Location: Jellinbah, Bowen Basin, QLD
Client: Jellibah Coal
Specs: 1.5 gigalitres, 32 hectares
Premise Engineering was appointed by our client, Jellinbah Coal, to undertake design and construction supervision of a de-watering, ‘regulated structure’ dam for their Central Operations. This significant upgrade would mean the dam, west of Rockhampton, offered 1.5 gigalitres in capacity and spanned a total area of 32 hectares.
The Jellinbah Dam was constructed behind the existing high-wall. Our design brief was multifaceted, and needed to address:
- De-watering storage for the surrounding coal mine site
- Compliance issues relating to mine inspections and water licences
- Safeguards to protect existing mine site infrastructure in case of major rain
- Provisions for spillways, water release and metering in major rain events
Despite challenges, such as constructing the dam wall during Queensland’s wet season, Premise Engineering was able to design and deliver a successful project for our client. We are proud to have met such a rigorous brief, and to have completed the Jellinbah Dam upgrade on schedule.
