Must a hazardous waste warehouse have sump pits instead of floor drains? Are there any regulatory requirements?
Hazardous waste warehouses usually require sump pits to prevent potential leaks from contaminating surface water and groundwater. The design of the sump pit allows it to collect and store leaked substances, facilitating subsequent treatment. The floor drain is directly connected to the drainage system, and in the event of a leak, it may allow pollutants to enter the environment directly. Generally, the regulations and requirements regarding the storage of hazardous waste specify necessary environmental protection measures, including the installation of sump pits; however, specific requirements must be referred to in local environmental protection laws and relevant standards. .
Standards for Pollution Control of Hazardous Waste Storage GB 18597-2023
Can sump pits also be installed in warehouses for Category A and B items? I did this at a provincial chemical engineering design institute in a developed area: the liquid was sent via siphon to an outdoor ditch and then to an accident pond.
“Send it outdoors via siphon to the ditch, and then to the accident pool”? In practice, it’s not that complicated.
It can be set, provided that your drain leads to a collection tank.
