IDP (Irrigation Driven Pump)

Turf Drain Mini-IDPThe Mini IDP is a revolutionary concept in golf course drainage. The patent pending system is a hybrid of technologies that combines the best of the patented Turf Drain Siphon System, along with the uniqueness of Turf Drain Irrigation Driven Pumps. The applications are endless.

It can be installed in a low lying fairway where there is “no place to take the water.” With the Mini IDP, you can create a pumped elevation in that fairway, and in many cases, use the existing shallow corrugated pipe as your relief.

If you have a pot bunker, or bunker where the sub-grade is at lake level and won’t properly drain, install it either inside or outside of the bunker, and create all of the relief you need. Never build a green again that drains to a dry well. Even use it to reduce the installation of expensive curtain drains in mountain courses.

Mini IDP

Models can be custom built that collect the spring fed water 20 feet below the surface, yet transport the water in a pipe installed as little as 18″ below the surface.

There is no need to run an electrical supply to the pump. You don’t even need to run a wire to the controller for valve control. Everything is contained in the patented Perma Basin, and turns on and off as needed without any power source. In addition, the critical components of the unit can be serviced and replaced from above. Just remove the grate and access all of the moving parts.

Drainage Depth and the Mini IDP

Why Is The Mini IDP So Valuable?

TDA has done hundreds of drainage plans on some of the best golf courses in America. From that experience, we have learned that when it comes to creating firm playing conditions, the depth of the drainage is the most important factor. If an area needs 100 feet of seepage drainage when graded to a two foot deep relief, we can achieve the same effect with 60 feet of seepage drainage, if it is a four foot deep relief; and use as little as 40 feet, if it is a six foot deep relief. The reason is that the deeper the drainage, the wider the influence of that drainage on the water table.

Irrigation Driven Pumps (IDP)

Irrigation-Driven Pump ready to backfill

Irrigation Driven Pumps (IDP), an exclusive of TDA, can be used in remote areas of your course when the use of an electrical pump would require expensive new electrical service. This pump uses the energy of the irrigation system to pump drainage water from a sump. These pumps are low cost and have no moving parts. They are simple to maintain.


The pump uses the energy of the irrigation system to pump drainage water. The pump is placed inside of a sump that has a float in the bottom. When the water level in the sump rises, the float opens a standard 2” irrigation valve that has been placed in line between your irrigation system and the Turf Drain Irrigation Driven Pump. By opening the valve, the water of the irrigation system flows through the pump and creates a vacuum (venturi) that sucks the water out of the sump. The amount of the water pumped will vary, as it would with any pump based on the height and distance that the water is being moved.

Irrigation-Driven Pump (overhead)

A typical example for our basic model would be as follows: a pump placed inside of a 6 foot deep sump discharging the water 200 feet, would pump 140 GPM of drainage water from the sump for every 100 GPM of irrigation water that is being pumped through the system. Therefore, the discharge line would carry 240 GPM to the exit point. The pump itself has no moving parts, although the set-up does require an irrigation valve and a float. The pump can be easily serviced and cleaned. Note the unions that are at each end of the pump. This allows you to remove the pump within minutes, if cleaning is required.
