Here at Robertson, we are continually trying to improve. At one of our projects in Huntershill, Bishopbriggs, the 2 graduate Site Managers were tasked to design and build a method to harvest rainwater.
The graduate Site Managers had the use of two apprentices TIGERS (Training Initiatives Generating Effective Results Scotland) which gave them valuable experience and training on how to operate small hand tools and more importantly to consider health and safety.
The graduate Site Managers, came up with the idea of adding a gradient to the previously flat roof of the a site cabin, simply by fixing sheets of ply to the roof at a gradient of 13 degrees, on top of the ply sheets of membrane were fixed and were draped into a guttering system fixed to the side of the cabin, this then ran the water into a downpipe and into water tanks at the back of the cabin.
This water is now used on site for flushing toilets, washing hands, and cleaning boots, and is recorded on a weekly basis to show how much rain water has been harvested.
Not only does this have a positive effect on the environment but it also keeps the Quantity Surveyor happy as we have almost halved the number of water deliveries per month.
Further more, since completing the system we have been in contact with Wernick Hire who have since advised us that they will look into a method of offering cabins with a RWH system built in place.
