TREATMENT: What is a WTP- Water treatment plant?It is an installing that collects wastewater from a population or industry,
and after a series of treatments and processes, are cleaned and returns to areceiving stream (river, reservoir or sea).

DIRECTIVE (European Union) 91/271/CEE: Artícle 2
E.h. (equivalent inhabitant): following the EU criteria by which an equivalent inhabitant
produces 60 grams of BOD5 per day, caused by domestic activities.
Related with presence of ORGANIC MATTER in wastewater
Analysis:
BOD: Biochemical Oxygen Demand (mg/l O2)
QOD: Chemical Oxyen Demand (mg/l O2)
TOC: Total Organic Carbon (mg/l)
Pollution Load (g/day) = Concentration (BOD mg/l O2) x Caudal (m3/day)
E-h = Pollution Load / 60 g
Example: Jerez
DBO5 (mg O2/l ): :400
E-h: 272.162

Questions…..?
1. How many Wastewater Treatment Plants are in theGuadalete basin?
2. Are according with the law (Directive European Union)
3. Is the quality of the water in the river in good condition?
4. HOW ARE NOW THE TREATMENT PLANTS?
Let´s see

CONCLUSIONS
1. How many Wastewater Treatment Plants are in theGuadalete basin?There are sufficient WTP but their operative were not correctlyperforming.
2. Are they according with the legislation(Directive European
Union)No, and currently most of the Plants are in a worse situation than yearsago
3. Is the quality of the water in the river in good condition?No, and probably in a worse situation than 2004
Is Guadalete Basin according to Water
Framework Directive for 2015?
What is the solution?
