Client: Local Government of Aritao, Nueva Vizcaya
Location: Aritao, Nueva Vizcaya
Aritao, Nueva Vizcaya faces an urgent need for reliable groundwater sources to support its growing residential and commercial areas. With limited water availability and minimal geological data, finding a sustainable water source was a top priority. Aritao supports a total population of 42,197 as of 2020. The project would support creating a new municipal drinking water source to support the growing population of Aritao, Nueva, Vizcaya. Source: PhilAtlas
Barangays Poblacion and Banganan are served by ARWASA and BALIBAGO Waterworks. With the Sagana at Ligtas na Tubig para sa lahat (SALINTUBIG) PROJECT of the Department of Interior and Local Government (DILG) in coordination with the Local Government Unit, eleven barangays (Bone South, Bone North, Calitlitan, Comon, Cutar, Darapidap, Kirang, Latar, Nagcuartelan, Tucanon and Yaway) are recipients of said project. And it serves as the major source of potable water in their area of responsibility.
However, seven out of 11 are operational and managed by the registered Barangay Waterworks and Sanitation Association (BAWASA). The other four are not yet operational in nature due to lack of water supply and water system rehabilitation. Aside from the SALINTUBIG project and private waterworks, other sources of water supply for drinking are the 17 water refilling stations, shared tubed/piped deep well and protected spring. There are 7,556 households or 72% of the total household of Aritao with access to potable water. Source: Aritao Ecological Profile.
The geoelectric resistivity method is the most suitable and efficient method for groundwater exploration. It is based on the concept of subsurface determination, which can yield useful information on the structure, composition, and water content of the soil. Source: Bureau of Soils and Water Management
A geo-resistivity survey aims to determine the possible depths and thicknesses of aquifers as well as the depth of bedrock within the study area and to possibly pinpoint/locate preferable sites for deep water wells for subsequent drilling operations.
With this data, the engineering team will avoid uncertainty and unnecessary expenses, such as the cost of remobilizing the drilling operations, and appropriately plan materials for the construction and placement of the groundwater well.
Our Team led by Engr. Kristian with a decade of field experience and technical specialization on the topic went to the field . Using advanced geo-resistivity technology, our team surveyed the rugged terrain to locate potential groundwater sources. Despite challenges such as a low-yielding aquifer and limited survey space, we remained focused on uncovering viable water reserves.
Our efforts led to the identification of several promising groundwater sites. Using the survey data, we identified several feasible sites, each holding the potential to provide much-needed relief to the area. The georesistivity report also includes the accurate well design that contains the information about the exact location, aquifer depth, well depth, estimated yield, and cost of construction of the project. We never give up on this task and provide detailed data to help the clients determine a feasible location for a deep well.
Key Insights
Low-Yielding Aquifer: Previous studies indicated minimal water availability, making this discovery crucial.
Data Scarcity: With little prior research, our team explored largely uncharted territory.
Survey Challenges: Limited space required strategic and innovative survey methods.
Growing Demand: The increasing water needs of the community emphasized the urgency of our work.
Innovative Solutions: Advanced survey tools helped overcome geological and spatial limitations.
This is just the beginning. How can we refine our methods to locate more water sources? What other areas could benefit from similar surveys? Let’s collaborate to ensure a sustainable water future. Share your thoughts with us!
