Narrative: Aircraft X checked onto our frequency at and needed a weather deviation; however we couldn't understand him right away. There were 2 lines of weather precipitation depicted on the scope; both lines parallel; one running from about PTW to the southeast to ACY; and the other running from about EMI to the southeast to GARED. The winds were out of the south about 50-80 miles; pushing the lines north. We had EWR arrivals running over JAIKE..ILENE..KEWR because they couldn't stay on the PHLBO arrival up to ARD. Eventually; this path closed up and now the EWR and EWR Satellite arrivals couldn't stay over ILENE or JAIKE; and were not staying in PHL North High's airspace any longer. The sector team decided to stop running all EWR's and EWR Sat's over JAIKE and we shut off sector 12. Departures over RBV were already shut off; and LGA arrivals were routed over SIE. Traffic Management Unit (TMU) coordinated J220 routing for some Satellite arrival aircraft. I am not sure what happened; but then TMU called and said that ZNY was going to take 2 more EWR's over the JAIKE routing (which they could not stay on anyways); but that they wanted us to run over PEEDS; then turn northbound to give to Modena in Modena's altitudes. At this time; the weather on the big board in the area showed a patch of red weather; and our scope had extreme precipitation. We knew tops were in the low to mid 300's from previous reports. The first aircraft that was doing this new 'TMU' plan was Aircraft X; which came from sector 12 descending to FL240. When the aircraft was near PEEDS; they reported the severe turbulence.There were 2 lines of storms that were staying strong and persistent moving northeast bound. Weather unit was predicting moderate to severe turbulence throughout the day. We needed to have the aircraft moved around this system a lot sooner than it was. I later found out an aircraft flying through Pinion [sector] reported severe turbulence around AML at 28000 feet then as the same system moved Northeast bound where the Aircraft X had the severe turbulence over PEEDS. At the sector; we had shut off this traffic going over JAIKE; but TMU called and said they coordinated to have 2 EWR go back over it; even knowing about the severe turbulence previously reported. Area 4 said PHL's were being re-routed into the severe turbulence earlier in the day and early evening; and IAD arrivals were getting severe turbulence earlier on the CAVLR3 arrival.We are used to the chaos and not planning from TMU/Command Center and our management teams not supporting the operation in an appropriate way because we have continuously been dealing with this at Washington Center every Thunderstorm season every year since as long as I've been here. We are used to it; we are sick of it; but we do it every day in the name of safety to the best of our ability. However; when aircraft are purposely routed into known severe turbulence that is negligent and completely unacceptable. Severe turbulence causes injuries and can lead to death. This is the line I am not willing to cross; this is enough. This needs to be fixed from the top down. This is bigger than just Washington Center; and there is complete degradation of safety culture that is in existence in the system right now. Why can't we be better? Controllers are at a loss; nothing seems to help; so we put up with it day in and day out; but nothing changes.




Synopsis: A Controller reported that the Traffic Management Unit routed aircraft through areas of known severe turbulence.
