Yes,
Its a great book. But before you pay be aware its all in Imperial units, not an SI unit in sight. Rather old fashioned in today's world.
If you dont wqant to pay for it you can access it via their website.
If you want a copy enter the Civil Quiz every month and get a prize. These include discounts on books. My discount was USD50, then it doubled because I ordered the book on the day. that made it good value.
The alternative is to download Epanet software and the manual. Epanet is the engine that Haestad uses so all you forego is the user support. This tends tobe salesmen trying to flog you more products anyway.
