Sanitation Technology Options

In this document, you will find more information on the various technical options that meet the requirements for basic sanitation. These need to be considered within all the sustainability requirements, e.g. affordability, operation and maintenance. The options are divided into two categories: Dry non-water reliant on-site systems and wet systems (that do require water for operation).

Urine diversion components. Overview of Urine Diversion Components such as Waterless Urinals, Urine Diversion Toilets, Urine Storage and Reuse Systems

The publication explains the purposes of urine diversion, its benefits and challenges, possibilities of urine treatment and reuse in agriculture. It provides an overview on design and operational aspects for equipment needed, such as waterless urinals and urine diversion toilets. An appendix with a worldwide listing of suppliers for waterless urinals and urine diversion toilet pedestals and squatting pans is also available.

Low-Cost Sustainable Sanitation Solutions for Mindanao and the Philippines. A Practical Construction Field Guide

After a brief introductory chapter on the Philippine sanitation situation and basic principles of sustainable sanitation, the manual focuses on the introduction of different low-cost sanitation solutions comprising the arborloo toilet, the 1-chamber and 2-chamber UDDT, hanging UDDTs, and the ecopee urinal. Each technology is briefly described by giving general information on how it works, operation and maintenance requirements, reuse or safe disposal options, and in which setting this technology might be appropriate. In addition, a picture-based guide on how to construct each technology is provided as well as the necessary technical drawings and rough cost estimates based on current prices. Since a sanitation system does not end with the toilet itself, the last chapter also provides information on the overall management of the system including collection, transport, treatment, and final reuse of urine, feces and composting products in agriculture.

Design Specification & Requirements Manual. Updated 2010

Among other things, there is much information about the sewer collection system in the City of London, (Ontario-Canada). There will be site-specific situations where the design will depart from these practices as it is not possible nor is it the intention of the City to anticipate every situation.

Guide to Septage Treatment and Disposal

The purpose of this guide is to present practical information on the handling, treatment, and disposal of septage in a concise, recommendations-oriented format for easy use by administrators of waste management programs, septage haulers, and managers or operators of septage handling facilities. The guide is not intended to provide detailed engineering design information.

The Impact of Densification by Means of Informal Shacks in the Backyards of Low-Cost Houses on the Environment and Service Delivery in Cape Town, South Africa

This paper investigates the state-sponsored low cost housing provided to previously disadvantaged communities in the City of Cape Town, South Africa. The design of state-subsidised houses and the construction of unplanned housing in the backyard added enormous pressure on the existing municipal infrastructure and the environment. Municipal water, sewerage systems and solid waste disposal cannot cope with the increased population density combined with the poor sanitation behaviour of the inhabitants of these settlements. The low-cost housing program in South Africa requires improved management and prudent policies to cope with the densification of state-funded low-cost housing settlements.
