They are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the people's needs for water resources in life and production. Water conservancy projects need to build dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways and other different types of hydraulic structures to achieve their goals. Water conservancy projects need to lay a large number of drainage pipes to drain water sources. Drainage pipes are an important part of water conservancy projects and are important channels for building water conservancy projects to control water flow, prevent floods and waterlogging disasters, and regulate and distribute water.
