Five misunderstandings of rural septic tank construction, to prevent collapse and leakage, you need to keep these standards in mind

In the environmental construction of rural areas, the construction quality of septic tanks is directly related to the health and ecological environment of the village. Here are five common mistakes about septic tank construction that villagers should be warn of.

First of all, the construction of retaining walls is an important part of the septic tank. The correct way to do this is to use 24 or 37 walls, which can effectively withstand the pressure. However, in order to reduce costs, some projects ignore this requirement, resulting in the retaining wall is not firm and prone to collapse.

Secondly, the bottom of the septic tank must be poured with C15 concrete cushion, which is the basic construction standard. The thickness of the cushion should reach at least 10 cm to ensure the stability and tightness of the bottom structure.

In the proportion setting of the septic tank, the correct ratio should be 2:1:3 between the sedimentation tank, the anaerobic fermentation tank and the clear water tank. This ratio is a reasonable design verified by practice, which can not only ensure the efficiency of sewage treatment, but also effectively reduce pollution.

Another common mistake is the use of hollow bricks and perforated bricks in the construction of septic tanks. The high porosity of this type of material is not conducive to impermeability and warmth, and in severe cases, it will lead to leakage and freezing of septic tanks.

Finally, the setting of the septic tank cover is also a key factor in determining its effectiveness and ease of maintenance. The cover plate should be poured as a whole, and the manure excavation port should be reserved. In this way, it can be easily cleaned and maintained when needed, avoiding subsequent troubles and costs.

These mistakes may seem simple, but in fact, each point is related to the service life of the septic tank and the effectiveness of its treatment. When villagers build septic tanks, they should strictly follow the construction specifications to ensure that every step meets the standards. Only in this way can we build a septic tank that is both environmentally friendly and practical, contributing to a clean environment in the village.
