Abstract: We construct surface measures in a Hilbert space endowed with a probability measure $ \nu $. The theory fits for invariant measures of some stochastic partial differential equations such as Burgers and reaction-diffusion equations. Other examples are weighted Gaussian measures and special product measures $ \nu $ of non-Gaussian measures. In any case we prove integration by parts formulae on sublevel sets of good functions (including spheres and hyperplanes) that involve surface integrals.
