History


Early years

On December 21, 1578, water reached the fountain in the Plaza Mayor for the first time. From then on, the waters of the La Atarjea springs were used. The population of Lima was supplied with pylons. In 1855, a group of Peruvian businessmen, with the support of President

That year, the Superior Council of Drinking Water of Lima () was formed, later called the Municipal Board of Drinking Water of Lima (). In 1918, this institution undertook the construction of the La Menacho (El Agustino) reservoir with the application of alumina to the water and the expansion of the distribution network.

handed over the administration of the water service to ''The Foundation Company'', later passing it to the Public Works Directorate of the Ministry of Public Works. In 1930, the Superintendency of Drinking Water of Lima () was formed, as a dependency of the Ministry of Public Works and Development. The first Water Treatment Plant was also built, which came into operation on July 28, 1956.


Later years

On June 8, 1962, the Lima Sanitation Corporation (, Cosal) was formed. This is the date on which the company celebrates its anniversary, when the first public sanitation company with administrative and financial autonomy was formed. Seven years later, on March 21, 1969, Cosal was restructured and the Lima Sanitation Company (, ESAL) was formed as a decentralized public body of the Ministry of Housing. On June 12, 1981, the National Service for Drinking Water Supply and Sewerage (, SENAPA) was created, modifying the structure and function of ESAL, establishing the Service for Drinking Water and Sewerage of Lima (Sedapal) as a subsidiary company of Senapa. During those years it absorbed the municipal water companies of
