Top 10 Considerations For Designing And Installing Your Stormwater System
Top 10 Considerations For Designing And Installing Your Stormwater System

Designing an underground stormwater storage system is a unique step in the overall construction process for each site. The size of the inlets and the conveyance pipes are determined by flow rate, elevation, and slope. This information is entered and calculated by stormwater management software to determine the drainage calculation. But many of the measures build upon one another or vary based on different criteria, so it can be a pretty complex process. That’s why we’re going to take a look at the top 10 factors that go into designing and installing one of these systems.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Optimizing Chemical Dosing Reduces Chemical Use While Meeting Effluent TP Limits
    Optimizing Chemical Dosing Reduces Chemical Use While Meeting Effluent TP Limits

    The city of Black River Falls in Wisconsin used chemical treatment with ferric chloride (FeCl3) to achieve their effluent total phosphorus (TP) permit of 1.0 mg/l. Historically, the chemical dosing rate was manually adjusted on a daily basis based on the measured effluent TP concentration. The plant was upgraded with an OSCAR process performance optimizer control system with phosphorus controller, which uses continuous measurement of orthophosphate.

  • Liquid Level/Interface Monitoring In Flocculant/Sludge Control
    Liquid Level/Interface Monitoring In Flocculant/Sludge Control

    Precisely measuring and controlling the mixture of wastewater effluent, flocculants, and sludge is essential to efficient water treatment. The level/interface instruments that support the process liquid measurements must be capable of distinguishing between liquids with varying properties in order to detect the levels where the different liquids interface in the pond or tank.

  • Pilot Studies In North Carolina With Hydrex™ Odor Solutions
    Pilot Studies In North Carolina With Hydrex™ Odor Solutions

    Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H2S atmospheric concentrations of 300-500 ppm. Both clients desired H2S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

  • Sonoma County Improves Sludge Handling With Screw Press Pump Technology
    Sonoma County Improves Sludge Handling With Screw Press Pump Technology

    When California’s Sonoma County Water Agency (SCWA) wanted to improve its sludge solids dewatering as part of a major sludge handling upgrade, they were seeking an alternative to outdated sludge belt press/conveyor technology.

  • Mexican Power Plant Meeting Tough Wastewater Challenges
    Mexican Power Plant Meeting Tough Wastewater Challenges Recovering water for boiler feed makeup can come with many challenges for power stations; however, the level of complexity involved with treatment is raised considerably when having to deal with municipal wastewater. By Geoff Hong, Regional Sales Manager – Water and George Di Falco, Communications Coordinator, Eco-Tec Inc.
  • Fluence’s MABR For Wastewater Treatment features Passive Aeration And Saves Up To 90% On Energy Costs
    Fluence’s MABR For Wastewater Treatment features Passive Aeration And Saves Up To 90% On Energy Costs

    The Bordeaux region of St. Thomas had a pressing need for a wastewater treatment plant that produces high effluent quality. Its existing plant was old and did not meet regulation nor industry standards. Fluence, together with its partner SD&C Inc., built an MABR-based wastewater treatment plant from the ground up, utilizing whatever existing pieces of equipment could be used from the old plant.

  • Air Filter Maintenance: Impact On Efficiency And Machinery Health
    Air Filter Maintenance: Impact On Efficiency And Machinery Health

    In an ideal world, would we not want to eliminate air filters altogether? What keeps us from achieving this is foreign material, detrimental to air, which moves rotating equipment; meanwhile, the process that receives the air sometimes cannot tolerate it.

  • Get More Out of Water Resources Engineering Models
    Get More Out of Water Resources Engineering Models

    The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and conveyed to decision makers and the public.

  • WWTP Overcomes Odor Issue
    WWTP Overcomes Odor Issue

    The City of Crystal Lake is located about 45 miles northwest of Chicago with a population of nearly 45,000 people. Like many wastewater treatment plants, urban sprawl and suburban development puts the Crystal Lake Wastewater Treatment Plant near a host of commercial and residential neighbors, including a high school immediately west of the plant. Plant managers were very forward thinking, and wanted to be good neighbors to those occupying the surrounding area. They wanted to take steps to reduce — and hopefully eliminate completely — any odor issues from the plant.

  • Replacement Vacuum Feeders For Hypo And Bisulfite Boost Disinfection Reliability For WWTP

    The replacement feeders also cut bisulfite consumption by 30 percent and ended the troublesome maintenance burden for instrumentation tech and plant operators.
