a build-operate-transfer arrangement between the municipal government and a private
company. The revenues from the user charges shall be used for financing the MOC of
the ECOSWAM service only. The Tuba municipal government wanted to know which
of the following options it could afford to provide to its constituents:

The researchers calculated the costs in consultation with the Tuba local
government, SWM officials of neighboring local governments, SWM experts and the
SWM plans of similar LGUs. The costs were divided into three stages: (1) waste
segregation and reduction, (2) collection and transport and (3) waste disposal operations
and management in a sanitary landfill.
The cost estimates provide a “snapshot” of the initial years that the ECOSWAM
service shall be provided. Yearly costs are expected to increase with an increase in
inflation, in the growth rate of the population, the local economy of Tuba and its waste
generation and the wear and tear of SWM equipment, vehicles and facilities.
3.6. Funding Gap
The researchers estimated the funding gap or the difference between the marginal
revenues (MR) and the marginal costs (MC) per year per scenario. This is the amount
that the Tuba municipal government will have to subsidize in the provision of the
ECOSWAM service. The estimates of the funding gap only provide a static picture of
the SWM continuum. It is expected that unless the garbage fees are increased after some
years, and given that the costs of the ECOSWAM service rise each year, then the
funding gap will widen.
4.0 PROFILE OF THE RESPONDENTS
4.1 Environmental Knowledge, Attitudes and Perceptions (EKAP) and
Practices
The households and business establishment ranked improper garbage disposal as
the first and most important environmental problem that Tuba needs to address;
followed by difficult access to clean drinking water and water pollution in rivers. Fifty
two percent of the households and 59 percent of the business establishments have no
prior knowledge of the Ecological Solid Waste Management Act or RA 9003.
