pit Before than to start arranging the cesspool on your site, it is worth knowing where it is better to place it. For this you should get acquainted with SanPiN 42-128-4690-88 and SNiP 30-02-97. These documents indicate the general requirements for the location of sewage treatment plants, septic tanks and other sewage systems and devices.

The first indicator is the distance of the sump from the house and other buildings. According to the provisions of SanPin, this figure should not be less than 20 meters. Such a requirement proceeds from the fact that unpleasant, and most importantly, harmful gases to human health emanate from impurities. The exception for the removal of summer kitchens and make-up time, in this case, the distance can be reduced. The place is chosen at the discretion of the homeowner in the range from 8 to 10 meters to the buildings. The documents indicate the maximum distance, it is 100 meters.

Also, building codes and sanitary regulations impose strict requirements on the location of drain holes from various sources of drinking water. So, if a well or spring is located nearby, then the distance to it should be at least 50 meters.

If the areas are small in size, it may be impossible to fulfill all the requirements. In this case, on the advice of specialists, it is better to resort to cooperation. For all neighbors living on the same line, a single well or artesian well is constructed. So you can avoid water pollution from cesspools of neighbors.

Neighbors are not forgotten in the documents. So, the distance from the edge of the drain hole and the adjacent area should be more than 1 meter. But, as a rule, this indicator needs to be done more in order not to quarrel with neighbors. According to the current SanPiN, if a controversial situation has arisen, then the location of the cesspool can be determined by the administrative commission of the local Council.

  • Creolin - 5%;

The main thing is that the smell does not interfere with comfortable living. To solve this problem, you can use biological products that contain colonies of bacteria. With their help sewage will be processed into safe sludge.

When creating hermetic structures, the main requirement is to ensure that the truck of the vacuum truck is accessible. Since the wastewater will not fall into the ground, the tank will quickly fill up. In this case, it is not allowed to overflow over the edges of the pit.
