We also look at the accessibility of your tank lids; if they are buried deep underground or hidden under landscaping, extra labor is required to reach them.

Frequently asked in Cambridge

What are the causes of septic pump repairs?

Septic pump repairs are often needed due to electrical issues, such as a tripped breaker, blown fuse, or faulty wiring. Mechanical failures, like a worn-out motor, damaged impeller, or a malfunctioning float switch, are also common. Obstructions in the pump or discharge line, caused by debris or improper disposal of materials, can lead to the pump working harder or failing. In older systems, the pump itself may simply reach the end of its lifespan and require replacement. Regular inspections can help identify potential issues before they lead to a complete failure.

What are the different types of septic systems?

Septic systems vary depending on site conditions and local regulations. Conventional systems use a septic tank followed by a drain field of trenches. Aerobic treatment units (ATUs) introduce oxygen for faster waste breakdown. Drip distribution systems deliver effluent through small tubes. Mound systems are used for poor drainage, with a raised sand bed. Evaporation systems are suitable for arid climates. Advanced treatment systems are often required in densely populated areas like Cambridge to meet strict environmental standards and minimize their footprint. The best type depends on your specific property and needs.

When should a septic tank be inspected?

A septic tank should be inspected every 3 to 5 years for typical residential use. However, if you have a garbage disposal, frequently entertain guests, or notice any signs of trouble like slow drains, foul odors, or plumbing backups, an inspection should be scheduled sooner. Inspections are also critical when purchasing a property to assess the condition of the existing system. A professional inspection can identify potential issues early, allowing for timely repairs and preventing costly emergencies, thus ensuring the system's longevity and proper function.

What is a septic tank?

A septic tank is a crucial underground component of an onsite wastewater treatment system. It's a watertight container that receives all wastewater from a household. Inside the tank, solid waste settles to the bottom as sludge, and lighter materials like grease and oil float to the top as scum. Natural bacteria within the tank begin to break down some of the organic waste. The liquid effluent then flows out of the tank into a drain field for further treatment and dispersal into the soil, protecting groundwater quality.

What are septic tank cleaning services?

Septic tank cleaning services involve the professional removal of accumulated sludge and scum from the septic tank. This process, often called pumping, is essential for preventing solids from entering and clogging the drain field, which can lead to system failure. Typically performed every 3 to 5 years, these services ensure the tank maintains its capacity and functions efficiently. Beyond pumping, cleaning services often include an inspection of the tank's interior for any signs of damage, ensuring the overall health and longevity of the septic system.

What is septic tank cleaning?

Septic tank cleaning, commonly known as septic pumping, is the process of physically removing accumulated sludge and scum from the septic tank. This routine maintenance is vital to prevent these solid materials from overflowing into the drain field, which can cause blockages and lead to system failure. The process usually involves a specialized vacuum truck. Regular cleaning, typically every 3 to 5 years, ensures the tank operates effectively and prolongs the life of the entire septic system, safeguarding your property and the environment.

How does a septic tank work?

A septic tank acts as the primary treatment stage for wastewater in an onsite system. All household wastewater enters the tank, where solids sink to the bottom as sludge and lighter materials float as scum. Naturally occurring bacteria begin to decompose some of this organic waste. The clarified liquid effluent then exits the tank and flows into a drain field, also known as a leach field. Here, the effluent is further filtered and treated by the soil before being dispersed into the groundwater, thus completing the treatment cycle.
