Larnach Castle Wastewater Scheme
On-site Wastewater
Project Description
Larnach Castle is an iconic tourist attraction located just outside Dunedin in the heart of the Otago Peninsula. During the summer season, Larnach Castle experiences particularly high patronage from cruise ships, leading to high wastewater flows. In order to meet these peak seasonal demands, an upgraded on-site wastewater treatment dispersal system was required.
Services Provided
Fluent Solutions was responsible for the upgrade of the on-site wastewater system at Larnach Castle. Using a “keep it simple” approach saw the design and installation of a simple (large), dual chamber septic tank followed by dosing effluent to three surface based effluent distribution fields.
Specific services included:
- Site investigation
- Soil sampling
- Current and future flow calculations
- Reporting and resource consenting
- Hydraulic dispersal design using dosing siphons
- Commissioning of the system
Challenges
Located on the Otago Peninsula, Larnach Castle and its beautiful gardens provide visitors with breath-taking views of the Otago Harbour. Fluent Solutions provided a fully functional, on-site wastewater system that blended into the site to ensure the experience offered by this very popular tourist attraction was not adversely affected.
