WOP: Aguas Santafesinas - Aigües del Prat S.A.
April 15, 2014
The WOP comes from the invitation that Aguas Santafesinas S.A. received to participate in a Regional Workshop for capacity building about water safety plans held in November of 2012 in Quito (Ecuador), financed by UN-Habitat/GWOPA, with the collaboration of IWA and Cap-Net.
Thereafter, Aguas Santafesinas (ASSA) with the support of AEOPAS, the Spanish Association of Public Water Utilities and WOP-LAC, was put in contact with the Spanish utility Aigües del Prat S.A. that operates a reverse osmosis plant, recognized by its excellent management, similar to the ASSA one.
The WOP contributed to develop the ASSA own water safety plan, and specifically for the town of Firmat in Argentina, that in summertime suffers from the lack of water to supply the population. The potabilisation of the aquifer of the area is the main issue.

Water Security Plans
The objective of this WOP is to contribute to the Development of the Water Safety Plan that the company Aguas Santafesinas SA tries to develop and implement for its Reverse Osmosis Plant in the City of Firmat, Province of Santa Fe, Argentina.
Why develop a Water Safety Plan (WSP)?
Through the adoption of a WSP, an operator can improve the efficiency and effectiveness of its structure and ensure the supply of water in adequate quantities and quality. Through a framework of risk assessment and management that is complete and considers all stages, from catchment to consumption, operators acquire the tools to identify and address those priorities that may affect the delivery of the service. A (WSP) is the most effective instrument to ensure that water meets the minimum health requirements, as well as other essential parameters to classify water as potable. In order to protect human health and ensure the availability of uncontaminated water, a PSA has as its main objectives the minimization of contamination at the source level, the reduction or elimination of pollutants through appropriate treatment processes, and contamination risk prevention during the distribution phase. The advantage of a WSP is that it can be applied to any type of water supply system, regardless of its size or complexity.
General objectives of the WOP:
- Contribute to the Preparation of the Water Safety Plan (WSP)
- Establish professional relationships with specialists in the treatment of water by reverse osmosis.
- Acquire knowledge about methodologies and ways of working in the different production processes.
- Acquire knowledge on ways of managing human and economic resources.
Specific objectives of the WOP:
- Basin protection
- Quality control of collected and supplied water
- POI operational control
- Knowledge of used technology
- Energy recovery - Rejection
- Maintenance and control of networks
- Relationship with the user
- Expand knowledge (reagents, supplies, suppliers, etc.)
What types of activities were carried out to help develop operator capacity?
Describe WOPs activities
First visit: Aguas Santafesinas SA (Santa Fe, Argentina) to Aigües del Prat S.A. (Barcelona, España).
Date: July 2014
- Purpose of the visit: i) Be able to analyze the points identified in the communications carried out between the companies, ii) Identify improvements to be implemented in the operation and maintenance of Firmat's POI, with the purpose of finalizing the PSA based on good management practices.
- Morning and afternoon work with participatory conferences on the different topics, with contribution of ideas in both directions, presentation sessions and participation of specific topics, which previously in the program proposal had been identified as interesting.
- Participation of all departments of the company involved in any of the issues
- Some of the topics discussed were:
*Operation and maintenance of production stations
*Automated facilities management (remote control)
*Quality control of the supplied water
*Maintenance of the drinking water and sewerage network (materials, installation, repair ...)
*Network sectorization and leak detection systems.
*Geographic Information System (GIS)
*Teamwork between various areas of the company
*Supply Management without the need for 24-hour staff
*Administrative management and communication with subscribers
*Tariff pricing system
*Visit to drinking water treatment station (ETAP) and wastewater (EBAR)
*Visit to installation works of potable and non-potable water networks
*Visit to APSA laboratory
*Institutional visit to the municipality of Prat de Llobregat
*Presentation of Energy Recovery System (Turbocharger)
*Presentation of monitoring and remote control system
Second visit: Aigües del Prat S.A. (Barcelona, España) to Aguas Santafesinas SA (Santa Fe, Argentina).
Date: April 2017
- Purpose of the visit: be able to observe in situ the operation of the Reverse Osmosis Plant of the City of Firmat, the technology used, the maintenance procedures, etc., in order to be able to make suggestions for improvement in the operation and maintenance of the POI, that guarantee an adequate design and implementation of the WSP.
- Form of work similar to that carried out in Prat de Llobregat
*Knowledge of the problem "in situ"
*Participation of all departments of the company
*Involvement of the company's management
*Exchange of ideas and proposals for improvement
*Planning of the work to be done and calendar of action
- Main anomalies detected in the municipality of Firmat:
*Problems with the ETAP filtration system
*Lack of continued water supply
*Quality problems (mainly high levels of Arsenic, turbidity...)
*Lack of automation of the facilities (a lot of manual control with the need for personnel 24 hours/day)
*Lack of knowledge of the distribution network.
*Ignorance of the actual performance of the network (actual consumption of subscribers and water supplied to the network)
*Numerous breakdowns and major water losses
*Single network without sectorization
*Poor pressure at certain points in the network
*Billing according to the size of the housing, regardless of actual consumption (in the few houses with a meter, average consumption of more than 300 l / room per day)
*Single price of m3 regardless of consumption
*Bill partially subsidized by the Provincial State
*Specific staff for each task and not very versatile
*Very manual and little automated systems that implies continuous presence of personnel
WATER SAFETY PLAN DESIGN:
Once the first visit of ASSA to Aigües del Prat S.A. was finished, the team designated by ASSA carried out the design of its Water Safety Plan, using the knowledge incorporated in the technical visit and the recommendations received from the mentor company.
The deadline for the preparation of the Draft of the WSP was 120 days.
Describe the overall results
1) CONTROL OF WATER VOLUMES PRODUCED AND DISTRIBUTED
• The installation of flow meters / meters at the production stations.
• The control of the volumes used by the subscribers.
• Network performance.
• Network sectorization for leak control.
2) KNOWLEDGE OF THE GROWING RATES APPLIED IN PRAT DE LLOBREGAT
• APSA average bill: € 39 bimonthly (3 people - 95 lt /room/day)
• Average ASSA bill: € 30 bimonthly (4 people - 200 lt /room/ day)
• Invoice subsidized by the Pcial State. approx. € 10 - APSA would be € 145 bim.
3) AUTOMATED OPERATING SYSTEMS
• Automatic cleaning three-layer filters
• Remote control of automatic warnings for various alarms.
4) SAVING PRODUCTION COSTS
• Increase in performance reduces costs (energy, reagents, ...)
• Work staff
• Teamwork between different areas.
• Multidisciplinary staff
5) METER INSTALLATION:
• 2014: 148 meters
• 2015 (July): 317 meters - increase of 10.5% measured park
6) WATER NOT ACCOUNTED
Two leak detection campaigns were carried out:
• July 2014: 20 km route - Result: 2.5 leaks / km; approx. 8.4 m³ / h
• October 2014: 14 km route - Result: 4.2 leaks / km; approx. 12.5 m³ / h
• Two campaigns: 20.9 m³ / h = 183,125 m³ / year (8.5% of the annual volume delivered)
• The total cost per m3 produced is approx .: 0.5 €
• Recovery of € 91,500 / year
• Preview 3rd Fredickson Neighborhood Campaign
7) NETWORK SECTORIZATION
• Existence of 7 pitometric cameras, out of service. In July 2014, 1 was put into operation, planned at the end of 2015 to put another one, to start monitoring the night consumption for leak detection.
