A second fire in a week broke out on Monday evening in Westhampnett when the tip caught fire.
Road closures were put in place last week when on Tuesday night (February 25) a fire broke out at an industrial building in Stane Street.
This week, on Monday evening, at around 6pm, the fire service was alerted to a blaze at Westhampnett household waste and recycling site along the same road.
A spokesman for West Sussex Fire and Rescue Service said: “Joint Fire Control sent four fire engines in response to the original 999 call, with two from Chichester Fire Station, one from Bognor Regis and one from Selsey attending.
“The two crews from Chichester Fire Station were first on the scene and found around 200 tonnes of general household waste alight. Firefighters worked quickly to stabilise the fire and managed to save a number of nearby lorries and items of heavy plant from fire.
“The fire and rescue service has been supported by the county council waste services and the resilience and emergencies team.
“Crews remained at the site throughout the night, with a relief crew taking over earlier this morning at the site. They have been spreading the fire across the concrete yard so it burns away quicker.
“The fire is now much reduced in size with a small amount of smoke visible in the near area. This may cause a smell locally but presents no risk to health. But we advise residents to keep their doors and windows closed to avoid any smell or inconvenience.
“The cause of the fire remains under investigation at this stage.”
A blaze broke out in the main building at the centre involving more than 500 tonnes of household waste on April 2, 2019, and was not extinguished until a week later.
Back then, the area where green waste was deposited was unaffected by the fire, enabling Viridor to re-open just this part of the site.
A spokesman said they anticipate the tip would re-open tomorrow (Saturday).
