This publication provides information and guidance on pumping methods used to control groundwater as part of the temporary works for construction projects. Subjects covered include potential effect of groundwater on construction works, groundwater control techniques, safety, management and contractual matters, legal and environmental issues that arise when groundwater is pumped and discharged, site investigation requirements, and design methods for groundwater control schemes.

Careful management is required for deep lead pumping bores . Such bores must be located to minimize migration of poor quality groundwater from either bedrock or overlying aquitards . The extraction rate for a region also must be ...
Here is what is discussed: 1. PLANNING, 2. FIELD PUMPING TEST, 3. DESIGN, 4. INSTALLATION AND OPERATION, 5. CONTRACT SPECIFICATIONS.
Praise for the Second Edition: "This is the book that the dewatering sector really needs – it is reliably based on sound theory and profound understanding of the physical processes, yet is presented in a very accessible and user-friendly ...
Faced with growing costs associated with deeper wells and the need for ever more advanced technology for extracting water, these towns find they lack the resources to maintain current agricultural practices. ø In this timely assessment of ...
The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM).

However, local control enjoys strong citizen support and is firmly established in Texas, Nebraska, and Kansas. Texas represents the extreme, with all powers to regulate groundwater being vested in districts formed at the discretion of ...
This publication will introduce you to methods of dewatering and groundwater control for excavations for buildings and other structures and earth construction.
Consequently, many engineering ventures now require a more in-depth assessment of potential environmental impacts of dewatering and groundwater control, and this book details the latest best practices to evaluate and address them.
