Request for Proposals: Implementation of Grey Water Treatment System (GWTS) and Rehabilitation of Sanitary Facilities in Harir District

1. Introduction to BORDA:

Bremen Overseas Research and Development Association [BORDA]

People. Innovating. Sanitation.

Since 1977, the Bremen Overseas Research and Development Association [BORDA], a non-profit civil society expert organization headquartered in Bremen, Germany, has provided innovative, demand-oriented support in urban development and in the provision of essential public services. The country office, BORDA-KRI, contributes to improving the living conditions of socially disadvantaged groups by creating and facilitating access to basic needs services such as sanitation, management of urban waters, and water provision while maintaining a safe environment.

2. Project Description:

Innovative and environmentally friendly, Greywater Treatment Systems (GWTS) are designed to efficiently manage wastewater at a local level. GWTS are modular systems that provide treatment capabilities closer to the source of wastewater generation than traditional centralized systems. These systems integrate multiple treatment processes such as filtration, anaerobic digestion, aerobic treatment, and sedimentation. GWTS offers several benefits:

Water Conservation: By recycling greywater (from sinks, showers, and washing machines), these systems reduce the demand for fresh potable water, which is crucial in areas facing water scarcity.

Cost Savings: Reducing the amount of freshwater used for non-potable purposes can lower water bills. Additionally, treating and reusing greywater can extend the lifespan of septic systems and municipal wastewater treatment facilities.

Environmental Protection: Recycling greywater helps reduce the volume of wastewater entering sewage systems, which can decrease the risk of overflows and reduce the environmental impact on local water bodies.

Enhanced Plant Growth: Greywater can be used for irrigation, providing plants with nutrients found in soaps and detergents (if used properly), which can promote healthier and more robust plant growth.

Energy Savings: Treating and transporting greywater uses less energy compared to treating and transporting all wastewater. This can contribute to overall energy savings and reduce greenhouse gas emissions.

Reduction in Pollution: Properly treated greywater has fewer contaminants compared to raw sewage, reducing the risk of pollution and contamination in local water sources.

Resilience: In areas prone to drought or water shortages, greywater systems can provide a supplementary water source, helping to maintain some level of water use and functionality during tough times.

Educational Value: Implementing greywater systems can raise awareness about water conservation and sustainability practices, encouraging more environmentally conscious behavior.

The Grey Water Treatment System (GWTS) to be implemented in Harir is designed to efficiently manage local wastewater treatment needs in a sustainable manner. This system will be modular, integrating sedimentation, anaerobic digestion, aerobic treatment, and filtration processes within a unit. The treated wastewater from the GWTS will be utilized for irrigating trees in a public garden, contributing to the enhancement of green spaces in the community. The project will also include the rehabilitation of a drip irrigation system to ensure efficient water usage.

3. Objectives:

• Grey Water Treatment System:

  Implement a GWTS system in the Harir district to improve wastewater management and reduce environmental impacts. The treated wastewater will be used to irrigate the trees of the Harir public park and will be an alternative source instead of freshwater consumption. The consultancy will focus on the installation, commissioning, and initial operation of the GWTS and dripping system, ensuring that the system meets the required performance and sustainability standards.
   

• Rehabilitation of Sanitary Facilities:

  The objective of rehabilitating the dripping network in Harir public park is to efficiently utilize treated wastewater from our treatment system to irrigate park trees, thus promoting sustainable water use and supporting local greenery. This activity will contribute to more resilient infrastructure, improved environmental stewardship, and the sustainable management of water resources.
