Local Water Supply and Treatment Overview
Des Moines Water Works serves about 246,000 people through 94,000 connections using surface water as its source. The system undergoes multiple treatment processes documented by EPA codes, ensuring water quality aligns with regulatory standards. Water flows through this treatment before reaching households, impacting chloramine presence at the tap.
Reading the Public Water System Record as a Homeowner
Chloramine Presence in the System
While the EPA record does not specify chloramine concentrations, the use of advanced treatment processes typically includes chloramine as a disinfectant. This means chloramine is used within the system to keep water safely treated throughout the distribution network.
Other Water Quality Indicators
The record indicates no detectable lead at the 90th percentile in distribution, suggesting effective corrosion control but does not measure chloramine levels directly at individual taps.
Maintenance Rhythm for the C-Series Chloramine (City Water) Filter
Scheduled Filter Renewal
The filter is designed to ship ready to configure and requires routine replacement to maintain effectiveness in reducing chloramine. This replacement cycle depends on household water usage and local water quality conditions, with manufacturer guidelines providing clear timing.
Monitoring Filter Performance
Regular attention to filter condition helps sustain chloramine reduction and protects plumbing and appliances. Tracking changes in water taste or odor can also signal the need for filter renewal.
Additional Concerns for Commercial or Industrial Operators
Volume and Flow Rate Considerations
Larger water volumes and higher flow rates in commercial settings may require treatment capacity beyond typical household filters.
Regulatory Compliance Needs
Commercial users often must document water quality more rigorously, necessitating detailed testing for chloramine and related compounds to meet operational standards.
Household Fixtures and Appliances Affected by Chloramine First
Water-Using Appliances
Devices like coffee makers, humidifiers, and aquariums are sensitive to chloramine and benefit from treated water.
Plumbing Components
Rubber seals and valves in faucets may experience accelerated wear if chloramine is not reduced.
Understanding Certified Laboratory Testing for Chloramine
What the Test Measures
Certified labs can measure chloramine concentration in water samples from your tap, providing data specific to your household.
Interpreting Test Results
Results indicate chloramine presence but do not alone determine water safety or the need for treatment; consider alongside taste, odor, and appliance impact.
