The Town s Water System Master Plan, completed in March 2000, includes a computer model of the Town s water distribution system. Engineers used this model to confirm that the Town s water distribution system will be capable of meeting all domestic and emergency water needs. This model was calibrated and verified with extensive field testing of the existing water distribution system. In addition, Town Fire Department and Utility personnel regularly perform maintenance and conduct field tests in the distribution system to confirm peak flow performance. The Cary Fire Department performs regular risk assessments, including fire flow tests, throughout their service area to ensure adequate availability of water for fire flow.
Water pressure is only one of several criteria used by insurance rating services .
Residential customers should not be impacted by the change in system pressure. Even with the new lower pressures, the delivery pressure and water volume available from the Town s distribution system will equal or exceed National Fire Protection standards. There may be, however, some affect on commercial customers with calculated sprinkler systems. These customers will need to perform individual engineering evaluations to determine whether they will need to add supplemental equipment such as booster pumps. Their insurance premiums would only be affected if they failed to make recommended improvements.
