Houston's floodwaters receded, now replaced by mountains of trash

City officials have asked contractors with debris-removal equipment to help.

— -- The floodwaters in Houston have mostly receded, but in their place stand mountains of debris.

Survivors of the catastrophic flooding from Harvey have shown their eagerness to rebuild and reclaim their damaged homes by hauling outside an estimated 8 million cubic yards of sodden drywall, flooring, furniture, appliances, clothing and toys, according to The Associated Press.

The massive piles are a reminder of the emotional toll for the residents whose lives have been upended by Harvey, but they also present a challenge to the city, which has promised to remove the debris as soon as possible.

The city has set out guidelines, including asking residents to separate the debris into six different piles:

- Normal household trash

- Vegetative debris including logs and tree branches

- Construction and demolition debris including furniture, drywall and building materials

- Appliances and white goods

- Electronics

- Household hazardous waste such as oils, lawn chemicals, batterieunderstand the process.

At least 136,000 homes in the Harris County flood control district, which includes Houston, were damaged by Hurricane Harvey officials said.

The cleanup job is so huge that the city has called on contractors with debris equipment to help with waste removal.
