This project consisted of performing the condition assessment of the existing sanitary sewer system and the design of the completion and rehabilitation of the Sábana Seca Sanitary Sewer System. The Puerto Rico Aqueduct and Sewer Authority had not been able to complete the project construction in two previous attempts and requested that ENTECH provided the sewer system evaluation and design services required to complete the project. The first tasks were to assess the condition of the existing sanitary sewer system by performing manhole and pipeline inspections and to identify areas where new sewer lines were required. In summary approximately 3 miles of sanitary sewer and 110 manholes were inspected using CCTV and Zoom Cameras. Based on the results of the assessment manholes and sewer segments were selected for rehabilitation and the alignment of new sewer lines was determined. The design consisted of the preparation of construction documents for the installation of approximately 6 miles of sanitary sewer line between 8 and 18 inches in diameter and the rehabilitation by trenchless methods of approximately 2.5 miles of pipeline. This project was funded by EPA’s State Revolving Fund and had a construction cost of approximately $7 Million.
