Water availability and quality in an apartment depend on decisions the developer made during construction: the size of the overhead tank, whether individual sub-meters are fitted, the pipe material used inside the flat, whether there is a sewage treatment plant to recycle water, and whether the project has a valid Metrowater connection or relies entirely on tanker supply. Buyers who ask these questions before booking make an informed decision; those who ask only after possession discover the answers through daily inconvenience. Water is an infrastructure item where the gap between a well-designed project and a poorly designed one is felt by every resident, every single day.

Prestige Medavakkam is a pre-launch gated apartment project by Prestige Group on Medavakkam–Sholinganallur Road. Our sustainable and green living guide covers rainwater harvesting, STP recycled water, and water-saving fixture choices in the context of green apartment living. This guide focuses on the practical water supply and plumbing checklist that every apartment buyer should work through before shortlisting a project.

Water Supply & Plumbing: Six Things to Check Before Booking

The table below covers the six water-related topics that matter most for apartment buyers in Medavakkam. Raise each of these with the developer's sales team and note the answers in the building specification document.

Metrowater, Borewell Backup and Upper-Floor Pressure

A Chennai Metropolitan Water Supply & Sewerage Board (CWSSB, commonly called Metrowater) connection is the foundation of a reliable water supply for any apartment project in Chennai. Medavakkam falls under CWSSB's service area, but supply schedules and volumes vary by locality and the capacity of the local distribution network. Before booking, ask the developer whether the project has an existing CWSSB connection or whether the connection is in process. In a project that is under construction, the connection may not yet be active but should be in the application pipeline. If the developer cannot show evidence of a CWSSB connection or application, treat this as a flag and investigate further before committing.

Most gated communities in Medavakkam supplement Metrowater with a borewell for periods when Metrowater supply is insufficient or interrupted. Borewell water quality in Chennai varies by depth and location; some areas have water that is suitable for non-potable use after treatment, while others may have issues with salinity or hardness. Ask the developer whether the borewell water is regularly tested and whether a water treatment system is in place. For upper-floor flats, water pressure depends on the capacity of the overhead tank and the pump output: visit the sample flat on the highest floor of the project and run the tap and shower during the site visit to judge actual pressure. Our apartment possession and handover checklist includes water pressure testing as one of the items to complete at the time of taking possession of the flat.

Bottom line: Confirm the CWSSB connection status and schedule; ask about borewell water quality and treatment; test water pressure on the top floors during your site visit.

STP Recycled Water, Individual Meters and Plumbing Specification

A Sewage Treatment Plant (STP) treats the community's wastewater and produces recycled water that is suitable for gardening, flushing toilets and washing vehicles. An STP meaningfully reduces the volume of fresh water the project needs for these non-potable uses. Tamil Nadu's building rules require an STP for projects above a specified size; confirm that the project's STP is approved, commissioned and sized for the full occupancy of the community at its planned completion. An STP that is sized for the first phase of a multi-phase project may be insufficient once all phases are occupied, leading to overflow and STP water shortages. Ask the developer about the STP capacity in kilolitres per day and the number of flats it is designed to serve.

Individual water sub-meters for each flat are a practical and equitable way to manage water billing in a gated community. Without individual meters, the total community water cost is split across all flats equally, regardless of actual usage. This means a family of five and a single occupant pay the same water charge, which is a recurring source of friction in residents' welfare association meetings. Confirm whether the project has individual meters during the site visit by asking to see the meter room and the distribution board for a sample flat. Our apartment maintenance and society living guide explains how water charges, maintenance charges and other recurring costs are typically structured and governed by the RWA. When moving in, record the meter reading in writing and photograph it; our moving-in and relocation checklist covers this and other move-in documentation steps in detail.

Bottom line: Confirm the STP is operational and sized for full occupancy; check whether individual water meters are fitted; note the plumbing pipe specification and the stopcock location during your site visit.

What to Check at Possession and After Moving In

At the time of taking possession of the flat, water-related checks are among the most important items on the snag list. Test every tap in the kitchen, bathrooms and utility area for flow and pressure; check that the WC flush works and that the cistern refills within a normal time; inspect under-sink plumbing connections for leaks; and verify that the floor trap in the bathroom drains without overflow. Note the water meter reading in writing and photograph it with a timestamp before signing the possession papers. A reading that is already high before you move in should be queried with the developer before acceptance.

After possession, maintaining the plumbing in an apartment is primarily the owner's responsibility for everything inside the flat boundary, while the society maintains the common water supply infrastructure including overhead tanks, pumps, main supply lines and the STP. Know the location of the main stopcock for your flat: it is the first thing you will need to find and turn off if a pipe bursts or a fitting leaks. Most flats have the stopcock in the utility area or near the main water inlet. If you are unable to locate it during the site visit, ask the developer's site engineer before you take possession. Having this information documented means you or your tenant can act quickly in an emergency without waiting for the society's maintenance team.

Bottom line: Test all taps, the WC flush and under-sink connections at possession; record the meter reading before signing; locate and test the main stopcock; understand which plumbing is the owner's responsibility versus the society's.

Conclusion

Water supply and plumbing quality in a Medavakkam apartment comes down to six things: the primary water source (Metrowater connection and its reliability), the borewell backup and water quality, pressure on upper floors, an operational and correctly sized STP for recycled water, individual sub-meters for equitable billing, and the pipe specification and stopcock location inside the flat. All six are checkable before booking and confirmable in the building specification document. Buyers who verify these details avoid post-possession surprises about water availability, pressure and billing.
