document describes the pilot project for implementing a data logger-based telemetry system to This inflows and outflows of the Integrated Water Management Districts (IWMDs). The main monitor of the implemented pilot project was to strengthen the capabilities of the IWMDs’ purpose staff to monitor and analyze water. distribution The system was implemented at eleven operations structures and pumping stations. At irrigation structures, the system provided real or near irrigation time information on water levels and flows. At the pumping stations, in addition to monitoring real level data, the system monitored changes in pump status, operating hours, and flow. The pilot water included monitoring water quality parameters (pH, conductivity, and dissolved oxygen) at project sites. Moreover, a local warning system was included in the pilot project at one pumping some site, in addition to a short message service- (SMS) based warning system. station data will help in calculating water flow volumes at major inflow and outflow points, in order to The water quotas for each district and achieve enhanced water management. Having these data monitor in real time will be of great benefit in achieving integrated water management. The system available data loggers equipped with GSM modems at irrigation structures and pumping stations. The data uses Task 3. Data Logger Based Telemetry Monitoring System 1.

order to minimize the capital cost, the Ministry of Water Resources and Irrigation’s (MWRI) In telemetry network was utilized to serve this pilot project. The MWRI already has a existing system that monitors water level data and uses VHF as the communication media. The telemetry is complicated in its structure. Moreover, the performance of this old system is not system partly due to the long path of data, VHF interference, and faulty equipment at the end of satisfactory, useful life. its pilot system uses the existing infrastructure of the telemetry network. The existing water levels, The conduits, batteries, solar panels, solar regulators, and civil construction were used following cables, maintenance. A data logger with sufficient input and output was connected to water level minor The solar panel and battery were used to provide continuous power to the low power sensors. data logger. The new equipment, data logger, and GSM modem were installed inside consumption same box from the existing telemetry system. the existing water level sensors were connected to the data logger. The data logger continuously The measured data from the sensors. This data could be provided to any remote location in a real read sense. The data logger also stored measured data according to predefined intervals with a time of 1 minute. The stored data could be downloaded remotely at any time by the GSM resolution The time resolution used in this project was an hour, which meant that data loggers stored network. readings from all sensors and saved the data to a file. hourly pilot project achieved another important planned objective related to evaluating MWRI plans to The the existing telemetry system. The Ministry, with support from the United States Agency renovate International Development (USAID), invested a lot of money in the telemetry network in early for USAID supplied US$56 million to implement the network throughout the country’s irrigation 1990s. Recently the performance of the telemetry system became unsatisfactory and its support networks. water management was diminishing. The Ministry has been studying renovating approaches to get to system in service again to make use of the earlier investment. The pilot showed that the existing the can be renovated at a very small capital investment. network equipment was chosen to achieve reliable operation and accuracy, be low in power The and be compatible with the latest technologies in the field of communication and consumption, systems. System features include accuracy, simplicity, reliability, and flexibility. Accuracy electronic achieved as a result of precise data logger acquisition capability. The compact size of the was and its ease of use make the system simple. Reliability is achieved with the outstanding equipment and low power consumption of the data logger. The flexibility of the system operation performance different ways to collect data. The data stored hourly could be collected using three different allows methods: Direct connection, using a Personal Digital Assistant (PDA) or laptop computer • Using a memory module • Remotely, using a GSM modem. • could be monitored and collected from any IWMD or irrigation directorate office using a GSM Data network. During the past years, the system gave excellent performance and communication accurate measures of water levels and flows. The stored and collected data is useful not provided for daily system operation but also for system planning. Operation policies for irrigation only are being revised based on these data. The water level monitoring network ensures that structures needs are met. The data collected at pumping stations helped to solve conflicts between the water Task 3.
