Irrigation System In Singapore

A Sprinkler system is a form of an irrigation system which is commonly found in golf courses and horse tracks. It is recommended for turf area.
Fundamentally, there are six major components of an automatic sprinkler system. They comprise of:

Water source:
– Tanks, ponds, water well, river

Irrigation pumping unit:
– A pumping unit will work as per the instruction of an irrigation controller. A pumping unit contains a water pump, pressure switch, water top-up mechanism, control panel

Irrigation controller:
– This will be the brain of the system which speaks to the control valves, telling them when and how long to supply water to the sprinklers. The sprinklers will then direct and control the water applied to the landscape automatically. The controller also provides a signal to the pumping unit for on and off. It can also work with various sensors like a rain sensor and a water sensor and It helps to save water automatically as per the plant requirement.

Water conveying pipes:
– uPVC or H.D.P.E. pipes are used for conveying water from source to sprinkler.

Solenoid valve:
– The purpose of a valve is to control a group of sprinklers which is called a watering station. According to how each plant species’ water requirements are and are arranged, the stations are generally laid out and installed. The species with most water requirements will be placed within the landscape and hence, allowing it to have a maximum amount of water supply. Each valve is tied to a numbered station within the controller, classifying it as Station 1, Station 2, Station 3 etc. The controller will operate the valves systematically. Which means, Station 1 will water thoroughly before Station 2 starts. This process is called the watering cycle. The controller can store memories which allows the system to operate automatically and precisely how long and how the stations will receive watering.

Sprinklers:
– Sprinklers are in various types — micro-sprinklers, impact sprinklers, rotors, pop up sprinklers and rain guns. Selection sprinkler selection will do as per the plant specious, planting patterns.

A drip system uses the scientific method of irrigation carrying desired water and nutrients directly to the root zone of the plant, drop by drop.

Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants.

The goal is to place water directly into the root zone and minimise evaporation. Drip irrigation systems distribute water through a network of valves, pipes, tubing, and emitters.

It delivers water and nutrients directly to the plant’s roots, in the right amounts, at the right time, so each plant gets exactly what it needs, when it needs it, to grow optimally. Drip irrigation is known to be the most efficient irrigation methods, with 100% water use efficiency.

COMPONENTS OF A CENTRALISED AUTO DRIP IRRIGATION SYSTEM:

Water sources:
Tanks, ponds, water well, river

Irrigation pumping unit:
A pumping unit will work as per the instruction of an irrigation controller. A pumping unit contains a water pump, pressure switch, water top-up mechanism, and a control panel.

Irrigation controller:
This is the brain of the system which instructs the control valves when and how long to supply water to the drip lines. The drip lines will then direct and control the water applied to the landscape. The controller also provides a signal to pumping unit for on and off. The controller can work with various sensors like a rain sensor and a water sensor, and helps conserve water by limiting the amount of water used according to the individual plant requirements. It helps to save water automatically as per the plant requirement.

Water conveying pipes:
uPVC or H.D.P.E. pipes are used for conveying water from source to sprinkler

Solenoid valve:
The purpose of a valve is to control drip irrigation, which is called a watering station. According to how each plant species’ water requirements are and are arranged, the stations are generally laid out and installed. The species with most water requirements will be placed within the landscape and hence, allowing it to have a maximum amount of water supply. Each valve is tied to a numbered station within the controller, classifying it as Station 1, Station 2, Station 3 etc. The controller will operate the valves systematically. Which means, Station 1 will water thoroughly before Station 2 starts. This process is called the watering cycle. The controller can store memories which allows the system to operate automatically and precisely how long and how the stations will receive watering.

Drip lines:
Drip lines are mainly two types of online drip and inline drip, it allows water to deliver the land by drop by drop

COMPONENTS OF A DECENTRALISED AUTO DRIP IRRIGATION SYSTEM:

Water Tap Point
It is a water inlet inside/beside the landscape area. Expected water pressure is 2.5 bar. The minimum required is 2 bar for better performance.

Double Tap
Used to T.E.E. off the water flow into different purpose one connection is going to drip irrigation purpose. One point is used for connecting the hose for manual irrigation, floor cleaning etc.

Double Check Valve
A dual non-return valve that ensures there is no backflow of water from the drip system to water lines. It prevents water contamination in water lines.

Irrigation Controller:
(Power source: Alkaline battery)
This is the electronic device directly connected in the water point. We can set a daily/weekly watering schedule. Here, we can choose the watering days, time, duration in each programme. The device will deliver water to the drip lines as per the given programme and the controller valve is opened and closed by an electric pulse. The electric pulse will be generated as per set up in the programme.

Drip lines:
Drip lines are mainly two types of online drip, and inline drip, it allows water to deliver the land by drop by drop

A watering program is a system which is deposited in a controller, and it necessitates three basic instructions to operate automatically:

• Days to water – MON TO SUN

• When to water- PROGRAM START TIME

• Duration to water- STATION RUN TIME

The cost differs extensively depending on the brands of the components you select. There are premium brands out in the market, and there are also economically affordable brands.

However, it is always best to seek advice from an irrigation specialist and let them give you some options to choose from.

The sole purpose of having the irrigation system is to be hands-free for your landscape. You should not assume that buying a premium brand will give you a longer-lasting irrigation system.

You may spend $500 for a simple tap timer controller, backflow to stop water from getting back to the water source, driplines, and drip-line accessories. You may spend $5,000 to have the irrigation system for a broader landscape.

It all depends on the size of the landscape, your budget and as well as how experienced your irrigation specialist is. Designing an irrigation system is very flexible, allowing you to select the components used based on your budget.

Yes, different layouts of plants in the landscape have different watering requirements. For example, lawns, shrubs, hanging baskets and borders all require a different amount of water.

Also, the equipment that is being used to water these areas operates at various water pressures and applies water at several rates. Having separated zones will allow these areas to be watered most effectively and economically.

Zoning is necessary when there is a limited size of water source because there we can get enough time to refill the tank as per the requirement.

No, the whole idea of an Auto Irrigation System is to offer dependability with watering which can be easily adjusted to deliver full benefit with minimum water consumption. Manual watering does not allow this.
Thus, for condominium estates, it is strongly recommended to switch to Auto Irrigation Systems. By using a drip line, we can save water up to 60-70% than Manual Watering.

It is advisable to get your irrigation controller connected to a rain sensor. There is a sponge-like material inside the rain sensor which absorbs rainwater when it rains, making it heavy. As the sponge absorbs more water, it will sink and activate a pressure pin below it, which will send an electrical pulse to the controller, telling it to stop watering. The rain sensor will then automatically reset when the sponge dries out.

Not to worry, if you have already bought the equipment and you are unsure of what to do, simply call us! We will come down to your estate for a site visit, make some measurements and understand better from you on what you expect the outcome to be.

You will only have to provide us with a scale plan of your area. Upon our site study, we will give you a quotation for the installation and the maintenance of your system.

The most important thing to do is to meet our irrigation specialist on-site for a site walk and for us to better understand the landscape area.

This is important because, on-site, our irrigation specialist will then be able to have a full picture of the areas which can or cannot be adjustable when preparing a proposal for you.

On-site, we will be able to help the client save a significant cost on other aspects of the projects such as the location to have power access, which method of running the irrigation pipes will help you save cost and even suggest you on the pump size to save cost.

Once the survey is complete, we will offer you the full layout plan of the system and requirements. Once we have finalised all documents and the decision is made to award the project to Prince’s, we will then take over from there and build the irrigation system on your behalf.

Yes, it is 100% possible.
All you have to do is give us a call so we can arrange for a site visit and access the situation to offer you a proposal.

No, not at all.
A good irrigation specialist, when installing the system, will blend the system easily into your landscape and thus, also making it very unobtrusive.

Yes, you can.
For a comprehensive irrigation system where there are water pump and tanks involved, all you need is to get a fertigation system which has a liquid chemical fertiliser.
This liquid fertiliser will then be introduced into the irrigation water pipes and evenly distributed via sprinkler systems or drip systems. Thus, saving you a lot of money on landscape maintenance.

Simply purchase a pressure regulator which fits the drip system. Thus, preventing the uneven pressure fluctuation from happening. If unsure how to install, please give us a call, and we will gladly assist you with a minimum fee of installation.

An experienced irrigation specialist who does the designing of the system, installation and maintaining the system will have no issue lasting up to 20 years and beyond.

If the installation is done right from the start, the maintenance will not cost you a lot. Realistically, the maintenance should be charged cheaper to clients and limited to regular visual inspections to detect any faulty irrigation components.

As technology has vastly improved throughout the years, irrigation systems and parts like controllers and vales are now highly reliable. However, materials such as driplines, sprinklers, pumps etc. will wear and tear over time. Thus, it is always advisable to contact us so that we can offer you a competitive package and maintain your system for years to come.
