Project Details
Scope of Work
- The main dam is 650m long and 15m high covering 6.5 ha.
- The wall is a zoned envelope containing 300,000 m3 of material.
Significant Achievements
- The natural material was variable in quality and was often found to contain excessive moisture making it very difficult to manage.
- The work adjoined a major public road and although this provided constant public scrutiny of the site there were no complaints or adverse comments made about Daracon’s performance.
- The concrete spillway and terraced gabion walls is an attractive feature of the design and can be easily seen from Denman Road.
- The site was protected from flooding before dam construction commenced by installing a series of diversion banks and drains. This also helped to keep the poorer material as dry as possible.
