A university campus means dozens of buildings — laboratories, dining halls, halls of residence and sports facilities. The estates team cannot hand-check every trap over each summer shutdown. Green Drain™ covers the whole network through one standardised procurement.
Irish universities and Technological Universities across Dublin, Cork, Galway, Limerick and the regions. Each campus runs its own estates team, its own fixes and its own local habits, which makes standardisation hard.
According to the Higher Education Authority (HEA), Ireland has ~250,000 students in higher education across the universities (TCD, UCD, UCC, NUI Galway, MU, UL, DCU) and the Technological University network. Each campus includes dozens of buildings — refectories, halls of residence, science blocks and sports facilities — many running seasonal summer operations and conference schedules.

Campus estates teams adopt the specification, and it is rolled out over three to five summers, priority buildings first.
The campus maps all buildings and estimates the number of drains by building type.
One building (e.g. a dormitory) — pilot installation, one-season evaluation.
Central procurement — ASSE 1072 specification, delivery within 3 years.
The technical service is installing them in each building during the summer work.
Irish university and IoT campuses — TCD, UCD, UCC, NUI Galway, University of Limerick, DCU, ATU, TUS, MTU and the technological university network — combine listed heritage buildings, post-2000 builds, student residences, refectories and sport / aquatic facilities. Standardisation across the campus portfolio means a mix of all sizes, but GD 2 dominates because most sanitary fittings run DN50.
Green Drain™ doesn't work alone — for maximum drain control it's combined with GD Uri-Tabs™ (urinals) and GreenSwirl™ (drain unblocking).
Patented silicone seal for halls of residence, colleges, dining halls and laboratories. ASSE 1072-2020 specification for public procurement and BIM documentation.
Bio-enzymatic urinal tablets for washrooms in faculty buildings and student housing. One standard across the whole campus and fewer service call-outs.
Biofilm cleaning in the sewer systems of dining halls, laboratories, and sports facilities. Chemically neutral, compatible with laboratory processes.
We come to the site, map the drains, and provide a written recommendation — no cost, no obligation.
