INTRODUCTION OF EMASESA

OUR ACTIVITY


100% Public Company

Since 1974 we manage the full urban water cycle. 8/5/2007 it was approved the creation of the current EMASESA, “Empresa Metropolitana de

Abastecimiento y Saneamiento de Aguas de Sevilla, S.A”: nearly four decades providing quality services

OUR SCOPE


111 litres/ person / day. Average daily consumption per person

12 Municipalities supplied. 30 with raw water

368.000 Customers.

1.065.000 Population supplied. 305.000 with raw water

164,4 M€ Turnover

CATCHMENT, TRANSPORT, TREATMENT and SUPPLY


GENERAL SUPPLY SYSTEM

6 Reservoirs (641 Hm3)

3 DWTP (10 m3/s)

3 Hydroelectric Plants. 31,782 Mwh/year

38 Pumping Stations

26 Tanks

3.849 Km Network

103 Hm3 Captured Water Volume

SEWERAGE SYSTEM and WASTEWATER TREATMENT


GENERAL SEWERAGE SYSTEM

6 WWTP 1,800,000 pop. Equivalent

(459.648 m3/day capacity)

1 Composting Plant (8,798 t produced, 25Ha)

22 Wastewater Pumping Stations

41 Rainwater Pumping Stations

3 Storm Water Tanks

2.980 Km of network

The Integral Sanitation Plan: untreated discharges to the river Guadalquivir has been eliminated since 1984

Sevilla has a particular topography, due to this factor, we have a protection plan against floods with 41 rainwater pumping station.

OUR NEEDS ABOUT INSPECTION&MAINTENANCE

INSPECTION AND QUALITY CONTROL OF RESERVOIRS

Inspection and maintenance of power lines and transformation centers

NETWORK CHARACTERISTICS

• 37 km of power lines

• 217 utility poles

• 5 pole-mount Transformers

• Difficult access

CURRENT PROCESS

• Inspection made by workers

(overheating, conservation)

• Use of thermal/thermographic

camera from the ground (less

accurate)

• Working at height

Quality Control of water and sludge in DWTP

CHARACTERISTICS

• 16 clarifiers

• Daily control (sample taking). Samples

taken manually (3 times/day)

• Unproductive time

Línea 1 (5 m3/s)

Línea 2 (5 m3/s)

IAAP (0,3 m3/s)

Depósito nº1 (200.000 m3)


Trat. AfinoPretratamiento

Line 2

Line 1

Laboratories

Water tank 1

Inspection of water tanks

CHARACTERISTICS

• Made of reinforced concrete

• Different geometry

• Emptied every ten years

• Need to check structural problems

SEWER INSPECTION: BIG PIPES


• Ø ≥ 1,80m

• 227 km network

• Medium-High level of water

• Visual Inspection

CURRENT PROCESS

• Team of 5 operators, 3 of them entering the pipeline

• Very bad conditions

• 25km/year inspected, 175m/h inspected.


MAIN HAZARDS


Broken pipesLack of seal in joints Obstacles, sediments

Degradation Roots

SEWER INSPECTION: SMALL PIPES


• Ø < 1,80m

• 2.900 km network

• Low level of water


CURRENT PROCESS

• Terrestrial robot (4x4, 6x6, etc.)


• With camera zoom, image recorder

and illumination.

• Advanced control unit with

integrated software

• Cable length until 1.000m

Pipes repairing, leaks detection, etc.

• Joint sealing systems

• Fissures repairing

• Milling (roots elimination, etc.)

• Detection leaks systems

INSPECTION OF CONFINED SPACES

Control of infrastructures status

• Leaks detection in water ducts (over the

ground, and underground).

• Control of infrastructures status, in general

• Fissures detection

Odour control

• WWTP and composting plant are sources of

odor.

• Use of gas compounds detectors and

electronic noses (perimetral network). Costly

solution.

• Difficult to measure at heigth

• Sometimes it´s not easy to locate the source

of odour
