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 24.000 stormwater overflow tanks and storage
sewers in use (status as of 01.10.2007). 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.
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.

NIVUS - your expert for measurement solutions on stormwater overflow tanks
Tank in main connectionMeasuring tank impoundage and tank overflow

Devices:
Level measurement: 2 ultrasonic sensors or
pressure measurements
Data/Transmission: data logger/GPRS
Logging: software-independent,
D2W Internet platform
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 cost-
efficient, 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.

NIVUS event logging - reliable and convenient
EVENTLOG
Event-relevant data are transmitted via
GPRS from the outpost to the D2W
Internet portal where they are saved
reliably.
It is here where outposts are managed
and data are evaluated, calculated and
logged. Users have secure access to
their data and logs without the need for
particular PC software. Using an Internet
explorer it is possible to directly print out
or to save the data on PC/Laptop.
Create data logs with just a few clicks
