Working With Some Landscaping Sprinklers

By Judy Sullivan


A good landscape design will serve a great role towards increasing the value of any real estate property. The current efforts to put in place water conservation policies are aimed at getting rid of designs with a careless distribution of landscaping sprinklers that lead to wastage of the scarce resource. The biggest challenge for the designer is to understand and apply the hydraulics of the water to be used for irrigation.

Initially, the static pressure of the fluid in the reservoir being utilized must be determined before the designer starts his calculations. Though it is tempting to assume the anticipated values, this approach may lead to design errors that have a negative impact on the system performance. The plan should try to make allowances for fluctuations in pressure values all year round or in the near future when the existing supply will be shared among more premises.

The choice of appropriate sprinklers largely depends on the financial capabilities of the owner among other factors. Rotating models are preferred for large open fields because of their far reaching distribution. Most of them are moved to a different location when conducting maintenance procedures. Popup varieties are beneath the ground surface when not irrigating and are thus safe from mowing equipment.

In case you realize that your supply lacks adequate pressure for a sprinkler consider using sprayers. These installations are ideal for fitting in the far off corners where the former are least effective. In nursery beds, strong jets will uproot seedlings so drip irrigation is the most appropriate technique. One thing you should strive to avoid is watering to the extent of creating runoff.

It must be appreciated that runoff exposes plant roots and washes away commercial additives that you have applied. Watering at midday or using sprayers that atomize water into fine mists will lead to evaporative losses. Irrigating in the evening is also to be avoided as wet plants are exposed to disease during the night. The best practice is to irrigate early in the morning so that plants make maximum use of available moisture as their uptake rate increases during the day.

Operation valves must be situated within easy reach by the operator. Underground valves have to be encased in special covered boxes that can be opened for servicing. In case manual valves are installed, consider fitting them in a manner that will allow the operator to work them without getting doused by the working sprinkler.

A single lateral conduit that is to serve a number of sprinklers should be fed from the midpoint to support uniform flow. You could save on the water bill by harvesting rainwater into a reservoir on your premises. All designers must adapt their work to the anticipated irrigation times.

Most golf courses have to be irrigated at night to avoid disrupting business the next day. The water window is a description of the watering times and is bound to differ with the applications. Landscaping sprinklers designing is an engaging activity that has to involve topology, flora and human element studies.
