For the renovation of the old factory area and the upgrading of wastewater treatment, it is planned to build wastewater collection tanks within the required safety distances between factory buildings and warehouses; these tanks will be about half a meter above the ground level. Is that okay?
It also depends on the nature of your factory buildings and warehouses – whether they are open or semi-open – what type of medium is used, as well as the properties of the materials stored in the warehouses. Since these details aren’t specified, it’s difficult to make a judgment. Additionally, it matters what type of sewage collection tank you have: is it an oil separation tank, a sun exposure tank, or one used for collecting rainwater and domestic sewage, as is common in practice. But if fire separation distances are not taken into account, it is essential to ensure that fire exits are not occupied. It is definitely not allowed to block fire exits.
There are issues, as different fire protection classifications require specific fire separation distances from other buildings; therefore, there are also requirements for fire separation distances between sewage collection tanks and warehouses as well as factories. The above are merely personal opinions and for reference only!
Explanations to the provisions of the Code for Fire Protection Design of Buildings: Fire separation distance refers to the spatial gap between different buildings; it serves both to prevent the spread of fire from one building to another and to ensure that fire fighting and rescue operations can be carried out conveniently and safely. Moreover, some sewage tanks themselves also need to meet fire and explosion prevention requirements.

Workshop-level wastewater collection tank, productive wastewater; fire hazard unknown; likely contains small amounts of flammable solvents. The factory building is classified as Class A.
For the fire separation distances of sewage tanks containing flammable liquids, refer to Tables 5.2.1 and 5.4.3 of the Stone Regulations.
