DEMAND
[PHOTO - The usefulness of
the Bayongan Dam of BIS 2 in San Miguel, Bohol, in 2007, will depend on the
efficiency of operations and management of BIS 1 and its reservoir. (Photo by B. Mejia) However, since the start of operations
in 1998, BIS 1 has performed poorly because water has been inefficiently used.
This has contributed significantly to the farmers' low incomes.From International Rice Research

The consistently increasing trend in water demand here in Bohol, the current
capacity of which is roughly estimated at 45,408 cubic meters per day (cumd)
"cannot sustain the projected demand," according to a study done by the Bohol
Integrated Water Supply System.
This supply capacity lags far behind the projected demand of a daily average
of 106,064 cubic meters, said the study.
Domestic use is the biggest rise in demand, from 59,985 cumd in 2010 to a
projected 94,789 cumd by 2015 and to 152,195 by 2035. This is followed by
commercial use, from 4,007 cumd to 6,000 cumd by 2015 and 17,273 cumd twenty
years later.
The institutional use of 2,996 cumd in 2010 is forecast to rise to 6,000 cumd
by 2015 and17,273 cumd by 2035, while tourism needs are computed from 1,954 cumd
in 2010 to 3,387 cumd in 2015 and to 5,249 cumd by 2035.
The total demand for water, if all demand categories are combined, would be
from 68,942 cumd in 2010 to 119,433 cumd in 2015 and to 203,011 cumd in 2035.
The study said that Bohol has about 20 river systems that were evaluated as
potential sources in the future. These are the rivers of Loboc, Abatan,
Wahig-Inabanga, CArood, Manaba, Alejawan and Ipil.
These potential surface water sources can be tapped to meet the demand
considering the groundwater or aquifers have already become salty due to
seawater intrusion, said the study.
The supply for more water is also getting critical to satisfy the growing
population and other important use for various demand categories in Bohol
province in the future, the BIWSS Master Plan pointed out.
This came as what the study called the "non-revenue water" (NRW) is being
considered in the projection. NRW may be considered as "wastage" or "systems
loss" including "leaks, pilferages, use of unmetered fire hydrants, technical
losses, unmetered services/fixed rate and other unmetered uses."
The study estimates about 20 percent for the NRW or unbilled water from 2015
onwards thus it has included the projection of water need of the populace in
terms of demand categories from year 2010 to 2035.
Demand category refers to nomenclature of sectors that need water during the
projected 25-year period.
These include domestic, commercial/industrial, institution, tourism and
industrial estate as against the so-called "NRW," average daily demand and
maximum day demand and yearly average day demand in terms of cubic meter per
day.
