When lodging your application, the following information must be supplied in order for Council to assess your application.

Manufacturer’s plans and specifications indicating septic tank and collection well(s) dimensions and capacities, plus the licensed plumber’s name, address, phone number and licence number.
An accurately drawn, detailed site plan drawn to scale and showing:
1. The position of the house.
2. Floor plans for the dwelling showing all bedrooms, study, rumpus room, etc.
3. The sanitary fittings of the house (including toilet(s), bathroom(s), kitchen and laundry wastewater disposal points) with internal and external drainage to wastewater tanks marked.
4. The position of the tanks, the draw-off pipe and the suction outlet at street level. Note that tanks must be located a minimum of 1.5m from the dwelling, driveway or any impervious surfaces.
5. The position of the tanker standing area located a minimum of 3 metres from the centre line of the road.
6. A contour plan from dwelling to draw-off pipe.

Please Note:

Failure to supply the above information may result in processing delays.
Delays in approval may occur if Council’s Environmental Compliance Team needs to assess the availability of adequate access and manoeuvrability of sullage tankers.
If the holding well is installed in a position lower than the pipe outlet, a pump must be installed. This pump must be capable of delivering a flow rate of 364 L / min at the outlet.
If the holding well is installed in a position higher than the pipe outlet, a gate valve must be installed at the draw off pipe.
In situations where the placement of the pump-out pipe is through another property, an easement must be created. This may require assistance from solicitors and must adhere to Council’s “Terms of Easement” conditions.
To determine the optimum capacity for both septic tanks and holding wells, contact the Environmental Compliance Team on 9847 6829 or compliance@hornsby.nsw.gov.au.
Council requires that all wastewater applications are prepared in accordance with recommendations in Environment & Health Protection Guidelines and Australian Standard 1547:2012.
