The Drainage Plumbing Diagram (DPD) system used for purchasing DPDs will be upgraded next week. The enhanced system will work the same way but will provide a shopping cart feature to allow for multiple purchases and overall improved delivery.

The upgrade will take one hour and the DPD search function will be down during this time. It is proposed to occur next week and will be outside of office hours.
