Why is it important to calculate the size of the septic tank correctly?<\/strong><\/h2>\nA tank that is too small will fill up quickly, causing odours, leaks or the need for frequent emptying<\/strong>.
On the other hand, an oversized tank can slow down natural decomposition<\/strong> and affect the internal biological process.<\/p>\nIn summary: a septic tank of the right size is more efficient, economical and environmentally friendly.<\/strong><\/p>\nIf you have any doubts about the capacity of the current system, you can request an inspection with a CCTV camera<\/a><\/strong>. This allows us to detect the actual volume and any possible obstructions without the need for construction work.<\/p>\nFactors influencing volume calculation<\/strong><\/h2>\n\ud83e\uddcd\u200d\u2642\ufe0f 1.
