Instructions to owners and contractors who wish to build a provision for the construction of a Private Sewer.

If you wish to build a provision for the construction of a Private Sewer for a property which is located in areas where the main sewerage system is not yet operational, the LSDB provides the following useful instructions:

• The connection shaft (that is the shaft built where the plot borders the street) must be made of concrete or plastic, it has to be waterproof and its internal dimensions must be 75×75. Its depth has to be 130 cm from the pavement surface, while a flow channel has to be formed at the bottom of the shaft. The shaft cover must be made of cast iron or rolled iron in accordance with standard EN124 and its minimum dimensions should be 60 Χ 45 cm.
• The new shafts that will be connected with the sewerage system and which will be located inside your property’s yard must be made of concrete or plastic and they have to be waterproof, while a flow channel has to be formed at the bottom of the shafts. The shaft’s internal dimensions must be 45X45 cm and the shaft cover must be made of either cast iron or rolled iron in accordance with standard EN 124, while its minimum dimensions should be 45X45 cm.
• The sewer pipes must be made of Upvc plastic with a diameter of 110 mm in accordance with standard EN 1401 (in orange colour) and must be installed with a minimum gradient of 1%.
• In case the sewerage has to be pumped from a basement or a sub-basement, you are required to contact the LSDB to receive proper guidance regarding the dimensions of the pumping station to be built, as well as about the number and specifications of the sewerage pumps to be installed.
• In case the properties include restaurants, then a grease trap must be constructed and you must again contact the LSDB for guidance regarding the size and layout of the grease trap.

It must be noted that model blueprints for the construction of shafts, pipe installation, the construction of pumping stations and grease traps are available at the LSDB and can be sent to you by fax or you can also choose to receive them from the LSDB’s offices or even retrieve them on these websites.
