Why El niño Rains Create the Best Water Harvesting Season

El niño brings heavy and prolonged rain to Kenya, especially during the October to December short rains. As a result, rivers swell, fields flood, and millions of litres of free water flow away. Farmers who build and line a dam capture that water instead. Therefore, dam liners for el niño rain water harvesting turn a flood season into a full year of irrigation.

Once the rains stop, the dry months begin, and stored water becomes your most valuable farm input. Besides, unlined dams lose water through seepage into sandy and loam soils. A quality liner stops that loss completely. You should line your dam before the rains start, since wet soil makes installation harder. Get yourself prepared for the oncoming rains by calling +254790719020 and getting a quote for your dam liner installation from Aqua Hub Kenya today.

How Many Litres Can You Collect This Season?

One millimetre of rain on one square metre can give one litre of water. Based on this formula, 300 mm of rain over a one-acre catchment (about 4,047 square metres) delivers about 1.2 million litres. Catchments include roofs, compacted ground, farm tracks and drainage channels. Dam liners for el niño rain water harvesting hold that volume without seepage, so you keep every litre you collect.

Also, ground surface affects your harvest. Compacted soil sheds more water than freshly ploughed soil. Therefore, you should clear and shape the catchment so water flows straight toward the dam inlet. Consequently, you collect more litres from every millimetre of rain. Most importantly, you must size the dam to match the water your catchment delivers.

Price of Dam Liners for El niño Rain Water Harvesting

The price of dam liners for el niño water rain water harvesting in Kenya depends on the thickness and size of the material. Aqua Hub Kenya offers competitive rates for every size as shown.

How to Size a Water Harvesting Dam for Irrigation

Follow these steps to design your dam correctly:

1. Calculate daily crop water demand. Add up the litres your crops need each day.
2. Multiply by the dry days. For example, 10,000 litres per day over 120 dry days needs 1,200,000 litres.
3. Add an allowance. Add 20% for evaporation and handling, which brings the total to 1,440,000 litres (1,440 cubic metres).
4. Choose the dam dimensions. A dam 30 m long, 20 m wide and 3 m deep has a gross volume of 1,800 cubic metres. Sloped sides reduce usable volume, so you should dig a little larger.
5. Match the catchment. Divide your target volume by the expected rainfall to find the catchment area you need.
6. Order the liner. Liner area equals the dam surface area plus the anchor trench allowance.

Types of Dam Liners for El niño Rain Water Harvesting by Aqua Hub Kenya

Aqua Hub Kenya supplies HDPE dam liners in several thicknesses including:

• 0.5mm
• 0.75mm
• 1mm
• 1.5mm

The different thicknesses match different dam sizes and soil conditions. Larger dams and stony soils need thicker sheets. In contrast, smaller farm ponds work well with lighter sheets and thus cost less to get a dam liner installed for them.

You must always choose UV stabilized sheets. This is because sun exposure destroys cheap plastic within a short time. Additionally, check the seam strength of the liner before you buy it. Heavier sheets resist punctures and last longer.

To determine the size of the dam liner required, first measure the dam length, width and depth. Then, add additional material for anchor trench allowance so that the sheet covers the entire structure properly. Aqua Hub Kenya offers dam liners for el niño rain water harvesting that are cut to your dimensions, therefore you receive a custom fit.

Filtration and Treatment Before You Use the Water

Filtering the water harvested in the dam helps to protect your pumps, drip lines, emitters and crops. There are several steps required to make sure that your water is usable in these steps including:

• First, build an inlet silt trap so soil settles before water enters the dam
• Next, fit a screen filter or disc filter at the pump outlet. Drip systems need 120 mesh filtration, which allows emitters to stay clear for the whole season.
• Additionally, you can install a floating intake so the pump draws clean water from just below the surface.
• Shade nets over the dam surface cut sunlight, thus reducing algae growth and minimizing evaporation.

There are many benefits to having clean water in your dam. First off, clean water supports smooth fertifation, since fertilizer injection works best with filtered flow. Additionally, ensuring that your water is clean prevents harmful bacteria or chemicals entering the water supply. This is especially useful in cases where harvested rain water is being used for domestic purposes or to water livestock.

Aqua Hub Kenya supplies filters, pumps, shade nets and drip kits to go along with your liner. As such, you get all the materials you need to effectively use your stored rain water from the start. You can place an order for all these materials by calling +254790719020 or emailing info@aquahubkenya.co.ke.

Safe and Unsafe Uses of Harvested Water

Harvested rain water is safe for a variety of uses including:

• Irrigating vegetables, fruit trees, fodder, flowers and greenhouse crops
• Watering livestock
• Household use (the water must be filtered and treated before being used in the home, especially for drinking)

You should fence the dam and keep animals away from it. Additionally, chemicals and fuels should not be poured into the water. This helps to keep the water free from contaminants that could make it unsafe for use. You can also test your water once each season if you plant to supply it to the household. Safe handling keeps your family healthy while your crops grow.

Benefits of Dam Liners for El niño Rain Water Harvesting

Dam liners for el niño rain water harvesting protect your investment and your harvest. Here are the main advantages:

• Zero seepage: the liner holds every litre, even in sandy soil.
• Drought security: you irrigate through the dry months while neighbours wait for rain.
• Higher yields: steady water supply means consistent crop growth and better quality.
• Lower water costs: you stop paying for borehole pumping, trucked water or municipal bills.
• Long life: UV stabilized HDPE resists sun, weather and chemical exposure.
• Flexible use: the stored water feeds drip kits, sprinklers, greenhouses and livestock troughs.
• Reliable performance: quality sheets and strong seams keep your dam working season after season.

In addition, a lined dam raises the value of your farm. Buyers and lenders see a secure water source as a major asset. Therefore, a liner pays for itself quickly.

Installation Tips for Dam Liners for El niño Rain Water Harvesting

Proper installation protects the liner and extends its life. The following steps must be followed for proper dam liner installation:

1. First, remove stones, roots and sharp objects from the base and walls.
2. Next, compact the soil and smooth the surface so the sheet sits flat.
3. Then dig an anchor trench around the rim, place the liner without stretching it, and join any seams carefully.
4. Finally, backfill the trench firmly and fence the dam.

Also, install the inlet and overflow channels before the rains arrive. This allows floodwater to enter the dam in a controlled way and erosion stays low. For professional dam liner for el niño rain water harvesting installation, contact Aqua Hub Kenya by calling +254790719020.
