From Marleen's last visit, she advised the project to have a Geohydrologist or an expert to survey on the soil conditions for suitable groundwater wells specifically in Bogo Water District and Carcar Water District.
Ton Ebbing, a Geohydrologist from Vitens, visited the PEWUP project and its project partners on September 2018 for the following assignments:
-Conduct site visits to the different areas of all the Water Districts to see and give recommendations where they can drill new sustainable water sources -Assessment and recommendations for operation and maintenance of deep wells at all Water Districts -Capacity improvement of Water District staff
Short-Term Expert Ton was able to visit only three of the project partners among the four on his first visit. He visited Carcar Water District, Toledo City Water District, and Bogo Water District. Together with the key personnel from each of the Water District mentioned, we visited different sites of the Water Districts' areas. The Water Districts requested Ton to visit the areas where they conducted a Geo-resistivity Survey and the areas where they think they can drill new groundwater sources. Deep wells, pumping stations were also visited and discussion on how each of the Water Districts' systems works was also done.
On his first visit, he was able to give specific recommendations on where the Water Districts can drill for groundwater. Part of the capacity building for the Water District staff, Ton conducted a Well Management training to the key personnel of the Water Districts for them to be able to improve the overall water production. With proper well management, the life expectancy of a well will be improved. Well clogging and well aging can be stopped or even reversed resulting in higher yields and lower production costs. It was also recommended to purchase a deepwell camera to investigate the situations of the deepwells of each Water Districts.
Prior to Ton's second visit in March 2019, the purchase of the deepwell camera was already done. When he visited the four Water Districts, the well camera was used to investigate the deepwells. For CWD, TCWD, and BWD's deepwells situations, there were small particles seen in the recorded video using the well camera. STE Ton advised to do airlifting to clean the deepwells. He discussed to the Water Districts' key personnel how to operate the Well Camera and how to do airlifting where they do not have to spend a lot of money. During his visit, he also shared a free Pump sizing software and showed how it works. The pump sizing software helps anyone who wants to have the right pumps for their system before purchasing. In the pump sizing software, it will ask for some information of your wells or reservoirs depends on where you will install it and then it will recommend what's the right kind of pumps for your system. The beauty of the software, it also shows the energy needed to be able to pump the desired capacity of water.
Together with the deepwell camera, the project also purchased some TD-divers that was given to the Water Districts. The TD-Diver is a submersible datalogger for long-term uninterrupted, real-time water level monitoring using a pressure sensor when submerged at a fixed level under the water surface. The pressure sensor measures the equivalent hydrostatic pressure of the water above the sensor diaphragm to calculate the total water depth. The Diver autonomously measures pressure and temperature and records them in its internal memory. The Diver is ideal for ground and surface water level applications.
Ton's visit was very satisfying for the Water Districts and for the project as everyone had a great time working with each other. So many things were learned that can be applied in improving the practices of the Water Companies towards an excellent service for the customers.
