ABSTRACT

This chapter outlines new modules developed for WIMS: the Sewer Flow Analysis System (SFAS) and the Sewer Connection Application System (SCAS). The City and County of Honolulu, Department of Wastewater Management (DWWM) is charged with the wastewater service of approximately 900,000 persons living on the Island of Oahu. Effective management of the wastewater system by DWWM is being aided through construction of an island-wide wastewater information management system (WIMS). The SFAS module and hydraulic model will be used for planning new projects, evaluation of existing system hydraulics and capacity, and to enhance infiltration and inflow reduction analysis. SCAS will allow the City to process sewer'connection application forms, store and track the sewer application data, and effectively manage the system by producing warnings whenever sewer capacity is reaching critical levels. When capacity reaches pre-set limits, notification of these triggering flows is automatically issued and planning functions for correction of the capacity deficiencies can be started.
