Tools And Techniques

A companion paper dealt with the tasks required to investigate and assess the components of non-revenue water (NRW). This is a necessary first step in a diagnostic approach to understanding the condition of the network, the way that it is operated, and the constraints acting upon it. This second part deals with the tasks and tools required to address the constraints, and to develop a strategy to reduce NRW which is practicable and achievable, and which can be adapted for any distribution network anywhere in the world. Not all utilities, particularly those in developing countries, have the luxury of a well-developed and efficiently managed network. The paper deals with the tasks required to upgrade the network, and to review and improve the operational policies and practices, before the tools and techniques to reduce NRW can be put in place. The paper discusses each step of the strategy and its development, from upgrading the network by improved infrastructure management and zoning, to the available techniques and equipment for monitoring and detecting real and apparent losses.

Poor sanitation is a major problem for health and water resources in many developing countries. Inexpensive but also attractive toilets could be a way to fight these problems. However, radical new ideas are needed to identify innovative solutions. Such novel ideas might be found by using systematic design methods that search nature for animals and plants that solve similar problems. The paper describes how four conceptual sanitation solutions for dry toilets solving problems with smell, cleaning and flies can be made in collaboration between a design engineer and a biologist using biomimetic design methods. The solutions have the potential to offer significant improvements compared to conventional non-water-based sanitation.

This paper describes origin and development of sewer system in Gdansk, Poland, designparameters for water use and wastewater generation, gravity siphons, pumping stations,sewage fields. It was the first and complete solution of urban water on the Europeancontinent. This report gives literature review, background of decisions, comprehensive resultsand final conclusions. Paper focused on the water-based infrastructure in the city, namelypotable water, sewerage, irrigation and drainage. Described technologies are still in use andcan be used in the future in developing countries, for example for re-use of wastewater onirrigation fields.
