When using a waste water treatment system the re-use of the effluent - the treated, recycled water, is critical. Effluent disposal areas commonly know as Land Application Areas (LAA) must comply with your local council regulations and the design is dependent on many factors, including site conditions and soil types.
We have extensive experience in the design and installation of effluent disposal areas that comply with state and council regulations.
Contact us for a complete Site and Soil Evaluator’s Report for the design and installation of your effluent disposal area. To help you plan your system, we have the most common types of installations listed below.
Dispersal of the treated effluent is usually
via a lilac poly pipe (lilac pipes are used to indicate
recycled water) buried from the tank to a defined
effluent area, where stand posts or turf valves are
Attached to the post or turf valves are lilac
sullage line/lines with low droplet, heavy sprinkler heads.
Dispersal of effluent is via a lilac effluent line into a garden area with evenly spaced drippers placed in the line.
The lines have approximately 10cm of mulch or other cover over the top.
Dispersal of effluent is widely used and can cover a large area with even
Again the line is lilac in colour and has
uniformly spaced pressure compensated drippers / emitters placed into the line.
Dispersal of effluent can be via gravity from a septic system of pumped into the end of the slotted pipe, buried in a trench.
Common on sloping ground when good soil is available.
Dispersal of effluent can be completed in many ways.
The most popular is the use of socked aggregate line with pipe placed inside with evenly spaced 4mm holes.
