Challenges of design and construction for reservoir safety improvements within an historic estate

Detailed design and construction of any reservoir safety and improvement works can be challenging. The team successfully overcame the constraints of three historic dams with protected ecology all set within a National Park and a Grade 1 listed parkland with a remote moorland access.

The chosen solution provides compliance for the two high risk dams and peace of mind for the third within a limited budget for the charitable owner. The works included new top water level and auxiliary weirs with associated spillways to three reservoirs and crest raising on two high risk (Category A) dams.
