Project Title : Design and Construction of two units Potable Water System Location : KSU Bulanao Campus, Tabuk City, Kalinga
1. PROJECT DESCRIPTION
1.1 Background and Rationale:
Along with the conversion of the former Kalinga-Apayao State College into Kalinga State University, a series of physical development is likewise attached to this growth. More than ever, the need for support facilities in the form of infrastructure like buildings has to be addressed. Likewise, sufficient and reliable water system must be established.
Currently, The Kalinga State University Bulanao Campus water system is relying on three functional elevated tanks aside from the newly constructed two units deep wells. It is observed that these deep wells could not sustain continuous pumping since it is being shared by number of facilities. Water supply for facilities is being interrupted since these deep wells have to be recharged prior to re-usage. It is therefore recommended to construct additional two units of potable water system which includes elevated water tanks to address water insufficiency and anticipating the rise of the new buildings as well.
Water Resource Planning (WRP) for the construction of the two units potable water system is a mandate to establish the most feasible location of the two underground water source for academic area, administration building dormitories/housing and research area. Thus, implementation of a complex WRP will be significant in designing a reliable water supply system that could provide an uninterrupted quantity flow of water, adequate water pressure, a quality of water, free from objectionable taste, turbidity, odor or chemical detriments and water that is bacteriological safe for drinking which is readily accessible to end users of the Kalinga State University
1.2 Specific Objectives
The specific objectives of the project are the following:
1.2.1 To come up with a Water Resource Plan for the design and construction of two units potable water system at KSU Bulanao Campus;
1.2.2 To conduct subsurface water exploration for the most feasible location of the underground source for the two units of potable water system;
1.2.3 To provide signed and sealed report and calculations relative to the subsurface water exploration;
1.2.4 To provide signed and sealed structural analysis, structural details, drawings, plans and specifications relative to the Construction of two units potable water system;
1.2.5 To provide a detailed cost estimates of the Construction of two units potable water system;
1.2.6 To integrate Solar panel system or windmill as a form of an alternative electrification for the operation of this proposed two units potable water system; and
1.2.7 To construct two units of potable water system in Bulanao Campus providing an uninterrupted quantity flow of water, adequate water pressure, a quality of water, free from objectionable taste, turbidity, odor or chemical detriments and water that is bacteriological safe for drinking which is readily accessible to end users of the Kalinga State University.
