Other water scientists ask me how we know whether the water resources in Uganda are adequate to supply all the new water wells we and others are installing. With water shortages in places like California constantly in the news in 2015, this is a question we are addressing with actual measurements of the water levels in wells we’ve installed in Uganda. Thanks to the very generous donation of electronic transducers from two manufacturers, we are now collecting water level data every 15 minutes from three wells. A fourth transducer will be installed in the solar-powered well on the FEM Farm by a well service company the next time they are in that region.
In-Situ Inc, based in Fort Collins, Colorado, donated two of their Rugged TROLL® 100 Data Loggers and two Rugged BaroTROLL Data Loggers to this project. The BaroTROLLs record atmospheric pressure, which is used to adjust the transducer data so it reflects only water level changes due to groundwater fluctuations. One of the In-Situ Rugged TROLL 100 transducers was installed in the Moroto West well in northern Uganda (pictured). This is a very remote area of the country which is still in the process of recovering from the devastation of the LRA war.
The water level and water temperature data from this transducer will give us information on the groundwater response to the annual wet and dry seasons, and will also reveal the times and amount of daily use of the well by the community. By recording a water level every 15 minutes, the data will indicate the timing and duration of water level drawdown due to pumping. The second In-Situ Rugged TROLL 100 transducer will be installed in the solar-powered well on the FEM Farm by a well service company on their next visit to that area. Two of our Ugandan colleagues on the Farm, Richard Angoma and Bosco Tolit, have been trained in the use of the software to retrieve and process the In-Situ transducer data.
HydroSolutions thanks In-Situ for this valuable donation.
