Wahaso’s experience and leading edge analytic tools are used to develop a custom system design to meet the unique characteristics of each building or project.Scoping Steps:1. Consultation2. Analysis of Supplies & Demand3. Cistern Modeling4. System Concept5. System BudgetDesign & Engineering. Our engineers draw on 30 years of practical experience designing water purification systems. Our designs integrate industry-standard components and Wahaso proprietary subcomponents and controls to deliver efficient and reliable systems. We provide 2D & 3D CAD drawings that can be integrated directly into building specifications.Fabrication. Our comprehensive engineered designs are transformed into working systems in our fabrication facility. Components are assembled and connected on skids and pretested before delivery to the job site.WAHASO SuPPORTS THE ENTIRE SYSTEM DESIGN & BuILD PROCESSEstimated Monthly Greywater Supply & Demand(Gallons) 338,400 349,680 338,400 349,680 350,000 400,000  ( )314,712  315,840 279,744 270,720 300,000 209,808 200,000 250,000 87 420139,872 87 663101,022 129,971 119,999 89,094 109,161 102,538 128,177 110,850 100 000150,000 84,600  87,420 79,564  87,663 81,085 59,801 50,000 100,000 -January February March April May June July August September October November DecemberFlushing Demand Irrigation Demand Total Demand Total SupplyProject:Location:Water Sources:Water Uses: Analysis Date: 12/30/2011Cistern Size% of Total Demand Met Non-Potable Gallons UsedGallons Change from Previous IncrementRain Event Size Capableof Being Handled (inches):5,000 52.45% 227,422-2/510,000 71.40% 309,61282,1904/515,000 81.21% 352,16342,5511 1/520,000 86.77% 376,25224,0891 3/525,000 89.88% 389,75213,501230,000 92.31% 400,28010,5272 3/835,000 94.01% 407,6287,3482 7/940,000 95.28% 413,1645,5363 1/645,000 96.18% 417,0453,8823 4/750,000 96.58% 418,8081,763455,000 96.97% 420,4751,6674 1/360,000 97.35% 422,1421,6674 3/465,000 97.74% 423,8081,6675 1/670,000 98.12% 425,4751,6675 5/9RainwaterToilet FlushingHavelock, NCCherry Point BEQ 136Wahaso's proprietary cistern size optimization model evaluates a range of potential cistern size options to help customers understand the trade-off between storage capacity and the annual savings of municipal water replaced by non-potable sources on-site. Wahaso's model uses six years of actual daily precipitation history for the project location to determine how each cistern option would have performed under actual local conditions day by day. As cistern size increases, a larger percentage of demand can be met from the non-potable source, but there are diminishing returns as the cistern grows. Wahaso's model accurately predicts the average annual water savings at each cistern size so that clients can understand the cost/savings trade off. We then recommend a cistern configuration to optimize the efficiency of the proposed system.Custom Cistern Optimization Modeling from Wahaso75,000 98.51% 427,1421,667680,000 98.89% 428,8081,6676 1/3Table - 1Table - 2The tables above illustrate the effect of cistern size on the total demand met with the non-potable water supply. In Table-1, Column 4 shows the diminishing return in savings as the cistern size increases. The last column of Table-1 shows the maximum rain event size in inches that the empty cistern could handle. This number is important because we will lose all rain amounts greater than this once this event size occurs. The red marker on Table-2 indicates the % of total demand met by a cistern of an infinite size. This is the maximum possible "% of total demand met" and allows for useful comparisons to be made to the range of cistern sizes. 52.4%71.4%81.2%86.8%89.9%92.3%94.0% 95.3% 96.2%96.6% 97.0%97.4% 97.7%98.1% 98.5%98.9% 100.0%0.00%20.00%40.00%60.00%80.00%100.00%120.00%5,00010,00015,00020,00025,00030,00035,00040,00045,00050,00055,00060,00065,00070,00075,00080,000% of Total Demand MetCopyright 2011 - Water Harvesting Solutions, Inc.12/30/2011SCOPINGDESIGN & SPECIFICATIONSFABRICATIONTRAINING & SERVICEINSTALLATION & TESTINGInstallation & TestingWahaso operations teams work on-site with the installing contractor to make sure a system installs and operates properly.Training & ServiceWe include training for the building staff and a one year warranty on the entire system to ensure that it operates as designed.
