1 Scope
This guide has been developed to assist designers in estimating operating and maintenance costs, including environmental considerations through greenhou gas abatement costs, for water and wer designs. All water and wer designs, upgrades, renewals or operational changes require an asssment of life-cycle costs, capital and operating, for all propod options.
This document details values and formulas for network operation and maintenance requirements. It also includes values and tables for incorporating environmental considerations and outlines the process for assigning value to emissions.
Hunter Water should be consulted in determining the operating and maintenance requirements for non-standard networks, such as pressure werage.
2 Annual Network Operation and Maintenance Costs
The following generic annual operation and maintenance cost formulas and tables are to be ud to estimate costs associated with network operations. Alternate data may be ud with prior Hunter Water approval where site/project specific information is available.
2.1 Sewer
Gravity Mains $2872 - 1.13 x DN + 0.00024 x DN2 x L
Rising Mains $700 + 0.0005 x DN2 x L
爱心树读后感
Sewage Pumping Stations $4000 + 2000 x No. of Pumps
DN – pipe nominal diameter (mm)
L – pipeline length (km)
Determine pumping station energy usage from an annual flow of 1.2 x ADWF for all catchments contributing to the system. Pump efficiency determined from the current performance for existing systems or the duty point determined from the manufacturers pump curve.
