Many environmental-conscious countries have already started to limit water usage for a sustainable future. Prince’s has begun an efficient use of water for irrigation. With a strong background in plants and landscape maintenance, we can provide professional input and practices for irrigation based on specific situations.
Irrigation can be manual, semi-automatic, or fully automatic. For manual watering, we can provide irrigation advice on the quantity, frequency, and method for a specific site and plant conditions. For semi-automatic and automatic irrigation, we design and install different irrigation systems including drip and sprinkler systems.
We also provide advice on fertigation and chemigation. Fertigation is an automatic system to apply liquid fertilizer while chemigation is an automatic system to apply liquid insecticide and fungicide.
We give assurance on our projects for best quality and service. Together with our clients and partners, we can work together for our sustainable and bright future.
Our team of irrigation specialists can provide professional consultation to any of our clients’ needs. With proper advice from our team, we ensure that we may be able to provide the suitable irrigation system you require.
Our team of qualified designers may assist in developing an efficient and sustainable irrigation system, may it be in corporate offices, commercial, private and public areas, or homes.
Our team undergoes rigorous training and development to keep up with the current trends and technologies in irrigation systems. Equipped with diverse experiences from a wide variety of projects, the performance and professionalism of our team may be assured.
To ensure that the system is in its optimum functionality, performance and efficiency, we highly recommend irrigation maintenance. It includes all irrigation- related issues, which includes but not limited to technical support, hardware / software repair, and regular maintenance which can be scheduled monthly or quarterly. Here’s a sample of our Irrigation Maintenance Report.
The irrigation system can be on a rental basis and shall be dismantled and taken back once the contract period has been completed. Maintenance includes flushing of laterals, checking drippers, replacement of emitters when necessary, fixing the leaks in the irrigation system, replacement of lateral LDPE fittings when there is crack or breakages in the fittings, timer lateral fliter cleaning, and other irrigation items we have installed.
What kind of Irrigation system should I use?
Prince’s irrigation engineer will be able to advise the best system given the project specifications – ie plant spacing, and plant type, etc.
Why use dripper system?
Drippers allow water to be delivered directly to the plant root zone.
Direct application to plants – especially when wider spaced
Reduces water wastage
Limits overspray onto buildings, walkways, etc
Minimizes risk of mosquito breeding
Reduces water loss through evaporation
Design flexibility – can take water directly to the plant
Avoids fungal infections in susceptible plants
Different emitters are used to ensure watering needs of different plants are met e.g., 2 to 8 liters per hour drippers. (A “spider” system can also be used in conjunction with a dripper to increase the accuracy of water application.)
Why use sprinkler system?
When plants are very small
Plants are very close together
When there is a shallow root zone
What is the drip irrigation operation pressure?
It varies from 1 bar to 1.5 bars depending on the design.
What is the sprinkler irrigation operating pressure?
It varies from 2 bars to 3.5 bars depending on the type of sprinklers.
What is PUB?
PUB stands for Public Utilities Board. Standard PUB water pressure is 3 to 3.5 bars.
Why do we need to regulate the pressure in the system?
If the pressure is more than the designated pressure, the velocity of the water in the system is high and the components may become loose or fall out during operation/ or the system may develop leaks.
How do we regulate the pressure?
By using a gate valve/pressure regulating valve and a pressure gauge in succession. Increasing or decreasing the pressure on the pressure gauge is done by adjusting the gate valve/ pressure regulating valve.
When is zoning required?
For larger projects, zoning might be required when the area is divided and watered at different times.
Area to be irrigated is large
Dripper discharge is high (l/hr)
Water availability is low
When is a pump required?
When discharge and pressure required is higher than available pressure.
Why is electricity required?
Electricity is needed when a pump is used to pump water into the system.
How is fertilizer applied ?
Liquid fertilizer is applied via the irrigation system using a fertigator / fertigation pump/ venturi assembly or a dosatron.
What fertilizer is used?
The type of fertilizer applied depends on the plant species. Nitrogen fertilizer is good for vegetative growth, and phosphate and potash are often used for the root growth and flowering. An all-round fertilizer is generally used with added micronutrients.
When is a tank required?
If the water quantity and pressure is not enough to supply the entire system, then a tank is required to store sufficient water for pumping
A tank is also used to avoid pumping directly from a PUB outlet
What will an irrigation system cost?
Different system requirements will influence the cost of the system – eg whether a tank is needed, how many zones, type of system, etc.
What kind of maintenance is required for Irrigation systems?
Removal of Blockages, cleaning of filters and drippers/ sprinklers, flushing of lateral lines ensuring all plants are getting adequate water.
