Many regions require permits for excavation and land clearing, particularly for large-scale projects. Permits may be necessary to ensure compliance with environmental regulations, protect natural habitats or avoid disruptions to underground utilities. 

Local councils may require soil and erosion control plans, especially if the project involves significant land disturbance. Some areas also require environmental impact assessments, particularly if the work affects protected wildlife or vegetation. Before starting any project, consult local authorities to ensure all necessary permits are secured.

Soil erosion is a common challenge after land clearing, especially on sloped terrain. To prevent erosion, it’s essential to use techniques such as mulching, planting ground cover or installing silt fences. Mulching stabilises the soil and prevents surface runoff during rain, while fast-growing grasses or shrubs create root systems that hold the soil in place. In larger projects, terracing or installing retaining walls may be necessary to control water flow. Erosion control measures not only protect the cleared land but also ensure compliance with environmental regulations.

The size of your septic tank depends on the number of people living on the property and the daily water usage. Residential properties typically require tanks between 1,000 to 1,500 gallons. For larger households or commercial properties, a larger tank may be needed. Local regulations may specify minimum sizes, so it’s essential to check with your local council. An undersized septic tank can lead to frequent backups, while an oversized tank may not function efficiently due to insufficient water flow.

A drain field, also known as a leach field, is an essential part of a septic system. It consists of a network of perforated pipes buried in trenches filled with gravel or sand. After wastewater leaves the septic tank, it flows into the drain field, slowly percolating through the soil. The soil acts as a natural filter, removing harmful bacteria and contaminants before the water re-enters the groundwater system. Proper maintenance, such as keeping heavy equipment off the drain field and avoiding tree planting nearby, is crucial to prevent damage.
