يمكن استخدام مياه الصرف متفاوتة الجودة في الزراعة؛ للحد من الاعتماد على المياه العذبة، ولضمان مصدر دائم للمياه لأغراض الري على مدار السنة. ومع ذلك، ينبغي أن تُستخدم المياه التي خضعت للمُعالجة الثانوية فقط (أي المُعالجة الفيزيائية والمُعالجة الحيوية) للحد من مخاطر تلوث المحاصيل والمخاطر الصحية على العاملين.
هناك نوعان من تقنيات الري المناسبة لمياه الصرف الصحي المُعالجة:
1) الري بالتنقيط فوق أو تحت سطح الأرض؛ حيث يتم تنقيط الماء ببطء على الجذور أو بالقرب من منطقة الجذور.
2) الري السطحي؛ حيث يتم غمر الأرض بالمياه في سلسلة من قنوات الري أو الأخاديد.
ولتقليل التبخر ونشر مسببات الأمراض في الهواء ينبغي تجنب الري بالرش.
إن استخدام مياه الصرف المُعالجة بشكل صحيح يُمكن أن يقلل -إلى حد كبير- من الاعتماد على المياه العذبة، و/أو تحسين إنتاجية المحاصيل الزراعية من خلال توفير المياه والمُغذيات اللازمة للنباتات. ولا ينبغي أن تُستخدم مياه الصرف أو المياه السوداء غير المُعالجة في الري، كما أن المياه المُعالجة بشكل جيد يجب أن تُستخدم بحذر. والاستخدام طويل المدى للمياه المُعالجة بشكل غير صحيح أو المياه رديئة المُعالجة قد يُسبب ضررًا طويل المدى على تكوين وبِنية التربة وقدرتها على الاحتفاظ بالماء.

There are two kinds of irrigation technologies appropriate for treated wastewater:
- Drip irrigation above or below ground, where the water is slowly dripped on or near the root area; and
- Surface water irrigation where water is routed overland in a series of dug channels or furrows.
To minimize evaporation and contact with pathogens, spray irrigation should be avoided.
Properly treated wastewater can significantly reduce dependence on fresh water, and/or improve crop yields by supplying increased water and nutrients to plants. Raw sewage or untreated blackwater should not be used, and even well-treated water should be used with caution. Long-term use of poorly or improperly treated water may cause long-term damage to the soil structure and its ability to hold water.
يجب أن يكون معدل استخدام مياه الصرف الصحي المُعالجة للري مناسبًا للتربة والمحاصيل والمناخ، وإلا يصبح الاستخدام مضرًّا. ولزيادة قيمة العناصر المغذية في مياه الري؛ فإنه من الممكن أن يُخلط )يُحقن( البول مع مياه الري، وهذا ما يسمى “التسميد في الري )أو الري المُسَمَّد( Fertigation” )أي التسميد + الري.( و يجب أن تتناسب نسبة تخفيف البول في المياه مع الاحتياجات الخاصة للمحصول ومقاومته.
ويجب مراعاة وجود ضغط تشغيل مناسب في أنظمة الري بالتنقيط ومراعاة الصيانة الدورية؛ للحد من احتمالية انسداد نظام الري )خصوصًا مع البول الذي سوف يترسب منه الستروفايت Struvite تلقائيًّا).
يجب أن تَسبِق المُعالجة المناسبة )أي الحد من العوامل المسببة للأمراض بشكل كافٍ( منظومة الري للحد من المخاطر الصحية للأشخاص الذين يعملون باتصال مباشر مع المياه. علاوة على ذلك، فإن المياه قد لا تزال ملوثة بمواد كيميائية مختلفة قد تم صرفها في نظام المُعالجة، وذلك اعتمادًا على درجة المُعالجة التي خضعت لها التدفقات السائلة الخارجة. وعند استخدام التدفقات السائلة المُعالجة للري، ينبغي على المنازل والمصانع المتصلة بالنظام أن تكون على دراية بالمخلّفات المناسبة وغير المناسبة التي يمكن صرفها بالنظام. والري بالتنقيط هو نوع الري الوحيد الذي يجب أن يُستخدم مع المحاصيل الصالحة للأكل، ومع ذلك يجب توخي الحذر لمنع العمال والمحاصيل المحصودة من ملامسة التدفقات السائلة المُعالجة. وينبغي الاستعانة بإرشادت منظمة الصحة العالمية WHO لاستخدام مياه الصرف؛ وذلك من أجل الحصول على معلومات مُفصَّلة وتوجيهات محددة.
يجب أن يتم عمل غسيل دوري لأنظمة الري بالتنقيط؛ لتجنب نمو الغشاء الحيوي Biofilm، ولتجنب انسدادها بسبب جميع أنواع المواد الصلبة. ويجب الكشف عن التسريبات في الأنابيب؛ لأنها عُرضة للتلف من قِبل القوارض أو البشر. والري بالتنقيط أكثر تكلفة من الري التقليدي، ولكن يُحسِّن الإنتاج ويُقلل تكاليف المياه والتشغيل. كما يجب على العاملين ارتداء الملابس الواقية المناسبة.

Struvite Production from Source Separated Urine in Nepal
This thesis explores the potential reuse of struvite effluent in Siddhipur Nepal. The hypotheses being investigated are that preliminary struvite precipitation prevents clogging during drip fertigation with urine and that drip-fertigation with urine is superior to bucket spreading, because the ammonia volatilization is strongly reduced.

Simple low-cost drip irrigation is practical and affordable for smallholder farmers. It has been successfully used in India and is becoming more popular in other southeast Asia and sub-Saharan Africa. It can reduce both water and labor use by as much as 20-50%. Yield of vegetables also can be increased by at least 10%. Our farm trials in Cambodia showed yield increases of 20-50% compared to traditional hand watering. Low pressure irrigation is also a key component of the African Market Garden concept jointly developed in west Africa with ICRISAT. This 10-chapter drip irrigation manual provides basic, step-by-step procedures for installing simple drip irrigation systems for different crops, climates, and soils.

Reduced water and energy demand as well as the substitution of fertilizer by urine and faeces-derived manure were expected advantages.

Different examples show how water can be reused and recycled and thus increasing water efficiency in urban, peri-urban and rural areas.

Wastewater reuse conserves fresh water and nutrients, is inexpensive, and reduces pollution of water systems.

Smallholder farmers in the semi-arid regions of eastern and southern Africa have to depend on erratic, unreliable and low rainfall for their livelihoods. Subsistence staple food crops are generally grown under rainfed conditions. Consequently there is a growing interest in complementing this risky rainfed food production with cultivation of high-value vegetable crops and fruits. But in most cases this means these small-scale vegetable gardens and orchards must be irrigated in order to assure an economic return. Drip irrigation methods minimize the non-productive water losses associated with conventional irrigation, e.g. from evaporation and soil runoff, and thus can make more efficient use of the already minimal water supplies in these arid areas. But until recently drip irrigation technology had been associated with costly investments available only to large commercial farmers. Now there is growing interest in the technique and many efforts are being made around the world to develop low-cost, simple, drip irrigation systems suitable for smallholder farmers. This handbook presents some of these drip irrigation options that can be promoted by extension officers in eastern and southern Africa. It describes the most interesting small-scale low-cost drip irrigation methods of which the author and the other contributors have practical experience. It also gives a brief overview of methods that have been used successfully in other parts of the world with details of how to obtain further information about them or order equipment.
