A couple of issues:
Water/Sewer Rates: Depending on what state your MHP is located you may need the rates you charge your residents approved by the state's Utility Commission; not that big of a deal; or you may be in a state that is regulated exempt. Regardless you should have a clear simple Rate Sheet available to your residents; and attached to all new leases.
Tier Rates: The idea is to promote water conservation and fix plumbing leaks. While you can typically pass through the tiered marginal increasing rates; that mechanics are somewhat cumbersome. The tiered rates are for the whole park, therefore they do not kick in till the whole park reaches the tier point, regardless of individual usage of each MH. So basically when the MHP exceeds the (say) 50,000 gallon tier point then those users exceeding their prorate of 50,000 gallons are charged the marginal increased rate. Enough said: In our 25 years of sub-metering experience, most Utility Commissions would rather approve an average cost per 1,000 gallons applied uniformly, regardless of tiers rates established by the municipal supplier.
