Mapping & Condition Assessment of the Sewer System

Background

The Falls Creek Alpine Resort Management Board is responsible for the management, development and promotion of the Falls Creek Alpine Resort.

The Falls Creek sewer system has been progressively developed since the resort was established in the 1950’s and existing documents regarding the location and extents of the system are incomplete and have been poorly maintained.

Objectives

The main requirements of the project were to:

RapidMap was responsible for delivery of item 1 above, while our project partner, Veolia Water Network Services, delivered the services required to complete items 2 and 3. (The network condition assessment was carried out using CCTV).

Falls Creek Sewer System

The sewer system consists of approximately 3km of PVC mains and over 150 concrete manholes. The system is predominantly gravity based at terminates on site at treatment facility. The majority of the system is constructed of 150mm PVC with a short section of 200mm PVC prior to the inflow of the treatment plant. At the top end of the system there are also several short runs of 100mm PVC connecting the uppermost sites in the village.

At this time there is known to be several manholes that have been covered under roadways and possibly in other areas.

Project

The project included mapping the location of all sewer mains within the Resort including the dimensions of pipes, pits, junctions, in-flow pipes, out-flow pipes and other infrastructure, assessing the condition of the sewer infrastructure, and developing a sewer mains maintenance and replacement schedule.

Detailed information collected included:

Many sewer related assets could only be located after extensive searching, the final dataset included full details of many manholes that had been covered over for many years.

Deliverables

The project deliverables included the following outputs to FCRM:
