Plastic water storage tank business is highly lucrative. You might decide to go into manufacturing plastic water tanks or wholesale of established brand.
They come in various attractive colors, shapes and capacity. Despite being slightly less pricey than aluminum tanks they are durable rugged and aesthetically pleasing to the eye.
The most popular cost effective options available in the market are plastic and polyethylene water tanks. Other non plastic water tanks available in the market are aluminum, steel or Iron and fiberglass.
There are differ methods used in manufacturing plastic water tank such as the rotational mold process. The different methods are highly effective, creating rugged and durable tanks that last several years.
 Before you start your plastic tank business you need to write a business plan. Other considerations are sector of interest either manufacturing, wholesale or distribution business.
Manufacturing plastic tanks is capital intensive and you need adequate funding. Other requirements are trained machinery operators, marketing staff, drivers, cleaners and adequate factory space.
Why Plastic Water Tanks are in High Demand
Most homes and factories need a storage facility for water. This is especially true in developing countries such as Nigeria, Ghana, and Sudan.
Many countries especially in West Africa still grapple with low water supply. Private homes and companies need to provide their own water source through boreholes and wells.
They need to store water for later use in storage facilities making plastic water tanks popular. Many rural communities and farms need tanks to provide water for plants, animals and human consumption.
 More reasons for the increased demand and popularity are easy handling and installation. The water tanks are light weight when empty and are very durability.
 Plastic water tanks can last thirty years without corroding or maintenance. Another favorable quality of the tank is the ability to withstand UV rays.

Write a Business Plan
Before you start the enterprise write a comprehensive business plan. If you don’t know how to write a business plan on hire professional writer.
 Another option is to learn from books, e-books and other online resources. Once you have your business plan carry out a feasibility study of your area.
Distribute survey forms to understand the customer’s needs and preferences. Focus on competitors, pricing, product and earning power of host community.
Locate the Plastic Manufacturing Plant
You need a big factory space to produce plastic water tanks. Plastic water tanks are big and need adequate storage facility.
Lease a very large warehouse with ample packing and storage space. The warehouse should have a good road network for movement of raw materials and finished product.
The factory can be located in urban areas or outskirt of town. Make sure you factor the cost of transportation when choosing a location. The closer too customers and raw materials the less transportation costs.
Financing the Plastic Tank Business
Your company needs major financing to get off the ground. You should approach several banking institutions in your locality.
Provide collateral, business plan and management structure to the bank. Provide some of the startup capital and insurance cover. To access loan you might be expected to open an account in the bank for easy monitoring and funding.
The Rotational Molding Process
A popular manufacturing method is the rotational plastic water tank molding process.  There are different methods of making plastic tanks such as the rotational molding process, blow molding process, injection molding process.  The rotational mold method involves a mold, different temperatures, mold rotation and pressure.
Why use Rotational Mold Method
The rotational molding method has many advantages over other methods. The method allows high production capacity, easy coloring and low production cost.
 It provides the ability to mould complex parts without assembling. Other major advantages include minimum wastage, high quality products, inexpensive molds and fast production time.
It is possible to produce a huge number of plastic tanks in a relatively short time.  You can also produce different storage capacity products and sizes.
How to Produce Plastic Tanks
To produce plastic tanks the raw material needs to go through processing. The raw polyethylene granule goes through a grinding process, mixed with concentrators.
The dust particles are further sorted by a cyclone to separate large granules. During the grinding process the temperature is controlled and regulated.
This is to prevent melting or binding of the particles. During the dry blending stage the quality of the finished product is determined.
 Additives such as stabilizers, modifiers, and antioxidants are added to the dry blender. The material is then feed to the rotational mould and heating.
The heat slowly melts and shapes the polyethylene plastic then cooling. Once the material has solidified and cooled the tank is removed from the mold.
Machinery and Equipment for Rotational Tank Molding
Machines needed for plastic water tank production are Owen single arm and three arm station machine, 360 movable moulds. Others are fire rock roll machine, rotational moulding plant and high speed mixture.
More are weighing machine, chain pulley and pulverized machine. You also need different moulds, test equipment, cyclone system, and feeder hopper.

Quality and Cost Considerations
Your product needs to pass a standardized quality check. Product quality and standardization is guided by local and international certifications such as SLS 935, SLS 659, SLS 147 and ISO 9001.
Costs of production include cost of raw material, purchasing equipment, leasehold, materials and labor. Others are overheads, net total, price of item and profit.
Marketing the Plastic Tanks
Manufacturers sell directly to wholesalers and retailers of plastic products. Major housing projects are also viable sources of interest.
Quality tanks will always attract good market interest especially if proper branding and advertisement are deployed. You need lots of advertisement in traditional print media and electronic media.
Offer high quality products, branding and discounts to attract patronage. Plastic tank sales are primarily focused on domestic markets. How to Start a PVC Manufacturing Business
