The physical characterization of the domiciliary solid wastes of the cities of Belém and Ananindeua of the Belém Metropolitan Region, related with the social and economic situation, its secular evolution, its recycling potentiality and with the reduction of costs with the urban cleanness. Initially, there were identified the collect routes practiced in each one of the sectors to be sampled. After that, it was initiated characterization in the Aurá Final Destiny Complex, where the samples of the selected routes had been analyzed. After homogenization process, there was removed a cubical meter of solid wastes of the trips of each route, where it was realized the characterization and selection of the components of the wastes. At the end of this stage the gotten results had been statistically treated, having the following average values respectively for the cities of Belém and Ananindeua: Specific Apparent Humid Weight 202,03 and 180,09 kg/m3; plastic 14,98 % and 16,27%t; paper and cardboard 17,06% and 17,36%; metals 2,64% and 3,87%; glass 1,52% and 2,96%; decomposable organic matter (compostable) 45,89% and 42, 34%; and others 17,91% and 17,20%. The gotten results call the special attention in the variation in the Specific Apparent Humid Weight, being the Ananindeuas of lesser value in function of the biggest content of plastics, glasses and metals; and of an organic matter lesser content. These differences basically must be function of two factors that are: Ananindeua is a dormitory city of Belém and in Belém the selective collect is more efficient because of the existence of a selectors cooperative stimulated by the government. The monthly values only added with the recycling are: Belém (lr = 100 %) R$ 11.089.740,90; Belém (Ir = brazilian average) R$ 3.256.155,60; Ananindeua (Ir = 100%) R$ 2.228.510,40; Ananindeua (Ir = brazilian average) R$ 1.160.136,90. Total Values with the Recycling without Selective Collect by the government are: Belém (Ir = 100%) R$ 1.080.547,50; Belém (Ir = brazilian average) R$ 402.165,60; Ananindeua (Ir = 100%) R$ 532.353,60; Ananindeua (Ir = brazilian average) R$ 125.676,00. The reached results satisfy the work objective, tracing of this form, the solid wastes production profile of the cities of Belém and Ananindeua in the year of 2006.

(Universidade Federal do Pará, 2004-09-20) LIMA, Henrique Nazareno Santos; LIMA, José Júlio Ferreira; http://lattes.cnpq.br/5176390429456548
This dissertation aims at giving a more specific account of the term sanitary road utilised in sanitary enginnering. It applies principles used in the projects of canal marginal roads, narrow short streets and trunk roads. The study is based on the case of Estrada Nova basin located in the city of Belem. After a characterisation of its fuctioning, its relationships with the urbanistc control is explored in order to be more compatible with land use control. The result of the study presents elements for the a reconsideration fo the definition wihch incorporates the urbanistic situation and needs for drainage projects to be more integrated with the urbanistic functioning of the city.
