It will be several months before we find out what caused the flooding at the city's East End sewage plant. Spokesperson Darrell Matson says it's all part of a consultants study of the May 28th flood which is taking place now and will be explained to city councillors Monday evening. He says the final report isn't expected to be ready for 3 or 4 months. Included in that report will be finding out what caused a leak in the sewage plant.
