2.1 Diagnosis of Current Situation
Water System General
The system of existing drinking water supply at the National University of Education Enrique Guzmán Valle surface resources is done from a ditch that runs along the 870 m elevation and ground water resources from a well drilled in the area of \u200b\u200bthe campus. The canal has
pre-Hispanic origin and was initially for irrigation.
In the following paragraphs a description of each of the components of this system. Drivetrain
The driveline consists of a simple concrete gutter in good shape with a length of about 50 m in length which carries the water from the canal to the treatment plant.
Treatment Plant Treatment Plant account initially with 3 sand traps, which serve as sedimentation of small solid particles. The 3 sand traps are in good condition. Later during the trip
water tanks are prefabricated (fiber glass and plastic) that function as a coagulant dose of sodium hypochlorite, which are added to water. There is a well mixing of coagulant is not used.
Following this, the water reaches a continuous flocculation and two clarifiers where solids settle to the microscopic.
water finally reaches a 48 m3 tank, where by means of two pumps that run alternately (6 hours each) the water is driven to 05 rapid sand filters and finally arriving at a base supported rectangular reservoir of 520 m3 capacity, located 11 meters from the tank. The pumping rate is 18 l / s.
There is a disinfection system that is used by injecting chlorine solution to the discharge pipe of the tank, but it is done before the water enters the filter and not after as it should be. Furthermore, the disinfection is performed with sodium hypochlorite and no chlorine gas, which is normally used in these cases. Poza
and Drive Line
There is a water well where the existing underground forces water through PVC pipes class 10 to a circular base reservoir, located on the side of the rectangular base reservoir. The pipe length is 640 m and a diameter of 6 ".
drive line of the tank is 4 ° in diameter, galvanized iron material with a length more than 30 years. Storage Reservoirs
In the study area there are two storage reservoirs a rectangular base and the other newly built circular base.
The reservoir of rectangular reinforced concrete base which is supplied with surface water has a capacity of 520 m3 and is situated at 870 meters. It has a valve house in good condition.
The reservoir is filled in 9 hours at a rate of 18 l / s and VACE an average of 05 hours when not pumping. The average flow of current water consumption estimated by the population of the University is of 28.89 l / s.
According to the survey of the existing sanitary wares Campus peak flow simultaneously should not exceed 18.65 l / s. (See Exhibit D)
The reinforced concrete reservoir recently constructed circular base is in good condition and near constructive start operating. It has a capacity of 150 m3 and will receive water from the tubewell. According to the pumping tests carried out such a pool is filled with water in an average of 02 hours, turning off automatically.
two reservoirs with a total capacity of 670 m3 is sufficient to supply the required daily water allocation of 584 m3. Line
adduction adduction
existing line measures 260 m has a diameter of 6 "PVC material is in some sections and other cast iron is that because of its age is in poor condition. Distribution Networks
The piping system of water network is formed by cast iron pipes and PVC in a disorderly manner. Cast iron pipes are older than 30 years, are corroded and have high leak rates.
existing pipeline length is approximately 3.200 m with diameters between 2 and 4 inches. Valves and sanitary equipment
The fire fighting cocks and valves are inoperative by disuse and age.
The vast majority of gate valves are without handle and sulfated by exposure to the weather. Fixture De
seen, the big problem is wastage in toilets, where major water leaks. In some cases there are also faucets wastage. Neglect is evident in the use and control of this vital element.
estimated waste and leakage in the system are the order of 10 l / s.
The existing pool has a recirculation system that works well for both the ingress of water into the pool by the external network is done once a year
2.2 Definition of Problem
A Central Problem
"Inadequate water quality and insufficient envelope "
The water supply system drinking Enrique Guzmán y Valle University, shows many shortcomings, from capture to distribution.
