Comprehensive On-site Wastewater Services

Caldera Environmental provides a range of services to support the effective management of on-site wastewater systems. Our services include:

  • Site Assessment and Design: We conduct thorough site assessments to determine the most suitable location and design for your OSSM system. This includes evaluating soil type, topography, and proximity to water sources to ensure optimal system performance and environmental protection.

  • System Installation and Management: With guidance from our team, an OSSM can provide efficient storage and treatment of your household wastewater. We oversee the installation process to ensure compliance with local regulations and industry standards. Our team also provides ongoing management and maintenance services to keep your system functioning effectively.

  • Wastewater Disposal and Infiltration: We offer solutions for the safe disposal and infiltration of treated wastewater within your property boundary. This includes designing and implementing systems such as absorption trenches, evapotranspiration beds, and subsurface irrigation to manage wastewater sustainably.

  • Remediation and Upgrades: If your existing OSSM system is not performing adequately, we provide remediation and upgrade services to improve its efficiency and compliance. This may involve repairing or replacing components, enhancing treatment processes, or expanding system capacity.

Regulatory Compliance and Standards

Certain councils have set specific standards for on-site wastewater management to protect public health and the environment. Caldera Environmental ensures that all OSSM systems comply with these standards, including those outlined in the Environment Protection Authority's guidelines and local council regulations. Compliance with these standards is essential for obtaining development approvals and avoiding potential fines or legal issues.

Importance of Professional Expertise

Engaging experienced and knowledgeable environmental consultants is essential for effective on-site wastewater management. Caldera Environmental’s team brings a wealth of expertise, ensuring that every project is handled with precision and care. Our commitment to excellence and compliance ensures that we deliver results that are not only effective but also sustainable and legally sound.

If your property is not connected to the Council’s reticulated town sewer system, you may need or may already have an On-Site Sewage Management (OSSM) system. Council will need the development or assessment of your OSSM to be done by an Environmental Consultant to ensure it is compliant and capable to effectively manage site based grey water and human waste. 

Importance of On-site Wastewater Management

On-site Wastewater Investigations, provided by Caldera Environmental, offer options for wastewater disposal, infiltration, and remediation within your property boundary to ensure Council compliance with your development. This includes managing wastewater from both black-water (toilet) and grey-water (bathroom, laundry, and kitchen). Proper management of on-site wastewater is crucial for protecting public health, preventing environmental contamination, and ensuring the sustainable use of water resources.
