Landfill sites

Details of open and closed landfill sites in West Sussex.

We monitor the operational landfill site of Brookhurst Wood, which is managed by a private landfill operator, as well as the 6 closed landfill sites we have responsibility for.

All of these licensed sites are operated under Waste Management Licences or Environmental Permits which are granted and monitored by the Environment Agency.

Closed landfill sites

We manage and maintain 6 closed landfill sites, which are monitored regularly for landfill gas and leachate (liquid which may harm the environment). In addition, surface and groundwaters are also sampled to ensure no contamination is present.

Closed sites are restored by turning them into green space such as woodland, parkland or farmland.

Baystone Farm - RH13 0NP

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, which discharges to the nearby Horsham sewage works. In the summer of 2004 a number of gas and groundwater-monitoring boreholes were installed outside the waste body. The site was also re-profiled to smooth out depressions caused by settlement.

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

Faygate - RH12 4SX

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

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

Following completion of the site, 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.

This gas system was extended in 2010, which added an additional 20 gas wells around the site perimeter, as well as a new flare. A series of 40 gas-monitoring boreholes are located outside the waste body to monitor any gas migration.

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

Pendean - GU29 0EW

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

The site has a landfill gas management system, replaced and upgraded in 2001, and has nine wells.

The landfill gas is extracted 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 was also re-profiled in the summer of 2007 to smooth out depression caused by settlement.

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.

Sompting - BN15 0ND

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 which consists of 20 wells extracting gas from the waste body which was installed in 2012, replacing the old system. A series of eight gas-monitoring boreholes are 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 agricultural use, intended to be used for the grazing of cattle or sheep, or cropping for hay. Hares and partridges have also been seen on these slopes.

Steyning - BN44 3YG

The exact date this site first received any waste is unknown, although the railway is known to have been closed and the rails removed in 1966.

It is believed to have stopped accepting waste in the late 1970s, and records indicate it accepted predominately 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.

Westhampnett - P018 0NX

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

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

The site has a passive gas system, using a collection of 53 vent stacks. A series of 54 gas monitoring boreholes have been installed around the perimeter of the site to monitor any gas migration.

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.

The site was re-profiled in 2006 and is now used for cropping hay by a tenant farmer. The site is also home to a large population of breeding pheasants, foxes and rabbits, as well as the local bird life.
