Hiraya’s expertise spans across the different areas of water supply and wastewater management. The focus is on Smart Water Management and Water and Wastewater Treatment.

Hiraya’s smart water management flagship product is R-TAP, and intelligent pressure management system that optimizes water distribution. R-TAP started through Ideaspace Foundation’s National Technology Startup Competition in 2014. The product has since gained recognition from different local and international institutions including IBM (Singapore), Asia Impact Investment Exchange (Singapore), The Department of Science and Technology (DOST, Philippines). We take pride in this level of expertise that has allowed us to challenge the norms and innovate to avoid inefficient ways of implementing Data Acquisition, Monitoring and Management, and SCADA systems.

The water and wastewater treatment expertise of Hiraya is grounded on both solid academic mastery and industry experience. With the list of technologies within our expertise, our clients are assured that the most appropriate treatment processes are proposed, so as to assure sustainable management of water and wastewater at the least capital cost and lowest operational and maintenance expenses.
