“…In consensus, consistent with site observations and findings by Rahman et al (2013) and Chew et al (2014), all stakeholders agreed that most common causes of leaking for toilets and wet areas in concrete frame building, regardless of PC or IRC constructions are leaking through cracks, leaking through pipe penetration, leaking through cold joints and Poor waterproofing workmanship.…”

“…According to Rahman et al (2013) in Malaysian context, IRC is still the preferred method of construction for toilets and wet areas in PC structure with two (2) most common approaches namely; a) The whole toilet supporting structural elements full IRC construction or b) Hybrid method where the columns and lower half of beams remain as PC while only the top of beam and slab adopt IRC. The use of IRC method of construction for toilets in a PC frame building often slow down the progress of work, increase material wastages, produce a lower quality of work and increase man-power.…”

“…Based on research by Rahman et al (2013), under an ideal circumstance of IBS application, the whole toilets should be constructed as a complete Prefabricated Toilet Units (PTU). In developed countries like Singapore and Japan, PTU is commonly used in aircraft industry, ships construction and in building construction.…”

Hybrid construction method with In-situ reinforced concrete (IRC) for wet areas in predominantly precast concrete (PC) buildings to overcome leakage problem is a setback for full IBS adoption. Various options explored to reduce IRC at toilet only to discover the answer is possible within the existing parameters of IBS. The proposal adopts composite construction comprised of metal permanent formwork and ISC casting for toilet floor while PC components remained as buildings structural framing system. This proposal combined different elements of IBS systems offers all the advantages associated with IBS; minimize wastages, better quality, shorter construction period and minimized unskilled workers.

For fecal sludge from households in low- and middle-income countries to be treated offsite it needs to be removed, which can be greatly affected by the pit latrine floor design. However, it is unclear whether precast pit latrine concrete floors (latrine slabs) can withstand emptiers and their equipment. To investigate this issue, 28 prefabricated latrine slabs were purchased in two cities of Malawi. They were first visually evaluated, and then their compression strength was tested. Additionally, each seller was asked a series of questions to better understand their business, training, and construction practices. Results showed that households should perform due diligence to ensure that they are purchasing a safe precast latrine slab. Commonly reported problems included nonstandard reinforcement material and spacing, in addition to slabs that were not thick enough or were not large enough in diameter. The results of this research illustrate the inherent complexity in ensuring high-quality decentralized sanitation solutions and how one component, the user interface, if implemented poorly, can affect the rest of the value chain. The findings from this work can help inform training and initiatives that engage artisans and suppliers who play a role in the provision of onsite sanitation service delivery.

“…These products range from those pre-cast by local masons who use concrete to construct toilet products for user-interfaces such as concrete slabs for latrines/ toilets, pedestals, pans or urinals and biogas receptacles as well as containment systems (septic tanks). More sophisticated prefab toilet components are produced on factory floors and assembled at construction sites (Rahman et al, 2013). The fully assembled prefab toilets are designed, coordinated and tested in advance under controlled factory production environments.…”

The value chain (VC) system is a key way to address important sanitation technological and institutional gaps in production and service delivery and could constitute a natural platform for development actions and also serve as a market systems approach to improve access to safely-managed sanitation. It has been suggested that sanitation could boost local and national economies and global interconnections with a growing recognition that the private sector can play a bigger role in delivering the Sustainable Development Goal for sanitation, and help businesses understand value-added and product opportunities. This book proposes a pathway towards re-thinking the sanitation value chain (SVC) and suggests that it should cover all processes, activities and products of enterprises/actors in the sanitation supply chain that provide value-added services within each stage. Following the Regenerative Sanitation Principles, this book presents a new perspective to the SVC known as the ‘integrated functional sanitation value chain’ (IFSVC) to address operational functions within sanitation systems in combination with sanitation enterprises, operators and external actors that support the growth of the sanitation economy. The underlying premise of this book is that the IFSVC represents a new perspective that would have major social, environmental and economic implications for local, national, regional and global sanitation service delivery. It is hoped that researchers, business leaders, entrepreneurs, government officials and funders will find this book valuable, and be inspired and enabled to carry sanitation work forward in their own spheres of operation. The book gives several examples of encouraging developments, particularly in technical and business model innovation. It is our hope that this book will provide the stimulus for new learning and its application, particularly through cross-disciplinary and cross-sector partnerships that bring together all the skills and capabilities needed to deliver a fully effective IFSVC.
