Route Optimization for Pool Service Companies: Serve More Pools in Less Time

Why Route Structure Matters

The number of pools a technician services in a day is bounded by two constraints: the total service time at each pool and the total drive time between pools. Service time per pool is relatively fixed by pool size and conditions. Drive time is variable and is directly determined by route structure.

Two technicians servicing the same number of pools with different route structures can have significantly different productive hours per day. A technician whose route is geographically scattered will spend a higher percentage of the day driving and a lower percentage actually servicing pools.

Geographic Clustering

Geographic clustering is the practice of grouping service stops that are close together on the same route. A route built around a single neighborhood or zip code has much shorter drive segments between stops than a route that mixes stops from across a large service area.

When adding new customers, geographic clustering means prioritizing customers whose address is already near existing route stops. A new customer one street away from an existing stop adds almost no drive time to the route. A new customer ten miles in a different direction adds significantly.

Day-of-Week Batching

Day-of-week batching assigns all pools in a geographic area to the same service day. Instead of servicing pools throughout the week across a wide area, the Monday route covers the north part of the service territory and the Tuesday route covers the south. Each day's drive time is minimized because all stops are in close proximity.

Batching also improves customer communication. Customers know their service day and can plan access accordingly. It simplifies scheduling one-time jobs and seasonal services because you know when the technician will already be in each area.

Calculating Route Efficiency

Route efficiency can be measured by dividing total service time by total time on route. A technician spending 5 hours at pools and 3 hours driving in an 8-hour day has a 62.5 percent efficiency rate. Improving route structure to reduce drive time to 2 hours raises efficiency to 71 percent and creates capacity for additional pools without extending the work day.

Route Building in Practice

Building an optimized route starts with mapping all existing pools and identifying geographic clusters. Stops that are naturally near each other should be grouped on the same route. If stops are scattered, consider whether some customers can be shifted to a different service day to improve geographic density.

New route software can assist with sorting stops within a route to minimize drive distance. Manual routing based on map knowledge of the service area is effective for experienced operators who know where traffic patterns create time loss.

Managing Route Changes

Routes change as customers are added, pause service, or cancel. Maintaining route efficiency as the customer base evolves requires periodically reviewing the geographic distribution of stops and reassigning customers between routes as necessary. An operator who consistently routes new customers geographically near existing stops will naturally maintain density over time.
