MARTA DUTSCHMANN DA SILVA GOMES - WASE COMPANY

Dear Davis Augusthy,

Today commonly we find the question of the most appropriate material to put in a water network, and the scientific and technical knowledge on this topic differs from manufacturer to manufacturer. Each one tries to explain and expose the advantages of their materials to be applied in networks of clean water. But this choice has to do with different criteria depending on the type of facility, in which diameter is to be used, the storage in site work, the installation costs, and in your case the criterion most influential is the material which ensures the most quality of water supplied.

The  WASE company   (http://wase.pt/), based in Portugal, has an innovative service decision support consultancy in the area of choice of the most appropriate type of pipe depending of the situation. We deal with these issues professionally, based on two software’s: one is the study of each solution installation costs- The INVESTPIPE software (is under development for diameters up to 200), and another software- the WISED- with criteria insertion, and pondering for each one, it gives robust and reliable results for the final decision. Therefore you will take a decision of witch material to apply in your network, based on something concrete, reliable and focused in your special case. The choice will be always yours, but conscientiously and according to the criteria that have more weight for you! 

I see you have a choice to make for your project and many doubts are coming, well, we can help you, based on your decision criteria’s (water quality transported, the investment cost, and reliability of the material, durability and versatility of the solution). The difference in the degree of importance of these criteria is not linear, that is, the criterion that carries more weight for you is the transported water quality, and it will undoubtedly be the criterion with more weight. The weight of this criterion comparing to others, such as the investment costs, the durability of the material, its resistance, facility of installation, reliability when in operation, etc. will all have different weights in your choice, these differences are not linear and equal. The WISED software eliminates all the errors that multicriteria matrices have. 

Feel free to contact me at  +351 969 034 092  or   marta.gomes@wase.pt . I leave you below an excerpt in English of our website so you can have a little more information about the software support for multi-criteria decision. (I've attached my business card also).

To see an example of a WISED report (demonstration) for a choice of material for a DN110 between ductile iron pipes, PVC and PEAD, please contact me to my email, I can give you a brief pdf with the graphics and weighted I used for this specific example.

SOFTWARES: Evaluating options considering multiple benefits, costs and risks is a challenge that the management of water bodies encounter in day-to-day. Through WISED and INVESTPIPE application, we can support decision-making processes in a collaborative, transparent and objective. WASE promotes this application as the main tool in decision-making materials of a supply system / distribution of water, however, it's a software applicable in other areas, already proven and international recognition, such as procedural proposals in supply competition in assessment strategies, staff performance and investment projects. With WISED, processes are transparent and objective assessments. The main advantages to the use of this application are:
