Nature-Based Solutions to reduce pollution of lake Hawassa

The use of wetlands for water pollution control dates back to the ancient Chinese and Egyptian civilizations. Wetlands reduce water pollution by removing pollutants coming from surface waters. Constructed wetlands (CW) provide sustainable, low cost, robust and efficiently engineered systems for water treatment, with added ecosystem services.

Since its construction in 2013, Amora Gedel (Eagle’s Valley) CW has been serving to improve the quality of storm water discharging into the lake Hawassa. Amora Gedel was constructed as a joint project by the Hawassa City Administration and the World Bank in Hawassa City. Due to increasing wear-and-tear, human activities, inadequate operation and maintenance over the years, a general overhaul was much needed. Protecting lake Hawassa (PLH) members identified the CW as one of the priority action areas.

Joint action

Earlier this year, NatuReS and the Hawassa Municipality embarked on rehabilitating the Amora Gedel CW. The rehabilitation is part of the PLH Partnership activities. Pooling resources together, NatuReS took the responsibility over the renovation works. Ensuring the long-term sustainability and functionality of the CW will be a task overseen by the municipality.

An Ethiopia-based wastewater construction company is conducting the rehabilitation and supervised by Aquacon Engineering consultants. The Municipality also provided operators for maintaining the CW once rehabilitated. A team from the Municipality, Acquacon, NatuReS and community representatives will carry out the inspection and follow-up work.

The Rift Valley Lakes including Lake Hawassa are currently experiencing a rise in water levels. Amora Gedel rehabilitation is facing challenges from this water level rise, as it results in a mix of lake and storm water. Considering this phenomenon, NatuReS and its partners are acting to reduce the risk and make the CW climate-proof. Raising the whole water treatment ponds by 50cm and rerouting the inlet deliver channel is the action taken to address this risk.

Nature-based solution

Restored to its former glory, the Amora Gedel CW will again be able to treat the first flash of storm water from the city’s drainage channels. This is important, as the first flow is the most polluted, sweeping away dust and garbage from the drainage channels towards the lake. The municipal staff will be collecting large particles such as plastic bottles trapped by the trash rack. Through a biological process, the smaller pollutants, including heavy metals, will be filtered from the water in the CW. This process will make use of aquatic plants (i.e. reeds, duckweed), naturally occurring microorganisms and a filter bed (sand, soils and gravel). The completion of the CW will be right before the start of the rainy season in June.

Objectives of the programme

In Uganda, NatuReS focuses on strengthening the inclusive green economy in the Greater Kampala Metropolitan Area as well as Gulu City. Objectives of the programme are:

  • enabling multi-stakeholder partnerships in solid waste management & circular initiatives, urban flood resilience, wetland management and sustainable eco-industrial parks
  • increasing capacity of public and civil society actors, as well as the private sector, on natural resources stewardship
  • embedding lessons learnt and emerging good policy regarding natural resources stewardship

Multi-stakeholder partnership

The Greater Kampala PET plastic recycling partnership is a multi-stakeholder partnership. Accordingly, partners from private, public sector and civil society are:

  • Uganda Ministry of Water and Environment,
  • National Environment Management Authority (NEMA),
  • Kampala Capital City Authority (KCCA),
  • Coca-Cola Beverages Africa,
  • Mukwano Industries Uganda Ltd.,
  • Uganda Water & Juice Manufacturers Association,
  • Global Green Growth Institute.

Together, they strive towards improving the sustainable management of PET plastic waste in and around Kampala by developing an inclusive green recycling sector.

A ceremonial handover of 10 tuktuks from the Ministry of Water and Environment to KCCA followed. The vehicles will facilitate waste collection in ten municipalities within the Greater Kampala Metropolitan Area. Above all, they will enable efficient and timely collection of waste, hence making sure it can be channelled into the recycling value chain.

Improving water supply for low income communities in Lusaka

As one of the fastest-growing cities in Southern Africa, the Zambian capital Lusaka faces numerous threats to its water security. This is especially the case for low-income areas, where mere access to water remains a challenge. One such area is George Compound, a peri-urban community of 200,000 residents located in the Western part of Lusaka. Many residents fetch their water at public kiosks, serviced by the local utility company’s wellfields. However, some residents still fetch it from contaminated or heavily polluted shallow wells.

To address this problem, the Lusaka Water Supply and Sanitation Company (LWSC) implemented a water supply improvement project in George compound and the surrounding industrial area. The project was financed by Zambian Breweries (ZB) at a cost of 150,000$. It involved the drilling of a borehole and the installation of a 3.4km pipeline to George compound.

Over 40,000 community members will benefit from this collective action, implemented under the Lusaka Water Security Initiative (LuWSI) partnership. Additionally, it will also serve as a COVID-19 prevention measure, as it provides reliable access to water and hence makes e.g. regular hand-washing possible.

The Minister of Water Development, Sanitation and Environmental Protection, Honorable Rapheal Nakachinda, commissioned the project infrastructure on March 19th, 2021. NatuReS Zambia as partners of LuWSI facilitate and promote such collective action in order to manage natural resources for sustainable growth and better livelihoods.

Environmental threats affecting both business operations and the public

Discussions focused on water and environment security in private sector operations. Frequent flash floods threaten e.g. industrial areas, namely Namanve, Ntinda and Bugolobi. They pose both an environmental threat and have a detrimental effect on business operations, as machinery can be damaged or access roads get blocked. For instance, recently employees at Namanve Industrial Park were blocked in their workstations due to floods having swallowed up the outgoing streets. Consequently, factories like Hima Cement Ltd. have embarked on improving drainage systems at their own costs within their boundaries. 

Participants also discussed water pollution, another environmental threat affecting the private sector. For example, Jesa Farm Dairies, Uganda’s leading dairy processing company, extracts water for their operations from the River Mayanja. However, it is increasingly polluted. Therefore, Jesa increased its investments in water treatment to ensure availability of clean water for their operations.

Cooperation is key

The public sector is open to partner  with the private sector in reducing water and environmental risks. During the event, participants long discussed ideas to leverage actions. Among others, they agreed to establish a roadmap for continuous engagement between stakeholders who are affected by and affect water resources and the environment. 

In the end, participants agreed on a follow-up meeting at the Ministry to concretize their ideas. Also, similar meetings between private and public sector are now set to occur annually during Uganda Water & Environment Week.
