I own and have an optometrist's office in a building that is over 100 years old. It is located in the downtown area of a small town in Western Oklahoma. We frequently have a problem with sewer gas in our building. One time when my staff and I were out of the office it was very bad and was mistaken for a natural gas leak. At that time people from the gas company, firemen and other city officials were all over the building.
Someone discovered some cast iron pipe in a cellar that was cracked on top. I have had it replaced but things have not improved much.
Here are some other details about my situation:
Along with my optometry office, there is a chiropractor and a T-Shirt shop. None of us have a lot of traffic.
Other downtown businesses have the same problem including the county health department who is in and almost brand new building.
The smell is worse if the wind is out of the south.
There is a clean out between my building and the city sewer. This is on the south side of the building. I removed the lid from this yesterday hoping any gas generated in the city sewer would escape there before entering my building. This morning, the smell was as bad as ever.
The smell is unpleasant and gives new patients a horrible first impression. I don't know what to do.
