A consultant's report into the May 28th flood concludes that the Atlantic Avenue water treatment facility was overwhelmed with the amount of rainwater that came through the facility. It says the pumping system wasn't designed to deal with the flooding event and resulted in a systematic failure in the plant. The result was the flooding of hundreds of basements in the city most of which were in the East End where the treatment plant is located. The report recommends almost one and a half million dollars in upgrades in order to prevent such an occurrence in the future.
