To Tatou Vai Limited (TTVL) was a water utility established in 2018 to deliver potable and reliable water supply service in Rarotonga, Cook Isalnds. In December 2021 was formalized through the To Tatou Vai Act as a not-for-profit statutory corporation. The objective is to ensure assets are managed well, replacements are planned for reliability, and the cost of operations are recovered.
