In order to estimate costs and other characteristics of sewer collection and treatment systems, it is necessary to make estimates of future service areas, treatment plant locations, lift stations and trunk line layouts. These locations and configurations are estimated for preliminary planning purposes and should be considered as approximate rather than specific. The objectives are to develop, evaluate, and recommend alternative technical methods for achieving water quality criteria during critical stream conditions. The costs associated with the control strategies are defined in order to allow for a comparison of the alternatives. In order to obtain the final technical plan most beneficial to the 208 Planning Area, alternatives are developed for both the dry weather and wet weather critical conditions. Dry weather alternatives are based on three regionalization concepts for municipal point source wasteloads. The three regionalization concepts are then developed along various treatment themes for controlling wasteloads to the stream; e.g. increasing treatment efficiency, removal of wasteloads through transport or land application techniques. Information is presented first in a Methodology chapter which includes the basic assumptions and analyses utilized throughout the subplan are presented for four hydrologically defined areas; (1) Spring Creek/Cypress Creek/Lake Houston; (2) Clear Creek/Clear Lake, including Armand Bayou and Dickinson Bayou; (3) Houston Ship Channel and tributaries to confluence with the San Jacinto River; and (4) Lower San Jacinto River and Houston Ship Channel below confluence with the San Jacinto River. Each subplan is evaluated for its major impacts including cost, energy utilization, land utilization, and environmental effects. Additionally, its reliability and sensitivity are evaluated.
