Septic design for residential and commercial properties focuses on creating effective systems for treating and managing wastewater on-site. Residential systems typically comprise of a septic tank and a drain field, designed based on household size and water usage patterns. In contrast, commercial septic systems are more extensive and often need multiple tanks and specialized components to handle larger volumes of wastewater and diverse waste types, such as those from restaurants or industrial facilities. Both systems must adhere to numerous regulations, with careful site evaluations and soil assessments performed to ensure efficient operation and longevity, ultimately preventing system failures and costly repairs.
