Are being installed nearly 18 miles of pipelines.
The works could be completed in May. |
Water Councilman City of Lorca, Melchor Morales, announced today the works are being completed in the hamlet of Riverside, in watering places, which will allow more than 1,500 neighbors who today do not have with potable water network, have this service.
Morales is anticipated that the work being carried out have a total investment of EUR 796,836.33, and that work without no setbacks occur, could be completed next May.
Morales has detailed "With this investment we are solving a very serious problem for the residents of this area.
A few months ago the City Council we are committed to resolve this situation as early as the month of February works were launched.
Our goal, marking, by the Mayor, is that citizens of the Bank, have the water service as soon as possible.
We will fix also significant deficiencies in providing the rest of the council, given the distance and altitude houses have regard to the municipal water supply network.
With this work we provide the necessary water infrastructure to supply potable water to this area, with guarantees of flow, pressure and hygienic-sanitary conditions under public health legislation in force for normal water supply to homes existing "
This work includes a requirement of drinking water in the area for about 500 homes, with a population of about 1,500 inhabitants and a flow demand for fire supply of 2,000 liters / minute.
The distribution network will be supplied with water from the new distribution networks López Country kernel.
The works include the installation of a total length of 17,724 meters driving drinking water in different diameters from 200 to 90 mm and of different materials from ductile iron, provided with exterior surface anticorrosive and high density polyethylene, with their corresponding elements cutting, suckers and bottom outlets, as well as for additional civil works consisting of trenching, backfilling with sand to protect the pipe and compacted properly selected material.
Just as the structures, necessary for access to different hydraulic unique elements to be installed.
A trenchless work: less noise, faster and safer
For the execution of works, are using trenchless technology equipment for the installation of pipelines, potable water, high density polyethylene.
In these new systems, we can distinguish between those that allow control of management and those without.
The choice of one technique or another depends on factors such as the precision required in the route of the pipeline, the proximity of other services, length of installation, soil type, depth, etc.
In the works of drinking water supply Spot The Riverside, County of watering places, is being used directional drilling system.
This type of work is done with a specific drilling machine, small size, which can work from a tasting practiced in the field, or from the same land area, in this case without any need for excavation.
The drilling is done by pushing, sometimes combined with rotation, a head fitted with a bar equipped with a directional emitter position by radio, by what is known at all times where they are located, may vary drilling trajectory, if there is any deviation.
The drill head should come out tasting (or surface) and that once the drilling is necessary to remove the drill head and instead mounted a cone reamer to enlarge the diameter of the hole.
At the end of the cone joins the pipe you want to install (the diameter of the reamer should be appropriate to the diameter of the pipe).
By reversing the direction of travel of the machine, the reamer enlarges the hole drilled, leaving the polyethylene pipe installed.
The main advantages of this system are:
A) There is no need to trench, just a taste of output and input any other case, this translates into:
1. To have more security for workers, pedestrians, vehicles and homes.
2. Not cause disturbances to the public.
3. Minimal or no disruption to traffic.
4. There is less risk of affecting other underground utilities.
B) This system significantly shortens the time of execution of work, this saving may be two to three times compared to the usual work.
C) The operation of the machine does not require excessive labor, sometimes only two operators.
D) In a workday can install up to 200 to 300 meters of driving, depending on the conditions of the terrain.
F) All of this leads, in addition to environmental and social benefits, to have a lower cost of execution of works.
By failing to conduct trenching, avoiding the typical drawbacks of traditional technology.
Trenchless technology, which is being used in the execution of works for water supply the place of Riverside, County of watering places, is offered as an alternative advantageous compared to traditional methods when you want to skip the series aforementioned drawbacks.
Experience in conducting this type of work and performance of mechanical equipment can deal with the burial of the pipes without the need for ditches.
