Mamilla is back with the Chilli Boys having previously worked with the team as both Technical Advisor and head coach.
He joins a technical team headed up by September, with Mabhuti Khenyeza serving as first assistant.
The experienced mentor most recently worked as Baroka head coach but resigned in September last year.
Chippa most recently defeated Magesi 4-1 in the league on Wednesday, with Mammila in attendance.
Following the appointment, September expressed his delight to have the influential Mamilla back at Chippa, who are currently in 11th place on the league standings with 18 points from 14 games.
The coach explained on FARPost: "We were coming to fetch him here in Polokwane because he is from this side and the plan was arranged before that.
"He could not sit on the bench against Polokwane City [on Saturday during their 0-1 defeat], but we were always communicating about what he could help us with.
"We are happy that he came back to give his advice, so he is going to play a big role, especially on the technical side and of course off the field, he is a good group manager. I think he will help us in terms of managing the team to get into good fluency, so it is good to have him back.”
Chippa are next in action against TS Galaxy on Saturday.
