The work on sanitary landfill depends on number of factors . The preparation work is done based on technological project, the sanitary landfill is constructed and is worked on , while other technical details that are used to develop rest of technical documentation. The schedule of work is given in work instruction and waste disposal plan. We are emphasizing that after usage permit is obtained the water usage permit and certificate must be obtained. The employees need to take in consideration that all changes must be properly documented

The following sign must be on the entrance: WASTE LANDFILL - KAŠTIJUN, 1ST CATEGORY LANDFILL, JP "Herculanea" d.o.o. - PULA, hours of operation: MONDAY-FRIDAY 7-19 h. The landfill must be open 7 days a week, and closed on weekends. The operating hours are from 7 to 19 h in first and second shift, while the security guards are present in the third shift.

The landfill must be fenced with fence at least 2m high, and entrance will be possible only via access road through automatic gate. The guard directs vehicle at place of disposal. The exact place of disposal will be determined by landfill supervisor. The only vehicles allowed on site are municipal waste company vehicles, as well as other companies and private transport vehicles that have permission for disposing waste in this location. The residents can deliver waste up to 0,5 m3 volume. Other vehicles must obtained permission from landfill owner and they must give to security guard before entrance,
The guards on entrance 2 will perform the inspection of waste as well as on Entrance 1 and keep records on waste inspections. The records contain following data:
? vehicle data (tag no, type of vehicle, and usable volume)
? waste data: type (municipal, bulky, construction, green, technological), quantity (since there is no volume, usable volume of vehicle is used) and waste owner
? type of waste disposal, covering of waste and ensuring stability of disposed waste
? inspection of content and quantity of landfill gases,
? content of leachate water, content and quality of ground water, drainage of precipitation water and recultivating of part of landfill filled up with waste.
? emergency situations (fire, explosion, weather related problems)
? security guards (name and notes)

The integral part of the records are waste documentation (documents on technological waste), equipment used, used material, inspection and measures undertaken under environmental inspection personnel orders and overview of natural and emergency events on landfill

The responsible person for landfill is landfill supervisor. The dozer operator is also on the landfill and performs supervisor's duty if supervisor is absent.

The employees must be trained to operate landfill in safe manner and they must adhere to Workplace protection Law and Fire protection law. They should also be educated on landfill operation technology.

We also list the main characteristics of sanitary landfill: this is disposal system where waste is disposed under control on prepared ground, so harmful effects of uncontrolled disposal are avoided. After designed height of waste is achieved, the landfill will be closed and afterwards closely monitored
• the preparation of location includes::
a) excavation and transfer of waste disposed on ground around hole (carstic terrain) outside the planned work zone, with slope 1:2,5-1:3
b) return of waste on newly prepared surface with waste compacting and coveting of top layer of waste
c) construction of 3 wells on the deepest part of landfill and installation of pumps for recirculation of water collected in waste
• construction of road on location and access road
• construction of boundary channels for precipitation waters
• construction of degasification system (pipes+torch)
• continuation of operation and remediation of landfill. This will be achieved by placing inert material dike with waste slope 1:3 and covering of old waste with leveling layer
• disposal of waste with waste compacting
• covering of waste with water impermeable material (clay) or LDPE layer
• waste compacting to designed height
• placement of finishing layer on filled up parts of landfill (landfill closing)
• planting greenery
• monitoring

The waste goes through microbiological decomposition, so the organic fraction of waste will be demineralized. The process inside deposed waste cause waste settlement
