Kensworth Quarry Chalk Pit Site Restoration |
Project summary
Kensworth Quarry is the UK's largest chalk pit and is one of the largest in the world. It is located to the top of the Chilterns ridge close to the head valleys of the River Ver which has suffered from unsustainable water abstraction to support local development.
Production from the quarry is due to cease within the next decade after which it will be subject to a site restoration program.
It is proposed that as part of the site restoration plan consideration be given to establishing a permanent perched reservoir as the focus of wetland nature reserve and 'geopark' of international significance. The reservoir would also be used to provide head water support to the Eiver Ver during extented dry periods. In addition the perched reservoir could be used to as a pumped hydro energy storage facility to support the growing network of solar energy plants in the farmlands west of the Chilterns ridge.
Monitoring surveys and results
The project is on the early evaluation stage focusing on stakeholder outreach, regional planning advice and technical advice in hydrological assessment and pumped hydro storage assessment.
Preliminary work suggests a short pipe line connection from the perched reservoir to the source of the River Ver could provide 3000 litres per second of flow support to the river for up to 30 days.
