Domestic Wastewater Management Plan

Golden Plains Shire

RMCG was engaged by the Shire to prepare a domestic wastewater management plan (DWMP).

RMCG reviewed and analysed current information and existing data, undertook stakeholder engagement to determine current and/or projected concerns related to domestic wastewater in the Shire, analysed and critiqued previous risk assessment matrices and developed a suitable risk assessment matrix for the prioritisation of Domestic Wastewater Management actions in Golden Plains Shire, reviewed and prepared town profiles, assessed capability of existing lots within priority township areas as to their suitability for sustainable onsite land application of effluent and prepared a land capability assessment tool.

Information gathered from these activities fed into the completion of the DWMP that met the Shire’s objectives in terms of policies and strategies for managing domestic wastewater.
