Telangana May Mandate Treated Water Reuse in Big Projects

Telangana May Mandate Treated Water Reuse in Big Projects, and if the proposal moves into binding rules, apartment buyers in Hyderabad will have one more serious checkpoint before booking: does the project really have the STP capacity, reuse network and maintenance discipline to handle treated wastewater for years?

The news matters most for large gated communities coming up in Kokapet, Narsingi, Tellapur, Kollur, Bachupally, Kompally, Shankarpally and along the ORR growth belt. These are not small buildings with 20 flats. Many new residential projects are selling 500, 1,000 or even 2,000-plus units in phases. Water demand is huge, tanker dependence is already a pain point in summer, and treated wastewater reuse is no longer a brochure line. It can directly affect monthly maintenance, landscape quality, flushing systems and resale value.

In our experience, buyers ask about clubhouse size, UDS, carpet area and possession date. Very few ask for STP design capacity, treated water reuse plan or who will maintain the plant after handover. That habit may have to change.

Telangana May Mandate Treated Water Reuse in Big Projects: what is being discussed?

The proposed direction is simple: bigger residential and mixed-use projects may have to treat wastewater on-site and reuse it for non-drinking purposes such as flushing, landscaping, road washing, construction curing and common area maintenance. The exact thresholds, compliance timelines and enforcement method will become clear only when the government issues final rules or department-level instructions.

But the market signal is already clear. Telangana is pushing urban projects to reduce fresh water consumption. For Hyderabad, this is not just an environmental issue. It is a planning issue. Western Hyderabad is adding high-density housing across Gandipet mandal, Serilingampally mandal, Ramachandrapuram mandal and Shankarpally-side villages. Northern clusters around Medchal, Quthbullapur and Dundigal are also seeing large apartment formats. When thousands of new toilets, kitchens and gardens come into use, old water assumptions fail quickly.

Large builders already mention sewage treatment plants in project amenities, especially for RERA-registered gated communities. The gap is usually not in the promise. The gap is in actual capacity, plumbing segregation, regular testing, sludge disposal and yearly maintenance budgets.

Telangana May Mandate Treated Water Reuse in Big Projects: why buyers should care

For a buyer, treated water reuse sounds like a technical subject. Actually, it hits the pocket. If an STP is undersized or poorly maintained, the association may face smell complaints, pump failures, extra tanker bills, penalties, replacement costs and disputes between residents and facility management teams.

Take a simple calculation. If a society increases maintenance by just ₹1 per sq ft to manage better STP operations, a 1,500 sq ft flat pays ₹1,500 extra per month. That is ₹18,000 per year. Over 10 years, without even counting escalation, the cost is ₹1.8 lakh. For a 2,000 sq ft flat, the number becomes ₹2.4 lakh over 10 years. This is why water infrastructure should be treated like lifts, fire safety and basement ventilation, not like a minor utility room hidden behind the tower.

Before booking, buyers should check the project on the RERA Project Lookup. RERA filings may show sanctioned plans, project details, phase-wise scope and promised amenities. If the project is sold as an eco-friendly or water-efficient community, ask the sales team to show the approved STP location and capacity, not only a colourful master plan.

What to check in the STP and reuse plan before buying

Here is the practical due diligence list I would use for a large Hyderabad residential project:

• STP capacity: Ask capacity in KLD, which means kilolitres per day. Match it with the number of flats, expected occupancy and commercial/common area load.
• Separate plumbing: Treated water used for flushing needs a separate network. Retrofitting later is expensive and messy.
• Reuse commitment: Check whether treated water will be reused for flushing, gardening and common washing, or simply discharged after treatment.
• Odour control: Visit completed projects by the same builder. Poorly maintained STPs usually announce themselves by smell.
• Power backup: STPs need continuous operation. If pumps stop repeatedly, treatment quality suffers.
• Annual maintenance contract: Ask who will operate it after handover and what cost is assumed in maintenance estimates.
• Testing records: For ready-to-move projects, resident associations should insist on treated water quality reports.

Also look at land and approval basics. A project can have a good water story and still carry land risk. Telangana has a large prohibited-property database under Section 22-A, with 147,934 prohibited properties recorded. Before paying a booking amount, use the Section 22-A Prohibited Property Check, especially for projects near old village boundaries, assigned land pockets or disputed survey numbers.

Hyderabad localities where this issue will show up first

The impact will be most visible in high-rise and high-density corridors. Kokapet and Narsingi in Gandipet mandal have premium towers with heavy amenity loads. Tellapur, Osman Nagar and Kollur near Ramachandrapuram and adjoining growth zones are seeing large phased communities. Bachupally and Miyapur-side markets attract IT employees buying mid-to-premium flats. Kompally, Gundlapochampally and Medchal-side projects often advertise bigger open spaces, which means landscaping water demand can be high.

In villa and plotted-layout markets like Mokila, Shankarpally and Chevella-side pockets, the issue is slightly different. Buyers should ask whether individual units depend on borewells, common STPs, decentralised systems or future association-managed facilities. A layout with wide roads and green areas may look attractive, but water reuse planning decides how sustainable those green areas remain after handover.

Land-use and planning checks also matter. Before assuming that a project’s water reuse plan is enough, verify the land-use context through the Land Use Zone Finder. For large plotted or apartment projects, also use the FSI/FAR Calculator to understand how built-up intensity relates to site area. Higher density generally means higher wastewater generation and higher operational discipline.

Cost impact: green feature or maintenance burden?

Good STP systems cost money. Poor STP systems cost more later. Developers may have to budget for better treatment units, dual plumbing, storage tanks, monitoring systems and trained operators. Some of that cost may be built into the apartment price. Some may come later through maintenance.

My view is that serious buyers should not reject a project because maintenance is slightly higher for genuine water infrastructure. In a water-stressed summer, a well-run reuse system can protect residents from tanker chaos. But if a builder uses sustainability language without giving technical details, that is a red flag.

Documents and questions buyers should put in writing

Verbal answers from sales teams are not enough. Put these questions by email or WhatsApp and keep the response:

• What is the approved STP capacity in KLD for this phase and for the full project?
• Is treated water connected to all flats for flushing?
• What percentage of treated water is planned for reuse within the project?
• Who maintains the STP until association handover?
• What monthly maintenance amount has been assumed for STP operation?
• Are there any previous pollution control notices or complaints in the builder’s completed projects?

For resale apartments, ask the association for maintenance bills and STP service records. Also run an Encumbrance Certificate Search to check property transaction history and charges. If you are buying land for a large residential development, use the Property Verification Tool before moving to agreement stage.

What builders should prepare for

Developers who already treat STP as core infrastructure will have an advantage. They can show capacity, reuse mapping, quality reports and operating cost estimates. Smaller builders entering bigger formats may feel pressure because compliance is no longer only about sanction drawings. It is about long-term facility performance.

We have seen Hyderabad buyers becoming sharper after RERA, Dharani-related land checks and repeated layout approval issues. Water reuse may become the next due diligence habit. Just as buyers now ask for HMDA approval, SRO details, link documents and pahani references in land deals, apartment buyers may start asking for STP drawings and reuse commitments.

The proposed rule, if implemented well, can improve groundwater discipline and reduce fresh water pressure. But enforcement must be practical. Authorities should avoid only paper compliance. Periodic testing, transparent reporting to residents and penalties for non-functional systems will matter more than another line in the approval file.

Bottom line for Hyderabad homebuyers

Treated wastewater reuse is moving from a sustainability claim to a buyer protection issue. In large projects, it can affect comfort, maintenance, resale and the daily living experience. Before booking in Kokapet, Tellapur, Kollur, Bachupally, Kompally or any fast-growing Telangana corridor, check the STP plan with the same seriousness as title, RERA status and registration cost.

A good project will answer clearly. A weak project will avoid specifics. That difference tells you a lot.
