Sec 4.1
Regulatory Requirements
The purveyor shall satisfy the requirements of federal，state or provincial,local, or other appropriate regulations as applicable. Purveyors shall demonstratethat they meet the applicable regulations for their own jurisdiction.
Sec 4.2 Management Programs
4.2.1 Program performance goals. The purveyor shall establish goals forreclaimed water quality，plant efficiency,and distribution system performance,independent of those specified by the applicable regulations. The purveyor shallconduct monitoring to determine conformance with the goals, and take appropriateaction if goals are not achieved.
4.2.2 Establishing a viable customer base. Purveyors should conductappropriate studies and/or investigations to determine the anticipated customerbase before designing the reclaimed water system.
4.2.3 Marketing to ne ctustomers. The purveyor shall develop a plan tomarket reclaimed water to new customers to inform them of the value of reclaimedwater and the availability to connect to the reclaimed water system. The planshould include market studies and surveys to identify areas to serve with reclaimedwater.
4.2.4 Public information and education program. The purveyor shalldevelop or incorporate into existing programs outreach efforts aimed at raisingawareness of reclaimed water. Key components of this program should includeopenness; effectively communicating the value of reclaimed water;reuse waterquality;suitability of the water for identified uses; quantity; information on opportunities for reuse，including examples of uses that are allowed and notallowed; and delivering early and consistent messages.
4.2.5 Integrated resource plan. The purveyor shall include reclaimed waterwhen considering water supply options and, where appropriate, include reclaimedwater as part of the supply portfolio when conducting supply and demandforecasting.
4.2.6Water demand. The purveyor shall have a program to evaluatereclaimed water demand based on available customer use records, irrigated acreage,or manufacturer’s literature for cooling-tower equipment. The evaluation ofdemands will consider quantity, quality, seasonal demands, seasonal storage needs,and delivery pressures appropriate to each customer.
4.2.6.1 Mitigating shortages. The purveyor and water supplier shalldevelop and maintain a plan for mitigating reclaimed water shortages.The planshould include provisions for the purveyor to augment the reclaimed water systemswith other water supply sources to avoid or reduce the severity of shortages orsupply interruptions, strategies to allow seasonal or interruptible reclaimed watercustomers to use their traditional supplies when warranted, or scheduling deliveries(e.g., defined watering schedule).
4.2.6.2 The purveyor shall have a plan for scheduling and/or controllingreclaimed water deliveries to user. Water uses may be scheduled and/or controlledby or coordinated with conservation mandates and local health departmentrequirements.
4.2.7 Retrofitting for reclaimed water service. The purveyor shall conductperiodic review to identify potential customers for retrofitting with reclaimedwater service. Some programs include policies and procedures for voluntary ormandatory connection and/or use，and a plan to facilitate retrofits in the areasdesignated for reclaimed water.
4.2.8Use requirements. Reclaimed water systems may serve either a singleor multiple user types, including residential, commercial, industrial, environmental,and public use.The design and operation of the reclaimed water system may bedifferent for each class of user and should take into account the end user(s) tomaximize reliability to all users.
4.2.8.1 Environmental considerations.Special consideration should begiven to use requirementsspecified forenvironmental protection. Manyapplications, including irrigation, have specific water quality requirements. The effect of these physical and chemical constituents on discharges to groundwater, surface water,crops, and soil should be quantified prior to use.ANSI AWWA G481 pdf download.
