GENERAL USES OF RECLAIMED WATER.

Today, around 80% of all wastewater is discharged

untreated into rivers, lakes and oceans.

980 MMm3/d = 3,8 Bpeople

Agricultural irrigation is the biggest user of recycled wastewaters.• 60% Californian. • 41% Japan. • 15% Tunisia.

The most common uses:• Irrigation for crops and pasture.• irrigation for silviculture (forestry).• irrigation for landscapes.


RECLAIMED WATER IN AGRICULTURE. MAIN USES

1. Reliable source of supply.2. Reduce Resources Utilization/Stress.3. High Content of Nutrients (N,P)4. Protection of land5. Protection of ground water6. Protection of surface water.7. Community Amenity.8. Increase Investment9. Energy savings. 10. Affordable cost.


RECLAIMED WATER IN AGRICULTURE. ADVANTAGES.

BRINE + RECLAIMED WATER BLENDING.

A. Difficult to approve for:1. Drinking.2. Some domestic purposes.3. Recreational applications.4. Direct application to Vegetables and Fruits.

B. Contamination with:1. Pathogens,2. Toxic Chemicals.3. Heavy Metals4. Antibiotics.5. New micro pollutants.

C. Unpleasant Odors.D. Regular irrigation system back up.E. Decrease in soil quality (accumulation of metal / acidification)F. Sprinkler based systems high demanded management

RECLAIMED WATER TEHCNOLOGICAL REALITY.


ISTP ATOTONILCO 4 MILLIONS M3/D.

SOLUTION:

PPP for Largest Instalation worldwide built in a single stage.

(60% Mexico City Sewage).

It will benefit to 700,000 inhabitants of the Mezquital Valley

(300,000 of them in risk areas)

3rd largest Waste Water Treatment plant by capacity:

1º Stickney Water Reclamation Plant (Chicago):

4,5Mm3/d

2º Dear Island Sewage Treatment Plant (Boston):

3,7Mm3/d

3º PTAR Atotonilco (México): 3Mm3/d

PROJECT BACKGROUND:

The irrigation for the Mezquital Valley with the wastewater of the

Mexican Valley, without any treatment, had been causing risks to

the Public Health, deterioration of the soil, phreatic stratum

pollution and decrease of the quality conditions of its inhabitants.



During 2013 pilot plant testing for:1. Harmless use of treated water for crops.2. Efficiency impact on crops. Soil impact.3. Efficiency with different irrigation technologies.

Main Crops Irrigated :

Corn,

Beans,

Tomato,

Onion,

Olive tree,

Peach,

Alfalfa,

Green chile

Total Irrigated Area = 90,000 hectars = 180,000 Footbal pitchs = 900 Km2Under development potential use in more profitable crops

1. Cooling Processes: To control biological regrowth and mineral buildup. 2. Water Boilers: Pre-Treated. To control mineral buildup.3. High-Tech Manufacturing. Pre-Treated. Semiconductor and microchips.4. Reclaimed water can be used in high-tech manufacturing such as the

semiconductor5. Prepared Food Manufacturing6. Fire protection.


RECLAIMED WATER IN INDUSTRY. MAIN USES.

A business can directly reuse wastewater that is clean enough for the purpose for which it is

being reused.

Within Business: 1. Optimization of resources. 2. Increasing water availability.3. Increasing productivity/water input,4. Energy savings. 5. Cost treatment savings.6. Lowering waste water discharge7. Reducing processing cost


RECLAIMED WATER IN INDUSTRY. ADVANTAGES.

Industrial water usage dropped from the 1950s to 2015 by 36 %

Between Business: 1. Economy of Scale,2. Sharing the management of

utilities, 3. Sharing ancillary services4. Sizeable Biogas Production

facilities.5. Distance as key factor.6. Exchange of by-products

1. High knowledge about quality of water for reuse.2. Less technology performance data from installations3. High Investment requirements.4. Greater need for rapid return on investment 5. Proprietary nature of industrial corporations 6. High level of trust.7. Optimization of Operation.

WHAT REUSE. LEGAL FRAMEWORK


WATER RESUSE IN KSA.

• Only 12% of the total municipal wastewater generated currently being reused.

• 100 percent reuse of wastewater from cities with 5,000 inhabitants or more by 2030 (95% Population covered).

• Wastewater treatment and reuse sector is currently valued at a market size of $5.5 billion (Capex).

Desalinated vs Reclaimed = 1.95 Hals (54 cUSD)/m3 vs 89 Hals (24 cUSD)/m3
