Lakota WWTP UV Disinfection System Upgrade, Lakehaven Water & Sewer District

About

In partnership with Trane, an energy services company, BHC designed and helped implement improvements to the ultraviolet (UV) disinfection system at the Lakota WWTP.  The old UV system had become inefficient and was extremely labor intensive, requiring frequent manual cleaning of the numerous UV lamps.  The new UV disinfection system provides UV dose pacing for improved energy efficiency, automated cleaning of the UV lamps, and fewer higher efficiency lamps.  Modifications were made to existing concrete channels to install the new UV disinfection system, which included extension of the channels to allow future installation of twice as many UV banks.  This provides flexibility to add UV banks to meet potential stricter discharge limits, accommodate growth, and/or further increase system redundancy.

Features:

  • Drastically reduced labor requirements for maintenance of the UV disinfection system
  • Reduced energy consumption and increased disinfection performance
  • Design-build delivery method substantially reduced costs for the temporary chemical disinfection being used to supplement the old under-performing UV disinfection system

Lacey Sewer Plan

About

The City of Lacey’s topography consists of rolling terrain that has resulted in 47 lift stations, 2,500 septic tank effluent pump (STEP) systems, numerous grinder pumps, and gravity sewers to serve the residents of the City. BHC developed a comprehensive system wide dynamic model to determine deficiencies in the existing system, plan for system expansion, and review opportunities for lift station abandonment. The STEP system was represented in the model by clustered pump stations to mimic changes in flow and pressure without adding unnecessary complexity and adversely impacting model runtimes. The model was calibrated using measured flow and STEP system pressure data. Because of the large number of pressurized systems needed to overcome the terrain, future sewer expansions could connect to several existing trunks, allowing the City to optimize the capacity of their existing infrastructure. BHC analyzed several alternatives for sewer expansion in order to come up with a recommendation to optimize the capacity of the existing piping and pumps. After reviewing the results for the STEP expansion alternatives, an efficient, prioritized CIP was developed to help the City address existing capacity concerns and plan appropriately for growth.

Features:

  • InfoSWMM model of a sewer with 47 pump stations and 2,500 STEP systems
  • Modeling used to optimize existing infrastructure and minimize capital costs in future system expansion
  • Prioritized capital improvement program

The more efficient and accurate model was used to analyze system deficiencies; identify requirements for new developments; and develop capital improvement plan.

Features:

  • Combined model provides more efficient analysis
  • Parcel-by-parcel flow estimates enhance accuracy of model
  • Identification of developer-driven improvements reduced long-term capital costs for City

Comprehensive General Sewer Plan Update, Clark Regional Wastewater District

About

Clark Regional Wastewater District is one of the largest sewer districts in the state, currently providing sewer service to nearly 100,000 people, 30,000 employees, 25,000 students, and 300 acres of industrial users. The District service area extends for more than 50 square miles and includes all or portions of three cities (Cities of Ridgefield, Battle Ground, and Vancouver) and unincorporated Clark County. The District owns and maintains more than 600 miles of sewer pipes, 60 pump stations, and 800 individual STEP systems. Growth and development within the District service area have been very robust and among the healthiest in the state. As a result, an aggressive Capital Improvements Program (CIP) to support this economic development and population growth was developed as part of the Comprehensive General Sewer Plan (Plan). The Plan was used as an effective tool in sizing and extending the sewer system to the unserved areas while accommodating growth in existing service areas.

Regulator R4/R39 Hydraulic Analysis and Upgrades

About

The City of Everett is working towards compliance of its combined sewer outfalls to meet Department of Ecology requirements of no more than one overflow per year on average over a 20-year period. This project aimed to modify two existing regulator weirs to divert more flow through their Summit Interceptor and less flow towards the outfalls. The initial phase included modeling of several alternatives to optimize weir heights and configurations, and included replacement of one regulator and modifications of another. The new regulator was designed to allow for stormwater separation in the upstream basin in the future and improved maintenance access. The completed project has reduced overflows and the outfalls are now at or near compliance.

Features:

  • InfoSWMM model of a combined sewer
  • Modeling used to optimize existing infrastructure and minimize capital costs
  • Improved access and maintenance

Wastewater System Analysis, Seattle Public Utilities

About

Project engineer responsible for calibration of the sewer collection system model and analysis of north central and northeast Seattle using the PCSWMM hydraulic model. The model included both combined and separated sewers and was calibrated to flow meter data collected as part of the project. Model hydrology was calibrated and included groundwater to account for sewer response to rainfall events during different seasons. After calibration was completed, a design storm accounting for climate change was used to define undersized pipes. The model was then iterated that upsizing pipes would not drive capacity problems downstream. After this process was finalized, hydraulically connected problem areas were defined to help SPU prioritize a capital improvement program.
