Capstone Project Scope

Capstone Project Proposal #1

Too-Big (Water Usage Monitoring Tool)

  • Project Rationale

Water conservation has been a continuing drive because of the adverse effect the humanity will experience once water, particularly drinking water, is gone.  A case study was conducted by the proponent to determine the average consumption of the concessionaires of Digos Water District located in Digos City, Davao del Sur.  Fortunately, the respondents, which comprise a small portion of the total active connections, had shown that water usage has been minimal.  Although said case study was inconclusive to depict the general consumption pattern of the residential concessionaires nor the reasons why the respondents’ use was minimal usage verified, the proponent had theorized that if said concessionaires will be visually made aware of their consumption for a certain period, at least they will save water.

  • Scope

Too-Big will be included in concessionaires’ water bill which will graphically show the consumption of a concessionaire for a particular period preferably, it will show the monthly volume starting January and ending on December.  The initial target of the said scheme is the Residential category concessionaire or those which used water for domestic purposes only.  However, it may be wise to indicate a graph for Commercial and Government concessionaires so that they may be aware as well.  It has been observed by the proponent that most Government concessionaires would not pay attention of their usage due to the belief that it is not their personal money anyway that will be made to pay for their office’s bill, thus the necessity of attaching the Too-Big mechanism on their billing as well.

Capstone Project Proposal #2

Data Mining on Leakage Frequencies

  • Project Rationale

Water wasted through leaking pipes is a worldwide concern that needs to be addressed the soonest time possible.  This wasted water is called Non-Revenue Water (NRW) – a nomenclature used by the water sector.  It is defined as the difference between the volume of water put into a water distribution system and the volume that is billed to customers, and is comprised of three components, (1) physical (or real) losses which comprises leakage from all parts of the system and overflows at the utility’s reservoirs caused by poor operations and maintenance, the lack of active leakage control, and poor quality of underground assets; (2) commercial (or apparent) losses which are caused by customer meter under-registration, data handling errors, and theft of water in various forms; and (3) unbilled authorized consumption which includes water used by the utility for operational purposes, water used for firefighting, and water provided for free to certain consumer groups.

Nearly 60% of NRW in the developing world is due to physical losses, and around 90% of water that is physically lost from leaks is not readily seen on the surface.  Though the leaks may be evident a few months or even years thereafter, this is equated to millions of gallons of water lost in leaking, not to mention the hazards to health it may cause such as when microbes make its way in the pipelines thru leak openings.  Furthermore, this would cause depletion in the supply of drinking water which is already on the brink of over-usage when the water source vis-à-vis the world population is to be taken into consideration.

  • Scope

With the current set-up of small water districts, it is more often difficult to gauge the actual volume of water lost in leakages especially with the limited historical data on the pipes and the undetermined age of the leak – how long has the leak manifest in the pipelines before it was discovered.

A system will be developed that will mine data for pipe leakages and pipe aging.  Through time and with enough data, it will be easy to determine the period of the natural wear and tear of pipes on average, assuming the absence of factory defect on said pipes.  The system will then give an analysis on which pipes would be pulled-out for repair or changed with a new one even before the presence of leaks.  Although this would entail cost on the part of the water district, this shift would greatly mask the higher importance of water quality and water conservation over capital expenditures.

Capstone Project Proposal #3

Water Interruption Forecasting

  • Project Rationale

Nothing is more frustrating than water loss in the middle of your shower or washing of clothes – a water utility is sure to be bombarded with complaints and curses until and unless the water supply will be restored immediately.

Water is a primary resource, essential for survival of all living things.  Although drinking water in the whole world is diminutive in quantity, it is expected to be available every day for consumption of human beings, hence, a water utility should be able to keep up with that expectation.  However, a water utility will experience water loss or low water pressure sometimes due to foreseen or unforeseen causes.  Prior information to its consumers plays a vital role in household preparation for the imminent water loss or low water pressure.

  • Scope

The water utility, particularly Digos Water District, had its historical data on its scheduled water interruptions such as flushing, pump pull-outs and cleaning of reservoirs.  Nevertheless, most of the data are scattered, if not lost, within the concerned division’s files resulting to decreased historical values in the contained information.

This project would mine the data on the reason of water interruptions, the location, the estimated size of affected households, and the duration of said interruption among others.  It would also accept data entries on this regard for updating purposes.  It will then display the history based on areas wherein the water loss are experienced and forecasting the likelihood of occurrence of the water interruption in the future.
