Depending on the initial situations and respective local circumstances, there is no guarantee that single measures described in the toolbox will make the local water and sanitation system more sustainable. The main aim of the SSWM Toolbox is to be a reference tool to provide ideas for improving the local water and sanitation situation in a sustainable manner. Results depend largely on the respective situation and the implementation and combination of the measures described. An in-depth analysis of respective advantages and disadvantages and the suitability of the measure is necessary in every single case.

4 Fertigation Find this presentation and more on: 4 What is fertigation? Fertigation means irrigation plus fertilization which can be done through buried or surface drip-lines or through sprinklers. Recent technological developments in the drip and micro-irrigation methods have accelerated the adoption of fertigation for a wider range of crops, including fruit trees. To reduce dependence on freshwater and maintain a constant source of irrigation water throughout the year, waste waters of varying qualities can be used in agriculture. Generally, only waters that have had secondary treatment (i.e. physical and biological treatment) should be used to limit the risk of crop contamination and the health risk to workers. 1. Concept

6 Fertigation Find this presentation and more on: How it can optimize SSWM Implementation and use of Fertigation can help in optimizing your local water management and sanitation system and make it more sustainable by: Minimizing competition between agriculture and urban areas for high quality freshwater supplies, particularly in arid, semi-arid and densely populated regions, will increase the pressure on this resource. Providing readily available nutrients found in greywater/wastewater to the plants Providing a relatively safe way of discharging pre-treated wastewater into the environment

7 Fertigation Find this presentation and more on: 7 Fertigation with the use of irrigating/microirrigating technologies must be regularly check since they are susceptible to clogging. The management of risk is facilitated by conducting an analysis of the entire production cycle from waste generation to consumption of the product. Knowledge of the system is then used to identify health protection measures that can reduce health risks at different points, in order to arrive at the agreed health-based targets. Public health policies for interventions should ensure that the most cost-effective measures are applied in specific contexts. Guidelines for the use of excreta and greywater in agriculture exist from the WHO (2006) 3. Operation and Maintenance

8 Fertigation Find this presentation and more on: Applicability Fertigation does not provide adequate treatment for raw wastewater and this technology should only be considered for discharging pre-settled wastewater or greywater as well as rainwater. Fertigation is suitable for both rural and peri-urban areas Fertigation is very much suited in areas where fresh water is very scarce, like urban areas, particularly in arid, semi-arid and densely populated regions, will increase the pressure on this resource.

9 Fertigation Find this presentation and more on: Advantages and Disadvantages Advantages: Minimizing soil compaction by avoiding heavy equipment traffic through the field to apply fertilizers Reduced energy demand Reduced labor input careful regulation and monitoring of nutrient supply Even distribution of nutrients throughout the root zone application of nutrients matched in amounts and timing to the plant nutrient requirements (BURT et al. 1998) Disadvantages: Fertigation using dripi-irrigation or micro-irrigation is very sensitive to clogging May require expert design and installation Not all parts and materials may be available locally
