The work, which is part of the Federal Sanitation Program (Profesa) of the National Entity of Water Sanitation Works (ENOHSA), reaches 10 percent progress. The planned investment amount is 168,287,840.98 pesos and an execution period of 365 days is expected. The company that carries out the work is Traza Construcciones and the total workforce is 20 people.
The director of Sanitary Works of the province of Entre Ríos, Jorge Trupiano, remarked that "this work will improve the sewage effluent treatment system, the relocation of the treatment lagoons in another property is planned, so that the population does not have to live with bad odors or spills on public roads.”
Work details
Regarding the work to be carried out, it was specified that, these days, the open-pit excavation is being started to subsequently carry out the pipe. The steps entail the cleaning of the land, manual profiling, filling, compaction and transport of the surplus that is used later. 1200 meters of 160 mm PVC sewage pipe was placed.
The same excavation work is done for the installation of the manholes, bottom, body, frame and cover are applied for their construction, their depth is 2.50 meters and a total of 15 have been executed to date. .
The main objective is the execution of treatment lagoons to complement the network, due to the incipient urbanization of San Salvador. It includes the expansion of the sewage network and the respective home connections, in order to solve the sanitation problem of the current and future population.
The construction of a sewage pumping station is planned in the southern part of the city, which will be used for the collection and pumping of the sewage network, which due to its natural slope is unable to be transported to the final treatment system.
Likewise, the project will be complemented by a pumping station and discharge pipes between the pumping station and the sewage stabilization ponds in the town of San Salvador, taking into account the currently populated areas and their future growth.
The system consists of stabilization ponds located outside the urban ejido, where the sewage effluents will arrive conducted by the corresponding discharge pipe of the lifting station, where it receives the discharge from the network collectors by gravity. Once the raw liquid has been treated in the stabilization ponds, they are deposited by gravity into a receiving basin of the Casafuz stream, whose layout is located 200 meters from the pond site. |
