Your water system, designed around your site.

We design, build and maintain the plants that treat, purify and move water for government, defence and institutional clients. Most of our work happens in buildings that stay fully occupied throughout.

Water reuse

The cheapest water is the water you already paid for

Delhi supplies water it does not have. Treating waste water on site and putting it back to work is the fastest thing a building can do about that, and it usually pays for itself.

  • Treated waste water reused for flushing and gardens
  • Cooling tower make-up and vehicle washing
  • Reject water recovered instead of drained
  • Systems that waste far less than a conventional plant
  • Pumps and aeration sized to the real load
  • Plants held at design performance year after year

How we design for reuse

About Puretron

Questions

Questions we are asked before every job

Which areas do you work in?

Our office is in Mayur Vihar, Delhi, and most of our work is across Delhi NCR, including Noida, Gurugram, Ghaziabad and Faridabad. We also take project sites elsewhere in India and supply products nationwide.

Do you work with government departments?

Yes. We have worked with central government departments, CPWD, aviation and paramilitary establishments since 1986. We hold Udyam MSME registration and prepare tender and GeM documentation, bills of quantity and technical submissions in departmental formats.

What size of work do you take on?

From a single water purifier to a complete treatment plant for a township. Small maintenance jobs are done to the same standard as large contracts.

How do you decide which system a site needs?

We test the water and look at the site before recommending anything. The right system depends on what is in the water, what the water is for, how much space there is and who will run it. A plant specified without that test will underperform from the day it is switched on.

Do you maintain plants that someone else installed?

Yes. We take over plants of any make after a condition survey and a written report on what it will take to bring them back to the performance they were designed for.

How quickly do you respond to a breakdown?

Telephone diagnosis the same day, and site attendance within the response time agreed in the contract. We hold spares for what we supply so a failed part does not become a long wait.

Can treated sewage really be reused in our building?

Yes, for flushing, gardens, cooling tower make-up and washing. It is not used for drinking. The plant is designed to meet the standard your state pollution control board applies to the use you intend.

What do you hand over when the work is finished?

Joint measurement records, test and commissioning certificates, material certificates, drawings where they apply, an operating and maintenance schedule, and a snag closure record.

Have a site that needs looking at?

Send drawings, a tender document or a plain description. We visit the site, work out what is actually required and come back with a clear estimate.
