The City of Surrey intends to provide a minimum operating pressure of 28 metres (40 psi) at street level during peak demand periods. This targeted pressure is made possible by the nine pump stations (link to Pump Stations), which supply water to over 80% of Surrey’s residents. Lower elevation areas are serviced by the residual pressure from GVWD transmission mains.
The size and topography of Surrey means it needs of eight pressure zones and roughly 150 pressure reducing stations. The pressure varies according to demand, elevation, distance from the source, and water main size.
The City of Surrey uses a computer hydraulic model to estimate the available water pressure and to retrieve information on upgrades needed to meet minimum pressure requirement as Surrey develops.
Water pressure may become too low to have the plumbing fixtures working efficiently. This most often happens in the upper floors of multi-storey buildings located in high elevation areas. Consider installing private booster pumps to maintain suitable pressure.
Properties located at low elevation areas may experience high water pressure. It is important that owners maintain a functional household pressure reducing valve to regulate the water pressure prevent plumbing fixtures, like hot water tanks and pipes, from damage and leaks. Be sure the correctly set and regularly maintain the pressure reducing valve to keep it working properly.
The City operates nine pump stations to provide adequate pressure to all customers, and for fire protection and fire fighting. Water pump stations are equipped with intrusion alarms, exterior lighting, locks, and fencing to ensure the security of water system.
