NOTES:
1. THE SERVICES INFORMATION INDICATED ON THIS DRAWING IS BASED ON FIELD OBSERVATIONS
AND DETAILS PROVIDED BY SERVICE AUTHORITIES. DPTI, ITS SERVANTS OR AGENTS SHALL NOT BE
LIABLE FOR ANY LOSS OR DAMAGE CAUSED BY THE USE OF THIS SERVICES INFORMATION .
THIS DESIGN MAY INCLUDE THE POSSIBILITY OF SERVICE CONFLICT AND / OR ENCROACHMENT
WITHIN SAFETY CLEARANCES REQUIRING ASSESSMENT AND APPROVAL BY THE OFFICE OF
TECHNICAL REGULATOR AND SERVICES AUTHORITIES.
IF DURING CONSTRUCTION IT IS FOUND TO BE WITHIN 2 METRES OF ETSA SERVICES, FURTHER
INFORMATION TO BE SOUGHT (BEFORE WORK CONTINUES).
2. A SERVICE REDUCED LEVEL (R.L.) HAS BEEN PROVIDED WHERE THE SERVICE HAS BEEN DEPTHED.
WHEN PROVIDED AT OTHER LOCATIONS SERVICE R.L.'s ARE INDICATED AS INTERPOLATED.
3. THE DESIGN AVERAGE RECURRENCE INTERVAL (ARI) FOR DRAINAGE OF ROAD PAVEMENT IS 5
YEARS.
4. THE AVERAGE RECURRENCE INTERVAL (ARI) DRAINAGE DESIGN FLOW 'Q' IN CUBIC METRES PER
SECOND IS SHOWN ADJACENT TO THE HYDRAULIC GRADE LINE AS A VALUE ONLY.
AT CRITICAL LOCATIONS REQUIRING DEVIATION FROM THE STANDARD, THE DESIGN STANDARD
AND FLOW ARE SHOWN E.G. Q10 = 0.5.
