Water

Overview

  • 1,170 homes were supplied with garden rainwater harvesting (2016: 1,183)
  • 198 active sites had Sustainable Drainage Systems (SuDS) designed into the development (2016: 129)
  • 91.3% of new sites were fitted with construction use water meters

Performance Against 2016/17 Target

We will introduce metered supplies for construction water usage at 90% of new developments, building up an accurate picture of Bellway’s water usage

91.3% of new sites were fitted with water meters. Construction water usage will continue to be monitored and analysed, with usage trends identified based on differing site characteristics. Reduction initiatives will then be tailored to different site types and construction methods

2017/18 targets

For the 2017/18 Bellway financial year, we have set a range of targets across our three CR themes (Environment, Construction, and Society and Economy). We have prioritised these targets and published our top 12 priorities across the themes for this financial year. This approach allows us to focus our efforts on the areas of greatest impact, while continuing to work internally on our additional targets.

Although we do not have a publicly published target for water this financial year, we are very much committed to the ongoing enhancement of this area of our business and will continue to pursue our non-published internal targets.

Flood Mitigation

When a new site is identified, we assess the potential environmental impacts of the development, including the consequences for the water cycle. The risk of flooding is considered at all stages of a project, from initial design through to construction. Flood risk assessments and surveys are carried out and drainage experts are involved in site master planning. Each construction phase is planned with a view to protecting sites and their neighbours before other works begin.

Where we create new hard-standing areas, such as roads and foundations, in areas which were naturally porous, we take measures to reduce the level of run-off water. We support the use of porous paving and creating water drainage systems such as Sustainable Drainage Systems (SuDS). SuDS are drainage solutions that provide an alternative to the direct channelling of surface water through networks of pipes and sewers to nearby watercourses. By mimicking natural drainage systems, SuDS aim to reduce surface water flooding (by increasing water storage capacity), improve water quality and reduce the transfer of pollution to the water environment.

Domestic Water Use

To aid our customers in their water use reduction, all Bellway new homes incorporate reduced water use measures. Some of these measures include dual flush lavatories which use one third less water, low overflow devices on baths, kitchen tap flow reduction devices and aerating water in showers. In some cases we incorporate water efficient considerations into the design, such as the use of grey water recycling (water diverted from sinks into the lavatory cisterns) to flush lavatories. We also supply some homes with rainwater recycling butts, helping to reduce customers’ needs to use hosepipes in the summer months.

As part of the requirement of building regulations, with these technologies in place we have reduced the average water consumption in our homes from 150 litres to a maximum of 125 litres per person, per day. This provides financial savings for our customers as well as ongoing wider environmental benefits. Through the ongoing roll-out of our Standard House Types we aim to reduce this further.
