Audit: Evaluation of Water Consumption in Selected Buildings at Cavite State University — Main Campus (Cluster IV). Undergraduate Thesis. Bachelor of Science in Civil Engineering. Cavite State University, Indang, Cavite. June 2019. Adviser: Engr. Cene M. Bago.
Water audit refers to the qualitative and quantitative analysis of water consumption
to determine water supplied into the facility as well as water lost and/or used within the facility. This study was conducted at Cavite State University — Main Campus and focused on the following buildings: Animal Science Building; Veterinary Medical Center; National Coffee Research, Development and Extension Center (NCRDEC) Building; Animal Production: Piggery A; and Animal Production Piggery B. The study was conducted from October 201 8 to March 2019.
The study addressed the need of Cavite State University on installing water meter
and gate valve on each building as well as conserving ground water and minimizing various causes of water losses. This project targeted to calculate the approximate water
consumption rate, water losses rate, percentage of losses of the selected buildings,
estimates of repair and approximate electricity rate loss caused by water losses.
The main objective of the study was to conduct water audit in selected buildings at
Cavite State University — Main Campus. Specifically, the project aimed to: (l) determine
the rate of losses and consumption rates; (2) identify and measure the specific locations of
water losses; (3) determine the causes of these losses; (4) develop the most effective and
economical water plan to mitigate these losses; and (5) calculate the estimated replacement cost of the faulty plumbing fixtures.
The study provided tabulated water meter readings, computations of water losses and consumption rates and their equivalent price in current water meter pricing in Indang, Cavite (See Appendix Tables l, 4 to 14 and 22). The study also provided floor plans, plumbing layout, and water losses marking for identifying the exact location of losses per building (See Appendix Figures 1 3 to 27). Finally, the water losses and consumption graph, water evaluation form and efficiency plan, cost estimates and documentation on installing a water meter were also provided to be able to determine the causes of the losses. (See
Appendix 2, 3, 5 and 6)
The water audit was conducted as per the water audit methodology of the American Water Works Association (A W WA). The total amount of the pipes, fittings and fixtures recommended for replacement estimates is P 38, 417.5 (see Appendix 5).
After the analysis and computations, the selected buildings were proven to have water losses that are problems to be resolved (greater than 30%). The researchers recommended the major repairs on the National Coffee Research Development and Extension Center and Animal Production Piggery A due to very high rates of unaccounted losses and faulty fixtures compared to the remaining three buildings. Researchers also recommended the water audit of remaining buildings; comparison of water audit before and after the repairs; and water audit of entire Cavite State University — Main Campus. The design project conducted could be used by other researchers as reference of procedure in conducting water audit.
