STP Plants in Residential Complexes

Published

on

With a view to better manage available resources and reduce environmental damage, environmental laws now make it mandatory for apartment and apartment complexes to have an STP plant on premises. In a number of Sates this rule has now mandatory for all such complexes, both new and existing.

However, some apartment owners and residential complexes have still been hesitant to adopt this rule, despite the fact that STP plants manufacturer India are today designing some of the most economical plants. Some dismiss the idea because of extra costs, while some are ignorant of its necessity. Some deem it unnecessary because either they are connected to a municipal waste system or because they think it is not needed.

Why Private STP Plants?

The reason for a private STP plant are many. Some of these are:

Inadequacy of municipal system: The municipal system in our country is simply not enough to deal with the amount of wastewater that is generated everyday. In fact, some studies found that wastewater treatment for Class I and Class II (the biggest wastewater generating centers) was as low as 31%.

Even in plants that are operational, many were found to be badly managed or simply inefficient/inadequate. This is clearly a catastrophic condition where our public systems simply cannot keep up with the requirement. This has made it imperative that we manage wastewater at a local level.

Autonomy: Even before it became a legal necessity, many residential complexes had already taken steps to install STPs. This gives them more autonomy over their wastewater management. With a locally managed plant, complex do not have to depend on municipal authority to take corrective actions when there is some breakdown. They can also make sure that the plant is functioning at optimum level at all times.

Legal necessity: For those who are still vacillating over its need, the truth is that STPs may soon become a legal necessity across India, if it is not already so in your state. Many State governments have already made STPs compulsory in new units. A number of States have also asked all existing residential bodies to comply.
This means that sooner or later you will have to build a plant on premises. It then makes sense to contact an expert STP plants manufacturer India to ensure that you have a running plant before it is too late.

Alternative source of water: Apart from their legal and environmental necessity, STPs are actually beneficial for a residential complex. An STP provides an alternative source of water – treated and cleaned in the plant – that can be used for other purposes, such as watering plants, flush water etc.

In large complexes, which house hundreds (sometimes even thousands) of residents, such an advantage is simply too important to give up. Increasingly, we find that water supplied by municipal bodies in big cities fails to meet the desired requirements. An alternative source of water that can take care of secondary requirements becomes extremely welcome.

What kind of STP will work for residential complexes?

The decision on the kind of plant to be constructed should be taken after careful consideration. The construction of an STP is a considerable investment. There are many ways of making this economically sustainable, but it is a fairly permanent structure. So, getting it right in the first go is important.

Closed or open: Sewage treatment plants can be closed, open or partially open. Open plants are not recommended for residential areas, especially densely populated areas. This is because sewage treatment through biological means often produce methane, which gives out an unpleasant odor. This smell can reach miles. In an open or partially open plant, the odor can be very off-putting. This makes it a complete no for a residential complex.

Additionally, the plant should be located away from car parking area. Since, methane is a highly combustible gas, any spark can cause fire.

Manual or automatic: For smaller apartment complex, an automatic system is recommended. Manual systems need supervision and operational personnel, which is not always possible in a small complex. While a manual system is cheaper to install, it is more expensive to operate. Bigger complexes can made budgetary allocation for the personnel, but for a smaller society a one time allocation makes more sense.

There are a number of designs available today for STPs. Contact a competent STP plants manufacturer India for the best options available to you.
