SEWAGE TREATMENT PLANT (STP) If you don’t treat the waste from the water before discharging it into rivers and various other water bodies, you may have to face some severe consequences. Sewage treatment is when toxins, pollutants, and contaminants are removed from the sewage to produce clean water reused later on for the environment. It plays a vital role in conserving the environment. Therefore, it becomes necessary for us to know the advantages and disadvantages of installing Sewage treatment plants. Sewage Treatment Plant system initial cost tentatively 4,550,000/= taka only. 1m3 Advantages of Sewage Treatment Plant 1. Time-Efficient: Gone are the days when sewage was cleared manually by the workers. With the advent of the latest technology, everything has gone exceptionally smoothly. A sewage treatment plant can treat large amounts of sewage quickly, making it more time-efficient. Apart from this now, wastewater is filtered so that it can be reused for other purposes. 2. Occupies Meagre Space: Do you have the conception that plants and devices take huge spaces? But don’t worry, the sewage treatment plant occupies very little space, and hence it’s convenient for you to set up at your big or a small store. They are compact and easy to transport. 3. Simple and easy installation: Sewage treatment plants do not have a complex structure for installation. They are straightforward to install, have low plant operations. They can be installed even above the ground and are very reliable. 4. Eco-friendly: STP’s are eco-friendly. They reduce the risk to public health and the environment. It has a well-proven technology to offer reliable performance at all times. The most significant advantage of STP is that they preserve the natural environment against pollution at all times. 5. Re-used water: Sewerage treatment plant finally produce treated waste water which water use gardening, car wash, toilet commode flush and road cleaning. Disadvantages of Sewage Treatment Plant 1. Continuous Power Supply: The sewage treatment plant’s operating system requires an endless amount of electricity to operate. In the absence, it can potentially stop working and even cause a few problems. 2. Leaves an Environmental footprint: Though Sewage treatment plant are designed to be eco-friendly, some facilities still leave an environmental impression when water is treated. Because the organic waste treated needs to go somewhere, and sometimes it causes harm. 3. Maintenance: A STP requires annual maintenance to check its proper functioning. If you fail to incur maintenance costs at the end of the year or forget to maintain it, you probably have missed out on something important.
SEPTIC TANK SYSTEM A septic tank is installed under the ground away from your living space. Whenever you flush a toilet or run the sink in your home, the water being used is directed into the septic tank by way of underground pipes and the waste and water are then separated. The water itself is removed from the septic tank into the ground and the waste is separately collected until it is time for routine maintenance and it is pumped out. A septic tank requires you to give focus to the amount of water you are using at any one time, which actually forces many people to be more efficient since they do not want to overwhelm or overwork their septic system. Cost of construction for 1500 person tentatively 12, 75,000/= taka. Per square feet 850/= taka. The Advantages of a Septic Tank System A septic tank tends to be more cost efficient since extensive underground sewer lines are quite costly to build, install and maintain. A septic tank, on the other hand, is much cheaper to install and does not require monthly maintenance costs to homeowners. Another advantage of a septic tank is the fact that they are quite durable and when properly maintained rarely ever need to be replaced. A final advantage of a septic tank is the fact that they are environmentally friendly. They do not contaminate water supplies and they actually remove any bacteria before the water is released into the ground or soil. In addition, all of the recycled water is absorbed by various types of plant life nearby making it quite environmentally friendly. BOOSTER PUMP: Water booster pumps are required when the pressure and flow rate delivered at individual plumbing fixtures fail to meet code requirements. However, before installing the system it is important to confirm if low pressure is not due to other factors, such as clogged or undersized piping. Building top four floor toilet fixture pressure not sufficient so need to booster system for minimum pressure required.
