This regional conference in Trinidad and Tobago (Water Loss 2023) is the first ever IWA Water Loss Conference in the Caribbean. It is jointly organised by the IWA WLSG, the Water Loss Specialist Group of the Caribbean Water and Wastewater Association (CWWA), the Water and Sewerage Authority (WASA) and the Ministry of Public Utilities (MPU). It is a highly specialised conference addressing the needs of water utilities in the Caribbean, who are under pressure to significantly and sustainably reduce water losses (and thus carbon emissions) during the next 7 years. The conference is expected to attract about 150 participants from the region. Some of the world’s leading experts in the field of Non-Revenue Water Management are expected to attend, and will discuss the latest developments, strategies, techniques and applications of international best practices and their applicability to the Caribbean.
