The technical data collection is fundamental in order to have a correct designing of the water treatment plant. If the data collected on site or received from the client is incomplete or unclear, then the following problems can occur:

  • Significant increase of the time necessary for the final draw up of the plant.
  • More confusion and less precision during the designing phase.
  • An increased amount of visits on-site to collect the right data.

Furthermore, it happens often that the data received turns into a drawing of the plant that does not fulfill the complete requirements of the client. It is important to highlight that the time lost in correcting this mistakes in essential, and sometimes determinating, in order to respect the times agreed for the realization of the plant.



To avoid the delays and problems listed above, we provide next a  brief description of the data needed for the correct designing of an Idrosistem water treatment plant:

  1. Type of industry: for example, textile, iron and steel, food, spunlace, etc. This information is necessary to understand the production process used by the client.
  2. Type of discharge: contaminating substances present in the water to be treated (pigments, color, acids, metals).
  3. Water flow and volume: for the continuous and temporary discharge, we need to know the total flow (m³/h), the working time (hour/days) and the frequency (weekly, daily, etc).
  4. Pollution load: concentration of the contaminating substances in the water. The clients must be able to provide at least some basic information about the raw material and products used in their production process (for example: main ingredient, chemical composition, toxicity, etc.). This is usually the information reported on the commercial labels of the products.
  5. Existing collection systems: if we have information about the existing structure, we can take advantage of the systems already present on site by making some improvements with the correct adaptation of our plant.
  6. Local Legislation for the wastewater discharge: this is fundamental when designing the plant because we must know the parameters that must be respected according to the type of wastewater and the final destination of it (river, sea, sewer, ect.).
  7. Laboratory analysis: results of the laboratory analysis already made by the client, indicating the chemical and bacterial load of the wastewater. We usually provide a list of the parameters we need.
  8. Technical reports: chemical or hydraulic reports already made by the client or by some external advisor.
  9. Space available for the water treatment plant: this includes the space available for the placing of the plant (m²), dimensions, location (indoors, outdoors), access with heavy machinery, distance from the place of disposal (river, sewer), and altitude of the site (sea level).
  10. Civil works and excavations: we must know the disposition/refusal of the client to perform civil works on the site for commercial, ecological or economical reasons, so we can offer the best solution (see Glassed steel tanks on our page “Services”).
  11. Water samples: collected from the wastewater or from the raw water.
  12. Intentions of the client: for example, sometimes the client wishes to start with a simple plant with the possibility of improvement in the future.
