Sec. 567.5. Joint facility rents and expenses

(a) A joint facility for the purpose of this system of accounts is defined as any property occupied or used jointly by the utility and another or others under a definite arrangement whereby the actual costs are shared between or among the parties. Property of the utility occupied or used under a similar definite arrangement between the water department and a coordinate department or departments shall likewise be considered as a joint facility. (See operating revenue instruction, § 566.3.)

(b) When the utility owns the joint facility, any amount received or transferred as reimbursement of operating or maintenance expenses shall be credited to the appropriate operation, maintenance, or clearing account except credits for steam or other power transferred, which shall be entered in account 625, Expenses Transferred—Credit; amounts received or transferred covering depreciation, taxes and interest or return, shall be credited, in the case of another or others, to account 472, Rents from Water Property, and in the case of coordinate departments to account 473, Interdepartmental Rents.

(c) The amount paid by or transferred to the utility for costs of operation and maintenance in connection with occupancy or use of a joint facility owned by another shall be charged to the appropriate operation, maintenance, or clearing account or accounts; the amounts for depreciation, taxes and interest or return shall be charged to the rent account appropriate for the class of property involved.

(d) In the event that joint facilities are used by either party in connection with construction work, credits for the full amount received and charges for the full amount paid, as the case may be, shall be made direct to the construction accounts affected.

(e) These instructions are not intended to cover cases of joint ownership of property when each joint owner bears the cost of operating and maintaining its own property. In such cases the cost of operations and maintenance shall be recorded in the appropriate operation and maintenance accounts even though one of the joint owners operates or maintains the property and bills against other owners for all or a portion of the expenses incurred.

(f) Water supplied by the utility from its own supply to a coordinate department shall be accounted for as provided in operating revenue instruction section 566.3. If the utility desires to charge the appropriate accounts in any of its water operations with the cost of steam or other power used from its own supply, credit therefor shall be made to account 929, Duplicate Charges—Credit.

(g) If the arrangement regarding use of facilities does not provide for the allocation of actual costs, the facilities shall not be considered as joint.

(h) The utility shall be prepared to furnish for each charge or credit the detail thereof and the basis of allocation.
