On-Site Effluent Report

10.0    DEFINITIONS

Design Loading Rate (DLR)
The long term acceptance rate (LTAR), reduced by a factor of safety, expressed in L/m2/day or mm/day as applied
to the horizontal design area of a land application system.
Design Irrigation Rate (DIR)
The loading rate that applies to the irrigation of a land application area with effluent of a secondary quality. It is
expressed in L/m2/day or mm/week. If a spray irrigation system is used, the secondary effluent is subject to
continuous disinfection.
Durable Aggregate
An aggregate with the grading requirements specified in AS 2758.1 for single-size course aggregate for nominal
sizes from 20mm - 40mm.
Geotextile
Any permeable durable synthetic textile material used with foundations, soil, rock, earth or other geotechnical
engineering related material.
Land Application Area
The designated area of land and reticulation system used for the disposal of the treated effluent.
LTAR
The long term average rate an effluent can be adsorbed into the soil of a disposal system, expressed in litres per
square meter per day. LTAR is dependant on effluent quality, permeability and organic loading.
Permeability
The rate clean water is transmitted through a soil, expressed in meters per day.
Water Reduction Fixtures
Fixtures include 11/5.5 litre water closets, shower flow restrictors, aerator taps and water conserving washing
machines.


11.0    REPORT LIMITATIONS

The log sections in this report should be representative of the soil conditions over this site, however, soil conditions
can change dramatically over short distances. The person responsible for installing the system must observe the
soil profile and ensure it matches the soil profiles recorded in this report. If soil conditions differ from those recorded
by us, we must be immediately notified so that further investigation can be carried out and the system design
modified if necessary. This work may involve additional fees and costs. This company will not accept any
responsibility for additional costs to any party as a result of soil variations.

In writing this report, we have also considered all the information supplied to us by our client. Should the client or
his agent have omitted to supply us with relevant information, our report may be irrelevant and/or inappropriate.
We do not take responsibility for the consequences in such cases and we will make an additional charge if as a
result, more testing or rewriting of this report is necessary.

The operation of the disposal system is dependant upon the hydraulic load, the type of the material entering the
system and the maintenance of the system. As these factors are beyond the control of this company we do not
take any responsibility for the long term adequacy of any disposal system constructed on this site or the
consequences of its malfunction.
