Researches on Integrating Low-Cost Water Supply, Sanitation and Hygiene (WASH) Technologies with Housing Options

The researches include demonstration projects on ferro-cement houses with rainwater harvesting and other water supply systems, household water treatment and safe storage facilities, biogas digester septic tank for waste management, and low-cost wastewater treatment system combined with aquaculture and hydroponics.

The demonstration projects are meant to show that these simple, low-cost technologies help conserve water, prevent pollution, and enable families to adapt to climate change. It also shows that sanitation is neither expensive nor complicated and is achievable even in a difficult, congested, flood-prone urban environment or in an isolated peri-urban area or in a remote rural community. The efforts represent the cumulative learnings of PCWS from its field-based implementation experiences and its interactions with households and communities. PCWS hopes that the research results and demonstration projects help solve the lack of housing among low-income Filipino families as well as inspire the passing of enabling local and national policies for both human health and environmental protection.

Results and learnings from PCWS researches are used in promoting low-cost wastewater treatment for communities and households, which is a sanitation system that includes toilets, biogas digester septic tank, baffled reactor, anaerobic filter, gravel filter and lotus/fish pond. This is in the hope that sanitation become one of the priorities of national and most local governments, NGOs, communities, etc. PCWS is showing that sanitation technologies like wastewater treatment systems are not expensive nor complicated.

PCWS continues to do researches with partner organizations and communities on more appropriate housing designs with low-cost water supply and sanitation systems and how these could be made more affordable to low-income families.


 WASH Technical Assistance to Local Governments, NGOs and Communities

PCWS provides technical assistance to local governments, communities and NGOs to improve water supply, sanitation and hygiene. It also undertakes researches, trainings and consultancies in partnership with relevant organizations. PCWS- addresses the lack of knowledge, awareness and appreciation of low-cost sanitation technologies among policy makers. It also encourages increased investments in sanitation and the development of enabling policies. Local governments are called upon to include among their priorities the implementation of WASH programs.

Aside from responding to requests for technical assistance, PCWS presents low-cost appropriate alternative WASH technology options to create positive changes. It addresses the need to make sanitation affordable to low-income households. Expanding the range of water supply and sanitation systems presented to communities and households provide them with more options and information.
