"Smart Planning Wireless and Water Public Utility Facilities Act"; incentivizes placement of wireless communications equipment on water public utility towers.

This bill allows investor-owned water utilities in New Jersey to lease space on their water towers to wireless providers for equipment installation. It requires water utilities to offer non-discriminatory access to tower space, with exceptions only for safety or structural concerns. The key provision treats 50% of rental income from these leases as "above-the-line" income for rate cases, meaning it directly affects how water utility rates are calculated and approved by the Board of Public Utilities. It directly impacts regulated water companies (like Jersey Water) and wireless service providers seeking tower space.
