1 Measuring And Logging The Discharge Behaviour Of Stormwater Overflow Tanks EVENT LOG

2 EVENT LOG MEASURING ON stormwater tanks Advanced stormwater treatment thanks to measuring and logging with NIVUS The importance of measurements and recordings on stormwater treatment facilities is constantly growing. It is not only authorities who demand proofs and protocols on impoundage events and overflow volumes; such data moreover represent an important planning basis for the expansion of previous settlement areas. In Germany e.g. there are currently around stormwater overflow tanks and storage sewers in use (status as of ). According to the Water Act, operators are responsible for the correct operation of such facilities. To prevent water pollution and to ensure environmental protection, these plants (such as municipal wastewater treatment plants, sewerage systems, stormwater treatment plants and industrial wastewater treatment plants) need to be checked regularly. Moreover operators are obliged to create protocols on several operational data. 2

3 Measurement - data recording - data transmission - calculation and logging - the complete system from one hand Using high-quality measurement systems alone is not enough when it comes to ensuring plausible and accurate results. Having gained 25 years of experience with planning and configuring the best possible measurements and transmission systems for stormwater treatment plants, our engineers and technicians are capable of providing professional and reliable solutions.

4 EVENT LOG NIVUS - your expert for measurement solutions on stormwater overflow tanks Modern data logging does not need to be expensive... As a worldwide leading developer, manufacturer and supplier of measurement systems for the water industry, NIVUS offers a range of products which allow costefficient, economic and reliable recording and logging of measurement data even without being dependent on public electricity networks. The market reveals large price differences regarding overall costs particularly if facilities need retrofitting or smaller tanks are not yet equipped with appropriate logging systems Data transmission and server utilization more cost-effective than DSL connection. Given a 5-minute recording interval, two transmission events per day and two error messages via SMS (high priority) per month the total costs are less than 10 Euro/month.
