Sponsored data integration and expression project with Northumbrian Water – Get involved
#Hack Series 2017-2018 Event 2:
Northumbrian Water Group (NWG), which includes Essex & Suffolk Water in the South East and Northumbrian Water in the North East of England. We pride ourselves on offering excellent product and service and go to great lengths to ensure our product tastes great and smells good. Needless to say we are keen to ensure our customers are happy with our product 100% of the time.
Very rarely we receive a complaint about a change in taste and odour (far less than 1% of customers contact us about this issue). The events are few and far between but across our 2.7 million customers and 5 years of data there are sufficient to explore the root causes.
To make this more challenging, as well as a low density and geographically distributed nature of recorded events, the range of factors that can lead to a perceived change in taste and odour sufficient to contact us are diverse.
- Water blending processes
- Changes to water sources
- Local distribution works
- Repair/ replace/ maintenance works
- Water processing decisions
- Debris entering local supply
- Domestic pipework issues
- Property age and type
- Chlorine residual effects
- Changes in supply temperature
- Social dynamics
- House moves/ customer relocation
