Optimising Demand Reduction in Water Utilities

10 pagesPublished: September 20, 2018


Effective water resource planning is an important part of long term strategy for any water company. A good water resource plan will ensure a long-term balance between supply and demand. In this paper we present a scalable, repeatable and transparent model for finding efficient demand reduction solutions given a large number of demand reducing options and small planning regions. This model is being developed for application in UK water utilities for demand side water resource planning to aid results presented to Ofwat, the UK Water regulator, as part of multi-billion-pound long term investment plans. The flexibility and granularity of the approach has been shown to offer significant cost savings while still allowing a utility company to meet customer and stakeholder targets and Ofwat regulatory requirements.
