The present work investigated the modification and optimization project for the water transmission and distribution system, based on the Georefereced and smart management of pressure zones in Amlash city. In order to calibrate the distribution network, data was obtained by remote sesing and data loger of ultrasonic flowmeters and pressure gauge. Therefore, the results of the research emphasize the separation of the distribution network in the area of independent measurement based on Geospatial Information System (GIS) for the improvement of the facility. The results of the executive activities affected by the current research in 1397 resulted in a decrease of production and increase of of the city's water income

In the distribution network analysis, a step-by-step algorithm based on flow and pressure equations is used. In this method, solving energy and continuity equations in each repetition is used to analyze the branch and loop networks in separate network segments. In this way, numerically, the network was maintained by one-way pressure regulating valves with an independent function. The present work examines the baseline reclamation and development model in the District Metering Area's "DMA" and in Independent Districts and the separate sections of the network that are separated from the permanent boundaries of the network while analyzing the flow and pressure parameters. The results of this work show that the intelligence of the facility will ensure the realization of the objectives of the model of reclamation and development.

Rudbar city is the capital of Rudbar County at Guilan Province. According to the topography of the Rudbar city, there is non- homogeneity in the distribution of fluid pressure in water facilities. Density data of the incident has put the city in a row of incident cities in the province's water distribution network. Therefore, in recent years, isolated pressure zones have been designed and implemented in the framework of the reforming and optimization of the transmission and distribution system for standardizing the pressure shrinkage. Therefore, the present work shows that utilizing smart management technology for baseline pressure through remote reading of hydraulic parameters of pressure and discharge in compressive zones in the Rudbar city and the complete isolation of pressure zones is a solution to network problems. The results of the executive activities affected by the present work in the year 96 resulted in a decrease of 17 liters per second from water production and an increase of 49 percent in revenue and an increase in urban water quality.

The present work analysed the model of real condition for water distribution network of Langarud city by Geospatial modeling. Hydraulic calculations and comparison of water supply model of Langarud city in two existing variants and proposed model emphasized the modification of existing water distribution model while implementing two cases of GAP1 and GAP2 rings around the city. Along with this operation in 5 stages, creation of independent pressure zone and isolated consumption areas in the network besides the intelligent pressure management through the system of remote reading and implementation of demand management in the form of water split reform were also considered.

In this research, the relationship between spatial and non-spatial data is a tool for creating a spatially related relationship to data associated with water loss. Therefore, for the desired complication, the type of communication and its quantity are determined by a basic location-based hydraulic model and access to leakage points is provided. Comparison of the results of the computational model and pressurized fluid transfer and its location-based model made it possible to call these composite models in advanced software to determine the leakage position. Therefore, the hydraulic model is created in compliance with the Geospatial Infomaiton System (GIS) location-based system and in the HAMMER7 software under ArcGIS9-ArcMap9.3 software management and the result of the research analysed the water pressure wave and water loss.

Quick turn-based geo-reference information is a new technology that has a positive impact on the performance and efficiency of facility systems including Heating, Ventilating, Air-Conditioning & Refrigeration (HVAC&R's). The technology of signal detection through remote reading system, provide the management of facility HVAC&R through the geo-reference world area network (Webbased GIS) based on geographic information system (GIS). This method as a new concept in the control science and optimize energy consumption can be an effective factor in design, maintenance, energy consumption management, and commissioning of the facilities and building industry. Also, this method provides online control of energy consumption of the facilities and building industry. So in this work, the model of control of HVAC&R in the context with GIS and Web-based GIS were investigated. The empirical results besides the regression mathematical analysis show that this model is able to predict and evaluate energy consumption.

The fuzzy logic is a new technique which refers to professional knowledge instead of complex mathematical modelling for progressive systems. In this work the fuzzy logic performance investigated due to high speed data intercommunication for urban water distribution system. Therefore present work analytically concentrated on decreasing rate for Minimum Night Flow “MNF” of Rasht city water distribution network by evaluate of the two variances of water transmission system. These variances were analysed by the WATERGEMS8.2 software as a subprogram of ArcGIS9-ArcMap9.3. The results showed that the 200 lit / secdecreasing of Minimum Night Flow for variant of water transmission from 50000 m3 Saravan water reservoir to 40000 m3 water reservoirs at east and west side in Rasht city.

Present research in order to reduce non-revenue water through cluster testing of meters was arranged in the Rasht city's water plant. In this study, rapid data intercommunication model based on Geography Information System GIS were considered in District Metering Area DMA. During the study, the consumption curve, Minimum Night Flow MNF and pressure distribution curves by water distribution network hydraulic model was investigated. The hydraulic model in compliance with GIS and WATERGEMS8.2 software in the form WATERGEMS8.2 was defined. The results of research ordered the change of 4058 meters with a negative measuring error.
