Figure 1: Implementation phases and potential activities of a MAR
Project. Section numbers are from the MAR Guidelines.

Standard guidelines are used by project
developers and stakeholders for planning
purposes while engineers, hydrologists
and others use them to standardize their
practices and improve project success. In
2001, American Society of Civil Engineers
- Environmental and Water Resources
Institute (ASCE-EWRI) published the first
Standard Guidelines for Artificial Recharge
of Ground Water as EWRI/ASCE 34-01. As
more MAR projects were developed and
constructed, it became evident that the
original guideline needed to be modernized
and upgraded to provide additional details
on the planning, design, construction and
operation of MAR projects and to improve
the usability of the Guidelines.
In response to that need, an ASCEEWRI MAR Guideline Development
Subcommittee was formed to update
the MAR Standard Guidelines. The
subcommittee consists of individuals from
consulting, state and local government and
academia, who have working knowledge
of and experience in the various phases
of MAR projects1. The MAR Guidelines
have been developed so that project
personnel interested in but perhaps with
limited expertise with MAR will benefit
from understanding how to plan, design,
construct, operate and maintain, and
close MAR facilities. Subcommittee
members developed the MAR Guidelines
with the assumption that users of the
Guidelines would refer to the individual
section or sections needed to address a
given question or concern, rather than

MAR project. Subsection numbers are from the Construction section
of the MAR Guidelines.

reading the document from start to finish.
Therefore, each key phase of implementing
a MAR project is presented in a separate
section (Figure 1).
The MAR Guidelines begin with an
overview of groundwater fundamentals
and of MAR concepts to provide readers
with a common background on these
subjects before going into the details of
implementing a MAR project. MAR topics
that are discussed include sources of
recharge water, pre-treatment, recharge via
surface and subsurface methods, recovery
of recharged water, post-recovery treatment
and end uses.
Following these introductory materials,
the MAR Guidelines devote the bulk of the
material to the phases of a MAR project
(Figure 1). Planning is the essential first
step in developing a successful MAR
project. The Planning section includes
discussion of initial project scoping
activities to identify appropriate locations
and MAR methods. Evaluation criteria
for water sources, site hydrogeology,
environmental considerations and
implementation issues are described,
along with an example scoring matrix to
assist in developing an objective basis for
identifying projects to carry forward for
more detailed analysis and design (Table 1).
The design, construction, operations
and maintenance, and closure phases of
a MAR project are discussed in detail
in subsequent and separate sections,
with subsections devoted to surface and
subsurface methods as appropriate to

provide the reader easier access to the
topics of interest. The Design section
discusses design phases, pilot testing, and
goes into detail on design considerations.
The Construction section discusses site
preparation, the surface or subsurface
recharge and recovery facilities, electrical
and monitoring (SCADA) systems and
water treatment (Figure 2). To remain
effective, MAR projects need ongoing
maintenance and monitoring. The
Operations and Maintenance section
provides details on issues affecting MAR
operations including clogging, shallow
groundwater levels, well redevelopment
and site security. Practical advice is
offered for water quality monitoring
and treatment. Perhaps the most crucial
section of the MAR Guidelines is on data
collection and analysis, because these
elements are ongoing throughout the
process of any MAR project and they form
the foundation of a successful project
(Figures 1 and 2).
One of the most beneficial aspects of
the MAR Guidelines is the emphasis on
practical insights and lessons learned
from past experiences of the authors.
Case studies, from the authors and
our colleagues around the country, are
provided in an appendix to convey both the
details on the range of active MAR projects
and share some of the challenges faced
during implementation of MAR projects.
The MAR Guidelines also include
appendices of a glossary of commonly used
groundwater terms, and a listing of MAR
