hi....
i'm hoping this is a good email address, but maybe you could forward this somewhere more appropriate if it isn't?
i'm renting a basement apartment at cataraqui and marion and am getting a few problems and am just trying to determine the cause. my landlord claims there are separate storm and sanitary lines, and i have no reason to doubt him. his logic is that rainfall should not cause the toilet to drain slowly, and he's consequently not taking me seriously. i understand his argument and why it shouldn't happen.
however, i'm a scientifically minded person and i've been able to demonstrate the following:
1) the slow down is correlated with the rain. that is, the toilet drains slowly after a rain and drains normally once the rain has dried up. so, while a block might exist, it's not the primary cause of the slow down.
2) the amount of slow down is proportional to the amount of rain. that is, when it rains a little, it slows down a little. when it rains a lot, it slows down a lot.
despite understanding that these systems ought to be separated, my brief and aborted training as a physicist tells me that when you have things that are correlated in a proportional manner, it is very likely that there is a causal relationship between them. that is, i have a high degree of certainty that the rain is causing the toilet to drain slowly in a manner that is proportional to how much rain is falling.
while it's august right now, the proportionality has me concerned about spring runoff, which is of course substantial in canada. i have every reason to think that that a lot of snow melting could back up the toilet and cause a horrible mess.
now, i've talked to the neighbour next door and he's confirmed that he's actual dealing with back ups through the pipes, which is a worse problem than i have. he's convinced that the problem is related to sewer replacement on wyandotte down the road. this only makes sense to me if they might have put the storm through the sanitary as a temporary measure. is that something the construction team has done in the short run?
i'm leaning towards a different cause. at roughly the same time that the problem started, the house across the street experienced a significant fire. the property has been completely shut down. i suspect the sump pump is not running, the basement is flooding and it's draining into the floor, which is connected to the sanitary and this is causing the backup. the issue i'm running into in having this make sense is related to the volume of water running through the floor drain. it's a pretty big property - it was an apartment before the fire, but it would have been a five or six bedroom house some time in the middle of the last century, and it has a very big backyard. so, there's a potential for a large volume of water to be coming into the floor drain. how likely do you think it is that this could be the root of the problem? how big a problem do you think this is going to cause in the spring, if it's not addressed now? and what is the better solution for this - running a sump pump on an abandoned property, or closing the drains off? how does the city deal with something like this, if it's determined to be the cause?

I would like to clear up a few points in your email.
While your landlord may be correct in that the house may be serviced by separate storm and sanitary connections (I can't confirm that), both these connections would outlet to the same combined sewer in the road. There is only one sewer Cataraqui and one on Marion, and they are both combined sewers meaning that they accept both rain water and sewage.
With respect to the Wyandotte project, there is no sewer work being undertaken as part of that project. Windsor Utilities is replacing the watermain and services and the City will reconstruct the pavement following that work. This project would have no impact on the sewers servicing your property.
You are most likely correct in that there is a correlation between rainfall and the slow running plumbing in your house. This is due to the combined nature of the sewer that services your property. During rain events, combined sewers fill with rainwater and therefore have limited capacity to accept flows from buildings.
With respect to the apartment building across the street from you, all rainfall runoff from this property would have entered the sewer system via foundation drains prior to the fire, so the fact that the basement may have flooded and the water is now entering the floor drain would change the drainage pattern very little. In fact, rainwater entering the sewers from this property would be very small in proportion to that coming from the catchbasins draining the roads in the area.
With respect to abandonment of the connections servicing the apartment building, that would be addressed when the building is demolished by the Building Department. If you have concerns regarding the state of
the building, please contact the Building Department via 311.
Hopefully, this answers some of your questions. Please contact me if you want to discuss this matter further.
Sincerely;
