• Most piping systems have 25yr life

• Upgrading should include hydrants, curb stops, and main line valving

• Well pumps should be perodically cleaned

• Piping materials should be chosen with water quality in mind.

• Mechanical Filtration

• Ion exchange

• Sequestration

• Corrosion Inhibitors

• Disinfection

Treatment Options

• Mechanical Filtration $5,000-$25,000

• Ion exchange $2,500 - $10,000

• Sequestration $1000 - $2,500

• Corrosion Inhibitors $1000 - $2,500

• Disinfection $1000 - $2,500

• Ongoing cost $300 - $500 per month

Treatment Cost

• Identify your specific problem

• Identify your treatment goal

• Investigate potential adverse affects

• Compare upfront cost with ongoing expense

• Some problems may require more than one technology to solve

Water Treatment Summary

• Water / Sewer Audits

• Leak Detection / Inspection

• Metering (sub-metering)

• Sewerage rebates from metered systems

Revenue Potential Vs. Expenditures


• Comparison to Standards

• Average metered home 130-150 gpd

• Average un-metered home 175 - 200 gpd



• Underground leaks found by visual, sounding, infered

• Home leaks found by individual inspection



• Each home in a community is metered and residents are billed according to their own consumption level


• Meter Types

• Pulse, Encoded Register

• Outside Mechanical / LCD Display

• Touch Reading

• RF Technology


• Meter Billing Options

• Revenue should mirror expenses

• Self generated bills

• Third party billing services including web based services.



• Wastewater charges for water leaks can be a significant short term revenue source.
