Concrete septic tank 3,000 liters. with outlet prefilter

Resistance and durability, it could be said that septic tanks are for life, unlike plastic septic tanks, in which there is no high risk of breakage during installation.

Prefabricated septic tank operation

When the water enters the pit, the heavier materials are separated by decantation and travel to the bottom of the pit, the less dense materials such as soaps, fats, etc... form a layer that floats.

The materials at the bottom decompose due to the effect of anaerobic bacteria, this creates a primary sludge that over time can be evacuated by an authorized company.

The clean water comes out first passing through a filter that prevents suspended solids from coming out.

These pits can receive all the water from a home or rural property, sewage, sink water and even rainwater, although it is not recommended because a large amount of water can exceed the capacity of the pit.

Initially, this volume can be considered valid for a household of 6 people. It is considered that an adequate minimum volume would be 500 L/person.

How much stone do I need?

How much stone do I need for the floor?

For boulders and gravel:
• ±80kg per m², based on a 5cm layer. *For grain sizes >32mm a thicker layer is necessary. • Consumption per bag: 1000kg = 0.625m³.
• Covering capacity: ±12.5m² with a layer of 5 cm.

For pine bark:
• ±70L per m², based on a 5cm layer.
• Consumption per bag: 1000L = ±1m³ = ±600kg
• Covering capacity: ±14m² with a layer of 5 cm.

For volcanic, slate and chamotte:
• ±50kg per m², based on a 5cm layer.
• Consumption per bag: 1000kg = ±1m³
• Covering capacity: ±20m² with a layer of 5 cm

How much stone do I need to fill a gabion?

Density of ±1,650kg per 1m³.

The calculation is very easy to understand with an example, if you have a 100x50x30 cm gabion. you have to do the following accounts:
1x0.5x0.3= 0.15m³
0.15x1.650= 247.50kg. of stone.
*It is always good to calculate an extra 5%, since when the gabions are filled they widen a little and there is always a little more stone included than in the theoretical calculations.

Clarifications

ATTENTION!

Granulometries are sieve sizes

The actual sizes may vary slightly, since when we talk about a 60-80mm stone, for example, it means that the stones pass through a 80x80mm square mesh. and they do not pass through a 60x60mm one.
A 100mm stone can pass through that 80x80 mesh. long and 65mm. wide so there may be a percentage of stones greater than 80 and less than 60mm.

stone breaking

On the other hand, in stones larger than 60mm. There is a percentage of up to 10% of stones that can break during classification, washing, loading and unloading. Today we do not have machinery that prevents these breakages.

In the photos you can see, you only see real products, no broken parts have been removed.

Dust and sand in products

This product is not washed, so it contains dust, sand and even traces of other products due to processing and transportation. This is not a problem when using it; The stone will wash itself over time or you can pour water on it before using it.
