The practice consisted in the purification and innovative refinement of the urban wastewate for agriculture reuse. In the summer 2009, the purified and refined water was in fact distributed for free to farmers for irrigation purposes.
The project for the application of the practice was drawn up on the initiative of the municipality of Ostuni and financed by the region of Apulia in the context of CE FESR funds for the period 1994-1999. The practice was born following the water crisis due to prolonged drought, that took place between mid-1980s and early 1990s, that caused a reduction of the availability of water collected in reservoirs and a high increasing in the use of groundwater. Consequently, the need to find new sources of water for agricultural uses strongly emerged and the reuse of reclaimed wastewater aimed to contribute to this need.
The development of the practice was facilitated also by the involvement of the local community with the Environmental Forum organized within the Agenda 21 activities. The Forum was managed in the form of a participatory platform and one of the main priorities identified for the development of the local territory was the conservation of the secular olive trees.|

The practice was considered as 'best' mainly on the basis of the analysis of its efficacy. The agricultural reuse of the municipal reclaimed wastewater, although applied at a small scale and only for one year, may be considered potentially efficient because it increased the productivity of olive trees and responded to the need to provide an irrigation source which could be an alternative to water outflow from private wells. Moreover, the availability of the reclaimed wastewater for irrigation stimulated some farmers to grow horticultural crops, thus, potentially increasing the farming income.
The economic efficiency and the effectiveness of the practice were not evaluated since it was applied for one single year. However, the municipality of Ostuni aims to reiterate the experience in the next years, but under payment request to farmers who whish to have access to the wastewater.|

Үндсэн үйл ажиллагааны товч танилцуулга, зорилтуудаар

Farmers' Unions collaborated with the municipality of Ostuni to promote the use of purified urban wastewater and to provide technical assistance to farmers for growing irrigated crops, as alternative to olive trees, that are not possible without irrigation.|
Distribution of purified wastewater to farmers growing olive trees (the majority of farmers in the area have olive trees).
The municipality of Ostuni  designed a municipal wastewater reuse systems for irrigation uses to be connected to the existing purification structure.
For this purpose, the Apulia regional government funded the realization of the needed infractrastures through the FESR 94-99. |Several monitoring acitivities were made to ensure the adequate funtioning of the wastewater reuse systems. The last monitoring in 2007.|In the summer 2009, the reclaimed wasterwater was provided for free through the wastewater reuse system to the farmers who have required it.

Технологийн техникийн нөхцөл ба товч тодорхойлолт

The urban wastewater of the municipality of Ostuni is submitted to a biological purification process and to a subsequent refinement. The purified and refined wastewater is then pumped from an open stocking basin toward the irrigation distribution grilles. The whole purification, refinement and distribution system was constructed taking into account the size of the potential irrigated area.|
The wastewater reuse system has an operative capacity of 6000 mc per day with a maximum flow of 100 L per second. The stocking basin for the purified and refined wastewater contains up to 1000 mc.  
The quality of the purified wastewater is high respecting all the legal requirements according to the table 4 of the appendix 5 of the D.L. n. 152/1999.

The conservation of the secolar olive trees is a priority for the local community since they associate to them a strong element of identity of their territory and one of the most important touristic attractive factors. Local institutions have interest to promote strategies for the preservation of this heritage and also for its valorization to create economic benefits to the territory (multifunctionality). Farmers attribute to olive trees a major economic value, not primarily associated with productivity, but mainly for the increased opportunities created by the access to funds finalized to the conservation of secolar olive trees and by an improved commercial allocation of their products due the promotion of the touristic flow.

Development of tourist activities related to the secular olive trees leading to economic benefits to the sourrounding area.
The success of the practice (even if applied for one year) could stimulate the wasterwater reuse for agricultural purposes in other areas of the Apulia Region already equipped with the purification and refinement infrastructures but never used so far.

Биологийн төрөл зүйл, уур амьсгалын өөрчлөлтийн нөлөөлөл

Шалтгааныг тайлбарлана уу:

The increased water availability has preserved the secular olive trees from the disappearance.
The duration of the practice has been too short so far to have impacts on climate change mitigation.
Increased adaptation to drought of the farming systems through the reclaimed wastewater availability for irrigation.
The positive collaboration and co-learning developed between the municipality of Ostuni and the Apulia Water Association was one of the main ingredients for the success of the practice and it could be important for future actions to increase the community capacity to adapt to environmental changes
