The North London Waste Authority (NLWA) wished to commission an independent and experienced consultancy to carry out surveying at each of the nine Household Waste and Recycling Centres (HWRC) across North London.
At the time, operating costs for the sites were borne by the host borough, but there were plans in place to divide the cost according to the same proportion as the home origin of the visitors to each site in the future.
In order to fairly apportion the operating costs, it was necessary to determine the origin of visitors to each site across the London Boroughs of Barnet, Camden, Enfield, Hackney, Haringey, Islington and Waltham Forest with a high degree of confidence.
Enventure Research was appointed to undertake the survey of HWRC visitors. The main objective of the survey was to collect postcodes from all visitors delivering waste to each of the nine HWRCs in North London for the property where the waste was produced, accurately recording the date and time of visits.
A team of six experienced surveyors were recruited from the local and surrounding areas. The team attended a comprehensive training session designed to educate them in surveying techniques, the HWRCs across North London, the questionnaire layout, the use of surveying equipment and important health and safety issues, including the site risk assessments and identifying where best to stand whilst surveying at each site.
A surveying schedule was devised to ensure that two staff would be present at each HWRC on specified dates for the full operating day. Surveying was undertaken on both weekends and weekdays in order to get an accurate sample of usage.
Handheld tablet computers were used to record the residents’ postcode (or alternatively their street and Borough) and date and time of their visit. The number of visitors who refused to take part in the survey was also recorded. The data was uploaded on a daily basis to Enventure Research, which allowed for real-time data analysis, performance checks of the team and progress updates to be carried out daily.
Results and Benefits to the Client
During the survey, over 19,000 postcodes were collected across the nine sites.
Upon fieldwork completion, Enventure Research delivered the findings to NLWA, showing postcode data collected from each HWRC with a breakdown of numbers and percentages of users from each Borough.
The results will be used to help fairly divide the cost of running the HWRC sites between the Boroughs.
