Project 5359

Budget

$200,000

Objectives:

• Investigate how residential demand models that incorporate socio-economic factors, climate variables, and/or land use/development patterns are used within utilities, the assumptions they make in their forecasts/models, and if/how they are incorporated into scenario-based demand projections.

• Investigate how different models and approaches can be used for different forecasting and scenario planning needs and to address uncertainties related to socio-economic and climate variables.

• Develop 3-5 case study examples from different regions of the country that demonstrate the use of these methodologies, and identify gaps, new opportunities, and constraints.

• Provide a set of recommendations and guidance to water utilities on what factors could be included in water forecast models, what uncertainties remain, and the budgetary/resource requirements necessary to utilize the method.

Project 5360

Budget

$200,000

Objectives:

• Catalogue alternatives to water shutoffs for non-payment, and evaluate each alternative’s effectiveness and its impact on utility financial sustainability and water service continuity.

• Evaluate the effectiveness of billing practices in helping keep customers from accruing debt that leads to shutoffs.

• Investigate customer behavioral triggers of billing practices, alternatives, and penalties across the income spectrum, and how this may differ across utility sizes.

Objectives:

• Provide an overview of the different types of data centers and their required water, sanitary loads, and energy use based on size and how these impacts may vary based on the type of data center and the cooling tower equipment they use.

• Develop a list of necessary information that a data center should provide to a utility to inform the utility’s infrastructure impact assessments completed as part of a servicing review.

• Develop a list of information a utility should have readily available to support their local economic development agency in their efforts to attract data centers to the community.

• Investigate rate structures and development fees for data centers considering the economic risk of this rapidly growing field and consideration of risk of stranded infrastructure costs should a data center relocate or change water usage patterns.

• Develop utility guidance on how to contract with data centers, establish development fees, and set data center water rates.
