Sanitary landfill is still the most cost-effective and appropriate method for waste disposal in Iraq. The municipal solid waste has high moisture content of about 49.1% and density of 162.6 kg/m3. The organic fraction reaches about 79%. Based on the studies and reports of study area, the average waste generation rate was 0.45 kg/capita/day. The design of the base liner, leachate collection system, and final cover system for the study area landfill is described in this paper. Since the landfill is located in an arid environment, leachate generation is low and potential infiltration through the lining system is minimal. A 250 mm diameter drainage pipes have longitudinal slope 1% to reduce sedimentation and allow adequate flow capacity.

A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s. In the past, refuse was simply left in piles or thrown into pits; in archeology this is known as a midden. Some landfill sites are used for waste management purposes, such as temporary storage, consolidation and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling. Unless they are stabilized, landfills may undergo severe shaking or soil liquefaction of the ground during an earthquake. Once full the area over a landfill site may be reclaimed for other uses.

Wizards are very useful for creating a good user experience. In all businesses, interactive sessions are most beneficial. To improve the user experience, wizards in Odoo provide an interactive session. For creating wizards, we can use transient models or abstract models. This gives features of a model class except the data storing. Transient and abstract models have permanent database persistence. For them, database tables are made, and the records in such tables are kept until they are specifically erased.
