Can steam condensate be discharged directly?

Previously, rainwater could be discharged directly; this was called clear water drainage. It seems that the term for cleaning out water has been discontinued; it’s no longer allowed to discharge rainwater. Find a way to collect it.

It depends on the amount. With such a question, it’s likely referring to small-scale discharge of some hydrophobic substance; as long as the property owner agrees, there are no regulations requiring its collection

It cannot be discharged into the rainwater drainage system. Since steam condensate is at a high temperature and under pressure, the wastewater discharged contains a large amount of water vapor. If it is discharged directly into rainwater manholes, this water vapor cannot dissipate easily within those manholes, which is detrimental to the drainage process. Furthermore, it is not allowed for environmental and energy-saving reasons; it represents a waste of resources. It can be completely recycled.

It should be recycled; a small amount discharged into the rainwater drain is fine.

There are no relevant regulations, and since the condensate is not polluted at all, it can be discharged directly without any restrictions on scale. But it seems like a waste of resources. If possible, external technical teams can be brought in to handle the condensate water, implementing a tri-generation system of cooling, heating, and power generation in order to maximize the efficiency of utilizing that condensate water.

It can be collected to be used for cleaning floors, heating materials, heating water systems, and replenishing cooling water.

A large amount of the heat-traced steam traps either ended up in the nearby grasslands or flowed through underground sewage pipes to the wastewater treatment plant. I also knew that there were requirements regarding the water temperature of the water sent to wastewater treatment plants, but over all those years this has not resulted in higher water temperatures reaching those plants (as underground pipes help to cool the water). In fact, in recent winters, wastewater treatment plants have often requested that the discharge water from upstream sources have a higher temperature due to low water temperatures. Later on, the main reasons for preventing steam condensate from being discharged directly were as follows: 1. Energy conservation, by recovering steam condensate in a closed system ； 2. Reduce the water inflow to the wastewater treatment plant, thereby lowering its operating costs ； 3. Prevent large amounts of rainwater from entering the wastewater treatment plant through the condensate discharge outlets. 4. Avoid high water temperatures from vaporizing odors from the pipes along the route, thereby reducing unpleasant smells in the factory area.
