Technical Issues In Planning Water Reuse Systems<br />

This chapter considers technical issues associated with<br />

planning the beneficial reuse of reclaimed water derived<br />

from domestic wastewater facilities. These technical issues<br />

include the:<br />

• Identification and characterization of potential demands<br />

for reclaimed water<br />

• Identification and characterization of existing sources<br />

of reclaimed water to determine their potential for<br />

reuse<br />

• Treatment requirements for producing a safe and reliable<br />

reclaimed water that is suitable for its intended<br />

applications<br />

• Storage facilities required to balance seasonal fluctuations<br />

in supply with fluctuations in demand<br />

• Supplemental facilities required to operate a water<br />

reuse system, such as conveyance and distribution<br />

networks, operational storage facilities, alternative<br />

supplies, and alternative disposal facilities<br />

• Potential environmental impacts of implementing<br />

water reclamation<br />

Technical issues of concern in specific reuse applications<br />

are discussed in Chapter 2, “Types of Reuse Applications.”<br />

3.1 Planning Approach<br />

One goal of the Guidelines for Water Reuse is to outline<br />

a systematic approach to planning for reuse so that planners<br />

can make sound preliminary judgments about the<br />

local feasibility of reuse, taking into account the full range<br />

of key issues that must be addressed in implementing<br />

reclamation programs.<br />

Figure 3-1 illustrates a 3-phase approach to reuse planning.<br />

This approach groups reuse planning activities into<br />

successive stages that include preliminary investigations,<br />

screening of potential markets, and detailed evaluation<br />

of selected markets. Each stage of activity builds<br />

on previous stages until enough information is available<br />

to develop a conceptual reuse plan and to begin negotiating<br />

the details of reuse with selected users. At each<br />

stage, from early planning through implementation, public<br />

involvement efforts play an important role. Public involvement<br />

efforts provide guidance to the planning process<br />

and outline steps that must be taken to support<br />

project implementation.<br />

• Identification of knowledge, skills, and abilities necessary<br />

to operate and maintain the proposed system<br />
