University Hospital Llandough

Welsh Health Board future-proofs Hospital development


University Hospital Llandough is one of nine hospitals operated by Cardiff and Vale University Health Board, one of the largest NHS organisations in Wales. Located in Penarth, 5 miles from the centre of Cardiff, Llandough has approximately 500 beds and runs a number of Day Hospital specialist clinics. The MHU project includes an 82 bed mental health hospital for older in-patients, a 40 place day hospital and an Assessment & Recovery Centre for 35 people.


Commissioned by Laing O’Rourke (Expanded Group) on behalf of Cardiff & Vale University Health Board our brief was to incorporate a sustainable drainage system for the Hospital’s new Mental Health Unit Car Park.


As part of an overall objective to support improved patient recovery and reduce the number of residents being cared for out of area, the main purpose of this project is to centralise all general adult mental health inpatient services for Cardiff and the Vale of Glamorgan at Llandough Hospital and to accommodate older patients being transferred to Llandough from Whitchurch, Barry and St David’s Hospitals.


As part of the circa £57 million project, construction of a 135 bed specialist mental health care unit, supported by sufficient car parking facilities, took place between September 2012 and Spring 2013.


How it works

Although not specified on the original drawings, SDS demonstrated how it could make significant improvements to the proposed designs and deliver a stronger package of benefits to the end customer.


As a result, 2 GEOlight® tanks were manufactured and installed with a total combined capacity of 2,401m3.


Ready access to the site was restricted by the high numbers of staff, visitors and outpatients at the hospital throughout the day along with the associated volume of traffic movements. Nevertheless, SDS was able to complete the project to its customary high standards ahead of schedule and without interference to the hospital’s busy 24/7 operation.

University Hospital Llandough

University Hospital Llandough provides a constantly evolving range of health and wellbeing services to the half million people living in Cardiff and the Vale of Glamorgan, who represent 6.6% of the population of Wales.

What our other Customers say

GEOlight® geocellular storage from SDS was the obvious choice for the water management solution designed by Ulrich Groenewald of the engineering project team from AECOM, in coordination with SDS. We were able to work with the architect to deliver a drainage design that satisfied regulations and reflected our analysis of what rainfall we might expect.
