Knowledge Base Software Water ANALYSIS OF FLUID HANDLING NETWORKS Water is a program for the full analysis and extended time simulation of fluid handling networks. It includes items such as reservoirs, pressure release chambers, pump stations with multiple pumps, valves and all pipe types that are fully editable and can link to external consumption data tables. Water losses can be determined based on a number of factors.

DEMAND PATTERNS FOR LARGE CITIES, VILLAGES & RURAL COMMUNITIES The demand for water in a water supply system varies with time (the usual terms are hourly and seasonal fluctuation in demand or in consumption). The daily water demand distribution is modelled by means of hourly coefficients, that is the water use in any particular hour of the day, is given as a ratio of the daily average. The demands may be multiplied by the seasonal peak factor, if appropriate. This will have the effect of increasing all the demand values by the seasonal peak factor. Typically, hotels would experience variation in water demand during the holiday season. In rural areas the seasonal increase in water usage would correspond with the dry period etc.

LINK EXTERNAL DATA TABLES SUCH AS CONSUMPTION AND TARIFF DETAILS Import data from various sources such as ASCII tables, spreadsheets, DBase or MS Access tables as well as DWG/DXF files. Attach external water consumption tables and compare the measured usage to the modelled consumption to calibrate the demand or identify problem areas in the network.

---

ADVANCED ANALYSIS OPTIONS The analysis may be based on the average, minimum or peak demand with an optional seasonal peak factor. Advanced analysis options such as linking the consumption to pressure are supported.

---

CUSTOMIZABLE PIPE DATABASE WITH DEFINABLE PIPE TYPES & SIZES The Pipe Catalogue contains a user-definable list of pipe types and sizes with attributes for maximum pressure and roughness (friction losses).

---

PUMP STATIONS WITH UP TO 8 PUMPS IN PARALLEL WITH VARIOUS CONTROLS Up to 8 pumps may be handled in each pump station. Multiple pumps are configured in parallel. Pumps may be controlled by pressure, reservoir water level or be time-based (on/off at certain times). Pumps can be configured as sump pumps with a defined pump elevation or as an inline booster which assumes the pipe level.

---

PUMP CATALOGUE The Pump Catalogue contains a list of available pumps. You may view the pump curve and details of every pump in the catalogue. The pump curve page will show the relationship between the flow, the head and the efficiency of the selected pump.

---

RESERVOIRS WITH INLET/OUTLET CONTROL Reservoirs may be specified with full and floor supply levels, storage-depth profile, capacity and inlet and outlet pipes which are controlled by inlet valves operating at specified water levels. There is no limit to the capacity of a reservoir. Dams may be modelled by entering large capacity values.

---

MULTIPLE VALVE TYPES The program supports multiple valve types to regulate the flow including valves to reduce or sustain pressure, or that control the flow based on water level.

---

DISPLAY RESULTS GRAPHICALLY, IN TABLES OR ON TIME-BASED CURVES Display the results of an analysis graphically by colour according to calculated results, in tables at specified time increments using the Results browser, or on time-based curves displaying flow, velocity, head loss or hydraulic gradient.

---

HYDRAULIC AND PRESSURE CONTOUR PLOTTING Hydraulic grade contours are generated contours created using pressures as modelled at the time of creation. After contours have been generated it is possible to use different display options as for any other generated contour. It is also possible to combine pressure contours with height shading or slope shading.

---

SABS 1200 QUANTITIES WITH BEDDING MATERIAL/SELECTED BACKFILL There are various default bedding classes included. Any value may be changed, and the diagram will update to graphically show the changes. Clicking on the Default button will reset all the options back to the default SABS 1200 values for the specific bedding class.

---

CROSSING SERVICES You can create multiple databases which can contain information regarding crossing services, for example sewer pipes, stormwater culverts, electrical layouts, telecommunication cables etc. The crossing services will be displayed on the vertical alignment editor as well as the layout plan and long section.

---

CULVERT CLASH ANALYSIS WITH CROSSING SERVICES This function checks for clashes between any two services such as sewer, storm, water, roads or other services defined in the crossing services. Problem areas are displayed on the layout drawing and the longitudinal section window can be opened to display a long section of the chosen branch as well as the crossing services. You may then adjust the invert levels and slopes of the affected culverts.

---

GENERATES LAYOUT PLAN WITH PIPE SCHEDULE AND LONG SECTIONS Production drawings such as plans, cross sections and long sections with title blocks and company logos etc can be created with little or no CAD editing. The layout of production drawings is completely customizable according to your specific company standards. Crossing services from the other modules can also automatically be displayed on plans, long and cross sections.
