The hydraulic installations must be designed and built in such a way as to ensure the uninterrupted supply of water, in sufficient quantity, at adequate pressures and speeds, under appropriate conditions for the development of human activities and for human consumption, ensuring comfort to users including the reduction of noise levels in pipes. These conditions are met from the technical standards that determine hydraulic parameters and calculation methods to be followed by designers, who take into account a theoretical study of pipe and connection sizing that, in practice, due to water consumption and practical operation, ended up causing the adequacy of manufacturers of sanitary appliances, development of more efficient technologies. Through laboratory tests, many manufacturers began to provide essential technical information for the development of more assertive projects, such as the actual water consumption of the appliances, especially the characteristic curves of flow as a function of pressure, fundamental for use in the design of water systems and for the development of new methods, in order to consider the variable flow in the points of consumption. Tied to this new scenario the updating of technical standards among them the NBR 5626, which expands the possibility of using specific data of manufacturers and sizing of facilities. In this context, the present work proposed a comparative study of the sizing methodologies of the hydraulic installations of cold water installed in a hospital located in Belém do Pará, according to the update of NBR 5626/2020 building systems of cold water and hot water - design, execution, operation and maintenance that cancels and replaces NBR 5626/1998 cold water building facilities. Thus, the research was divided into step (1) bibliographic research, presentation of the study area and data collection, step (2) dimensioning of the cold water system considering nbr 5626/98, step (3): sizing of the cold water system considering NBR 5626/20 and step (4) analysis of the results. In general, with this case study, a practical approach was obtained to apply the updated parameters of the NBR 5626/2020 regulation in relation to NBR 5626/1998, presenting flow values, determined by the specific information of each sanitary piece, where we had an increase in this parameter, as to the diameter we had in most of the preumadas the decrease directly interfering in the load loss that increased and how much available pressure a decrease.

Public cleaning services for sanitary sewage collection networks generate waste. Proper management of this waste helps to extend the useful life of landfills, prevent environmental degradation and prevent sanitation service providers from becoming subject to civil and criminal penalties, according to article n. 60 of the environmental crimes law n. 9,605/1998. The objective is to present a proposal for a methodology for managing waste removed in the cleaning of sewage collection networks sanitary - SCNS. Developed in the area Sewage Treatment Station-STS II, at Avenue Tavares Bastos, S 1°24'18.4" W 48°26'52.3". The work was carried out in 3 stages, with the first stage determining the volume (m³) of non-coarse waste, decantable in the waste tanks of hydrojet trucks, removed in the SCN cleanings, in the year 2022, considering for comparative purposes the 3 rainiest and even months of that year. In the volumetric determination, a mathematical model for determining volumes of horizontal cylinders was used and, to validate this model, cubages were carried out, with a 1m³ stretcher, of the decantable waste from the tanks of two trucks, in triplicate, and the arithmetic means of the volumes obtained were compared. In the 2nd stage, the technically suitable location was identified to: package, sanitize and dispose of the waste removed in the SCN cleanings for final disposal. To this end, the characteristics of the SSS were analyzed, where the waste in question is concentrated, considering the availability of area for expansion, security (personal and property) and the proximity of a preliminary sewage station unit for treatment of the liquid part. Finally, in the 3rd stage, a proposal for a methodology for managing this waste was presented. To this end, all the steps from the previous stages were compiled sequentially, from the control of the information on the service orders for carrying out the SCN cleanings to the final disposal of the waste generated in this SCN cleaning. As a result, the volume values determined for the three rainiest months were 3.182 m³, and for the three less rainy months, 3.147 m³. The rainy season was considered the most critical for a possible annual extrapolation. The location with geographic coordinates 1°24'17.4"S 48°26'49.9"W, on the STS II site, was adopted for the implementation of a device with impermeable flooring and transparent covering, interconnected to pumping station 4 of STS II. It was concluded that it is possible to apply the methodology presented for the management of waste removed in the cleaning of SCN, for immediate disposal in a sanitary landfill. For the practice of reusing this waste, specific studies for this purpose will be essential
