Sultanpur sits in the same farmhouse belt as Chattarpur and Ghitorni, and pools here face the full swing of the Delhi year: 45°C summers, a violent monsoon, dust-heavy autumn and cold winters where the pool is barely used. Each season needs a different hand on the water.
March to June: peak demand
Ultraviolet load destroys free chlorine fast, and evaporation concentrates dissolved solids. This is the season for tighter sanitiser checks, cyanuric acid within range so chlorine is protected without being locked up, and weekly filter attention. Expect the highest chemical consumption of the year — a good vendor tells you that up front rather than surprising you with a bill.
July to September: monsoon
Rain dilutes sanitiser and drags pH and alkalinity around, while runoff carries phosphates and organics straight into the water. Two things go wrong here: owners stop servicing because "nobody is swimming", and circulation hours get cut to save power. That is exactly how a pool turns green in ten days. Keep the pump running and keep testing.
October to November: dust and debris
Post-monsoon Delhi air is heavy. Skimmer baskets fill quickly, filter pressure climbs, and clarity drops even with correct chemistry. Backwash discipline matters more than chemicals in these weeks.
December to February: low-use season
Cold water slows algae, but it does not stop scaling or equipment corrosion. Keep circulation on a reduced schedule, hold pH between 7.2 and 7.6 to protect plaster and metalwork, and keep calcium hardness in range. Winter is also the right window for equipment servicing, pump inspection and any tile or grouting work.
Documentation across the year
Twelve months of logged readings turn into something valuable: a trend line. Rising TDS, creeping hardness or a slow drift in alkalinity are visible long before they become expensive. Every SwimCompany visit is logged and summarised in your dashboard.
