Enquiries

Kangaroo Island Council (the Council) invites tenders from suitably qualified and experienced

Tenderers for the provision of Plant and Labour for construction of Wastewater Treatment Plant at

Penneshaw. The Council will enter into a Contract for Services with the successful Tenderer.

There are currently in the order of 235 existing houses in the township of Penneshaw, including the

Seafront Hotel, Penneshaw Hotel, Backpackers and Youth Hostels and the newly redeveloped

Caravan Park. The ultimate development within the township boundary specified by Council is

approximately 435 allotments. Currently wastewater treatment from the existing houses is achieved

by on-site treatment via septic tanks or aerobic systems and discharge to soakage trenches or

irrigation. Council proposes constructing a full sewage collection scheme with connections provided to

each property within the scheme limits. Sewage will be collected by a combination of gravity drains

and rising main and discharged to the treatment plant site, some 3 kilometres south east of the town.

Construction of the collection network being full sewer is expected to be completed in stages in order

to service fully developed parts of the township initially and expanded as the township develops.

Treated wastewater will be stored in the lagoon at the WWTP site. Class B effluent, as outlined in the

SA Reclaimed Water Guidelines shall be achieved. Filtration and disinfection is to be undertaken after

the lagoons and recycled water will be used for irrigation.

The treatment requirement is to achieve a mean value BOD

not greater than 20 mg/L and a mean

value of suspended solids not greater than 30 mg/L. A median termotolerant coliform (E coli) prior to

irrigation shall be not greater than 100/100 mL.
