Description
General Objective
Increase sanitation coverage (collection, conduction and treatment of wastewater) in Hondo River sub-basin, to eliminate environmental and public health risks, increase the supply of drinking water and treated wastewater for the Municipality and reduce greenhouse gases.
Specific objectives
• Collect a minimum of 95% of the waste water that is currently discharged in the river, through the construction and maintenance of 13,088 linear meters of water pipes.
• Design, build, operate and maintain four wastewater treatment plants (WWTP) for 20 years and rehabilitate two other existing ones, to treat at least 463 liters per second, equivalent to 40% of the wastewater that will be discharged to them.
• Distribute at least 398 lps of treated water through the construction and maintenance of 6 km of purple line to 3 industrial parks in Naucalpan for reuse and exchange of drinking water for treated water for public and industrial uses.
• Fully comply with current environmental legislation for wastewater discharges (NOM-001 and 003-SEMARNAT) as well as the Environmental and Social Performance Standards of the IFC (World Bank).
• Preserve water aquifers for human consumption for the population.
• Mitigate methane and other greenhouse gases from wastewater.
Project Components:
Component 1.- Water Pipes
- Collection, conduction and removal of 1,318 lps of wastewater.
- Identification of more than 500 domestic and industrial discharge points.
- Construction and maintenance of 12 km of collectors to "El Cristo Regulator Vessel", without displacement of irregular settlements.
Component 2.- Waste Water Treatment Plants
- Based on: i) availability of land, ii) amount of residual discharges and iii) demand for treated water, it was determined to implement a decentralized system of 4 WWTPs.
- 6 technologies were comparatively analyzed, based on innovation, energy-chemical consumption and applicability-experience in Mexico
- It was determined to complete the Terms of Reference (ToR) based on goals and parameters allowing bidders to propose their best technological solutions.
- To obtain authorizations from the Mexican Federal Government, a theoretical model was developed using extended aeration technology (average scenario)
Financing structuring
The Project is structured as a federal Public-Private Partnership (PPP):
• BOT (build–operate–transfer) in a Public-Private Partnership (PPP).
• OAPAS concessions through bidding to a private company the design, construction, operation and maintenance of the Project for 20 years.
• Contract: 20 years of operation + 2 of construction (22 years in total). At the end of the Contract, the infrastructure is transferred to OAPAS.
• It is responsibility of the private company to provide the corresponding maintenance during this period.
Governance
- The winner of the tender must create a Specific Purpose Vehicle (SPV)
- The Project is operated by a Trust of Administration and payment source, which makes transparent the incomes and expenses , and establishes the priority order of payments.
- It is contemplated the hiring of an External Supervisory Project Manager for all the phases and duration of the Project.
Preliminary CAPEX: USD 55 Million
Mexico City is experiencing an unprecedented water crisis. The overexploitation of aquifers and the impacts of drought and climate change have significantly reduced the amount of water available for human consumption. Furthermore, water pollution is a considerable challenge that affects both human health and the environment.
Only in the area of direct influence of the Project, it is estimated that the population affected by lack of sanitation is a total of 112,785 people: 45% are related to respiratory diseases, 4% to diarrhea and parasites, 47% to dermatitis and 4% to conjunctivitis.
SDG 6 seeks to ensure the availability and sustainable management of water and sanitation for all.
The Project is aligned with this Objective at the local level since it will allow the most vulnerable population of the Municipality access to drinking water constantly and at an affordable price.
Water quality will also be improved, reducing pollution and increasing recycling and safe reuse; providing equitable access to sanitation and hygiene services.
These actions will increase the efficient use of water resources, ensuring the sustainability of water extraction and supply.
Additionally, it contributes to SDG 3: “Good health and well being”, in relation to substantially reducing the number of deaths and illnesses from hazardous water pollution and contamination.
The Project considers a blending finance scheme for investment, which seeks to break the vicious circle of: lack of resources = poor service = inability to create infrastructure. Since it allows generating the required infrastructure without investment for the Municipality.
Once the Project comes into operation, it generates savings and incomes for the Municipality that allows it to face the financial commitments of the Project, such as: greater consumption of drinking and treated water; release of aquifer extractions; savings on illnesses/disabilities; and increase in capital gains.
This financial scheme with private participation generates more value for money than if it were implemented through the public traditional channel. It also allows accelerate SDG implementation
