Water loss in Downtown Oklahoma City, Midtown

The first thing to do is to turn off the water to the building. Some people may have to be without water for a time but it is better than the alternative. 
Next be sure to call a mitigation company. The goal of mitigation is to remove the water and start the drying process.
Also be sure to call a plumber to fix the source of the water leak. This will allow water to employees and clients.
Next, make sure to call the insurance company. Commercial insurances will want to know that action is being taken to lessen the cost.
