Closed landfill sites

The site is believed to have opened in the early 1960s, stopped accepting waste in 1981 and was fully restored by 1986.

The site contains a leachate collection system. This discharges to the nearby Horsham sewage works. The site has a number of gas and groundwater-monitoring boreholes which are installed outside the waste body. 

The site is now used for cropping of hay and is home to local deer, rabbits and foxes.

This site is mainly surrounded by agricultural land. It is believed to have opened in 1967. Crawley Borough Council initially operated the site and West Sussex County Council took this over.

The site stopped accepting waste in June 1993 and was fully restored by 1996.

Following completion, a landfill gas management system was installed, consisting of 33 gas wells. These extract landfill gas from the waste body which is then flared off.

We extended the gas system in 2010, adding an additional 20 gas wells around the site perimeter and a new flare. Outside the waste body there are 40 gas-monitoring boreholes to check for gas migration.

The site is now used for hay cropping. It harbours a wide variety of wildlife ranging from a large wild deer population to woodpeckers, skylarks and other flora and fauna.

This site is believed to have opened in the 1960s and stopped accepting waste between 1974 and 1976.

It has a landfill gas management system, replaced and upgraded in 2001, and has 9 wells.

We extract the landfill gas from the waste body and then discharged via a gas flare. A series of 4 gas-monitoring boreholes are located outside the waste body, between the site boundary and the neighbouring properties in Pine Close. They consist of boreholes drilled to 3 different depths of 12m, 7m and 3m. 

The site is fairly isolated and occasionally used to graze horses. It is home to breeding woodpeckers and a large population of rabbits and pheasants.

This landfill site partially in-fills a dry valley. It is believed to have opened in the 1940s and closed in the 1990s, being restored by 1993.

The site has a landfill gas management system consisting of 20 wells extracting gas from the waste body. We installed this to replace the old system in 2012. There are 8 gas-monitoring boreholes located along the eastern edge of the site, along the access road, and 12 around the perimeter of the landfill.

The site was restored for the grazing of cattle or sheep, or cropping for hay. Hares and partridges have also been seen on these slopes.

We do not know the exact date this site first received waste, although the railway closed and the rails were removed in 1966.

It is believed to have stopped accepting waste in the late 1970s and records indicate it mainly accepted domestic waste. A leachate collection system was installed along the southern side of part of the site in the early 1980s. The leachate is collected and pumped to the adjacent sewage works for treatment.

A series of monitoring boreholes were installed in 2012 to monitor landfill gas, leachate and groundwater within the landfill site.

The site is fairly isolated and is used for grazing horses and cattle.

This site in-fills a former gravel working It was opened in 1970, operated by Chichester District Council.

It stopped accepting waste in 1983, but was re-opened between 1988 and 1991. It was finally restored in 1995 using material excavated from the A27 Westhampnett by-pass.

In autumn 2003, a groundwater treatment plant was constructed, located on the other side of the A27. This manages any contaminated groundwater produced by the landfill site. The on-site treatment plant aerates the collected liquid, which then passes through a reed bed system. This is then discharged into the flooded gravel pit operated under a discharge consent from the Environment Agency.

We installed a series of 54 gas monitoring boreholes around the perimeter of the site to monitor any gas migration. We also installed a new gas extraction system was in 2017. A series of gas wells dispose of gas via a gas flare to prevent any gas migrating off site.

The site now hosts a solar farm, installed by the county council in 2017-2018. It generates 7.4 megawatt of electricity - enough clean energy to power 2,400 homes. More information on the scheme can be found on our Westhampnett Solar Farm page.
