Frequently Asked Questions
Regular maintenance is crucial for septic systems. Generally, septic tanks should be pumped every 1 to 3 years, depending on household size and tank capacity. Routine pumping prevents system failures and extends the lifespan of the septic system.
Regulations often mandate that properties within a certain distance (e.g., 300 feet) of a public sewer line must connect to the municipal system rather than installing a private septic tank. This requirement ensures efficient wastewater management and environmental protection.
The longevity of a septic system depends on the materials used, design quality, installation practices, and ongoing maintenance. Concrete septic tanks, for instance, can last 50 years or more if properly maintained. Regular inspections and avoiding harmful substances can prolong system life.
