Harrow Council has introduced a booking system at the town down in a bid to avoid long queues.
From Monday, June 29, residents can only dispose of rubbish at the recycling centre in Forward Drive if they have booked a slot.
The council said the new system has been introduced to prevent long waiting times and queues into the facility, which were affecting nearby homes and businesses.
It is open to Harrow residents only who must bring a valid ID and their booking confirmation with them.
Anyone who arrives without an appointment will be turned away, the council has warned.
As well as booking a slot, those wishing to offload junk at the dump have been told to sort their waste before they arrive.
Only six spaces will be available at any one time to enable social distancing.
You can book your slots online here.
