Piping applications


No matter when or where, water is one of our most crucial resources. In any project, it is important for potable water distribution systems to be clean, safe, and long-lasting.

Ottilie Marketing introduced the Philippines’ first leak-proof plastic waterline system in 1994—changing the game for the piping industry. Now with over 20,000 projects under our belt, we are still continuously expanding our portfolio to offer quality piping systems for a wider range of water distribution applications across all price points.



Whether it’s for public or private water mains, HVAC, or land development applications, an ideal main water distribution system should be able to withstand prolonged stress, ensure efficient water delivery, and possess a long service life—all while being cost-effective.

HDPE piping systems have the lowest costs for operation and maintenance among conventional potable water mains because of its leak-proof technology, installation flexibility, and 50-year design lifespan.

Water Distribution

Water distribution systems play an essential part in our daily lives: they make it possible for us to enjoy clean water whenever we need it. For everyone’s safety and to ensure high hygiene standards, water distribution systems need to be leak-free, non-toxic, and resistant to corrosion.
