1 VOLUME I: DESIGN OF WATER SUPPLY PROJECTS

1.1 Introduction

The existing design manual for water supply [1] and wastewater disposal (3rdedition) was formally adopted by the Ministry that was responsible for Water in 2009 and it consists of three parts namely; volume I on Water supply, volume II on Wastewater disposal and volume III on Water pipelines standards and specifications. Since it is now nearly ten years since the third edition of the design manual was adopted and in the meantime, many scientific and technological changes have taken place including the conclusion of MDGs and adoption of the SDGs in 2015 as well as learning some useful lessons out of implementation of the WSDP I and WSDP II (which is still ongoing); it is felt it is high time to revise the design manu

1.2 Genesis/Background

1.3 Rationale

The existing design manual for water supply and wastewater disposal (3rdedition) was formally adopted by the Ministry that was responsible for Water in 2009 and it consists of three parts namely; volume I on Water supply, volume II on Wastewater disposal and volume III on Water pipelines standards and specifications. Since it is now nearly ten years since the third edition of the design manual was adopted and in the meantime, many scientific and technological changes have taken place including the conclusion of MDGs and adoption of the SDGs in 2015 as well as learning some useful lessons out of implementation of the WSDP I and WSDP II (which is still ongoing); it is felt it is high time to revise the design manual.

1.4 Organisation/description of the manual

The existing design manual for water supply and wastewater disposal (3rdedition) was formally adopted by the Ministry that was responsible for Water in 2009 and it consists of three parts namely; volume I on Water supply, volume II on Wastewater disposal and volume III on Water pipelines standards and specifications. Since it is now nearly ten years since the third edition of the design manual was adopted and in the meantime, many scientific and technological changes have taken place including the conclusion of MDGs and adoption of the SDGs in 2015 as well as learning some useful lessons out of implementation of the WSDP I and WSDP II (which is still ongoing); it is felt it is high time to revise the design manual.

1.5 ESIA and EIA Compliance

The existing design manual for water supply and wastewater disposal (3rdedition) was formally adopted by the Ministry that was responsible for Water in 2009 and it consists of three parts namely; volume I on Water supply, volume II on Wastewater disposal and volume III on Water pipelines standards and specifications. Since it is now nearly ten years since the third edition of the design manual was adopted and in the meantime, many scientific and technological changes have taken place including the conclusion of MDGs and adoption of the SDGs in 2015 as well as learning some useful lessons out of implementation of the WSDP I and WSDP II (which is still ongoing); it is felt it is high time to revise the design manual.

1.6 Water supply
