What are the conditions that triggered the landslide in Payatas landfill?
The major reason for the landslide is the low waste density. The low density reduced the surface flow of rainfall water and resulted in a high rate of water infiltration into the waste. The leachate water decreased the shear strength by mobilizing pore water pressure and triggered finally the failure.
Who is the responsible for the Payatas tragedy?
Quezon City government
MANILA, Philippines — A local court found the Quezon City government liable for the garbage dump collapse in Payatas, nearly two decades after the tragedy that buried more than 200 people alive.
Why is slope important for a landfill?
The slope of the ground upon which the landfill is placed also is important. Increasing height, steeper cover angles, and construction and steeper slopes must be compensated for to insure stability. Berms placed at a landfill’s edge resist waste movement. Increasing berm size can provide more stability.
Why is there a need for dumpsites such as the Payatas dumpsite?
Landfills, even if they are not the best solution for waste management, have made a significant contribution to reducing the environmental impact of excessive waste production in a country already without open air dump sites, but where each inhabitant produces on average about 500 kg of waste per year. Ours.
What made it difficult for rescuers to save lives in Payatas?
The badly decomposed bodies were placed en mass in black plastic bags and left on an outdoor basketball court for family members to try and to identify the victims. The dangerous conditions and the incredible stench made it very difficult for rescue workers to work among the rubbish and debris.
What is topple landslide?
Topples. Topple failures involve the forward rotation and movement of a mass of rock, earth or debris out of a slope. This kind of slope failure generally occurs around an axis (or point) at or near the base of the block of rock. A good example of a site experiencing topple failures is Aldbrough, UK.
How many dumpsites are there in the Philippines?
There are 237 operational SLFs in the country and 11 are under construction.
What is residual waste?
Residual waste is nonhazardous industrial waste. It includes waste material (solid, liquid or gas) produced by industrial, mining and agricultural operations. It excludes certain coal mining wastes and wastes from normal farming activities.
Why dumpsites are needed?
Keeps Hazardous Waste Segregated Landfills provide a place to dump recyclable and non-recyclable waste separately. Also, they provide a place to keep more hazardous materials that need to be segregated from the public.
What is purpose of landfilling the waste?
Landfills are built to concentrate the waste in compacted layers to reduce the volume and monitored for the control of liquid and gaseous effluent in order to protect the environment and human health.
How do you stop slope creep?
Cover exposed soil with a variety of plants — trees, shrubs, perennials and annuals — to create a barrier that stops soil movement from both wind and water. The plants’ roots will hold the soil in place, as well. Lay mulch or stone between plants to provide additional coverage of exposed dirt.
