Part D

Planned activities and affected services sets out processes relating to the long-term planning, short-term planning and reactive activities carried out by the Wholesaler in relation to the provision of Water Services and/or Sewerage Services. Under all these processes the Wholesaler shall notify the Retailer of any planned interruption to supply including any decrease in water pressure to below the applicable minimum standard, which takes place within all or part of its Area and which is reasonably likely to affect the supply to the Retailer's Non-Household Customers.Such notifications shall be by electronic means.

In addition, the Wholesaler shall also notify the Retailer of any planned change to supply, including any change in pressure or change in the composition of water provided, which takes place within all or part of its Area and which is reasonably likely to affect the supply to Eligible Premises which are the subject of Non-Public Health Related Site Specific Arrangements.

The Wholesaler should continue to conduct any public consultations or campaigns which it runs in relation to planned activities affecting its Network and shall not exclude Non-Household Customers from those communications.

The Wholesaler must also ensure that, where it is required to do so (for example when making a Disconnection for the purposes of carrying out works under section 60 of the Water Industry Act 1991) it provides notice to the NonHousehold Customer and makes an alternative supply.

The Retailer shall also notify its Non-Household Customer of any planned interruption to supply (and, in the case of any Non-Public Health Related Site Specific Arrangements, any planned change to supply) covered by this part D which is reasonably likely to affect it, and the Wholesaler and the Retailer shall co-operate to ensure any such notifications are consistent with each other.Such co-operation shall include but is not necessarily limited to following the processes in this part D (Planned activities and affected services).

If, at any time, the Retailer becomes aware of any Drinking Water Supply Change, Sewer Flooding or Other Public Health Risk, it shall follow the twenty-four (24) hour contact arrangements described under heading C (24 hour contact arrangements) of part E (Unplanned events and incidents).

For clarity, this may be at any time before, during or after planned works. If circumstances change in respect of planned activities, the processes at part E (Unplanned events and incidents) may apply.
