Sewage Water Treatment Plant

Sewage water treatment plant is used to filter the domestic waste water to environmentally safe treated water.

Sewage water is black water, it contains all types of waste water of households. SEWAGE TREATMENT is process of removing containment from waste water, primarily from houshold sewage.


Grey Water Treatment Plant

Grey water is waste water generated through kitchen, bathroom, hand sink, shower, washing machines, etc. but without toilet water.


Solar Water Heater System

Solar water heating system is used to heat the water and this heated water is used for bath purpose.

This system does not required electricity. Maintenance is very low. Solar water heating system is working on thermo-siphons technology.


Solar Lighting System

Solar lighting system is power generating system, it generates electricty from solar energey. Mainly this sytem is useful in remote areas where electricity is not available.

It has two types

  • 01 On-Grid Solar System

    On-grid means your solar system is tied to your local utility's GRID. This is what most residential homes will use because you are covered if your solar system under or over-produces in regard to your varying energy needs. All this means for you is that your utility system acts as your battery space. If you are producing more energy with your solar panels or system than you are using, the excess energy is sent to your grid's power company, allowing you to build credit that you can cash out with at the end of the year, in a process called net metering. Being grid-tied is beneficial because you don't have to buy an expensive battery back-up system to store any excess energy.

  • Being off-grid means you are not connected in any way to your grid's power system or utility company. This is appealing because you are 100% self-sustaining your energy use. However, there are disadvantages because off-grid systems require you to purchase back-up battery which can be expensive, bulky, and not very environmentally friendly which defeats the purpose of going solar (save money and live greener)


Water Treatment Plant

Water Treatment Plant (RTP) is used to remove hardness of water, i.e. used for utility purpose.

Our primary source of water is Municipal Corporation and secondary is borewells, and borewell water is hard water. So we need to minimize its hardness to make it useful.


Reverse Osmosis (RO) Plant

RO filteration process is the tertiery filteration process.

This RO filtered water is used for drinking purpose. RO process removes TDS, hardness like all hazardous containment from the raw water and give filtered water, thats good for drinking.


Online Monitoring System

An online monitoring system for sewage treatment plants (STPs) is a system that continuously measures and records the quality of the effluent discharged from the STP.

This information can be used to ensure that the STP is operating effectively and that the effluent meets the required standards.
