# 38 w Jersey requires that engineering design of water, storm, wastewater and air systens be colabor because within the space

###### Question:

38 w Jersey requires that engineering design of water, storm, wastewater and air systens be colabor because within the space of 800 square miles, live about 3 milion people. This means each person can affect the ar 4u and water resources of another person. To add to the complexity of overlapping resource demands is the institutional complexity of independent municipal jurisdictions. There are over 150 separate municipal sewer and water utilities a separately elected munioipal council and mayor. Therefore, because municipai boundaries do 43 not conform to watersheds 45 safety of Individual 46 This 48 sor airsheds, collaboration is required for the design of stormwater systems, roads, water age systems. The Professional Engineer is licensed to provide that expertice to protect both the health and Is as well as the welfare of the agencies and municipalities that employ them on the analytical techniques to measure the air quality impact of particulates frorm a coal fired power generation plant. For that matter, any discharge through a smokestack. This course also focused: on the s to determine the capacity of a reservolr to meet water supply demands given a seasonal water inflew; on the analytical techniques to determine the assimilative capacity of a river to a 49 variation in surface water inflow: on the analytical techniques to determine the assinm so wastewater discharge; and on the conventionaltechniques to design drinking wate treatment 51 this course offere 52 treatment and distribution systems so that the interconnected system d design concept-find common ground -1. to develop interconnected water supply sources, does not go dry; and 2. to nitrity and denitrify 53 wastewater to minimize the need for unconventional drinking water treatment to prevent nitrete s4 concentrations from entering drinkin g water that serves those same people who discharge the wastewater 55 Problem: In the graphic representation of a Surface Water 56 reservoir watershed and one circle around the watersheds interconnected by pumping stations. Supply Transter Network draw a cirele around each 57 Circle the correct answer and provide backup cakulations 1. What is the approximate diameter of a pipe that trans'ers 100 million gallons per day flowing at a velocity of C 8 teet 10 feet per second? A. 1 foot Show the calculations B. 4 feet 60 61 62 63 2. Is a milligram per liter (mg/) equivalent to: A. a part per billion (ppb) or 8. a part per million (ppm)? 64 65 Show the calculations 3. What is the approximate weight of a 100 milion gallons of water? A. 4000 tons 8. 40,000 tons C. 400,000 E7 Show the calculations and assumptions tons 63 of 10 ppm of chiorine in 100 milioni gailons of water (assume the density of 4. What is the approximate weight 10 ppm of chlorine does not change the density of waterl? Show cakulations 71 72 S. What is the horizontal and vertical scale of the Surface Water Supply Transfer Network? 1" - 1 mile: 1" a 4 miles; 1" 8 miles; 7 6.Crcle the scale AND units (med, cis) for wastewater ? 3, 20 and for water treatment ? 30, 200 76 Conversions for questions 1, 2., 3, & 4. 8.34 pounds -1 gallon of water; 1.54 cubic feet per second 1 milion galans per day, 1 ton - 2000 pounds
