A short article in Green Futures, published by Forum for the Future, with a spectacular double page spread photograph, prompted a web search.
The website of Habitat International Coalition, which has been active in the area, relates that Paco Market, on the edge of the Estero de Paco, was once a bustling centre of commerce. Local fisherman took their day’s catch directly from the ocean down the Pasig River to Estero de Paco, one of its largest tributaries. After WWII, the Pasig River began to become polluted and the Paco Market was neglected for years; the market vendors threw all their garbage and waste into the river and squatters moved in, building directly on the banks of the sewers, impeding the flow and ‘further deteriorating the water quality’.
Within a year, the Paco market and Estero de Paco have been transformed into a world-class market and a clean tributary. The garbage was removed by the River Warriors – volunteers living beside the waterways -who cleaned the water with small nets and ensured that no more garbage is thrown into the river. The shores now have vetiver grass growing to prevent erosion and coir has been mixed with a helpful bacteria to decompose garbage and treat the waste water and sludge. Air is being pumped in so that the water can sustain life and fish can return.
