The Legacy of Ecosystem Technologies speaks to the history and context of the Philippine property development sector and its relationship with water utilities:
The Philippine development sector context differs from counterparts in the developed world in that due to severely lagging public sector infrastructure development of water supply, and especially sewerage and sanitation, the private development sector was legally mandated to treat its own sewage and wastewater, as part of regulation of construction as well as facilities management.

With high population growth also contributing to rapid urbanization, combined with the lack of public sector sanitation services, it presented a unique challenge for developers with finite space to work with. Ecosystem designed its proprietary Sequence Bio Reactor for this context. The key innovation is that the biological process does not emit toxic, flammable, and explosive gases, eliminating the need for expensive sensors and gas removal equipment. This meant that the treatment plants can be safely built and operated underground.

Developers no longer had to set aside valuable space just for sewage treatment above ground, which then allowed for uninhibited architectural design and uninhibited usable space for residents, tenants, and guests. The development therefore fulfills its regulatory obligations and moreover makes its contributions to environmental sustainability.
The property development sector thus continued to build and build, supporting the overall economic growth of the Philippines while being supported by a Filipino technological innovation, which was contributed by Ecosystem Technologies.
