How to manage septic tanks and rainwater wells properly?

The approach of \"responsibility assigned to individual households\" can be adopted to allocate tasks to each unit; the safety and environmental management department of each unit should assign dedicated personnel to conduct regular inspections and supervise compliance with established regulations.

The company’s Safety and Environment Department assigns dedicated personnel to carry out regular inspections and supervision, and there are specific individuals responsible for the cleanup work.

It’s normal to have sludge in septic tanks, but is there also wood sticks inside? Also, has an analysis been done for this work in a confined space? It seems that the safety measures aren’t adequate; the workers weren’t even wearing gloves.

Temporary workers are not given gloves. Temporary workers have low costs; their lives are cheap as well, and their labor is even less valuable.

Upon seeing the image, it became clear that there are certain things that really shouldn’t be inside this system. Therefore, the appropriate solution is to properly manage the manhole covers – preventing them from being opened arbitrarily and ensuring they are closed promptly after use, so as to stop foreign objects from entering the system. Second, maintain good hygiene in the surrounding area to prevent large amounts of dust from entering the well along with rainwater, which could lead to an excessive amount of sludge. Third, establish a responsibility system to clarify the main responsibilities, dividing them by region and unit; each well within a region is responsible for its own cleaning. Fourth, it is necessary to strengthen assessment and inspection, using the evaluation system based on responsibilities to drive improvements in work quality.

It’s sufficient to use open ditches for everything; there should be two ditches around the workshop – one for rainwater and one for sewage. The sewage goes in one ditch while the rainwater goes in the other, both using the open-ditch system. The sewage ditch is connected to the sewage tank, and valves are installed at the connection point. These valves should be kept open normally, and opened at the beginning of rainy days before closing them later on.

It’s mainly due to people’s lack of sense of responsibility and environmental awareness; they often think it’s normal to pour garbage and trash into sewer drains. Biodegradable organic waste can still break down in water and mix with the sediment； If bricks, stones, iron pieces, and hard-to-degrade plastic products are thrown in, it can easily cause blockages in the drainage system. Not only does the spilled wastewater pollute the environment, but it also creates difficulties for sanitation workers and temporary employees hired by municipal authorities. Working in humid and hot environments such as septic tanks often leads to poisoning. Environmental protection should start with individual actions, with small things in our daily lives

The discussions in this post were all focused on the subject at hand; only 4#@altpage mentioned the issue of working in confined spaces. I thought that it would be sufficient to take overall responsibility for cleaning sewage wells and stormwater drains – with a focus mainly on sewage wells – by classifying these wells as part of the \"confined space operation management\" framework. Cleaning operations should require an operation permit, supervision, oxygen level monitoring, as well as ventilation measures or breathing masks; there have been many tragic lessons learned in this regard.

I agree with you! This is the key issue that needs to be discussed, as accidents often occur during the cleaning of septic tanks; therefore, management efforts must include regulations for working in confined spaces in order to prevent incidents such as poisoning and suffocation. This is also an area where management is currently weak!
