Graham site team recently reviewed their method of dealing with and implementing dust suppression on-site at Varley Halls student accommodation in Brighton.

The review covered the following items:

  • Water usage – how the site team could reduce the litres of water being used onsite to suppress dust from chalk;
  • Labour cost and man hours mounting up;
  • Environmental cost using a natural resource although metered;
  • Dust pollution on-site and the affect it has on our neighbours;
  • Control measures to reduce water usage where implemented.

The site team purchased several water sprinklers and water piping that was installed around the site in strategic locations. These locations were identified as having large areas of dust build-up from the chalk, including the background areas that are not forming part of the construction site.

Once installed we monitored the system during the hot weather, this included recording the meter readings and comparing them to previous records. The dust suppression sprinkler system installed paid off and we recorded the following for site records:

  • Major reduction in litres of water used during dust suppression;
  • Man hours and labour costs reduced by half;
  • The control measures and isolation valves installed meant the sprinkler system could be operated on-site in several different site locations with minimal water being used;
  • Each sprinkler head covered a radius between 15 to 20 metres, this was most effective on the haul and service roads including the chalk banks and lay down areas.
