Indigenous plants for informal greywater treatment and reuse by some households in Ghana. Journal of Water Reuse and Desalination (2018) 8 (4): 553-565.
Poor greywater management is one of Ghana’s sanitation nightmares due to longstanding neglect. This study looks at local practices of informal phytoremediation, and identifies commonly used plants and benefits. Greywater (kitchen, bathroom and laundry) is mainly disposed of into the open, with few using septic tanks and soakaway systems.
The majority of respondents perceived plants as agents of treatment and most could list 1–2 beneficial functions of the plants. A total of 1,259 plant groups were identified which belonged to 36 different plant species. The top five indigenous plants used are sugarcane, banana/plantain, taro, sweet/wild basil, and dandelion.
The major plant benefits identified were food and medicine. Statistically, no association was identified between the numbers of plants grown and their perceived plant roles, with the exception of an association between plant numbers and benefits. There is demand for improving local practices of using plants in greywater treatment and reuse, since native plants also come with other benefits.
World Water Day is observed on March 22 to raise awareness about the vital importance of water and its cross-cutting impact ranging from public health and youth education to economic development and gender equality. This year’s theme, “Nature for Water,” explores nature-based solutions to water challenges.

According to UN-Water’s World Water Day fact sheet, nature-based solutions can help to manage both water availability and quality. Examples include restoring forests, grasslands, and natural wetlands; reconnecting rivers to floodplains; and creating vegetation buffers along watercourses. These and other nature-based solutions can reduce erosion, improve water quality, enhance biodiversity, recharge groundwater resources, and mitigate flooding downstream.
This issue contains information on upcoming World Water Day 2018 events and studies on nature-based solutions to water supply issues.

Analysis of citizen and decision-maker attitudes to freshwater pollution in Bangladesh cities as a basis for more effective regulation.
This research project is jointly commissioned by the REACH global research programme (led by Oxford University) and the Urban Sanitation Research Initiative, (a 2017-2020 research programme led by Water & Sanitation for the Urban Poor, WSUP). The project will be managed by the Urban Sanitation Research Initiative team with single point-of-contact, but should aim to align with the broad vision and specific requirements of both research programmes.
The research will investigate citizen and decision-maker attitudes to pollution of watercourses in urban environments in Bangladesh, and attitudes towards regulation to reduce such pollution. We require detailed consideration of two specific types of pollution, and of their associated regulation, namely a) faecal contamination arising from widespread discharge from septic tanks, pit latrines, and hanging toilets to surface drains and water bodies and to subsurface water bodies, and b) industrial discharge to surface and subsurface water bodies. However, we would expect detailed consideration of these specific issues to be embedded within a wider framework of analysis of urban freshwater pollution, and its regulation, in Bangladeshi cities.
Bids due: Before 1700 (UK) Tuesday 13th March 2018
Focus country: Bangladesh
Maximum budget: GBP 80,000

The IHUWASH Accelerator India program identifies and supports high-impact WASH business innovations to work with the city governments of Faridabad, Udaipur and Mysuru to solve pressing urban WASH problems. Submissions should focus on one or more of the following urban WASH innovations:
- Safe drinking water
- Last-mile water distribution
- Recovering water supply costs
- Decentralised and improved sanitation solutions
- Improving public/community toilets
- Sustainable faecal waste treatment
- Hygiene behaviour change
Benefits for the selected innovations include opportunities to:
- Roll out small-scale pilots that demonstrate your WASH innovation to governments
- Work directly with key government officials, sector experts and impact investors
- Showcase your innovation through a high visibility nation-wide program
- Raise funds from private sector companies and impact investors
More program details are available here. Applications for the program are now open and they close on 22nd Jan 2018.
Please apply to the program (or) help identify relevant WASH business innovations by nominating them to firstname.lastname@example.org.
IHUWASH is a collaborative initiative between NIUA, Taru, IRC and Ennovent. The three year project is supported by the United States Agency for International Development (USAID) and aims to improve the performance of urban WASH programs for India within a collaborative framework. Under IHUWASH, national and city-level Innovation Hubs are being established to work closely with the Faridabad, Mysuru and Udaipur city governments along with other national level WASH stakeholders.
The IHUWASH Accelerator builds on the experience of the 2016 Sanitation Innovation Accelerator in which Taru, IRC and Ennovent were also involved.

A guide to strengthening the enabling environment for faecal sludge management: experience from Bangladesh, Kenya and Zambia. WSUP, November 2017.
This Guide presents an introduction to conceptualising and strengthening the enabling environment for faecal sludge management (FSM) services in low-income urban areas.
It is based on WSUP’s experience working with Bill & Melinda Gates Foundation to develop market-based solutions for on-site sanitation services in the cities of Dhaka and Chittagong (Bangladesh), Kisumu (Kenya) and Lusaka (Zambia).
Why is FSM so important?
FSM is the process by which faecal sludge is contained, collected, transported, treated and then safely disposed of or reused. 2.7 billion (38%) people around the world are dependent on on-site sanitation facilities like pit latrines and septic tanks, which contain and partially treat faecal sludge on-site (as opposed to centralised systems like sewers that remove waste from households and transport it to treatment facilities).

As part of the IWA Water and Development Congress & Exhibition in Buenos Aires, there will be a special, invitation-only, Leadership Forum on wastewater reuse:
Wastewater Management and Reuse to build Water Wise Cities: Innovative Solutions for Engagement, Planning and Investment, 15 November 2017
Co-organised with World Bank, CAF and IFC
The Forum will take place in three sessions that will lead to the development of a framework to be carried forward and presented at the World Water Forum in Brazil in 2018.
The three sessions are on:
- The wastewater challenge and reuse opportunity
- Unlocking barriers and enabling reuse and recovery – innovative solutions/cases
- A vision and roadmap for wastewater management and reuse to 2030
