FAQs

What do I get for my money?

Council require the report to nominate one method of treatment and disposal, so we want to be sure you understand what it is we are proposing before we commit to this in the report. There will often be a few options available and we are happy to run through these with you.

The options we can discuss and prepare a report for includes:

  • Septic tanks and soil absorption beds/trench
  • Septic tank and sand mound
  • Septic tank and evapotranspiration bed
  • AWTS and spray or subsurface irrigation
  • AWTS and soil absorption bed, sand mound or evapotranspiration bed
  • Worm farm and trench/bed

Can you provide a report that lists different options?

Do you install or recommend installers?

We do not install but we may be able to suggest local suppliers and installers.

What happens if council request modifications, changes or reject the proposals completely?

If Council asks you for additional information, we will make the necessary changes. These changes may be the result of a change to the proposed development (location of buildings or number of bedrooms) or a change to the Councils assessment criteria. In most cases, the changes are minor and we deal with them immediately.

I have an 88B on my property, can this be changed?

An 88b may require a specific method of wastewater treatment and disposal. We will need to be given all relevant documentation to understand what is required and whether this can be changed.

I want to build a shed now to live in while I build a house. Do I need a report?

Yes. Where relevant, we may suggest that the wastewater treatment and disposal system is sized in accordance with the size of the house you plan to build so you may not need to get another report.

We are adding an extra bedroom, but there won’t be any additional people living in the house, do I need a wastewater report?

Yes. The size of the wastewater disposal area (irrigation area or soil absorption bed) is based on the amount of wastewater generated from the house, which is determined by the number of bedrooms and whether the house has town or tank water supply.

Why do I need to install such a large wastewater disposal area compared to my neighbours who have the same sized house and block?

The reason for this may be the size of the house. The size of the wastewater disposal area is sized on the number of bedrooms and water supply (town or tank water). A 3 bedroom house will have a wastewater disposal area half the size of a 6 bedroom house.

It may also be because the house with the smaller wastewater disposal area is older and installed prior to the current rules and regulations.

I am planning a subdivision. Do I need a report?

A report is required to demonstrate that the proposed lot can support residential development with on site wastewater management. The report must show the nominated house site is compliant with the relevant Council DCP and State Government guidelines. The report can nominate a specific wastewater disposal area or a larger Effluent Management Area to provide future owners with greater flexibility.

What other types of development do you need a report for?

We have prepared reports for child care centres, boarding houses, restaurants and function centres, industrial work sites, service stations, horse stables, dog boarding kennels, chicken abattoirs, etc.

How much does a report cost?

We provide a quote after we discuss the job over the phone. If you provide us with the site address and Lot/DP, we can look up the aerial photograph while we talk. In most cases, a report for a standard residential dwelling will cost around $1100 to $1200.

My property is within the Sydney Water Catchment. What sort of report do I need for Sydney Catchment Authority approval?

The On site Wastewater Assessment prepared for a property within the Sydney Water Catchment is also known as a Water Cycle Management Study or System Design. The SCA have published their own assessment guidelines that require greater depth of assessment and design than a standard report. The cost to prepare one of these reports will be more than the standard report.
