How NaaS Simplifies a Smart Water System Deployment

Driving the adoption of smart water on a widespread scale requires simplicity and cost certainty, both of which can be found in Network as a Service (NaaS) models for AMI. With NaaS, utilities avoid upfront capital costs and ongoing operating expenses and pay a set monthly fee instead.

The unpredictable expense of fixed network infrastructure

Prior to 2014, implementing AMI required utilities to invest in fixed-network infrastructure because cellular-backed solutions weren’t available. With a fixed network, hardware manufacturers tell utilities where to put data collectors—essentially computers tied to antennas—throughout the system to cover the service territory. While the municipality typically has some assets that can be used for placement, such as storage tanks and pump stations with high towers, leasing space or installing poles is often necessary. Additionally, data collectors typically need replacement every seven to 10 years, which can add up quickly.

Along with the lifecycle costs comes the headache of keeping an entire communications network up and running, as most utilities don’t have the appropriate personnel, tools or time. This means utilities often must stretch their budgets to hire more permanent staff or use contractors when help is needed. Although these factors lead to unpredictability in budgeting, traditional fixed networks continue to be rolled out by utilities.

NaaS: A more cost-effective approach for water utilities

When utilities choose a NaaS solution for their fixed network deployment, the hardware manufacturer handles the installation and leasing space, if necessary, as well as monitoring, managing and maintaining the network. Although this can be better for a utility than owning the network, a cellular solution is often even more advantageous.

Cellular-based NaaS is a turnkey solution that includes the communication network as part of the hardware package, so the monthly fees utilities pay don’t need to include a cost for installing and maintaining a network because it’s already in place. This type of agreement can also be extended for the full life of the system, whereas most fixed network NaaS providers won’t offer the same length of contract. As a result, cellular NaaS provides more long-term budget predictability.

Another upside of switching to a cellular NaaS provider is the ability to upgrade to smart meters at a pace or sequence that makes the most sense for the municipality. This can include a phased approach to bring specific routes online over a planned period—starting with commercial and industrial customers, which account for most of the revenue—or simply replacing older meters with smart meters as needed.

Conducting a proper evaluation before upgrading

When comparing NaaS vendors, some key considerations include:

• Pricing Structure: Is there a fixed service unit price over the course of the contract or does the price increase several years into the term?
• Rate of Payback: This will vary based on many site-specific factors, but it should be more accelerated than the rate for a traditional AMI system. Some companies offer ROI calculators to walk municipalities through the calculation before making a commitment.
• Provider Reputation: A key reason that municipalities are uncomfortable with a NaaS contract is that the upside of shedding responsibility comes with the downside of a loss of control. A partner that is trusted and experienced in the industry can alleviate those concerns.

Vendors that offer flexible contract structures to account for funding challenges—the ability to shift costs to an operational budget item—provide additional value to municipalities. This is helpful, as smart water projects often don’t move forward because funding for capital projects is not readily available or is competing internally against other infrastructure projects.
