    Maynilad Water Services Inc. will install 425 kilometers of new sewer lines from Caloocan to Cavite over the next 18 years or from 2020 to 2037 at a cost of P53 billion.

    These activities, however, are expected to cause traffic.

    Randolph Estrellado, Maynilad chief operating officer, said in a statement wastewater projects take a long time to complete since sewer pipes have to be laid at a lower depth compared to water pipes, some as deep as 14 meters below ground level.

    Estrellado said to minimize traffic congestion in project sites, Maynilad will use trenchless technology where feasible although said technology will significantly increase the cost to install the sewer network.

    The project will enable Maynilad to catch wastewater generated by its over 9.6 million customers and convey it to sewage treatment plants.

    The concessionaire is currently laying sewer lines in Valenzuela, Cavite City, Las Piñas and in barangays Cupang and Tunasan in Muntinlupa. Among the sewerage projects it completed recently are those in Pasay and Parañaque.

    Under its approved business plan, the company still has to spend almost P200 billion for wastewater projects from 2019 until the end of the concession period in 2037.

    Currently, the west zone concessionaire operates and maintains 588 kilometers of sewer lines and 22 wastewater facilities that have a combined treatment capacity of about 664,000 cubic meters per day. However, only about 20 percent of its franchise area is connected to the sewer network.

    Maynilad is the largest private water concessionaire in the Philippines in terms of customer base, covering the cities of Manila, Quezon City, Makati, Caloocan, Pasay, Parañaque, Las Piñas, Muntinlupa, Valenzuela, Navotas and Malabon; the cities of Cavite, Bacoor and Imus and the towns of Kawit, Noveleta and Rosario that are all in Cavite.
