Municipalities under-serviced by state agencies or water companies: Many municipalities are badly served by state sewage agencies, and privatized companies. Yet affordable alternatives are available. Wastewater recycling is suitable for municipalities and city suburbs with 1,000 - 50,000 population. These have enough land to recycle wastewater.
State agencies having trouble to meet standards:
Many facilities constructed years ago by state agencies are overloaded. Operators face fines from state environmental agencies. Wastewater recycling brings stabilization ponds up to legislative requirements, and produces products for operators. This saves financial penalties and makes productive use of treatment sites.
Fertilizer and feed are the largest costs for farmers. Wastewater recycling reduces these costs. Farms are able to channel manure into biogas digesters, fish ponds and macrophyte ponds to produce feed and other products. This generates revenues and provides inexpensive feed.
Landless farmers who acquire poor quality land:
Landless families are acquiring bad quality farmland via legal expropriation or invasion. Wastewater recycling helps restore depleted soil and reduce the amount of land required for farmers to make a living. Agencies which grant land to farmers have the chance to help them increase land-use efficiency with wastewater recycling.
Agro-industries produce high-nutrient waste, useful for wastewater recycling. Examples are rice processing, meat processing, breweries, dairy production (ice-cream, milk, yogurt), fruit processing, pig farming, aquaculture (fish and crustaceans), and poultry.
Combined municipal & agro-industry facilities:
This system combines agro-industry waste with municipal wastewater. For example, agro-industries or farms located on the outskirts of municipalities or close to municipal wastewater treatment facilities have the possibility to co-operate with municipalities on combined wastewater treatment, reducing costs and generating revenues.
Restaurants and hotels:
Many tourism facilities are able to process liquid and food wastes and with small recycling facilities which generate biogas, fertilizer and garden vegetables.
Complexes with landscaping:
Many office complexes, schools and universities have extensively landscaped grounds. These are convertible into attractive recycling facilities which provide treated water. In some cases the facilities could be used to provide vegetables for restaurants in these complexes.
Pollution control agencies:
Costs for conventional sewage treatment strain agency budgets. Industries and municipalities have trouble conforming to regulations due to costs. Wastewater recycling provides cost-saving incentives to obey regulations.
Water-borne intestinal diseases are among the most common diseases in tropical countries. Most are carried in drinking water contaminated by sewage. This system is a cost-effective method for reducing pathogens.
Multilateral development agencies:
Wastewater recycling provides one avenue for agencies to meet their own new environmental guidelines for municipal sewage treatment and agro-industry development.
Environmental liability is becoming a severe source of losses for insurance companies. Liability for water pollution is a growing concern. This system allows insurance companies to reduce the liability of their clients.
This system helps prevent deforestation, promote biodiversity, and reduce water pollution while supporting sustainable development needs.
