International Best Practices

for Public Private Partnership

Industrial Wastewater

ManagementBy

Dr. Avigit Dagupta

Team Leader

Critical Need

Centralized Industrial Wastewater Treatment Plants (IWTP) with reuse of treated effluent are critical to:

Reduce pollution

Conserve water and other resources

Reduce operating cost of industries

Challenges of centralized

IWTPs

Capital cost for construction

Operation & Maintenance costs

Who will own and operate the IWTP ?

Ensure that industries will use the IWTP

Technical design issues

Successful Approaches

Phased construction of the IWTP design capacity using modular technologies – reduces initial capital cost

Combined domestic and industrial wastewater treatment plant

Private-Public Partnership

Public Private Partnerships

Includes financing package with:

◦ Grant from government and/or donor (20-30%)

◦ Investment by industries using the IWTP (15-25%)

◦ Private investors (20-30%)

◦ Soft loans (40-50%)

Advantages of PPP Sharing of cost by industry stakeholders

Cost sharing attractive to potential investors and

loan agencies

Stakeholder ownership in IWTP

◦ Incentive to use the IWTP by industry stakeholders

◦ Incentive to discharge only proper waste to the IWTP

◦ Better management = better compliance

◦ Cost savings for industries

◦ Sustainable financial and operational model

Examples of Central IWTPsItem Description

Number of IWTPs

as of 2005

88

Capacity 0.5 - 25 MLD

Types of

Industries

Food, chemical, textiles, leather,

paper, steel, pharmaceutical,

petroleum, power, plastics, metal

finishing, etc.

Use of Treated

Effluent

- Discharge to rivers

- Reuse for agriculture

- Reuse for industry

Capital cost $0.5 M - $15 M

Financing Govt. + Industries + Loan

Year of

construction

Since 1994

Example in Jordan

Current Condition

With PPP Approach

Distance to disposal facility

70 km <10 km

Cost of wastewater disposal

JD 18,000/y JD 9000/y

Investment in WWTP

JD 0 JD 5000

Return on Investment

JD 0 JD 500/y

Net Cost Savings

JD 0 JD 4500 Yr 1JD 9000 Yr 2

Recommendations

Industry commitment to pollution prevention

Increase industry-government and donor dialogue

and cooperation

Improving industry water/energy cost savings and

pollution prevention

Forward looking, creative sustainable approaches

to financing IWTPs through the PPP model

Thank you for your attention

Water Requirement: 800 m3 per day

Agricultural Use: On-Site

Industrial Use: Steel Plants

10 Steel Plants in Muwaggar and Sahab located within 10 km radius

Water Required for Cooling

Steel plants pay 1-2 JD per m3

Cost of transportation 1 JD per m3

Not feasible unless managed properly, large carbon footprint from transport 20 m3 per

truck load.

Base Course & Street Construction

Water required for base coarse mixing and street construction

10% Volume from Water

30,000 m2 of Street Construction per day

New roads are being constructed in the area

Bio Gas Production

Anaerobic Digestion Co-Substrate

Recommendation

Jordan underperforming when using grey water

Identify plot of land for animal fodder growth or potentially biofuel plant.

Community support projects in agriculture

Legislation and building codes
