Hello,
We have some standing water (condensate) which comes through the gutters onto the driveway around the building, in some areas because the road is not sloped in the direction of the drain the water remains on the road (it does dry but we do not know how long it takes the water to dry) . Since we are located in Houston as the weather is warm / hot I don't think the water remains there for long periods of time, by afternoon, we can see the dried water marks on the road.
I would like to know from you all if this is an issue? In the BRC Interpretation for section 4.1.2 it says - external drainage is expected to be able to deal with normal quantities of rainfall without long-term pooling of water. So, in my mind I think it does not pose any risk to the product or process.
Also, there is a sidewalk running across the building and the gutters are positioned outside the sidewalk, that way there is no standing water immediately close to the building.
All your thoughts will be appreciated.
Thank you,
