Municipal Drinking Water

Water insights evolved from source to tap.

Save time and money reduce non-revenue water; react faster to changes in your water; and get more accurate results for your municipal drinking water throughout the entire treatment process. Hach’s solutions are designed to make drinking water analysis better, from plant to lab to field, giving you total confidence in the quality of your water.

Hach covers all the drinking water testing parameters that you use to analyze and treat incoming raw water, filtration, disinfection and the distribution system. Click on the icons below to learn more about how Hach helps in each stage of the treatment process for the analysis of drinking water.

Drinking water quality analysis in source water for appropriate pre-treatment

monitor contaminants in source water

Source water can be vulnerable to accidental or intentional contaminants and weather related or seasonal changes. Monitoring the quality of your incoming source water enables you to anticipate changes to the treatment process that are needed to react to storms, algal blooms, industrial discharge, chemical spills, reservoir stratification/destratification, construction activity, sewage spills and other natural or man-made occurrences.

Protect your budget and reduce operating costs, like electricity, chemicals, and sludge with effective monitoring of organics, and inorganic matter. Maintain the correct dosing for coagulants and respective pH adjustments. Test parameters such as: Total Organic Carbon TOC, TOC analyzer, Carbon analyzer, Bacteria in water, and Heterotrophic bacteria.

Optimize filtration with accurate turbidity measurements

filter parameters including turbidity, suspended solids and particle counting

Protect your filters and avoid costly mistakes by monitoring filter performance in municipal water treatment. Keep total output under control, optimizing the amount of water used for backwashing as well as the quality of water before disinfection. Having reliable turbidimeters at the outlet of each filter gives you confidence and peace of mind. Filter parameters include: Turbidity, Suspended Solids, Alkalinity, and Particle Counting.

Not only is monitoring turbidity effluent required for regulatory compliance, it helps to ensure the final product is safe for public consumption. In addition to meeting regulatory requirements, monitoring turbidity is also beneficial for optimizing filter performance, establishing filter backwash cycles, and detecting filter breakthrough.

Improve control of your disinfection process

save money on your disinfection process

Save money on resources during your disinfection process by pinpointing your resource needs. Disinfection is a complex process, affected by a variety of factors. If your water has a high level of organics, you risk forming carcinogenic by-products. If you do not add enough disinfectant, you may risk microbiological growth. A wide range of analytical methods and instrumentation is available to address the specific needs of each unique plant and process, including chlorination, chloramination and UV disinfection.

Regardless of the type of disinfectant used, analytical testing can help you comply with regulations, maximize disinfection efficiency, determine adequate CT credits, optimize chemical feed pump rates, reduce the risk of disinfection byproducts, and control taste and odor issues.

Monitor water quality in the distribution system

save money on your disinfection process

By monitoring treated water within the water distribution system network, you can identify potential problems that pose risks to public health and threaten regulatory compliance. Once treated water leaves the plant, it can come in contact with various components within the distribution system that potentially alter the quality of the water before it reaches consumers. This makes it hard to guarantee quality for the customer and emphasizes the importance of testing samples in the field.

Hach helps you monitor specific parameters in the distribution system to ensure delivery of safe drinking water to the community. Additional monitoring can also provide early indication of nitrification issues, pH, alkalinity, hardness, conductivity, water infiltration, line breaks, extended water age, or potential security violations.
