A Parliamentary initiative (10.503) launched by National Councillor Adèle Thorens Goumaz (Greens) calls for rainwater to be used more extensively for purposes that do not require drinking water quality. The initiator is hoping to reduce the consumption of drinking water as a result. In addition, the initiative is seeking to increase the amount of rainwater that percolates into the soil. Eawag research projects show that the collection and storage of rainwater is costly, as is any purification required. On the other hand, percolation of rainwater into the soil can help alleviate incidents of flooding.
Case study - Water quality monitoring and weather data at Pampulha Lake-Brasil
In 2010, OTT Hydromet`s partner in Brasil, Hexis began working with CETEC. This resulted in the installation of a buoy, equipped with an automatic profiling system, in early 2013. The project’s objective is the continuous monitoring of the lake’s water quality, with focus on improving this by the 2014 World Cup Games. Adcon, Lufft and OTT technologies (Hydrolab DS5X multi-parameter probe and OTT DuoSens datalogger) are used in conjunction with one another to record the water quality data. Background...
Case study - Water quality in the Mississippi Basin
A resilient method for monitoring water quality and nitrate levels in the harsh aquatic environment of the Mississippi River, in section 16, was required by the University of Iowa -IIHR. The monitoring of continually accurate water quality data was important for analysis, in conjunction with the diurnal mussel study of the University of Iowa.Monitoring water over extended periods of time in this section of the Mississippi can be difficult due to build-up of aquatic sediments and zebra mussels on instruments. Due...
Case study - Remote water quality monitoring in South Africa
Situated in the Mpumalanga province of South Africa, the Xstrata Coal South Africa (XCSA) runs several open cut and underground mining operations producing thermal coal.To ensure their mining operations do not affect the surrounding natural water bodies, the company employs Hydrolab and OTT water quality monitoring equipment with remote data transmission options: the OTT ecoLog 800 water level and conductivity sensor, netDL data logger, and Hydrolab DS5X multiparameter sonde.Installation of this monitoring...
Water Quality & Treatment Centers
A look at the quality of water and the importance of inspecting the integrity of water treatment centers. Water…clear…cold…refreshing. It’s often your “go-to” beverage for quenching thirst after a vigorous activity. We are very fortunate that often within arm’s reach, rests a glass of water. Without hesitation or worry, you can pick it up, calmly place the brim against your lips and, devoid of concern regarding its quality, begin to ingest the water. Why would you...
ITOXcontrol safeguards intake Romanian drinking water Case Study
The Romanian water supply company Apavital has installed a monitoring station to safeguard the intake of water from the river Prut. The monitoring station is part of an integrated monitoring that signals sudden changes in the water quality of the rivers, enabling Apavital to take appropriate measures, in the worst case a stop of the intake. The iTOXcontrol is developed by the Dutch company microLAN that has installed almost 100 stations worldwide, safeguarding the water supply in cities such as Amsterdam, Washingto...
