. The problem of ground conditions can be solved by creating new cavities by means of tunnel boring at an inclination. For static safety as well as against leaching of minerals and heavy metals, the cavity walls can be sealed with reinforced concrete. The technology of underground pumped storage power plants can be used for better utilisation of renewable energies. This is especially in flat and densely populated regions a possibility to store energy, because the main part of the power plant is underground.
The preservation of water bodies continuity is fundamental
for aquatic communities, particularly for fish
populations. Various structures impede watercourse
continuity, impacting fish migration and habitat distribution.
Conventional fish passages often fall short
in diverse scenarios, prompting the development of
specialized solutions. This article proposes a criteria
catalog for these special fish passage solutions based
on DWA leaflet DWA-A 509. It discusses the need
for these solutions, presents a selection of specialized
options, and outlines criteria from DWA-M 509, construction
guidelines, and economic perspectives. It
scrutinizes criteria ranging from target fish species to
cost considerations. Three examples, including the
Runserau fish lift, the bristle ramp fish lock, and the
Fishcon sluice, illustrate these specialized solutions,
their functionalities, advantages, and drawbacks. Additionally,
the article compiles criteria from industry
standards and guidelines into a comprehensive evaluation
catalog. The criteria, when applied, assist in the
selection of suitable fish passage solutions based on
specific site conditions and fish species requirements.
This holistic approach aims to optimize fishway selection,
fostering the ecological sustainability of watercourses.
However, this catalog remains dynamic
and open to expansion with evolving research and
practical application, urging further exploration and
validation of these criteria through diverse case studies
and technological advancements in the field.

The use of wind power is rapidly expanding worldwide. It is important to examine the impact of wind turbines on the environment to see if they provide a net benefit and to identify potential for improving. Therefore life cycle assessments (LCA) of different wind turbine types are compared in this short review. The results are then shown side by side in tables for comparison. Overall the LCAs show that wind turbines compensate the required energy and emitted pollutants after approx. 6-16 months. The energy payback period (EPP) for 2 MW onshore wind turbines remained roughly the same since 2009 with approximately 7 months. Onshore wind turbines have a higher impact due to emissions but a shorter EPP than offshore wind turbines. The estimated service life of 20 years should be maximized to ensure a high energy yield ratio. The biggest impact on the environment results from the processes to provide the building material e.g. steel and cement. That impact could be reduced by 20 % if recycled steel would be used. It is shown that wind power is one of the cleanest energy sources. But further investigations in material processing and recycling are important to improve the eco-balance of wind turbines.

Intensive Niederschläge (Starkregen) haben im Sommer 2021 zu Hochwasserereignissen geführt, bei denen nicht nur Sachschäden entstanden sind, sondern sogar viele Menschen gestorben sind. In den Sommermonaten der vergangenen Jahre war es lange trocken und sehr heiß. Zu viel oder zu wenig Regen – beides kann lebensbedrohlich sein. Die Auswirkungen des Klimawandels waren Thema des Vortrags.
In vielen Ländern der Erde leiden die Menschen unter Wassermangel und Dürre. Für Menschen in Deutschland sind solche Extremsituationen ungewohnt. Überflutungen sind eher selten und Trinkwasser ist genug vorhanden. Aber was muss dafür getan werden, damit die Menschen mit Wasser versorgt und vor Überflutungen geschützt werden?
Warum regnet es so viel?
