A number of researchers from several departments of WUT (including electronics, chemistry, physics and environmental engineering), created a task force group called the Photonics Engineering Research Group. Three years ago, the Group engaged its activity in the Photonics Engineering Priority Research Program of WUT. One of the first tasks was to research, design and do an efficient model of a photonics based, telemetric network for environmental applications. This task took three years to complete. Here we present the results of eventual environmental tests of the Network Measuring System (NMS). NMS bases on and uses the resources of the global network. On the software platform, it is integrated with the Intranet and Internet. NMS uses a log of photonic equipment including: various photonic sensors, optoelectronic receivers, transmitters and signal conditioners and regenerators, measurement standards converters with photonic ports, fiber optic cabling of different type, etc. The photonic sensors applied in the NMS can measure temperature, pH, pK, pNa, pCa, opacity and turbidity, flow, pressure and several other values. Two major directions of practical real-life applications were chosen for the NMS. These applications were municipal, water distribution and, sewage purification, management system and meteorological weather station. Here we present the first application. The description presented here is from the point of view of environmental tests, as it is the third article in series. The first two parts, included in this volume, describe the NMS in details.
