Problems and suggestions

Can anyone enlighten me as to the whereabouts of 'West Bedfont'? According to the A to Z it is an ESSO Oil Terminal! There is a Constructed Wetland (BAA Property) which may be interesting but it is not open to the public. There have been several interesting reports on this web site from this area and I am sure others, like me, would be interested in a precise location. Hope someone can help. Thanks, Paul
