RH2 has completed more than 100 sewer system plan updates, and views comprehensive sewer planning as a complete evaluation of a system. All of the components are analyzed, including structural condition, hydraulic characteristics, financial viability, and wastewater quality, as well as the impacts to treatment systems, the operations and maintenance program, and the capital improvements program. We understand the value of receiving input from client staff and the public during the comprehensive planning process, and work closely with staff members and provide opportunity for public comments to ensure the final plan is a useful tool for guiding day-to-day operations as well as the capital improvements program.
Our comprehensive planning process targets necessary and cost-effective improvements that can be financially implemented and easily understood. The improvements are developed to meet current and anticipated regulations and incorporate enough flexibility to react to the dynamic planning and regulatory process. Engineers calculate future facility sizes by projecting land use and population growth. Once they determine the size and distribution of facilities and what engineering standards and regulations the system must meet, they can prepare accurate cost estimates and design a financing plan to implement the facility improvements.
RH2 analyzes the hydraulic condition of a system by creating a computer model using software specifically developed for this purpose. The model simulates how the system will react to peak flows and how it will react to system growth and alternative routing improvements. The simulation or hydraulic analysis enables the engineer to quickly pinpoint deficiencies and recommend improvements. The model is linked to the AutoCAD database, which can be overlaid onto a computer map of the City’s service area and printed.
The results of the hydraulic analyses are incorporated into the CIP. Facility improvements are ranked and scheduled according to the policy developed by the municipality and based on the financial capability of the rate and loan programs in effect.
The model and mapping become the client’s property upon completion of the project. The interface is very user friendly and requires little training time.Both the model and map provide the client with excellent record keeping and analysis tools for use on a daily basis. For example, the model can be used as part of a certificate of sewer availability program to determine the impacts of a new development on the sewer system and the subsequent need for improvements.
