The island nation of Trinidad and Tobago has a significant need for improving its wastewater collection and treatment systems. The three largest cities on the island of Trinidad were provided with centralized wastewater collection and treatment systems in the 1960s. Since then, new housing developments installed separate sewer systems, or individual on-lot systems. The new sewers were typically connected to small package treatment plants that were never operated or maintained.

The Government of the Republic of Trinidad and Tobago has embarked on a program to achieve developed world status by the year 2020. One of the initiatives being implemented to achieve this status is to provide adequate wastewater collection and treatment for 75% of the population. This paper will present an overview of Malabar wastewater collection system project focusing on the design process and the advantages of using computer-aided design tools. The challenges of managing a complex design project are also discussed.
