Reclaimed water in Callosa de Segura

Callosa de Segura waste water treatment plant

Waste water source

Wastewater coming from 5 municipalities into the wastewater treatment plant of Callosa de Segura. GLOBAL OMNIUM MEDIO AMBIENTE is the company that is in charge of the WWTP.

Distribution System

The water is pumped from the WWTP to the fields. Treatments are carried out to prevent algae and microbiological growth.

Farming system

The crop grown are fruit trees (lemon and orange – citrus), almond, arable crops, vegetables (lettuce, artichoke, tomato, ...)

Waste water treatment description

Nutrient removal : Prolongued aeration
Pesticide removal : none
Disinfection : Chlorination
Suspended solids removal : Coagulation
Other :


On a daily basis 8,644 m³ is treated, which correlates to 61,199 person equivalents. The Irrigator Community uses 1.89 hm³ of reclaimed water on a yearly basis.

Extent of the agricultural beneficiaries

A total of 2,960 hectares is irrigated with reclaimed water, divided over 1,654 farmers.


Pipes and pumping station are subsidized by the regional Government. Operational and maintenance costs are 0.092 €/m³ which are paid by the Irrigators Community. Every Farmer in each irrigators community must pay a fee. The fee normally is based on 2 concepts:

  • a contribution to water use services (dams, state canals, etc.) from public domain which is collected by irrigators communities and later paid back to the State
  • the inside costs of irrigators communities (personal cost, energy, facilities, etc)

Type of agreement

There is an agreement with River Basin Authority of Segura River to use reclaimed water.
