4. An Overview
One of the four barrios comprising San Pedro Macati (Guadalupe, Olympia, Pio del
Pilar and Tejeros). It belongs to Makati City's first district and a member of the Northwest Cluster
or Cluster 3 of Makati. The barangay used to be composed of five sitios namely Carmon
(Crystal), Kasilawan (Suaboy or Bakahan), Singkamas, La Paz and Sta.Cruz (Paltok).
Based on the 2010 NSO census, there are 13,868 residents in Tejeros, which is
2.60% of the total population of Makati. With a total land area of 0.2832 square kilometers which
is almost 1% of the City’s land area and population density of 49 residents per 1,000 square
meters.
Up to now, Tejeros remains as one of the city’s main residential areas providing low
cost housing facilities for its residents (Makati Homes I and Tejeros Garden BLISS).

5. Mission Statement
Barangay Mission is the vision for the future. A 6-
year development through meaningful projects
and tangible activities to address the needs of the
community regardless of age; create jobs by
means of in-demand livelihood to improve and

7. Wastewater Challenges
VISION: Sustainable And Environmental Infrastructure For
Makati City
GOAL: All-encompassing safety & health in terms of
wastewater infrastructure
OUTCOME: Minimize domestic, commercial, and
industrial discharge to natural drainage
OUTPUT: Construction of communal sanitary toilet facilities for
communities without any means of proper wastewater
disposal

8. Selecting the Site
The selection of the proposal is grounded on the following considerations:
✓ Manageability of Geo-Political Unit: one of the smallest barangays in Makati
City with a total area of 0.2832 square kilometers (1% of Makati’s land area)
✓ Human density: as per the NSO, there are13,868 residents in the Barangay.
The population density is 49 residents per 1,000 square meters.
✓ Residential zoning: Brgy. Tejeros plays host to the low-cost housing facilities
such as the Makati Homes I and the multi-story BLISS
✓ Proximity to bodies of water: Estero de Santa Clara traverses the northern tip
of the Barangay, and it meanders directly to the Pasig River
✓ Presence of pockets for potential development: Urban build-up is prevalent
but there are identifiable areas for possible development & rehabilitation.
✓ Absence of Sewerage System: There is no update sewerage infrastructure.
Nearest distance of Brgy, Tejero to the Magallanes STP is 3.95 kms.

9. Possible Solutions
OUTCOME: Minimize domestic, commercial, and industrial discharge to
natural drainage
OUTPUT: Construction of communal sanitary toilet facilities for communities
without any means of proper wastewater disposal
COMMUNAL SANITARY TOILET FACILITIES Public Toilet
Onsite Septic Tank
Communal Septic Tank
Biodigester
Biolatrine

10. The Need for Latrines and Toilets
Proper sanitation facilities promote health because they allow people to dispose of
their waste appropriately. Throughout the developing world, many people do not have access to
suitable sanitation facilities, resulting in improper waste disposal.
Absence of basic sanitation facilities can:
Without proper sanitation facilities, waste from infected individuals can contaminate a
community's land and water, increasing the risk of infection for other individuals. Proper waste
disposal can slow the infection cycle of many disease-causing agents
Contribute to the spread of many diseases/conditions that can cause widespread illness and
death. Without proper sanitation facilities, people often have no choice but to live in and drink
water from an environment contaminated with waste from infected individuals, thereby putting
themselves at risk for future infection. Inadequate waste disposal drives the infection cycle of
many agents that can be spread through contaminated soil, food, water, and insects such as
flies.
