EFFLUENT IRRIGATION MANAGEMENT PLAN - STAGE 1 )
NOOSA NORTH SHORE ECO-TOURISM PORTAL C Cardno

It is proposed to irrigate the areas only during non-rainfall days, with irrigation only
sufficient to wet the soil to its undrained upper limit. Automatic irrigation scheduling
equipment with soil-moisture probes and rain sensors will be necessary for control of
the irrigation. Irrigation will only re-commence a minimum of 4 hours following
cessation of rainfall.

 

3.3 Groundwater and Surface Water Quality

During effluent treatment and disposal, monitoring of groundwater quality will be
undertaken annually as specified by the conditions of the preliminary development
approval. Quarterly baseline monitoring of groundwater quality has been underway
since December 2004 to determine current groundwater conditions. In accordance with
the conditions of the development approval, quarterly baseline monitoring of receiving
waters including groundwater and surface waters will be conducted for a minimum of
12 months prior to commencement of construction works for the proposed
development and will continue during construction and for 2 years after completion of
construction works.

Groundwater monitoring will include analysis of pH, Electrical conductivity, Total
dissolved solids, Biochemical Oxygen Demand, Sodium, Salinity, Chloride, Sulfate,
Alkalinity, Nitrate and Nitrite, Ammonia, Total Nitrogen, Total Phosphorous and Faecal
coliforms. The quality of surface water runoff from irrigation areas will be monitored
where there is a minimum of 30 mm rainfall in the preceding 24 hours sufficient to
cause runoff from the irrigation area. Surface water monitoring will include two event
samples of runoff from the irrigation areas collected annually, and analysed for pH,
Total Nitrogen, Total Phosphorus, Electrical Conductivity, and Faecal Coliforms.

The discharge limits contained in the Development Code may be amended in
consultation with the Environmental Protection Agency and Noosa Council following
determination of existing water quality conditions through baseline monitoring. No
criteria have been specified for groundwater quality, therefore it is proposed that criteria
be defined following the completion of baseline monitoring which commenced in
December 2004. Locations for water quality monitoring are presented on Figure 2.
