Outfalls, Catchments, Aqueducts:

Soldadura de PEAD para Emisario Submarino

When installing emissaries, catchments and underwater aqueducts required pipe high density polyethylene (HDPE) is the best solution compared to other alternatives such as steel, cast iron, fiberglass or concrete when submerged refers facilities.

A world of benefits:

• Lower frictional losses.
• Easy to transport.
• It is not attacked by corrosion (does not require cathodic protection).
• Absence of sludge and scale within.
• Long life (over 60 years).
• Lower costs of procurement and installation.
• Better behavior before earthquakes.
• Lower maintenance costs.
• Elasticity and flexibility to adapt to the topography.
• Facilities for installation in long stretches Subsea Pipelines.

The implementation of these projects require professionalism. Be sure to include the following aspects:

• Preliminary Evaluation
  • Find customer needs and visualization of technical solutions.
  • Pre-technical design variables: length, diameter, depth, pumping, among others.
  • Eval of the limitations of the Project.
• Study
  • Bathymetric study.
  • Pipe welding.
  • Topographical area land-water transition.
  • Oceanographic: winds, currents, tides and waves.
  • Sampling the ocean floor.
  • Environmental and social Impact.
• Route Selection
  • Submarine review to verify site features, soil conditions, slope, location of obstacles, environmental restrictions, among others.
    ◦Identify and selection of the most suitable route by applying technical, economic and environmental criteria.
• Permitting
  • Environmental issues.
  • Port captaincy.
• Pipeline Design
  • Hydraulic design: Calculation of length, diameter and pumping requirement.
  • Structural design: Calculation of thickness of pipe, concrete counterweights and burial.
  • Dilution calculation of the effluent to determine diffuser design and location of emissaries.
  • Intake filter calculation for water catchment and diffusers for outfalls.
  • Estimated cost of implementation.
• Selection and evaluation of suppliers, request for quotations, procurement of goods and services required for execution.
• Execution of the construction processes adapted to the specific characteristics of the town.
• Application Process Project Management: Start, Planning, Implementation, Monitoring and Closing
• Inspection of coastal marine works on the construction process in order to ensure that it is conducted in accordance with the plans, standards and specifications approved.

Using underwater pipeline in High Density Polyethylene HDPE for building Outfalls, catchments and Water Supply is a solution long-lasting and more economical.
