Drinking Water Supply and Sewer System for San Pedro Sula and Tegucigalpa - Honduras

In its role as Technical Consultant for “Aguas de San Pedro, S.A. de C.V” (the concessionaire company of the aqueduct and sewerage system of the city of San Pedro Sula up to 2031), LOTTI completed various assignments for the improvement of the drinking water supply system and the wastewater collection and treatment system, thus enabling the service to be provided in an efficient manner while guaranteeing high standard health and environmental conditions for the city’s population. A general plan of the drinking water system up to the year 2031 was developed, in order to enable ASP to have a technical and economic planning instrument for the entire period of management of the system. The plan presented an investment proposal aimed at guaranteeing the growth of the system within the pre-planned levels of service, optimizing the functioning of the existing system and ensuring that the construction of the new works is in compliance with the principles of technical functionality with the minimum cost of investment and operation.

At the same time, a general plan for the sewerage line and the treatment of wastewater was developed to provide for the total collection and partial treatment within the 2031 time frame, also including the collection and treatment of industrial wastewater. for the works included in the general plan a preliminary design was conducted. This involved 3 treatment plants for an overall average capacity of 2,100 l/s (for a total population of approximately 1 million) and utilizing UASB technology with energy recovery from the biogas produced, works for containment and protection from flooding, 300 km of sewers, 4 new pumping stations and 3 rehabilitated pumping stations.
