The bill establishes a framework for the provision of water service to manufactured home communities and mobile home parks in Iowa. It allows landlords of these communities to opt for direct water service to individual tenants through a written water service agreement with the water system. The bill outlines the responsibilities of both the landlord and the water system, including the landlord's obligation to notify the water system of their choice, comply with the water system's standards for plumbing facilities, and cover the costs associated with installing submeters. The water system is required to inspect existing plumbing and provide necessary specifications, while also establishing direct accounts for tenants to manage their water consumption and billing.

Additionally, the bill stipulates that landlords are jointly responsible for any delinquent charges associated with water service to tenants, and it prohibits the water system from requiring deposits from tenants. The agreement must include terms that ensure the water system's rates and conditions are comparable to those imposed on similar properties. The landlord must also provide documentation of tenants to the water system and notify them of any changes in water service provision. Overall, the bill aims to streamline water service delivery while ensuring compliance and accountability from both landlords and water systems.
