POSSIBLE SOLUTION TO ODOUR FROM BATHROOM FLOOR WASTES

‘Sewerage’ odours emanating from bathroom floor wastes continue to be a source of concern for many residents along the coastal strip however I think that the cause and remedy has been found.

It appears that the odour isn’t coming from the sewerage system at all but is actually caused by festering contaminants within the household piping system which is exacerbated by the ‘hardness’ of the water that’s treated through the Kalkie Water Treatment Plant (WTP). I won’t go into all the chemical details because if you’re like me, it’ll make your head spin but this is how I understand it in layman’s terms…..

Most soaps used in showers, baths and basins usually dissolve completely in household water and exit properties into the sewerage system. A U-Bend under the floor waste creates a water trap which then prevents odours returning from the sewerage system into the house.

Because of the ‘hardness’ of the water supply through the Kalkie WTP, common soaps don’t fully dissolve and as a result, over time they tend to create a fatty substance which can line bathroom pipes and form a floating layer on top of the water on the inlet side of the U-Bend (shown in red on the attached drawing).

Whenever a shower, bath or basin is used, the discharged water (which isn’t pressurised) can’t force this floating film through the water trap and it simply remains floating on the inlet side of the trap whilst the discharged water runs under it.

Over time this fatty film  also collects unmentionables such as body fats, hair and any other gunk that goes down the drains. During the warmer months, this tends to fester and emits an odour back into the bathroom which certainly smells like it’s coming from the sewer even though it’s not.

Council’s ultimate aim is to be able to effectively treat the ‘hard water’ before it gets to homes however the plant required to do this is extremely expensive and it will be subject to budget allocations. The new pipeline from the Mellifont Street facility to the Kalkie WTP will however dilute the ‘hardness’ and residents should see an improvement in their supply once the project is completed.  (I should point out here that the ‘hardness’ of the water is not related to the funny taste that we get regular complaints about however the Mellifont Street supply will improve both issues).

In the meantime, I’m advised that periodic small doses of Soda Ash (http://www.wisegeek.org/what-is-soda-ash.htm) down the shower or floor wastes will neutralise any contaminants and resolve the issue.

I’d be interested to hear from people who are experiencing these odours to see if this treatment does in fact rectify the problem. Also, please note that the diagram above is very simplistic so apologies for any inaccuracies in the finer detail.
