Problems Problems Pasig River considered the toilet bowl of Manila. An estimated 65% of the pollutants in the Pasig river come from households, 30% from the industrial sector and 5% from solid wastes. Metro Manila’s 11 million-plus residents, according to studies, produce roughly 440 tons of domestic wastewater every day. The river became the city’s toilet bowl. Worse, as the city continues to wage its battle against solid waste, the river also became the primary dumping ground. Currently, Metro Manila is reportedly producing as much as 7,000 tons or 31 cubic meters of trash per day. Out of this, about 1,500 tons is dumped daily (and illegally) on private land, creeks, rivers and the Manila Bay. One river clean up effort after another failed as the source of the pollution. Metro Manila’s population of over 10 million individuals continued to relentlessly dump waste and garbage into the river and its tributaries. The problem has gotten so bad that some parts of the San Juan river, one of the Pasig’s main tributaries, are already emitting methane.
The Pasig River (called Ilog Pasig in Filipino ) is a river in the Philippines and connects Laguna de Bay to Manila Bay . It stretches for 25 kilometres (15.5 mi) and divides Metro Manila into two. Its major tributaries are the Marikina River and San Juan River . The Pasig River is technically a tidal estuary in that the flow direction depends upon the water level difference between Manila Bay and Laguna de Bay. During the dry season , the water level in Laguna de Bay is low and the flow direction of the Pasig River depends on the tides. During the wet season , when the water level of Laguna de Bay is high, flow is normally from Laguna de Bay towards Manila Bay. The Pasig River used to be an important transport route in Spanish Manila . However, due to negligence and industrial development, the river has become very polluted and is considered dead (unable to sustain life) by ecologists . The Pasig River Rehabilitation Commission (PRRC) was established to oversee rehabilitation efforts for the river. Supporting the PRRC are private sector organizations i.e. Clean and Green Foundation, Inc. who implemented the Piso para sa Pasig (Filipino: A peso for the Pasig ) campaign.
