This what I did in the past

    public class MyServerBehavior : IServiceBehavior {

        public void AddBindingParameters(ServiceDescription serviceDescription,
             ServiceHostBase serviceHostBase, 
             Collection endpoints, 
             BindingParameterCollection bindingParameters) {

        }

        public void ApplyDispatchBehavior(ServiceDescription serviceDescription,
                                          ServiceHostBase serviceHostBase) {

            foreach (ChannelDispatcher chDisp in serviceHostBase.ChannelDispatchers) {
                chDisp.IncludeExceptionDetailInFaults = true;
                if (chDisp.ErrorHandlers.Count > 0) {
                    // Remove the System.ServiceModel.Web errorHandler
                    chDisp.ErrorHandlers.Remove(chDisp.ErrorHandlers[0]);  
                }
                // Add new custom error handler
                chDisp.ErrorHandlers.Add(new MyErrorHandler());

            }

        }

        public void Validate(ServiceDescription serviceDescription, 
                             ServiceHostBase serviceHostBase) {
        }

    }

MyErrorHandler was my class that implemented IErrorHandler.
