Narrative:

A CRJ2 checked on my frequency (departure) and immediately said they had received 'moderate wake turbulence' from the preceding departure. I asked the pilot to file a report on this event. The north departure controller had a wake turbulence report on navajo position just a few minutes before this. This happens every day as phx tower uses 6;000/airborne and visual separation on every departure whether they are busy or not. I've filed several wake turbulence reports and I am actively trying to get my fellow controllers to report this every time. This is an unsafe procedure at phx and a smaller aircraft is eventually going to have an accident due to wake turbulence at a low altitude. Stop visual departures on large aircraft.

Title: P50 Controller voiced concern regarding the Tower wake separation techniques used with subsequent departures claiming the procedure is unsafe and results in wake turbulence encounters.
