Many homeowners put off building their sewerage until spring or summer, thinking āit’ll be easier thenā. In practice, though, installing a biological treatment plant off-season is often not only possible but also worthwhile. If the work is planned properly and the weather and soil conditions are taken into account, the system can be installed in autumn or early winter too.
Shorter lead times and more flexible scheduling
Off-season it is usually easier to agree on an installation date, because demand is not as high as in spring. This means the work can be scheduled sooner and fitted more flexibly around the customer’s plans. As a result, there’s no waiting list and no rush to āget it done before summerā, when many people are trying to sort out their properties at the same time.
Ready for spring and less stress
Another benefit is simple: if the plant is installed off-season, the property is already sorted by spring. This is especially relevant if you are planning to have the house officially commissioned, carry out construction on the site, or simply want to avoid water, odours or overflows appearing in spring and having to ādeal with it urgentlyā.
When is off-season installation a particularly good choice?
Off-season installation is often chosen if:
- you want to sort out the sewerage quickly before spring
- you plan to pave or landscape the site in spring
- the discharge solution is clear and there is access for machinery
- you want to avoid spring āpeakā prices and busy schedules
What must you consider in autumn and winter?
For a quality installation, it’s important to assess the soil and site conditions. If the groundwater is high, a secure base and, if needed, anchoring must be planned. Access for machinery also matters, as does whether correct discharge can be ensured during periods of heavy rainfall.
