Earth dam design – National Botanic Gardens, Wales

Location: Carmathernshire
Sector: Public
Client: National Botanic Gardens

The National Botanic Gardens project to restore the 18th century landscape at their centre near Carmarthen included the reconstruction of a earthwork dam.  This works is nearing completion thanks to the ground investigation and design work undertaken by GOWN Engineers.

GOWN designed the ground investigation to enable the design of the dam then undertook the design of the dam in terms of its permeability and stability.  We went on to provide construction advice for the earthworks.

The gardens are a great place to visit, we hope you enjoy seeing the newly restored lakes in 2019.

Dams are far from glamourous – slurry lagoon

Location: Pembrokeshire
Sector: Agricultural
Client: Large dairy farm

Agricultural civil engineering on a significant scale can mean big sheds/barns, new roads but often means providing slurry storage.  In a recent project GOWN Engineers design the remediation of a large earth bunded lagoon which had leaked contaminating a local river.

The volume of this lagoon was some 20,000 cubic meters.  The leak was much smaller than the total but did mean the stability of the lagoon’s bund needed addressing.  GOWN designed a earthworks solution that minimised the work required to stabilise the bund, we also specified a cut-off and monitoring drainage such that the effectiveness of the works could be confirmed.

The reuse of on-site materials meant that the project was completed as sustainably as possible.
