With the use of a quick coupling system, an easy ad-hoc drip irrigation system can be installed onto any existing landscape.
To water the landscape, a simple hose of sufficient length can be used to connect the system to nearby tap.
Once work is done, the hose can be removed and kept elsewhere, keeping the entire watering process neat and tidy.
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 filter cleaning, and other irrigation items we have installed.
In Singapore, approximately 5 Litres of water is required for 1 m² shrubs planting area in one day due to the evapotranspiration rate and climatic condition.
Manual watering by using Hose
Irrigation efficiency of Manual watering – 30% (Due to infiltration rate, field capacity, soil type)
So, water requirement for 1 m² area per day = 5 Liters * 30% = 16.67 L/ m²/day
Manual Watering by using Hose
Irrigation efficiency of drip irrigation – 100% .
So, water requirement for one m² area per day = 5L * 100% = 5 L/ m²/day
• Manual Watering Breakdown
For 4,727 m² area:
16.67L* 4,727m² = 78,705 L/ day = 78.8 m³/day
Average rainy days = 160 days in a year
So average irrigation days = 365-160 = 205 days
Total water usage per year= 78.8m³ x 205 days= 16,154 ?m³/ year
And need to consider 10 % wastage of water during irrigation
So total water usage per year = 17,769.4 m³/ year approx.
• Drip Irrigation Breakdown
Auto drip irrigation area 2,030 m² area:
(5L x 2030m²) = 10,150 L/ day 10,150L= 10.15 m³/day
Total water usage in a year = 10.15 x 365 = 3,704.75 m³/ year
Total water usage in a year = 13.48 x 205 (no rainy day) = 2,763.4 m³/year
Total water usage of Drip irrigation system= 3,704.75+2,763.4 = 6,468 m³/ year aprox.
So, we save = 17,769.4 m³– 6,468 m³/ = 11,301.4 m³ per year by using drip irrigation.
• NEWater Savings
If use potable water for irrigation
The unit rate of potable water= S$2.74/m³ as per PUB
So can save, 11,301.4 m³ x S$2.74 = S$ 30,965.84?/ year
If using NEWater for irrigation
The unit rate of potable water= S$2.33/m³ as per PUB
11,301.4m³ x S$2.33= $41,402.70/ year
So can save S$ 26,332.26/ year
FAQs About Our Irrigation Systems In Singapore
When Is The Best Time To Water My Plants?
It is always best to water early in the morning before the sun rises.
In the early morning when the sun is not scorching hot, there is less evaporation occurring and thus, allowing water to be soaked into the ground and absorbed by the plants’ root system.
What Is A Sprinkler System?
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:
– 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
– 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.
– 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 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.
What Is A Drip System?
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:
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.
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:

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 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.
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.
(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 are mainly two types of online drip, and inline drip, it allows water to deliver the land by drop by drop
What Is A Watering Program?
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
How Much Does A Completed Irrigation System Cost?
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.
Is It Essential For A Landscape To Be Divided Into Different Zones?
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.
Will An Auto Irrigation System Use More Water Than Manual Watering?
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.
How Will The Irrigation System Know When To Stop When It Rains?
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.

Will My Landscape Look Unsightly If I Install An Irrigation System?
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.
Can I Have Fertiliser Inside My Irrigation System So I Can Save On Landscape Maintenance?
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.
I Have Up And Down Landscape Gradients/ Hanging Baskets And Pots, And There Is An Existing Irrigation System That Supplies Water. The Pressure Fluctuates Severely. What Should I Do?
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.
How Long Can My Irrigation System Last?
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.
How Much Maintenance Is Required For An Irrigation System?
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.

Yes, of course.
Imagine having someone helping you to do watering once every morning before sunrise and once in the evening. You have the full flexibility to spend your valuable leisure time to water yourself. Even when you are travelling for a few days, the system will continue watering automatically.
Why Do I Need To Fork Out Excessive Money Just For The Irrigation System When Manual Watering Does The Job?
Yes, manual watering does the job. But it also adds on to your water utility bills. Manual watering is not a smart system as it has no controller telling it when to run or how much water pressure to apply. An irrigation system does all the work for you and helps you save money up to approximately 60% of water utility bills.
