On Going Projects
To optimize wastewater distribution within Valenzuela, Maynilad commissioned LEI to create a combined Sewerage Interceptor System.
The proposed sewerage network will intercept wastewater flows from existing drainage outfalls and certain creeks of Valenzuela city, and conveyed to a proposed STP located at Brgy. Marulas in the southwest part of Valenzuela.  
The interceptor sewer is designed to cater to the equivalent dry-weather flows from the catchment. The project covers an area of approximately 1,371 hectares, with an approximate population of 340,000 residences.
