Many people in developing countries rely upon untreated groundwater supplies for their drinking water (e.g. from drilled boreholes, tube wells, dug wells or springs). The introduction of on-site sanitation systems might lead to groundwater contamination. The purpose of this manual is to provide guidance on how to assess and reduce the risk of contamination of groundwater supplies from on-site sanitation systems and is aimed at those responsible for planning low cost water supply and sanitation schemes.

This presentation introduces the new and innovative concept of the addition of charcoal; lacto-fermentation and subsequent vermicomposting to treat the products of urine diversion dry toilets. The new process is inspired by the practices of the pre-Colombian culture in the Amazonian region that produced highly fertile anthropogenic soil (terra preta).

This paper gives a short overview on the historical background and the formation of terra preta in the Amazon region. The composition of terra preta and the importance of charcoal and other ingredients for the formation and their carbon sequestration capacity are discussed. There is an outlook on how to recreate this very useful and nutrient rich type of earth in a synthetic way by mentioning current sources and studies.

The paper provides information on the discoveries of terra preta at various regions within the Amazonas area. The different soils are explained and historical background is given. Besides characteristics of the different soil types a classification is done. Results of different studies concerning the application of the pre-Columbian Indigenous techniques for sustainable land use and field and laboratory research are provided.

The publication explains the purposes of urine diversion, its benefits and challenges, urine precipitation, urine treatment and reuse in agriculture. Further, it provides an overview on design and operational aspects for equipment needed, such as waterless urinals and urine diversion toilets including supplier information and indicative costs. Overall, it pulls together scattered knowledge around the topic of urine diversion in a concise manner.

The objective of this study was to investigate the suitability of terra preta sanitation (TPS) systems as an alternative sanitation option. The effects of lactic-aid conditions in urine-separation dry toilets and a subsequent treatment by vermicomposting are assessed. Research focused on analysing standard chemical and biochemical properties of the toilet products to evaluate their stability and maturity, and establish nutrient status.

With the move to a risk based approach to dam safety there has been a concomitant focus on estimating the probability of failure of dams. The majority of risk guidelines relate to the total probability of failure and therefore the individual probabilities estimated for different components and loading conditions need to be combined.

One of the most exciting new trends in water quality management today is the movement by many cities, counties, states, and private-sector developers toward the increased use of Low Impact Development (LID) to help protect and restore water quality. LID comprises a set of approaches and practices that are designed to reduce runoff of water and pollutants from the site at which they are generated. By means of infiltration, evapotranspiration, and reuse of rainwater, LID techniques manage water and water pollutants at the source and thereby prevent or reduce the impact of development on rivers, streams, lakes, coastal waters, and ground water.
