Construction of wire-reinforced cement mortar tanks
Neil Herath, Comminity Water Supply & Sanitation Project (CWSSP), Ministry of Housing, Construction & Public Utilities, Sri Lanka (1995)
this document has been scanned from earlier manuals and standardizations prepared by Neil Herath for CWSSP – Sri Lanka ( April 1995), and as Manual 3 of the Technical Manual Series on Rural Water Supply and Sanitation, Gravity Water Supply Systems: design and construction (January 2005). It is redesigned to look like the 2005 CWSSP manual guiding field work on wirereinforced cement mortar tanks, commonly known as ferrocement tanks (Han Heijnen, October 2010) (

Organizations with experience in the construction of rainwater harvesting systems
SamSamWater Foundation
SamSamWater Foundation aims to increase the number of people in developing countries with sustainable and reliable access to water and sanitation.
'SamSam' means 'together'. We work together to reach our goal: safe and reliable water to all! We believe in practical solutions, realised in close collaboration with our partners and beneficiary communities.
RAIN Foundation
RAIN is an international network with the aim to increase access to water for vulnerable sections of society in developing countries - women and children in particular - by collecting and storing rainwater.
Started in December 2003, RAIN focuses on field implementation of small-scale rainwater harvesting projects, capacity building of local organisations and knowledge exchange on rainwater harvesting on a global scale.
Acacia Water
Acacia Water “for solutions in groundwater” was established in 2003 at the Vrije Universiteit Amsterdam (Faculty of Earth and Life Sciences). Acacia Water focuses on groundwater in relation to surface water, environment and infrastructure. This varies from implementation of field measurements and model calculations, to giving training and strategic advice. Acacia distinguishes itself by the cooperation with the University, as a result of which Acacia Water has access to the latest scientific developments in the field of hydrology and environment. We translate this knowledge to innovative and practical solutions.
