Precast 1500 Gallon Concrete Septic Tank Overview
Monolithic 1500 gallon septic tanks are designed to hold 1500 gallons of liquid.
For 5 bedroom home waste water applications and pump tank stations, this size of septic tank is the optimal choice.
Our team at A.J. Foss has the experience and expertise to create precast concrete tanks with robust structural integrity. For each job, every size and style of septic tank we manufacture meets all health code requirements and best-practice requirements of ASTM C 1227 & NPCA.
Choose the Inlet and Outlet Option You Need
For many local area residential septic applications, the monolithic, top-seam style concrete septic tank is ideal.
Plumbers can run pipes that aggregate waste water from home drains to inlet areas on the side or middle of this type of tank. This plumbing option is also available for outlet pipes that connect from either side or center outlet fittings and outlet connection sizes to a leach field.
Polylok IV closed end plumbing boots are used for the tank’s penetrations. They do a great job of providing water tightness with flexible connection to the pipes coming into and going out of the precast structure.

Frequently Asked Questions
How much does a 1500 gallon capacity precast concrete septic tank cost?

How many bedrooms does a 1500 gallon septic tank support?
Answer: In New Hampshire a 1500 gallon septic tank can service a home with up to 5 bedrooms.
Are one compartment tanks ideal for properties with high water tables?
Yes. Ideally you want a monolithic septic tank which is a one compartment septic tank with the seam at the very top of the septic tank in high water table situations. This is a common choice for properties with high water tables, since the liquid is below the lid so nothing can leak in or out.
How much does a 1500 gallon concrete septic tank weigh?
The shipping weight of our 1500 gallon tanks is approximately 12,500 lbs., but weight varies slightly with precast manufacturers depending on the dimensions, wall thickness, floor & top thickness, & rebar reinforcement.
Can you drive over a 1500 gallon concrete septic tank?
It depends on the septic tank design rating. We manufacture to 3 variations of tank description and design ratings: H-10 loading precast septic tanks are suitable for pedestrian traffic with 300 lbs. of live load per square foot plus 3’ of burial depth. HD is suitable for burial depth up to 5’. H-20 is suitable for drive over traffic and up to 6’ of burial depth.
Can you install a 1500 gallon concrete one compartment septic tank in one piece?
Yes, we can install 1500 gallon low profile septic tanks in one piece. Our septic tank delivery trucks and cranes are capable of setting even larger tank sizes (up to a 1750 gallon tank) in one piece. Because these concrete precast tanks are in one piece, the installation time for your concrete septic tank delivery is reduced to a shorter period of time.
When is septic tank installation of a tank above ground appropriate?
Installation of a concrete tank above ground is appropriate for a sand mound septic system. This system is recommended when site conditions for your tank location do not allow for installation of concrete tanks such as proven conventional sometimes called old-fashioned concrete septic tanks.
