In contrast, plastic septic tanks are significantly lighter, offering easier transportation and simpler installation procedures. Their reduced weight and pre-fitted components can streamline the overall process, making them a more cost-effective choice for many homeowners and small-scale commercial projects. Nevertheless, plastic tanks may be more susceptible to damage from external factors, such as heavy machinery or shifting soil conditions.
Tank Capacity and Sizing
Determining the appropriate septic tank size is crucial for the system’s effective performance and compliance with local regulations. The tank’s capacity is typically based on the estimated daily wastewater flow, which is influenced by factors such as the number of bedrooms, occupancy, and anticipated water usage patterns. Consulting with a registered onsite wastewater practitioner or a local septic system specialist can help double-check that the selected tank size aligns with your specific needs and site conditions.
Installation Considerations
The installation process for a septic system, including the tank, can be a complex and labour-intensive undertaking. Prefabricated septic tank modules, however, offer a streamlined approach that can simplify the overall project.
Site Preparation
Before installation can begin, the site might want to be properly prepared. This often involves excavating the designated area, ensuring the soil is suitable for the septic system, and addressing any potential obstacles or environmental considerations, such as groundwater levels or nearby protected areas.
Excavation and Placement
Prefabricated septic tank modules are designed for efficient on-site installation, often requiring less time and labour compared to traditional in-situ construction methods. The lightweight nature of plastic tanks, in particular, can significantly reduce the need for heavy equipment, making them a more accessible option in areas with limited access or tight spaces.
