The Difference Between A Septic and A Holding Tank


Holding Tank vs. Septic Tank: Key Differences

While both holding tanks and septic tanks can contain sewage and wastewater, a septic tank is part of a larger system that also treats the wastewater and returns it to the groundwater. A holding tank simply stores the wastewater and sewage until a pro can pump it away.

Septic tanks have baffles that allow wastewater in and effluent out. A major difference between a holding tank and a septic tank is that you need to pump a holding tank every one to four weeks, while you should pump a septic tank every three to five years on average.

A holding tank serves as an underground reservoir for wastewater, distinct from septic systems. The home directs wastewater solely into the tank, which lacks connections to other pipes. Periodically, professionals pump out the wastewater, facilitated by a lid at the tank’s top. Alarm systems are integral, notifying homeowners when the tank nears capacity to prevent overflow incidents.

Septic Systems Explained

In rural settings with space constraints or poor soil drainage, holding tanks offer advantages over septic systems. Their installation requires less space and simpler infrastructure, translating to lower upfront costs. Furthermore, the alarm system helps manage maintenance, reducing the risk of environmental harm from overflow.

However, holding tanks entail drawbacks compared to septic systems. They demand frequent pumping, often weekly or biweekly, due to the absence of drainage systems. Ongoing maintenance expenses may outweigh the initial cost savings as a result. Moreover, the stricter permitting process reflects the environmental risks posed by unprocessed wastewater, leading to longer wait times and higher costs for installation permits.

In summary, while holding tanks offer simplicity and cost-efficiency, especially for space-constrained or poorly draining areas, their maintenance demands and permitting requirements necessitate careful consideration against septic systems. Balancing the upfront savings with long-term maintenance costs and environmental implications is essential when deciding on wastewater management solutions.
