what is a WASTEWATER MANAGEMENT REPORT?
A Wastewater Management Report is fundamentally a technical document, produced by a Broadcrest Engineer, which determines how the sewage produced on-site will be managed, treated, and then disposed. This process, known as On-site Sewage Management (OSSM), is a fundamental design consideration for any site that does not have reliable access to mains sewage services. A Broadcrest produced Wastewater Management Report carefully considers the management options for your on-site Wastewater; whilst also recommending measures to ensure the long-term protection of both public and environmental health.
WHEN DO I NEED A WASTEWATER MANAGEMENT REPORT?
On-site Sewage Management (OSSM) is commonly one of the last considered components of a development; as unless you work in the Industry or are a licensed plumber, it's seldom considered where everything goes once a toilet is flushed. For new builds, requiring a Wastewater Management Plan / report will likely be indicated by way of council correspondence, or from advice of your planner / builder during the DA process.
For existing residences and commercial premises, a Wastewater report is often required after a local government inspection of your system, and where there are indications the wastewater system is either faulty or outside its design life. In the latter case it may not be cost-effective, or practical, to replace the failing system like-for-like; over time government requirements become more stringent, and certain technologies become more affordable since your original systems' installation.
Whether a new or existing site, if you:
- are unsure if you have access to mains sewerage,
- think you may require a Wastewater Management Report, or
- would like to discuss your particular DA requirements
WHAT IS covered IN A WASTEWATER MANAGEMENT REPORT?
Depending upon what specific wastewater services your project requires, a Wastewater Management Report will typically consist of three stages:
The initial investigation is a desktop study, or initial site inspection where soil samples are collected and tested. During a desktop study the topography, known soil conditions and rainfall flow paths are identified. Following the desktop study, a site assessment is performed utilising thin wall tube sampling and visual inspection of the surrounding landscape. This stage is often a valuable opportunity to speak with face-to-face with your assessing Engineer; and can be combined with your Geotechnical, Contamination, or a Site-Classification Inspections to save you both time and money.
ASSESS AND DESIGN
The soil and data logged on site is taken back to our laboratory for testing, classification and further investigation. The investigation findings is used to create a site map detailing all the identified site features and overlaying all site constraints (such as creeks, boundaries, and buildings) to determine areas on-site suitable for effluent management. From the soil and landscape we assess in accordance with Australian Standard 1547 using proprietary software to quantify the rainfall, phosphorous absorption and nutrient content of your site. The results of this process allow us to determine the most cost effective wastewater management solution for the design stage; where the site map is finalised with the treatment system, disposal method and all necessary notes.
REPORT AND ADVISE
Broadcrest's waste water management reports clearly articulate the necessary information for use by the owner, assessor and installer of the chosen Wastewater Treatment System. Our reports provide a summary of the investigation methodology, site constraints, calculations and system selection reasoning. We include an information pack with typical drawings, treatment / dispersal system explanations, and frequently asked questions for use by yourself and the installer of your choice.
