As climate change continues to take hold, extreme weather conditions are becoming more common. The United Nations predicts that over four billion people will be affected by severe water shortages by 2050.
While the average person in England and Wales uses about 150 litres of water daily in the home, this is only the tip of the iceberg.
Waterwise has estimated that the average person consumes over 3,400 litres every day, taking into account the water which has gone into making the products we consume, from the car we drive to the food on our plate. This includes water use along the supply chain both in the UK and overseas.
In order to produce just one kilo of beef it can take the use of up to 16,000 litres of water, whilst 1,000 litres of water can produce just one litre of milk. When considering these are small readily available products it is on a much greater scale the effects of construction must be measured upon.
There are a number of ways in which we can reduce water usage in the course of our operations. We can reduce the amount of water we use during the construction process. We can influence the market by choosing materials manufactured using less water. We can design our buildings so that they need to use less water when occupied.
Reducing Water From Our Operations
Willmott Dixon is committed to reducing the amount of water we consume across all construction sites and site offices, by introducing more efficient processes and technologies.
All water usage associated with our operations in measured as an Environmental Key Performance Indicator (eKPI). All our sites record data for the following eKPIs:
· Electricity (kWh / £100k)
· Gas (kWh / £100k)
· Waste (m3 / £100k)
· Water (m3 / £100k)
· Biodiversity (Client rated)
Recognising that as our business grows we will inevitably consume more water, we aim to reduce water consumption by 5% year on year over 2012 baseline.
Here are some of the ways we are reducing water consumption on our projects:
1. We install water meters as soon as we arrive on site.
2. Utilise early opportunity to install and connect environmental infrastructure on the site for later applications e.g. dust suppression and wheel wash
3. We maximise water efficiency within site offices by using aerated taps, flow control and waterless urinals
4. We display environmental performance figures in prominent places on site
We have continued to reduce water consumption related to our activities, and in 2012 our water consumption per £100,000 of turnover fell 4% from 10.0m3 to 9.6m3
Water Efficient Homes
Willmott Dixon is committed to the delivery of water efficient homes as part of its 10 Point Project Criteria. Under the 10 Point Plan our aim is to deliver Code for Sustainable Homes Level 4 across all homes we build.
Our target is to design and build homes that consume fewer than 105 litres of water internally per person per day. We engage our clients early in the project design process, to understand their project sustainability aspirations and requirements. Then we propose a range of cost-effective measures which meet both the clients’ and our 10 Point Plan requirements.
