Often, the high cost of wastewater treatment and management is a major impediment towards implementing such projects. Governments in developing countries have more pressing needs than wastewater management such as dealing with war and conflicts, health care and food supply. Wastewater management is frequently low on the list of priorities. Many developing countries suffer from political interference in environmental decisions such as site selection and other aspects related to construction and operation. Even the most advanced technology should be supported by the appropriate institutions and enforced legislation to ensure maximum efficiency. The financial support of international organizations and developed countries is essential, yet it is imperative that local conditions are considered to make full use of any aid. Otherwise, there is no point of funding such projects. The adoption of inappropriate technology and failure to take into consideration the local conditions of the targeted community result in project failure that is often blamed on the lack of technical know-how and financial resources. Sometimes millions are spent on construction and a few dollars on gathering reliable design data. Replication of successful projects is beneficial but the system should be adjusted to the local conditions, especially climatic conditions. More often than not, the low-cost technology is chosen without any other consideration. Rural areas in developing countries cannot meet current and future sanitation requirements with just one funded project. A comprehensive and long-term strategy that requires extensive planning and implementation phases is vital for sustainable wastewater management.
