Analytical Task Group
'The Analytical Group has a principle aim to promote and generate good practise in the selection, installation and operation or analytical monitoring equipment in the water environment, particularly focused on the water, wastewater and industrial effluent sectors.
Analytical monitoring equipment includes all instruments and analysers that are used to monitor 'Qualitative' parameters such as the MCERTS parameters (Ammonia, COD, Conductivity, Dissolved Oxygen, Free Cyanide, Nitrates, pH, TOC, Total Chlorine, Total Oxidised Nitrogen, Total Phosphorus, Turbidity). The group are also keen to look at process control parameters such as Mixed Liquo Suspended Solids and are open to requests for guidance on any measurement need.
These measurements are key to the successful operation of treatment systems providing vital information for both process control and for pollution prevention. The Analytical Task group is currently looking at the use of Turbidity as a discharge consent parameter in place of the more traditional Suspended Solids, we are also generating guidance notes looking the definition of terms such as Ortho-Phosphate and Total Phosphorus. Questions are welcome about any analytical issue.'
Flow Monitoring Task Group
'The Flow Group has the principle aim to promote and encourage good practise in the selection, installation and operation of flow measuring instrumentation in the water environment, particularly focused on the water, wastewater and industrial effluent sectors.
Flow measurement includes both closed pipe using typically electromagnetic or ultrasonic flow meters plus open channel flow incorporating level measurement.
Accurate flow measurement is essential for both leak detection and demand planning. For discharge measurement the group seeks to clarify the position with regards MCERTS and the requirements put upon the end user by current guidelines issued by the Environment Agency.'
Technical Task Group
We are organised to support and advise members in their dealings with the EA and SIRA regarding MCERTS. The task group reviews current and future legislation and all other technical aspects relating to water monitoring.
Process Instrumentation Task Group
'The Process Group has a principal aim to promote and generate good practise in the selection, installation and operation of Process Instrumentation in the target industries of the WMA, namely the water, wastewater and environmental sectors.
The principle focus technologies of the Process Group are pressure, temperature, data acquisition and level, with the exception of open channel level measurement for flow.
These types of measurements are utilised for many purposes, from aspects of process control to stock control. As such, whilst not headline outputs such as flow or quality parameters, these measurements are important for the smooth, efficient and safe running of many systems and processes. Ultimately they help ensure a discharge that meets all regulatory requirements.
Consequently, careful consideration is required when choosing, designing and installing such devices, as errors in these areas can greatly influence the accuracy and repeatability of the results.
The Process Group decided on two initial areas of focus for guidance notes, namely the installation of differential pressure devices, and the selection of non-contact level measurement devices. A secondary focus is overflow measurement in Combined Sewer Overflows (CSO’s or UID’s).'
