In order to overcome the
problem of the ineffectiveness of sewerage overflows throughout
Belgium, some 300 monitoring stations are being installed
using sensors developed by Partech for measuring water flows
and water quality.
At the beginning of this decade it was reported that increases
in the number of watercourses holding "acceptable"
or "not polluted" qualification had not been maintained
in spite of ongoing treatment efforts. In order to gain a
clearer picture of this problem the Flemish Environment Society
(VMM), the equivalent of UK Environment Agency, started a
new monitoring project in 2003 using field measuring installations
on overflows throughout its operating territory.
The solution developed by Swedmeter AB and Partech Instruments
and supplied by C.R.A.nv uses more than 300 solar powered
monitoring stations which employ loggers that can store data
locally and transmit the data by means of wireless communication
to a central data base. The Swedmeter logger and data communication
package is located with the solar power system above ground
level whilst Partech Instruments’ WaterWatch sondes
are underground. In this case the sondes monitor Conductivity
and Suspended Solids. Alternative sondes can add pH, Redox,
Dissolved Oxygen and Level.
“The WaterWatch sonde is a compact fixed site unit
that can contain up to five separate sensors,” says
Angus Fosten, Partech sales and marketing director. “Most
importantly for remote locations, the instrument has been
optimized to require a very low level of power.
Besides giving an indication of the duration of the overflow,
each monitoring station also provides an estimation of the
actual flow and the degree of pollution of the drained water.
Analysis of the collected data will enable VMM to establish
a clear picture of these problems and develop appropriate
solutions to overcome the problems that they face.
For Partech Instruments, the size and scope of the application
is a major confirmation of the capability and reliability
of its WaterWatch technology. With some 300 sites now being
kitted out, Partech has a sizeable installed base offering
considerable potential for demonstrating the performance of
its products. The idea has already been picked up in Spain
where a number of similar packages are currently being trialed.
